RESUMEN

BACKGROUNDS: Genetic variants in CF transmembrane conductance regulator (CFTR) gene causes cystic fibrosis (CF), a prevalent autosomal recessive disorder. More than 2000 variants in CFTR have been described as disease causative. This study aims to delineate the genotypic and phenotypic landscape of CF among people with CF (pwCF) followed at the largest CF center in Turkey. METHODS: We conducted a descriptive and retrospective analysis of 481 patients registered with the European CF Society Patient Registry and followed at Marmara University Selim Çöremen CF Center from 2015 onwards. Comprehensive CFTR analysis was utilized for genetic diagnosis. Besides the whole cohort, novel variants and complex alleles were also described. RESULTS: Our cohort exhibited a broad spectrum of CFTR variants, with 136 different variants detected, indicating substantial genetic diversity. The F508del variant was less prevalent in our cohort compared to US and European averages, which could reflect unique genetic and demographic characteristics of the Turkish population. Additionally, we identified nine novel variants in 12 alleles, which enhances the understanding of CF's genetic complexity in this region, and complex alleles in 32 pwCF. CONCLUSION: Our research underscores the heterogeneity of CFTR variants in Turkey and highlights the necessity for extensive genetic profiling particularly for diverse populations to provide effective personalized treatment strategies. It is crucial to understand the full spectrum of CFTR variants with the advent of CFTR modulators.

RESUMEN

Most foodborne salmonellosis outbreaks are linked to agricultural animal products with a few serovars accounting for most Salmonella isolated from specific animal products, suggesting an adaptation to the corresponding animal hosts and their respective environments. Here, we utilized whole-genome sequence (WGS) data to analyze the evolution and population genetics of seven serovars frequently isolated from ground beef (Montevideo, Cerro, and Dublin), chicken (Kentucky, Infantis, and Enteritidis), and turkey (Reading) in the United States. In addition, publicly available metadata were used to characterize major clades within each serovar with regard to public health significance. Except for Dublin, all serovars were polyphyletic, comprising 2-6 phylogenetic groups. Further partitioning of the phylogenies identified 25 major clades, including 12 associated with animal or environmental niches. These 12 clades differed in evolutionary parameters (e.g., substitution rates) as well as public health relevant characteristics (e.g., association with human illness, antimicrobial resistance). Overall, our results highlight several critical trends: (i) the Salmonella generation time appears to be more dependent on source than serovar and (ii) all serovars contain clades and sub-clades that are estimated to have emerged after the year 1940 and that are enriched for isolates associated with humans, agricultural animals, antimicrobial resistance (AMR), and/or specific geographical regions. These findings suggest that serotyping alone does not provide enough resolution to differentiate isolates that may have evolved independently, present distinct geographic distribution and host association, and possibly have distinct public health significance. IMPORTANCE: Non-typhoidal Salmonella are major foodborne bacterial pathogens estimated to cause more than one million illnesses, thousands of hospitalizations, and hundreds of deaths annually in the United States. More than 70% of Salmonella outbreaks in the United States have been associated with agricultural animals. Certain serovars include persistent strains that have repeatedly contaminated beef, chicken, and turkey, causing outbreaks and sporadic cases over many years. These persistent strains represent a particular challenge to public health, as they are genetically clonal and widespread, making it difficult to differentiate distinct outbreak and contamination events using whole-genome sequence (WGS)-based subtyping methods (e.g., core genome allelic typing). Our results indicate that a phylogenetic approach is needed to investigate persistent strains and suggest that the association between a Salmonella serovar and an agricultural animal is driven by the expansion of clonal subtypes that likely became adapted to specific animals and associated environments.

RESUMEN

The experiences of war and refugee status can alter intrafamily dynamics, with implications for family formation, including marriage. We use the nationally representative Syrian Migrant Sample of the 2018 Turkey Demographic Health Survey (TDHS-S) to conduct a duration analysis of marriage outcomes among Syrian refugees in Turkey, tracking women throughout their residence in prewar Syria (before the conflict began in 2011), postwar Syria (after the conflict began but before arrival in Turkey), and Turkey. We find that early marriage was more prominent among refugees who were unmarried at the time of migration than among those married before migration; the mean marriage age dropped from 19.6 in prewar Syria to 19.1 in postwar Syria and 18.1 in Turkey. Using the TDHS-S and prewar Syrian surveys, we show that this finding aligns with the observed declines in household income and young women's opportunity cost of marriage. Our duration analysis also reveals a notable shift from traditional arranged marriages to more modern marriage forms among refugees in Turkey. An intergenerational power shift might drive the shift toward nonarranged marriages. After arrival in Turkey, wealth and employment of parents decline among refugees. In contrast, Syrian youth in Turkey have higher age-adjusted employment rates than in prewar Syria. Moreover, nonarranged marriages increase more among demographic groups with stronger intergenerational power shifts than among groups with weaker shifts.

RESUMEN

BACKGROUND: The rising demand for palliative-care (PC) in Turkey, driven by cancer, has prompted increased attention since the national PC policy in 2010. Despite this, the healthcare system predominantly focuses on curative care, lacking PC integration. This is due to combination of administrative obstacles, fragmented coordination, education and training scarcity. Thus urgent strategies are required to address the growing PC gap. This qualitative study explores the perspectives of PC professionals and policymakers, providing valuable insights for national policy and program development. MATERIAL AND METHOD: This study employed an exploratory approach using key informant interviews. Interviews were conducted using semi-structured questionnaire. It sought to collect relevant contextual information in order to achieve its aim. Thematic content analysis was employed to examine and interpret the data. RESULT: Twenty-one participants, comprising nurses, specialists, and oncologists, were interviewed. The findings are encompassed by eight themes. 1) Integrated Care, highlights the importance of cohesive collaboration among diverse healthcare providers, social care services, and primary care systems to ensure comprehensive and effective care. 2) Meeting social care needs underscores significance of addressing a wide spectrum of patient requirements, including psychosocial support. 3) PC education emphasizes necessity of equipping healthcare professionals with the requisite skills and knowledge through comprehensive training. 4) Legalizing do-notresuscitate orders draws attention to the critical discussion surrounding end-of-life decisions. 5) Empowering communities recognizes bridging knowledge gaps among patients and caregivers. 6) Decision-Making underscores the importance of informed and collaborative decision-making processes. 7) Cultural considerations urge the adoption of culturally sensitive approaches. 8) Ongoing challenges shed light on persistent issues such as provider attitudes, and administrative hurdles. CONCLUSION: This study highlights essential factors for establishing an integrated PC program for cancer patients in Turkey. The existing healthcare system in Turkey offers opportunities for advanced PC. Successful implementation demands strategic actions to facilitate meaningful transformation.

RESUMEN

In recent years, suspicious deaths, often portrayed as "falls from a height," have been increasingly associated with femicides in Turkey. This phenomenon coincided with the official withdrawal process from the "Council of Europe Convention on Preventing and Combating Violence against Women and Domestic Violence" (Istanbul Convention). Our study aims to reveal the impact of Turkey's withdrawal from the Istanbul Convention on femicides and the yet officially unrecognized "suspicious female deaths." This research, conducted in a descriptive, cross-sectional epidemiological style, draws its population from records of suspicious female deaths and femicides that occurred in Turkey between January 1, 2020, and June 1, 2023. There has been a notable increase in the rate of suspicious female deaths. Additionally, a significant rise has been observed in the proportion of women who were employed, had children, and sought legal protection in these deaths. The study suggests a return to the Istanbul Convention.

RESUMEN

The seismic events that struck southern Turkey and Syria in February 2023, with magnitudes of 7.8 and 7.6 respectively, have significantly impacted the well-being of millions, particularly children and adolescents. This correspondence highlights the psychological repercussions faced by minors in the aftermath of the earthquakes, including anxiety, PTSD, and depression. Despite efforts to provide humanitarian aid, there remains a critical gap in addressing the psychosocial needs of affected children. With limited mental health resources in both countries, innovative approaches such as Psychological First Aid (PFA) interventions and telepsychiatry are advocated for efficient and scalable support. Additionally, safeguarding children from abuse and ensuring access to education and stable environments are paramount in post-disaster recovery efforts. This correspondence underscores the urgency for a holistic response to mitigate the long-term impact of seismic events on the vulnerable population in Turkey and Syria.

RESUMEN

Purpose: The aim of this study was to compare the menstrual symptoms and dysmenorrhea in university students who underwent Female genital mutilation/cutting (FGM/C), in Mogadishu, Somalia, and students who did not undergo FGM/C in Ankara, Türkiye. Methods: A comparative cross-sectional study design was used. Results: Among the participants with FGM/C, 88.5% were Type 1 and the age at FGM/C was 8 years. The pain severity was 6.20±2.54 in women with FGM/C and was higher than that of those without FGM/C (5.97±2.32), but no significant difference was found. Among those who had FGM/C, 66% had a menstrual duration of 3-5 days, while 52.0.% of those who did not have FGM/C had a menstrual duration of 6-8 days (p<0.05). While 85.1% of those without FGM/C had a menstrual cycle of 21-35 days, 35% of those with FGM/C had a menstrual cycle of less than 20 days (p<0.05). It was found that 95% of those who have undergone female circumcision and 90.2% of those who have not had dysmenorrhea (p<0.05). Painkillers were always used by 28% of women with FGM/C and 26.3% of women without FGM/C (p<0.05). The total MSS score of those who have not had FGM/C was 3.34±0.72 and the score of those who have had FGM/C was 2.91±0.74 (p<0.05). The negative effects sub-dimension score was found to be higher in the non-FGM/C group with 3.20±0.75, while the coping methods sub-dimension score was higher in the FGM/C group with 2.91±1.13 (p<0.05). Conclusion: FGM/C is still common in Somalia. Our study results showed that having FGM/C may cause differences in dysmenorrhea and menstrual symptoms. Efforts to increase students' effective coping with menstrual symptoms and dysmenorrhea are thought to be useful.

RESUMEN

OBJECTIVES: There is no sufficient data to provide a clear picture of out-of-hospital cardiac arrest (OHCA) across Türkiye. This study is the first to present the prognostic outcomes of OHCA cases and the factors associated with these outcomes. MATERIALS AND METHODS: The study was conducted in a prospective, observational, multicenter design under the leadership of the Emergency Medicine Association of Turkey Resuscitation Study Group. OHCA cases aged 18 years and over who were admitted to 28 centers from Türkiye were included in the study. Survived event, return of spontaneous circulation (ROSC), survival to hospital discharge, and neurological outcome at discharge were investigated as primary outcomes. RESULTS: One thousand and three patients were included in the final analysis. 61.1% of the patients were male, and the average age was 67.0 ± 15.2. Cardiopulmonary resuscitation (CPR) was performed on 86.5% of the patients in the prehospital period by emergency medical service, and bystander CPR was performed on only 2.9% by nonhealth-care providers. As a result, the survived event rate was found to be 6.9%. The survival rate upon hospital discharge was 4.4%, with 2.7% of patients achieving a good neurological outcome upon discharge. In addition, the overall ROSC and sustained ROSC rates were 45.2% and 33.4%, respectively. In the multiple logistic regression analysis, male gender, initial shockable rhythm, a shorter prehospital duration of CPR, and the lack of CPR requirement in the emergency department were determined to be independent predictors for the survival to hospital discharge. CONCLUSION: Compared to global data, survival to hospital discharge and good neurological outcome rates appear to be lower in our study. We conclude that this result is related to low bystander CPR rates. Although not the focus of this study, inadequate postresuscitative care and intensive care support should also be discussed in this regard. It is obvious that this issue should be carefully addressed through political moves in the health and social fields.

RESUMEN

PURPOSE: This study aimed to determine the forms of ocular and adnexal injuries and to examine the treatment modalities applied after two major earthquakes in Turkey on February 6, 2023. METHODS: Following the earthquakes, the medical records of 34 patients admitted with emergency ophthalmic complaints to Hatay Training and Research Field Hospital and Etlik City Hospital were retrospectively reviewed. Of these patients, 35 eyes of 34 individuals diagnosed with earthquake-related ocular and adnexal injuries were included in the study. Demographic characteristics were recorded, including ocular and adnexal findings, treatment modalities, and postoperative complications. RESULTS: Of the patients, 16 (47.1%) were female, and 18 (52.9%) were male. The mean age was 37.38 ± 17.3 years. The mean time from the earthquake to the first admission to the hospital was 3.82 ± 1.78 days. Initial and final best-corrected visual acuities (BCVA) were 0.54 ± 0.66 logMAR and 0.22 ± 0.41 logMAR, respectively (p = 0.0003). The initial and final BCVA of 2 eyes was no light perception. The most common forms of ocular/periocular injury associated with earthquakes were eyelid laceration (n:25, 71.4%) and orbital fracture (n:17, 48.6%). The most common accompanied systemic trauma was extremity/rib fractures (38.2). The most frequently performed surgery was the primary repair of the eyelid/canalicular (n:17, 48.6%). CONCLUSION: While earthquake-related ocular and adnexal traumas are relatively uncommon, understanding the specific injury types, promptly identifying cases requiring urgent intervention, and mastering effective treatment modalities are essential for minimizing the risk of severe permanent visual impairment in these patients.

RESUMEN

OBJECTIVE: The objective was to determine the prevalence and clinical correlates of nonmotor symptoms in Parkinson's disease patients in movement disorders outpatient clinics. METHODS: We enrolled all consecutive PD patients who visited our movement disorders outpatient clinics between January and December 2023; and agreed to participate in the study. In addition to the evaluation of demographic and clinical features, clinical scales, including the MDS-UPDRS, NMSS, and FOOGQ, were performed. RESULTS: Overall, we enrolled 163 PD subjects with a mean age of 63.9 ± 10.4 (F/M = 27/136). The disease duration was 3.5 (20) y [median (range)]. The median score of the NMSS was 41 points. The NMSs burden levels were severe in 25.2%, and very severe in 25.2% of the subjects. The subitems with the highest scores were sleep/fatigue, mood/cognition, urinary, and miscellaneous. The analyses within the patient group with newly diagnosed PD also revealed high NMSS scores. Comparisons of the NMSS between distinct PD stages revealed greater NMSS scores in the severe stage than in the mild stage (p = 0.001). Correlation analyses between the clinical scores and the NMSS scores revealed positive correlations between the NMSS scores and the scores on all the clinical scales including the MDS-UPDRS 1-4, and FOGQ. CONCLUSION: We reported the first data regarding the NMS burden in PD patients from Turkey. We found a high prevalence and severity of various domains of NMSs, most of which were sleep/fatigue, mood/cognition, urinary, and miscellaneous. More than half of the patients had severe to very severe NMS burden. Although NMSs were more common severe-stage disease, they were also prevalent in the subgroup with newly diagnosed patients.

RESUMEN

The mucilage event witnessed in the Sea of Marmara in 2021 has emerged as a prominent environmental concern, capturing public attention due to its detrimental effects on ecological, economic, and aesthetic dimensions. Addressing the multifaceted impacts of mucilage demands a nature-centric scientific approach, given its global ramifications spanning economy, public health, international relations, and tourism. Consequently, this study sought to explore alternative approaches for the removal of pathogenic enteric bacteria associated with mucilage occurrences, diverging from conventional methodologies. Specifically, the primary objective was to assess the efficacy of rhamnolipid and a bacteriophage cocktail in mitigating the proliferation of enteric pathogens within mucilaginous environments. During the study, 91 phage isolations were obtained from 45 water samples taken and 10 phages were selected for the broad host range and because of the efficacy tests, a phage cocktail was created with 5 phages. It was found that the mixture of rhamnolipid, phage cocktail and rhamnolipid-phage cocktail reduced bacterial load by 7-9 log10, 9-12 log10 and 9-11 log10 respectively under laboratory conditions. When the study was carried out in seawater, reductions of 4-5 log10, 3 log10 and 4 log10 were achieved. This study has shown that the combined use of rhamnolipid, phage cocktail and rhamnolipid-phage cocktail can be considered as the most effective natural solution proposal for reducing bacterial load, both in laboratory conditions and in sea surface water.

RESUMEN

This article builds on data and field work notes from two ethnographic studies conducted in two cities: Istanbul and Trabzon, Turkey. It examines the socio-political dynamics behind the prevalence and impact of conspiratorial narratives. We explore the emergence, circulation, and effects of these narratives and how they shape political orientations and mobilisation. We raise methodological questions about these narratives and propose researchers closely scrutinise them rather than dismissing them as illogical or incoherent. Our research reveals three novel relational and methodological insights derived from conspiratorial narratives. First, these narratives serve as sense-making tools during times of uncertainty. They provide accessible explanations for abrupt changes, and they rely and draw upon 'cultural repertoires'. Second, by challenging the mainstream narratives, they shape subjectivities; empowering narrators to act as agents. Third, how conspiratorial narratives circulate has implications for the dynamics of state-public relationships, often following the neoliberal logic, they portray political leaders as central figures in navigating complex decision-making processes. Our case studies demonstrate that actors, even in less powerful positions, may not necessarily antagonise the state. We underscore the methodological significance of these narratives for researchers, to examine actors' agency, group dynamics, and responses to everyday injustices.

RESUMEN

INTRODUCTION: Abacavir is among the first-line initial antiretroviral regimens for most patients living with HIV/AIDS (PLWHA). Although well tolerated, it is associated with hypersensitivity reaction (HSR), which is treatment-limiting and potentially life-threatening. HSR was shown to be associated with the class I MHC allele, HLA-B*57:01. In this study, we aimed to evaluate the prevalence of HLA-B*57:01 in PLWHA in Istanbul, Türkiye. MATERIAL AND METHODS: Five HIV treatment centers in Istanbul included all sequential treatment-- naïve, ≥ 18 years adult PLWHA, between December 2017- December 2021. Demographic, clinical, and laboratory data were collected at baseline and during treatment. HLA-B* 57:01 genotyping was determined with PCR-SSP. RESULTS: Eight hundred sixty-seven PLWHA were included (male:91%, mean age 39.6±11.1 years). 1.6% of patients were found to be HLA-B*57:01 positive. Among HLA-B*57:01 positive patients, 4 were initially given abacavir-containing treatment; they were switched to non-abacavir treatment upon the allele found to be positive. CONCLUSION: Although previous studies reported the HLA-B*57:01 prevalence of PLWHA in Türkiye as 3-3.6%, we have found the prevalence to be 1.6%. The current study includes higher numbers of patients than the previous studies. Furthermore, patients from all over the country apply to the centers in Istanbul; compared to the other studies, which involve patients limited to the relevant regions, it can be assumed that the number in our cohort is more representative of the country. In conclusion, the prevalence of the HLA-B*57:01 allele in PLWHA in this study is relatively low. With evident benefit in preventing abacavir HSR, HLA-B*57:01 should be screened in planning antiretroviral therapy.

RESUMEN

BACKGROUND: This study investigated the presence of dizziness and sleep quality in people affected by the earthquake disaster of 2023 in Türkiye and aimed to determine the relationship between dizziness and sleep disorders. METHODS: A total of 384 earthquake survivors who had no previous complaints of dizziness or sleep disturbance and who presented to the neurology outpatient clinic with complaints of dizziness or sleep disturbance after the earthquake were included in the study. Demographic information of participants and scales such as the Dizziness Handicap Inventory (DHI) and the Pittsburgh Sleep Quality Index (PSQI) were recorded. RESULTS: It was determined that the majority of the patients in the 18-35 age group had poor sleep quality and there was a significant difference in the PSQI score. Additionally, a moderate positive significant relationship was found between the DHI score and the PSQI score. CONCLUSION: Exposure to major earthquakes and aftershocks can cause sleep disorders and dizziness complaints, which may emerge as public health problems. Earthquake victims should be followed up and necessary interventions should be made early.

RESUMEN

With increasing demand for improved protein-rich food, diverse poultry birds like turkey are gaining popularity in India. However, with the rising concerns of antibiotic residues and drug resistance, safe alternatives like formic acid (FA) and thymol (TH) have attracted the attention of researchers as effective replacer of antibiotic growth promoters (AGP). This experiment investigated the effects of combinations of FA and TH on growth performance, immunity, gut microflora and jejunal microstructures in turkey. A total of 240 turkey poults were reared in 6 treatment groups for a period of 16 weeks with standard management and feeding: T1 (basal diet only); T2 (AGP); T3 (FA@2.5 ml + TH@240 mg/kg); T4 (FA@2.5 ml + TH@360 mg/kg); T5 (FA@7.5 ml + TH@240 mg/kg) and T6 (FA@7.5 ml + TH@360 mg/kg). The results revealed that T5 group had the highest final body weight and best FCR while the feed consumption across the groups was comparable. The immune status of the turkey improved (p ≤ 0.05) in treatment groups compared to control with T4 and T5 group showcasing the best CBH response, antibody titres and relative immune organ weight index. A significant improvement (p ≤ 0.05) in jejunal microstructures was observed at 16th week in T5 group over control and AGP fed group. There was significant (p ≤ 0.001) reduction in total plate and coliform counts, but a positive shift was seen in Lactobacillus population in T5 group as compared to control and AGP fed group. In conclusion, the concoction of formic acid (7.5 ml/kg) + thymol (240 mg/kg) in-feed supplement improved the performance, immune status and gut health in turkey as an efficient alternative to AGPs.

RESUMEN

BACKGROUND: Hemorrhagic enteritis, caused by Turkey Hemorrhagic Enteritis Virus (THEV), is a disease affecting turkey poults characterized by immunosuppression and bloody diarrhea. An avirulent THEV strain that retains the immunosuppressive ability is used as a live vaccine. Characterizing the splice map of THEV is an essential step that would allow studies of individual genes mediating its immunosuppressive functions. We used RNA sequencing to characterize the splice map of THEV for the first time, providing key insights into the THEV gene expression and mRNA structures. METHODS: After infecting a turkey B-cell line with the vaccine strain, samples in triplicates were collected at 4-, 12-, 24-, and 72-hours post-infection. Total RNA was extracted, and poly-A-tailed mRNA sequenced. Reads were mapped to the THEV genome after trimming and transcripts assembled with StringTie. We performed PCR of THEV cDNA, cloned the PCR products, and used Sanger sequencing to validate all identified splice junctions. RESULTS: Researchers previously annotated the THEV genome as encoding 23 open reading frames (ORFs). We identified 29 spliced transcripts from our RNA sequencing data, all containing novel exons although some exons matched some previously annotated ORFs. The three annotated splice junctions were also corroborated by our data. During validation we identified five additional unique transcripts, a subset of which were further validated by 3' rapid amplification of cDNA ends (3' RACE). Thus, we report that the genome of THEV contains 34 transcripts with the coding capacity for all annotated ORFs. However, we found six of the previously annotated ORFs to be truncated ORFs on the basis of the identification of an in-frame upstream start codon or the detection of additional coding exons. We also identified three of the annotated ORFs with longer or shorter isoforms, and seven novel unannotated ORFs that could potentially be translated; although it is beyond the scope of this manuscript to investigate whether they are translated. CONCLUSIONS: Similar to human adenoviruses, all THEV transcripts are spliced and organized into five transcription units under the control of their cognate promoters. The genes are expressed under temporal regulation and THEV also produces multiple distinctly spliced transcripts that code for the same protein. Studies of the newly identified potential proteins should be urgently performed as these proteins may have roles in THEV-induced immunosuppression. Also, knowing the splicing of THEV genes should be invaluable to future research focusing on studying THEV genes, as this will allow accurate cloning of the mRNAs.

RESUMEN

BACKGROUND AND OBJECTIVES: Crush injury, the most important trauma complication encountered in earthquake victims, occurs as a result of prolonged compression of muscle mass. Crush syndrome, resulting from crush injury, and acute kidney injury (AKI) are the most common causes of in-hospital deaths after earthquakes. The aim of this study is to convey our experience after the devastating Turkey-Syria earthquake and to identify the risk factors of crush syndrome and crush-related AKI. METHODS: Of the 1134 children admitted to the emergency department, 265 with crush injury were included the study. Demographic information, laboratory and clinical data of the patients were retrospectively analyzed. RESULTS: Mean age of the patients was 10.3 ± 4.9 years (134 females and 131 males). The median time spent under the rubble was 20 h. Crush syndrome developed in 135 (50.9%). Patients with crush syndrome were older and had higher body weight, respectively (p = 0.014, p = 0.044). Acute kidney injury was present in 157 (59.2%) patients. Thirty-two patients (12.1%) received kidney replacement therapy (KRT). The risk factors for the development of AKI Stage 3 were crush syndrome, abdominal trauma, and age. CONCLUSION: This disaster taught us the importance of establishing in advance a national emergency disaster plan. Older pediatric earthquake victims with multiple trauma and severe crush syndrome should be closely followed-up for development of AKI and, if necessary, started on dialysis. Timely access to medical care, early fluid resuscitation, and effective use of dialysis treatment are essential.

RESUMEN

PURPOSE: This study was carried out to determine the presence of Entamoeba histolytica in water sources of Nigde province in Turkey, between June and November 2021. METHODS: A total of 90 water samples were taken from 15 different water sources (drinking water, well water, spring water, wastewater and dam water) every month and the presence of E. histolytica antigens in the samples was examined by ELISA. RESULTS: The positivity for E. histolytica was determined in 7 (7.7%) of 90 samples. While no antigens were found in any of the samples in June and September, E. histolytica was positive for three samples (20%) in July, one sample (6.6%) in August and October and two samples in November (13.3%). One of 24 dam samples (4.1%), 1 of 12 wastewater samples (8.3%), 1 of 12 well samples (8.3%), and 4 of 24 fountain samples (16.6%) that examined by ELISA were found positive. On the other hand, none of the examined 18 spring samples were positive. In addition, 4 (8.8%) of 45 samples that examined in summer and 3 (6.6%) of 45 samples that examined in autumn were detected positive by using ELISA. Entamoeba histolytica positivity in samples was statistically insignificant in terms of months, water resources and seasons (P > 0.05). CONCLUSION: As a result, the presence of E. histolytica, which is an important public health problem in water sources, was determined for the first time in Nigde province of Türkiye with this study.

RESUMEN

Turkey Hemorrhagic Enteritis (THE) is an acute disease caused by a Siadenovirus that affects 4 week-aged and older turkeys, characterized by acute depression, bloody droppings, and a high mortality rate. The immunosuppressive attributes of THE can protract disease progression and create a predisposition in birds towards subsequent bacterial infectiodoralns involving Escherichia coli and Clostridium perfringens (necrotic enteritis). Turkey Hemorrhagic Enteritis Virus (THEV) predominantly affects turkeys and carries substantial economic implications for this industry. Macrophages and B lymphocytes are recognized as the predominant target cells for the virus, while the spleen is the principal site of viral replication. Infected cells have also been observed in various other tissues, including the intestines, bursa of Fabricius, cecal tonsils, thymus, liver, kidney, peripheral blood leukocytes, and lungs. The economic relevance of this disease is derived both from the high mortality rate, which can reach 60% depending on the virulence of the strain, and from subclinical disease responsible for poor performance in vaccinated animals. This review aims to provide a comprehensive overview of THE, spanning etiology, epidemiology clinical signs and gross lesions, prevention, and management.
