RESUMO
ABSTRACT Objective. The purpose of the present study was to test the hypothesis that cardiac alterations participate within different stages of CVL. Materials and methods. Dogs were diagnosed with CVL, were classified as follows; group I (mild disease), group II (moderate disease), group III (severe disease), group IV (very severe disease) and group V included healthy controls. Results. Ig G antibodies against Leishmaniasis in group as tested by IFAT, were deemed 1/64 to 1/16000 among infected groups. Considering the cTnI levels, there were significant differences (p=0.018) between stage IV (group IV) and healthy control group, besides between group IV and group I. Considering D-dimer levels, there was difference between healthy control group and group II, III and IV (p=0.005). Regareing NT-pro BNP levels, there were differences between healthy control group and stage III, IV, besides between stage I with stage III, IV (p=0.000). Conclusions. The results showed that levels of cTnI, Nt pro-BNP and D-dimer were higher in dogs infected with CVL in contrast to healthy dogs, in which levels of those biomarkers were below detection limits. Obtained results suggested the possibility of cTnI and NT pro-BNP as markers for cardiac damage and D-dimer as a supportive tool for a diagnosis of probable thromboembolism in dogs with CVL.
RESUMEN Objetivo. El propósito del presente estudio fue probar la hipótesis de que las alteraciones cardíacas participan en diferentes estadios de CVL. Materiales y métodos. Perros fueron diagnosticados con CVL, se clasificaron de la siguiente manera; Grupo I (enfermedad leve), grupo II (enfermedad moderada), grupo III (enfermedad grave), grupo IV (enfermedad muy grave) y grupo V controles sanos incluidos. Resultados. Los anticuerpos Ig G contra la leishmaniasis en el grupo como probado por IFAT, se consideraron 1/64 a 1/16000 entre los grupos infectados. Considerando los niveles de cTnI, hubo diferencias significativas (p=0.018). Entre el grupo IV y el grupo control sano, además entre el grupo IV y el grupo I. Considerando los niveles D-dímero, hubo diferencia entre el grupo control sano y el grupo II, III y IV (p=0.005). Teniendo en cuenta los niveles de NT-proBNP, hubo diferencia estadística entre el grupo de control sano y el estadio III, IV, además entre la etapa I con estadio III, IV (p=0.000). Conclusiones. Los resultados mostraron que los niveles de cTnI, Nt pro-BNP y D-dímero fueron mayores en perros infectados con CVL en contraste con perros sanos, en los que los niveles de estos biomarcadores estaban por debajo de los límites de detección. Los resultados obtenidos sugirieron la posibilidad de que cTnI y NT pro-BNP como marcadores de daño cardíaco y D-dímero como una herramienta de apoyo para un diagnóstico de tromboembolismo probable en perros con CVL.
RESUMO
Background: Giardia duodenalis (G. duodenalis) is an ubiquitous, flagellated intestinal protozoan with major public health significance worldwide. Limited data are available on the epidemiology of G. duodenalis in dairy cattle from Turkey. Determining the zoonotic potential of the Giardia infection requires molecular characterization. The aim of the present study was to investigate the prevalence and to molecularly characterize G. duodenalis in calves less than three months of age in Aydin, Aegean region of Turkey. Materials, Methods & Results: The study was conducted on different dairy farms in the south-western part of the Turkey, Aegean Region, Aydin. A total of 198 Holstein Friesian calves less than three months of age, of both sexes were enrolled into the study. Faecal samples from each calf were collected manually from the rectum using a disposable latex glove. The consistency of collected samples was recorded as diarrhoeic or non-diarrhoeic. Diagnosis of G. duodenalis infection was made microscopically by detection of cysts in the faecal samples. One hundred and sixteen (58.5%) of the 198 faecal samples were diarrheic. Giardia cysts were found in 27 (23.28%) of the diarrheic samples and in 8 (9.76%) of nondiarrheic samples (P < 0.05). The overall prevalence of giardiosis in calves was determined as 17.67%. The prevalence of Giardia genotypes was identified by DNA sequence analysis of the beta-giardin gene for every PCR positive sample. The beta-giardin nested PCR assay was revealed assemblage A and sub-genotype A3 was detected in all of 35 samples (100%). Discussion: The highest prevalence of Giardia infection in calves is reported at the age between 1 and 6 months, and the prevalence shows decreased rate from the age of 6 months. The present study was conducted in Aydin, a province of south-western Turkey in the Aegean Region, and the overall prevalence from a total of 198 dairy calves was 17.67%. [ ]
