RESUMEN

BACKGROUND: This study assesses the prevalence of sexually transmitted infections (STIs) in first time visitors to the STIs clinic in Hangzhou, China, considering different genders, ages and symptoms. And also explores howthe COVID-19 pandemic has affected on STIs. METHODS: From 2019 to 2023, 27,283 first time visitors were tested for nine distinct STIs, including Human Papillomavirus (HPV), Human Immunodeficiency Virus (HIV), syphilis, Herpes Simplex Virus type 2 (HSV-2), Ureaplasma urealyticum (UU), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), and vaginal Candida. RESULTS: Symptomatic male and female visitors showed overall STI-positive rates of 39.27% and 59.20%, respectively(p < .001). The top three pathogens in both genders were HPV (47.56% and 56.71%), UU (29.21% and 56.47%), and HSV-2 (22.41% and 52.94%). Among asymptomatic visitors, the total STI-positive rate was 36.63% in males and 52.03% in females. Age-stratified analysis revealed higher STI rates in visitors ≤ 20 or >50 years, regardless of gender and symptoms. During the COVID-19 pandemic, symptomatic visitors showed lower positive rates for HPV, HIV, syphilis, and HSV-2, while Candida, UU, CT, NG, and multiple infections increased. Among asymptomatic visitors, HPV had the lowest positive rate, while NG and multiple infections increased during the pandemic. CONCLUSION: STI prevalence is notably high, particularly in those aged ≤ 20 and >50 years. It emphasizes the need for enhanced health education, condom use, and vaccination. The COVID-19 pandemic impacting STIs through varied factors, such as reduced sexual activity and clinical service interruption.

RESUMEN

Sexually transmitted diseases (STDs) are a global concern because approximately 1 million new cases emerge daily. Most STDs are curable, but if left untreated, they can cause severe long-term health implications, including infertility and even death. Therefore, a test enabling rapid and accurate screening and genotyping of STD pathogens is highly awaited. Herein, we present the development of the DNA-based 6STD Genotyping 9G Membrane test, a lateral flow strip membrane assay, for the detection and genotyping of six STD pathogens, including Trichomonas vaginalis, Ureaplasma urealyticum, Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma hominis, and Mycoplasma genitalium. Here, we developed a multiplex PCR primer set that allows PCR amplification of genomic materials for these six STD pathogens. We also developed the six ssDNA probes that allow highly efficient detection of the six STD pathogens. The 6STD Genotyping 9G Membrane test lets us obtain the final detection and genotyping results in less than 30 m after PCR at 25 °C. The accuracy of the 6STD Genotyping 9G membrane test in STD genotyping was confirmed by its 100% concordance with the sequencing results of 120 clinical samples. Therefore, the 6STD Genotyping 9G Membrane test emerges as a promising diagnostic tool for precise STD genotyping, facilitating informed decision-making in clinical practice.

RESUMEN

Objective To analysis the infective case of Ureaplasma urealyticum(Uu)in women pregnancy system,in order to get evidence from medicine sensitive test in UU infection case.Method Use fluorescent quantitative PCR(FQ-PCR)to detect,then provide the medicine according UU-DNA value.After half month,apply the pills the patients stop medicine for 10 days to examine culture and sensitivity test.The positive patients is applied the medicine for half month,examine the UU-DNA after stopping medicine 10 days.Results After one treatment course,51.6% patients turn into negative in culture test.48.4% positive patients turn into negative after one medicine treatment course according to medicine sensitive result.Conclusion The FQ-PCR technique with culture and sensitivity test detect and treat infective case of UU combine is useful to clinical practice.

RESUMEN

OBJECTIVE To investigate the infection status and drug resistance of Mycoplasma strains isolated from genitourinary tract. METHODS The IST kit produced by Bio-Merieux was used to culture the Mycoplasma strains and to do drug susceptibility test. RESULTS The Mycoplasma infection ratio was 41.0%,with Ureaplasma urealyticum(Uu) 71.9%,Mycoplasma hominis(Mh) 2.3%,and mixed infection 25.8%,respectively.The drug susceptibility test showed that drug resistance ratios were as follows: to erythromycin 58.7%,ciprofloxacin 50.0%,ofloxacin 41.3%,pristinamycin 3.3%,josamycin 5.4% and doxycycline 7.6%. CONCLUSIONS Mycoplasma infection in genitourinary tract is mainly due to Uu infection.We should rationally choose and use antibiotics according to the drug susceptibility,and josamycin is very effective.

RESUMEN

OBJECTIVE To investigate the infection status and drug resistance of Ureaplasma urealyticum (Uu) and Mycoplasma hominis (Mh) isolated from female genitourinary tract. METHODS The specimens of 1890 cases were collected from Jan 2003 to Dec 2006. The results of mycoplasma cultivation and susceptibility test were analyzed retrospectively. RESULTS Among 1890 cases, there were 756 cases with positive mycoplasma cultivation. Positive rate was 40.0%. Positive rate was the highest at the age of 21 to 40. Among 11 commonly used antibiotics, sensitivity of tetracyclines was the highest,followed by macrolides. Four quinolones all showed the higher resistance. CONCLUSIONS The resistance of commonly used antibiotics in mycoplasma isolated from female genitourinary tract is greatly severe.We should think highly of it.

RESUMEN

OBJECTIVE To investigate the infection status and drug resistance of mycoplasma and chlamydia isolated from female genitourinary tract in order to provide reference for doctors′ reasonable use of medicine.METHODS The IST2 kit produced by Bio-Merieux was used to culture the mycoplasma strains and to do drug susceptibility test.The VEDALAB kit was used to detect chlamydia.RESULTS Among 376 suspected patients with nongonococcal urethritis(NGU),the number of the patients infected by Ureaplasma urealyticum(Uu),mixed strains of Uu and Mycoplasma hominis(Mh),and Chlamydia trachomatis(Ct) were 216,35 and 125,respectively.The positive rate was 57.4%,9.3% and 33.3%,respctively.The drug susceptibility test showed that drug resistance rates of the other six antibiotics in mixed infection of Uu and Mh were higher than that in simple infection of Uu except for josamycin,ofloxacin and doxycycline.The sensitivity of doxycycline,josamycin and platenomycin in mycoplasma was the most highest.CONCLUSIONS Infection in female genitourinary tract is mainly due to Uu.We should reasonably choose and use antibiotics according to drug susceptibility.
