Detection of Trichomonas vaginalis by microscopy and molecular methods in women referred to health centers in Tabriz, Northwest Iran.

Trichomoniasis is a parasitic disease that affects the human reproductive and urinary systems, representing a substantial non-viral sexually transmitted infection worldwide. Given its impact on reproductive health, and the limited available information on the prevalence of Trichomonas vaginalis, this study aimed to evaluate the prevalence of T. vaginalis among women referred to health centers in Tabriz, Northwest Iran. Study was conducted on 448 suspicious women who attended to 29Bahman hospital in Tabriz, Northwest Iran, during September 2020 to September 2021. Demographic data were collected according to the study protocol. Vaginal discharges were obtained using sterile swabs, and the prevalence of T. vaginalis was determined using Papanicolauo staining and PCR method. Among the 448 cases studied, 48 (10.7%) samples were suspected as a T. vaginalis infection, while 4 (0.89%) confirmed using the PCR method. The mean age of infected individuals was 41.7 ± 9.4 years. No statistical correlation was observed between inflammation, method of contraception and infection (p = 0.8). The present study revealed a relatively low prevalence of T. vaginalis infection within the study population. Additionally, the utilization of the PCR method can be beneficial in confirming suspected samples.

Seroprevalence and risk factors of Toxoplasma gondii infection among pregnant women.

INTRODUCTION: Toxoplasma gondii is an obligate intracellular parasite affecting a broad range of warm-blooded animals, including humans. Infection acquired during pregnancy can be transmitted to the fetus and leading to serious problems such as spontaneous abortion, stillbirth, or severe mental and/or physical handicaps in the child. The purpose of this study was to investigate the seroprevalence of Toxoplasma infection and related risk factors in pregnant woman. METHODOLOGY: The study enrolled 1200 serum samples of pregnant women from February-November 2017. Then the samples were tested for the presence of anti-T. gondii antibodies (Ab) using enzyme-linked immunosorbent assay. RESULTS: Out of the 1200 samples, 381 (31.7%) and 41 (3.4%) subjects were positive for IgG and IgM Ab, respectively. Among the evaluated risk factors, the seroprevalence of Toxoplasma infection was not related to the occupation in a significant way. However significant relationship was observed with factors such as; contact with soil, cats, consumption of raw washed vegetables, and washed hands before meals. CONCLUSIONS: According to the results, more than two-thirds of pregnant women are susceptible to Toxoplasma infection, hence training health care programs should be provided to prevent infection.
