“…The current study is the first to use a sensitive method such as real-time PCR to determine T. vaginalis prevalence in women population in Côte d'Ivoire, and compare it to swabs stain method. The low prevalence reported in this study was also found in European countries (Field et al, 2018;Hilmarsdottir et al, 2017;Trevisan et al, 2008). In a population, assessment of prevalence rate of T. vaginalis depends on the choice of diagnostic methods.…”

Trichomoniasis is a sexually transmitted disease caused by a mobile flagellate pathogenic protist protozoan of the urogenital tract, Trichomonas vaginalis. No data is available in Côte d'Ivoire about its diagnosis by molecular methods. This study aims to identify T. vaginalis by polymerase chain reaction (PCR) among women at Institut Pasteur of Côte d'Ivoire. Vaginal swabs were obtained from each woman from July to October, 2013. For T. vaginalis detection, Giemsa stain for microscopic examination and real-time PCR were performed. The PCR targeted 67 bp region of a repeated sequence of the T. vaginalis genome. A positive T. vaginalis result was defined as a cycle threshold (Ct) less than 36. The results show that of the 194 specimens tested by both Giemsa stain method and Real-time PCR, 2 were positive to Giemsa stain (1.03%) and 7 were positive in PCR assay (3.61%). Women who had multiple sexual partners in the last two months were found to be the most infected. Comparing the two methods, real-time PCR had a higher sensitivity (100%) and specificity (97.40%). This study shows that the prevalence rate of T. vaginalis infection remains low. However, using the PCR approach allows for better detecting infection than conventional staining method.

“…However, in some parts of the world, the prevalence of this parasite is considerably different e.g. Iceland (21) and Poland (22), where no positive samples were found among the participants. In those women attending nine STD clinics in the USA (23), the prevalence rate was 14.6%, in the women of reproductive age in Brazil 16% (14), in women who suffered from problems in the genitourinary system in the south of Iraq was more than 50% (24).…”

Background: Trichomonas vaginalis is one of the most important parasites transmitted through sexual contact. Therefore, it is considered a major public health problem. Best to our knowledge, there are no new reports about the prevalence of T. vaginalis in Bandar Abbas. Objectives: The present study aimed to determine the frequency of T. vaginalis in women referred to the urban and rural health centers of Bandar Abbas, Iran. In addition, other risk factors associated with this parasite were investigated. Methods: This descriptive cross-sectional study was conducted between October 2017 and June 2018. Five hundred samples obtained from vaginal discharges or fluid were examined using wet mount and culture in Diamond medium. Moreover, the demographic data and related risk factors were gathered as a questionnaire. To analyze the data, SPSS ver. 20 was used and the statistical tests of chi-square and Fisher's exact were applied. Results: In this study, T. vaginalis was detected in 13 (2.6%) out of 500 samples of the vaginal discharges or fluids in which 12 (2.4%) were detected by wet mount and 13 (2.6%) by culture method, respectively. A significant difference was observed between the incidence of the parasite and place of residence, the level of education, and abortion. Conclusions:The relatively low parasite outbreak in the studied samples is likely as a result of continuous monitoring and appropriate treatment.

“…This is mainly in agreement with the high CT prevalences and relatively high NG prevalences in many European countries (2,3). However, the prevalence of TV was surprisingly high compared to neighbouring Poland (31), and Sweden (32) and Iceland (33) where TV has been extremely rare using the same Aptima TV assay. Instead, the high TV prevalence in Ukraine correlated more with TV prevalences described in Spain, the United States and other countries outside Europe (34)(35)(36).…”

“…Instead, the high TV prevalence in Ukraine correlated more with TV prevalences described in Spain, the United States and other countries outside Europe (34)(35)(36). The reasons for this are likely multifaceted but include less frequent use of metronidazole in Ukraine (for suspected or confirmed bacterial vaginosis and/or trichomoniasis) compared to in Sweden (32) and Iceland (33), less universal access to high-quality health care, and other socioeconomic factors.…”

M. High prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae and particularly Trichomonas vaginalis diagnosed using US FDA-approved Aptima molecular tests and evaluation of conventional routine diagnostic tests in Ternopil, Ukraine. APMIS 2019; 127: 627-634.Sexually transmitted infections (STIs) remain major public health problems globally. Appropriate laboratory diagnosis of STIs is rare in Ukraine. We investigated the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) using the US FDA-approved Aptima Combo 2 and Aptima TV assays and compared the results with the conventional routine diagnostic tests (CDTs) in Ukraine. Urogenital swabs from consecutive mostly symptomatic females (n = 296) and males (n = 159) were examined. The prevalences were as follows: 10% (n = 47) of TV, 5.3% (n = 24) of CT and 1.5% (n = 7) of NG. The specificity of some CDTs was high, for example, 100% for NG culture, TV IgG ELISA, CT IgM ELISA and CT microscopy, but lower for other CDTs, that is, from 44% to 99.8%. The sensitivity of all CDTs was suboptimal, that is, 71% (n = 5) for NG microscopy, 57% (n = 4) for NG culture, 53% (n = 8) for CT IgG ELISA, 33% (n = 1) for TV IgG ELISA, 28% (n = 13) for TV microscopy, 25% (n = 1) for CT IgA ELISA, 20% (n = 3) for CT IgM ELISA and 0% (n = 0) for CT microscopy. The prevalences of particularly TV and CT were high, but substantial also for NG, in Ternopil, Ukraine. The sensitivities of all CDTs were low, and widespread implementation of validated, quality-assured and cost-effective molecular diagnostic STI tests in Ukraine is imperative.
