“…In the present study, trichomoniasis was more common in the age group of 26-35 y, followed by the age group 18-25 y. This finding was consistent with other previous studies [17,33] , confirming that trichomoniasis is commonly associated with female patients at childbearing ages, since these age periods represent the period of sexual activity [34] . Sociodemographic data concerning residency, education level, and occupation did not differ between our study groups.…”

Background: Trichomoniasis is the most common curable sexually transmitted disease worldwide, suspected of increasing the risk for adverse pregnancy outcomes. Objective: In this study, we aimed to determine influence of trichomoniasis on pregnancy outcome, detect the rate of trichomoniasis during pregnancy and to identify the risk factors of trichomoniasis. Patients and Methods: Vaginal swabs were obtained from 200 pregnant females with a gestational age of 13 to 40 weeks calculated according to the last menstrual cycle. Clinical examination, vaginal discharge wet mount, Giemsa stain, and culture in modified Diamond's media were performed. Metronidazole treatment was given for all positive cases. Patients were advised to encourage their partners to receive the same treatment. Sociodemographic information was collected, and cases were divided into two groups, the study group (infected) and the control group (not infected). Pregnancy outcome (full term delivery, preterm labor, premature membrane rupture, low birth weight infants) was assessed according to the elapsed time from the first sonogram to the week of delivery. Results: Twenty-four cases were positive for T. vaginalis. Positivity was mostly detected by culture (12%) followed by wet mount microscopy and/or Giemsa staining (8.5%). Premature rupture of membrane was detected in 17/24 (70%) of trichomoniasis positive and in 29/176 (16.5%) of trichomoniasis negative cases (P=0.0001). Preterm delivery was detected in 12/24 (50%) of positive cases and 29/176 (16.5%) of negative cases (P=0.0001). Low birth weight of infants was observed in 17/24 (70%) of positive cases and in 28/176 (15.9%) of negative cases (P=0.0001). Premature membrane rupture and preterm delivery were statistically significant in positive cases with bad compliance to metronidazole treatment (P=0.044) and (P=0.004), respectively. The high rate of infection was observed in age group of 26-35 years (P=0.017). In addition, isolation of the parasite was significantly (P>0.05) recorded in pregnant women presenting with vaginal discharge and history of previous infection. Conclusion:Our results highlight the presence of preterm delivery and delivery of low birth weight infants in infected pregnant women presenting with vaginal discharge and a history of previous infection. Premature membrane rupture and preterm delivery were statistically significant in positive cases with bad compliance to metronidazole treatment. Therefore, pregnant women should be screened for trichomoniasis to reduce the incidence of preterm delivery and low birth weight.

“…In 2016, WHO estimated that the global infection rate of trichomoniasis was 0.6% in males and 5.3% in females [ 1 ]. It has been reported that more than 276.4 million people worldwide have been infected with T. vaginalis [ 28 , 29 ]. In 2013, the prevalence of trichomoniasis was estimated to be about 58 million cases, and women were twice as likely to be infected as men [ 7 ].…”

Trichomonas vaginalis (T. vaginalis) could cause trichomoniasis through sexual transmission, which was globally distributed. In this study, the prevalence and phylogenetic analyses of T. vaginalis among men in Xinxiang were conducted. From October 2018 to December 2019, a total of 634 male clinical samples were collected, including 254 samples of semen, 43 samples of prostate fluid, and 337 samples of urine. These samples were examined by nested PCR and a total of 32 (5.05%) T. vaginalis-positive samples were detected. Among these samples, the positive rates of T. vaginalis in semen, prostate fluid, and urine were 7.87% (20/254), 4.65% (2/43), and 2.97% (10/337), respectively. Three actin genes were successfully isolated and sequenced from the 32 positive DNA samples, and the analysis of the sequence and phylogenetic tree showed that the three actin gene sequences exhibited 99.7%–100% homology to the published actin gene sequence (EU076580) in NCBI, and the T. vaginalis strains in the three positive samples were identified as genotype E. Our results demonstrate a notable genotype of T. vaginalis in the male population and provide insight into the performance of these genetic markers in the molecular epidemiology of trichomoniasis. However, further studies are needed to research the association between the genotype and the pathogenicity of T. vaginalis.

“…According to updated global data, 156 million cases per year are infected by T. vaginalis, where the prevalence in women between 15-49 years old is 5.3%, while in men is 0.6% (51,52). It is known that the infection in women may be asymptomatic or have vaginal discharge, pruritus, dysuria, vaginitis, and cervicitis (53)(54)(55). Infected men are also asymptomatic, although urethritis may be shown in some cases (56).…”

Trichomonas is a common protozoan that causes a sexually transmitted disease in humans called Trichomonosis and venereal and intestinal Trichomonosis in cattle and cats, respectively. This parasite also causes avian Trichomonosis, or canker, in birds' gastrointestinal tract. Three main pathogenic species (T. vaginalis, T. fetus, and T. gallina) belonging to this genus are identified and recorded in different parts of the world. However, their presence and epidemiology are still incompletely known in other parts, particularly in T. fetus in Iraq. This review aims to update information on this disease based on an electronic search of databases to document the presence and prevalence of Trichomonas spp. in humans and some animals in Iraqi cities. The findings show that the infection by T. vaginalis and T. tenax in humans and T. gallinae in birds are identified in Iraq, recording different percentage rates. However, venereal and intestinal Trichomonosis caused by T. fetus tends to be slight or absent in cattle and cats. Venereal Trichomonosis is only found in Basra and Nineveh provinces cattle, while intestinal Trichomonosis is not recorded in Iraq yet. T. hominis is recorded in central and northern areas of Iraq. In conclusion, less or absence of the infection in cattle or cats may be ascribed to animal breed, climate, less of studies, and/or other unknown factors. Thus, epidemiological and molecular studies are needed to investigate the presence and prevalence of this disease, particularly in cattle and cats of Iraq.
