The aim: to study the prevalence of protozoal infestations in cases of acute inflammatory exacerbations in genitourinary clinic.

Materials and methods. The method of polymerase chain reaction was used to examine 158 subjects with chronic inflammation of the genitourinary system exacerbations.

Results. Infestation of the genitourinary system was identified in 72 patients (45.6 %). Trichomonas infestation was identified in 63 (87.5 %) of them. Trichomonas vaginalis was identified in 1 (1.4 %) subject. Other Trichomonas species – in 62 (86.1 %) subjects. 12 (16.7 %) had Trichomonas tenax, and 50 (69.4 %) – Pentatrichomonas hominisGiardia lamblia was identified in 9 patients – i.e. in 12.5 % individuals with infestation of the genitourinary system, or in 5.7 % among subjects examined for STIs in this study.

Conclusions: High level of Trichomonas infestation of the genitourinary system was identified in subjects with of chronic inflammatory exacerbations of the genitourinary system. In most cases, infestations were caused by Trichomonas species other than Trichomonas vaginalis, as well as by Giardia lamblia. An assumption about a certain role of these pathogens in the onset or further course of inflammatory diseases of the genitourinary system was made.
