Heteromorphism Trichomonas vaginalis in men with chronic urogenital trichomoniasis

Abstract

Background. The morphological and functional properties of the isolates of Trichomonas vaginalis, excreted from habitats urogenital of men with chronic trichomoniasis. Methods. In 143 men with chronic urogenital trichomoniasis from scrapings of the urethra, ejaculates, and prostate secretion was allocated 205 cultures of T. vaginalis. We determined by the shape, size and structure of the nucleus and cell motility. Results. In 89.5 % of patients T. vaginalis were in only one clinical material, in the ejaculate. Trichomonas had high variability in shape, size, mobility and nuclear apparatus of the cell organization. Among the forms of the pathogen abnormal cells prevailed - mostly rounded, with a centrally located nucleus, large in size and mobility of the pendulum. Conclusions. The nature of the variability of the pathogen is determined by biotope urogenital tract of patients. So, in scrapings from the urethra was dominated pear-shaped, multi-core, small in size, with a wave-like mobility; in the ejaculate - round, single-core, with pendulum-type movement; and in prostate secret - amoeboid and oval, large, nuclear-free and immobilized forms of the parasite.
