RESUMO
Objective To explore the infection situation of fungi and trichomonas and the changes of pus cell and epithelial cell counts in patients with non-bacterial vaginosis in Lanzhou .Methods The pus and epithelial cell counts of vaginal secretion samples from patients with vaginitis were detected .Fungi and trichomoniasis were checked under high power microscope ,and the samples were defined positive if fungal spores or pseudohyphae were found .Results In the 4 404 cases of patients with vaginitis ,the total rate of fungi and trichomoniasis infection was 28 .63% (1 261/4 404) .The infection rate for fungi was 25 .39% ,and for trichomonad was 3 .25% ,respectively .The dual infection rate of fungi and trichomonad was 0 .54% .Compared with ≤20 age group ,the counts of pus cells and epithelial cells in other age groups were significantly different(P<0 .05) .Conclusion Fungi were the primary in-fection etiology of non-bacterial vaginosis in Lanzhou .
RESUMO
Trichomonad species inhabit a variety of vertebrate hosts; however, their potential zoonotic transmission has not been clearly addressed, especially with regard to human infection. Twenty-one strains of trichomonads isolated from humans (5 isolates), pigs (6 isolates), rodents (6 isolates), a water buffalo (1 isolate), a cow (1 isolate), a goat (1 isolate), and a dog (1 isolate) were collected in Indonesia and molecularly characterized. The DNA sequences of the partial 18S small subunit ribosomal RNA (rRNA) gene or 5.8S rRNA gene locus with its flanking regions (internal transcribed spacer region, ITS1 and ITS2) were identified in various trichomonads; Simplicimonas sp., Hexamastix mitis, and Hypotrichomonas sp. from rodents, and Tetratrichomonas sp. and Trichomonas sp. from pigs. All of these species were not detected in humans, whereas Pentatrichomonas hominis was identified in humans, pigs, the dog, the water buffalo, the cow, and the goat. Even when using the high-resolution gene locus of the ITS regions, all P. hominis strains were genetically identical; thus zoonotic transmission between humans and these closely related mammals may be occurring in the area investigated. The detection of Simplicimonas sp. in rodents (Rattus exulans) and P. hominis in water buffalo in this study revealed newly recognized host adaptations and suggested the existence of remaining unrevealed ranges of hosts in the trichomonad species.
