Prevalence of Trichomonas Vaginalis in Diabetic Females
Abstract Background and Objective: Trichomonas vaginalis is a pathogenic agent known worldwide and affects about 180 million annually. We aimed to investigate the prevalence of Trichomonas vaginalis in diabetic patients referred to diabetic research center. Material and Methods: In this descriptive-analytic study, 215 women referring to the Diabetic Center in Kermanshah Province were invest...
متن کاملParasitism by virulent Treponema pallidum of host cell surfaces.
The interaction between virulent Treponema pallidum extracted from infected rabbit testes and animal cells in culture was examined. The extent of treponemal attachment to monolayers of normal rabbit testicular and HEp-2 cells was dependent upon the incubation temperature and retained motility of the spirochetes. The specific orientation of treponemes to host cell surfaces was demonstrated by da...
متن کاملTrichomonas vaginalis: current understanding of host-parasite interactions.
Trichomonas vaginalis is a sexually transmitted obligate extracellular parasite that colonizes the human urogenital tract. Despite being of critical importance to the parasite's survival relatively little is known about the mechanisms employed by T. vaginalis to establish an infection and thrive within its host. Several studies have focused on the interaction of the parasite with host cells and...
متن کاملHost plasma proteins on the surface of pathogenic Trichomonas vaginalis.
Sodium dodecyl sulfate-gel electrophoresis and fluorography and fluorography technology revealed that pathogenic Trichomonas vaginalis was able to acquire numerous loosely associated plasma proteins during incubation in normal human plasma. These proteins were readily removed by repeated washing of the parasite in phosphate-buffered saline. Plasma proteins avidly bound to the surface of T. vagi...
متن کاملTrichomonas vaginalis
We have investigated the effects of a novel neutrophil-activating factor released by Trichomonas vaginalis (TV-NAF) on neutrophil chemotaxis. TV-NAF was present in the supernatant from 107 T. vaginalis (STV) cultured in 1 ml of serum-free Hanks' balanced salt solution (HBSS) at 37°C for 30 min. With a multichamber chemotactic assay, we found that there were 112 + 15 migrated neutrophils (mean ±...
