Stable anaerobic resistance of Tritrichomonas foetus to metronidazole was induced in vitro by cultivation of trichomonads in the Diamond's TYM medium with metronidazole in concentrations sublethal to… Expand
Phenotypes and protein-epitope phenotypic variation among fresh isolates of Trichomonas vaginalis.
Fresh isolates of Trichomonas vaginalis were examined for reactions to a panel of five monoclonal antibodies (MAbs). Four MAbs (C20A3, DM126, DM116, and C55) were to distinct surface immunogens and… Expand

Six isolates of a strain (MRP-MT) of Trichomonas vaginalis obtained from a woman before and after unsuccessful treatment with metronidazole had an appreciably lower susceptibility to metronidazole… Expand
Degradation of collagen types I, III, IV and V by extracellular proteinases of an oral flagellate Trichomonas tenax.
Proteinases secreted by an axenic strain of Trichomonas tenax were active against native types I, III, IV and V collagens when evaluated by polyacrylamide gel electrophoresis. Degradation of all four… Expand

The ability of complement in human menstrual blood and cervical mucus to kill Trichomonas vaginalis was compared with that of complement in serum, and 95 fresh trichomonal isolates obtained from… Expand
Specific parasitism of purified vaginal epithelial cells by Trichomonas vaginalis.
Human vaginal epithelial cells (VECs) from vaginal swabs obtained from normal women or from patients with trichomoniasis were purified, and VEC parasitism by Trichomonas vaginalis was examined.… Expand
Adherence and surface properties ofTritrichomonas mobilensis, an intestinal parasite of the squirrel monkey
Adherence properties of the potentially enteropathogenicTritrichomonas mobilensis were studied in vitro. Axenically cultivated trichomonads readily attached to isolated intestinal epithelial cells… Expand
Proteinases in Trichomonas vaginalis and Tritrichomonas mobilensis are not exclusively of cysteine type.
High molecular weight proteinases of Trichomonas vaginalis (with apparent Mr values 142 and greater than 220 kDa) and Tritrichomonas mobilensis (Mr 67, 86, 104 and 120 kDa), optimally active at pH8,… Expand
Cell-associated and extracellular proteolytic activity of an oral flagellate, Trichomonas tenax.
Proteolytic activities in crude extracts and culture filtrates from Trichomonas tenax were determined using hide powder azure as substrate and the proteinase profiles in both samples were analysed in… Expand
Proteolytic activity in Tritrichomonas mobilensis.
Cell extracts of an entero-invasive protozoon of squirrel monkeys, Tritrichomonas mobilensis, contained relatively high proteolytic activity, measured on hide powder azure (HPA). Multiple proteinase… Expand
