Is Trichomonas Hominis Pathogenic?

چکیده
undulans of Castellani was really allied to this species. There is no doubt that Lccschia undulans is nothing but a dying Trichomonas in its preliminary stage before rounding up. When a Trichomonas loses its active motility, it emits a finger-like protrusion in front and passes it on one side towards the back. This protrusion is then withdrawn near its back and is again emitted in the front. The figure of Lccschia undulans, given on p. 319 of Castellani and Chalmer's " Manual of Tropical Medicine," shows an undulating membrane, and there is no doubt that

Mycoplasma hominis and Trichomonas vaginalis: a unique case of symbiotic relationship between two obligate human parasites.
Mollicutes are the smallest and simplest self-replicating microorganisms. Despite the minimal genome and apparent lack of complexity, mycoplasmas show a high degree of adaptation to the most diverse environments. Mycoplasma hominis is a human sexually transmitted mycoplasma which is able to establish a biological association with Trichomonas vaginalis, a pathogenic flagellated protist. M. homin...
متن کاملSymbiotic Association with Mycoplasma hominis Can Influence Growth Rate, ATP Production, Cytolysis and Inflammatory Response of Trichomonas vaginalis
The symbiosis between the parasitic protist Trichomonas vaginalis and the opportunistic bacterium Mycoplasma hominis is the only one currently described involving two obligate human mucosal symbionts with pathogenic capabilities that can cause independent diseases in the same anatomical site: the lower urogenital tract. Although several aspects of this intriguing microbial partnership have been...
متن کاملThe Cultivation of Trichomonas of the Human Mouth (tetratrichomonas Hominis)
Trichomonades from the mouth were studied by Steinberg who proposed to group them into three distinct types; namely, Trichomonas elongata, Trichomonas caudata, and Trichomonas flagellata. Doflein (3) regards them as probably identical with Trichomonas hominis. Opinions differ as to whether or not Trichomonas vaginalis Donné and Trichomonas hominis Grassi are the same species. Lynch, for instanc...
متن کاملPreservation of Trichomonas vaginalis in liquid nitrogen.
In recent years some attention has been focused on the low temperature storage of various protozoa. The purpose of this work was to confirm that Trichomonas vaginalis can be preserved for several months at a temperature of -196°C. in liquid nitrogen. Weinman and McAllister (1947), who successfully preserved a number of pathogenic protozoa, failed to preserve T. vaginalis, and only a proportion ...
متن کاملLack of evidence for the involvement of rectal and oral trichomonads in the aetiology of vaginal trichomoniasis in Ghana.
OBJECTIVE To investigate the possible involvement of human trichomonads (Pentatrichomonas hominis and Trichomonas tenax) other than Trichomonas vaginalis in the aetiology of vaginal trichomoniasis. METHODS Vaginal swabs taken from women attending antenatal clinics were tested for Trichomonas vaginalis by traditional assays (wet-mount microscopy and InPouch culture) and nucleic acid amplificat...
