A preliminary investigation of microsatellite-based genotyping in Trichomonas vaginalis.

The genetic epidemiology of Trichomonas vaginalis is poorly understood at present. The recent release of the organism's genome sequence opens the way to investigation of polymorphic markers allowing strain identification. We here report a preliminary analysis of microsatellite loci in T.

Bioinformatic analysis of Entamoeba histolytica SINE1 elements.

Background: Invasive amoebiasis, caused by infection with the human parasite Entamoeba histolytica remains a major cause of morbidity and mortality in some less-developed countries. Genetically E. histolytica exhibits a number of unusual features including having approximately 20% of its genome comprised of repetitive elements.

SINE elements of Entamoeba dispar.

Entamoeba histolytica and E. dispar are closely related protozoan parasites; the former causes clinical amoebiasis in humans while the latter appears to be non-pathogenic. The molecular biology of E.

Progress in research on Entamoeba histolytica pathogenesis.

Entamoeba histolytica is a protozoan parasite of humans that causes 40,000-100,000 deaths annually. Clinical amoebiasis results from the spread of the normally luminal parasite into the colon wall and beyond; the key development in understanding this complex multistage process has been the publication of the E. histolytica genome, from which has come an explosion in the use of microarrays to examine changes in gene expression that result from changes in growth conditions.

A bioinformatic analysis of the RAB genes of Trypanosoma brucei.

RAB proteins are small GTPases with vital roles in eukaryotic intracellular transport; orthologous RABs appear to fulfil similar functions in diverse organisms. Trypanosoma brucei spp., the causative organisms of Old World trypanosomiasis of humans and domestic animals, have extremely effective endocytic and exocytic mechanisms that are likely to be involved in maintenance of infection, making study of these systems of importance.

The genome of the protist parasite Entamoeba histolytica.

Entamoeba histolytica is an intestinal parasite and the causative agent of amoebiasis, which is a significant source of morbidity and mortality in developing countries. Here we present the genome of E. histolytica, which reveals a variety of metabolic adaptations shared with two other amitochondrial protist pathogens: Giardia lamblia and Trichomonas vaginalis.

Nontranslated polyadenylated RNAs from Entamoeba histolytica.

Protozoan parasites display a range of unusual molecular mechanisms that could be helpful for their survival in Nature. Among these parasites, Entamoeba histolytica is one of the most prevalent in developing countries such as India. Entamoeba histolytica produces at least four different unusual transcripts, IE, Tr, ehapt1 and UEE1, that are polyadenylated, but do not have significant open reading frames.

Differentiation of entamoeba histolytica/entamoeba dispar by PCR and their correlation with humoral and cellular immunity in individuals with clinical variants of amoebiasis.

To correlate a particular state of immunity with Entamoeba spp., we used colorimetric PCR to differentiate E. histolytica from E.
