The most frequent intestinal parasites that cause severe disorders in humans are Giardia lamblia and Entamoeba histolytica, which alter serum concentrations of deferent markers due to virulence factors pathogenicity. A large number people with infection asymptomatic, they can go for up a year without showing any signs or symptoms. Additionally, prolonged diarrhoea but not acute diarrhoea, these...

Amoebiasis has a worldwide distribution. It causes death, impairs the physical, mental and intellectual development thereby exerting tremendous impact on productivity of individuals especially the youngsters. This study determined the prevalence of amoebiasis in school age children in Lafia, Nasarawa State, Nigeria. One hundred and twenty (120) stool samples were examined for the cysts and/or t...

In Mexico, the Adenophyllum aurantium (L.) Strother plant is consumed as an infusion to treat intestinal diseases such as amoebiasis, which is an endemic health problem in Mexico and other countries. However, the effect of A. aurantium on Entamoeba histolytica, the causative agent of amoebiasis, is unknown. An aerial part methanolic extract (AaMeA), a root methanolic extract (AaMeR) and a root ...

Resistance to intestinal amoebiasis is mouse strain dependent. C57BL/6 (B6) mice clear Entamoeba histolytica within hours of challenge, whereas C3H and CBA strains are susceptible to infection and disease. In this study, we show using bone marrow (BM) chimeric mice that mouse strain-dependent resistance is mediated by nonhemopoietic cells; specifically, B6 BM --> CBA recipients remained suscept...

Background: Although Escherichia coli (E. coli)is a part of intestinal normal microflora of warm-blooded animals, includingpoultry, outbreaks occur in poultry raised below standard sanitation and duringthe course of respiratory or immunosuppressive diseases. Avian pathogenic E.coli (APEC) harbors several genes associated with virulence andpathogenicity. APEC strains are responsible for some dis...

A rare complication of simultaneous rupture liver abscess with caecal perforation occurs mainly in malnourished patients and carries a high mortality rate. In invasive amoebiasis, the trophozoites penetrate intestinal mucosal layer causing amoebic colitis which is carried along portal circulation to produce that more prone cases immunocompromised status. Here we report 4 ruptured associated gan...

While colonic and hepatic amoebiasis occur commonly in tropical countries, primary pulmonary amoebiasis remains a rare condition. Pulmonary involvement, when it occurs, is usually secondary to amoebic liver abscess. Primary pulmonary amoebiasis is thought to occur via haematogenous spread. We report a case of primary pulmonary amoebiasis confirmed by visualizing the trophozoites of entamoeba hi...

Delayed-type hypersensitive (DTH) response was evaluated in C3H/HeJ mice intestinally infected with Entamoeba histolytica. Infected and non-infected control mice were challenged with amoebic antigen on day 5, 10, 15, 20, 25, 30, 40, 50, and 60 post-infection. Maximum footpad swelling was observed after 24 hours of the challenge. The E. histolytica-infected mice exhibited a DTH response on day 5...
