To clarify the infectious etiology of acute gastroenteritis in children less than 5 years of age, we conducted a 1-year prospective case-control study. Stools from150 children with diarrhea and 150 age-matched controls admitted in the hospital for illness involving system other than that of gastrointestinal tract were examined, and their parents were interviewed regarding concerning symptoms. S...

This volume contains the papers presented at the first UCLA Symposium on Molecular Biology of Host-Parasite Interactions, held in January 1983. Given the rapid growth of the study of molecular parasitology, this symposium offers a timely attempt to integrate related disciplines. While some of the works were previously published in the Journal of Cellular Biochemistry, the book organizes the man...

Case report (Dr R F Miller) A 31 year old Caucasian man was admitted to this hospital for investigation offever, progressive weight loss and cavitating lesions on his chest radiograph. The patient was a business man, he was homosexual and denied intravenous drug abuse. He smoked 30 cigarettes per day and drank 2 units of alcohol per week. His past medical history began in 1977 when he suffered ...

The SIMPLE-READ Giardia rapid assay (Medical Chemical Corporation) is a solid-phase qualitative immunochromatographic assay that detects Giardia lamblia in aqueous extracts of human fecal specimens. Testing 106 Giardia-positive and 104 Giardia-negative stool specimens yielded a sensitivity of 97.2% and a specificity of 100% for the SIMPLE-READ Giardia rapid assay.

Giardia lamblia is a protozoan parasite and the earliest branching clade of eukaryota. The Giardia life cycle alternates between an asexually replicating vegetative form and an infectious cyst form. Encystation and excystation are crucial processes for the survival and transmission of Giardia. Cysteine proteases in Giardia have been implicated in proteolytic processing events that enable the co...

Introduction: The present work aimed to assess the anti-parasitic effects of limonene (LMN) against Giardia lamblia trophozoites and cysts. Methods: Anti-Giardia activities LMN (25, 50, 100 μg/mL) were assessed G. cysts for 15-360 minutes. on apoptosis stimulation parasites determined by colorimetric protease assay. Results: more sensitive than best effect was seen at μg/mL. markedly triggered ...

Immunodeficiency, particularly antibody deficiency, predisposes to increased intensity and persistence of Giardia infections. Giardia-infected immunocompetent hosts produce serum and intestinal antibodies against Giardia trophozoites. The number of Giardia muris trophozoites, in mice with G. muris infection, is reduced by intra-duodenal administration of anti-G. muris antibody. Giardia intestin...

This work was conducted to determine the prevalence of E. coli, cryptosporidium spp., giardia, rotavirus and coronavirus agents involved in etiology diarrhea cases neonatal calf detected Burdur Mehmet Akif Ersoy University Animal Hospital Clinics other farms region between 2019-2020 years. The material study consisted 50 calves with diarrhea. Stool samples were taken from examined immunochromat...

Giardia lamblia, the protist that causes diarrhea, makes an Asn-linked-glycan (N-glycan) precursor that contains just two sugars (GlcNAc(2)) attached by a pyrophosphate linkage to a polyprenol lipid. Because the candidate cis-prenyltransferase of Giardia appears to be more similar to bacterial enzymes than to those of most eukaryotes and because Giardia is missing a candidate dolichol kinase (o...
