Detecting Giardia: Clinical and Molecular Identification
The protozoan parasite Giardia duodenalis (syn. G. lamblia, G. intestinalis) can cause diarrhea in humans, cats, dogs and other animals. Giardia duodenalis consists of eight assemblages (A-H) that are morphologically identical but genetically distinct. Assemblages C-H are generally …

Cryptosporidium and Giardia in calves in Belgium
… a mild to profuse diarrhea. In contrast, a Giardia infection is most frequently diagnosed in calves older than 1 month and clinical symptoms comprise a chronical and intermittent diarrhea, and ill thriving. Cattle are considered as a possible reservoir for zoonotic transmission. The …

Giardia Cathepsins and Their Role in Intestinal Disease
Giardia duodenalis, a non-invasive protozoan parasite of the upper small intestine of mammals, including humans, closely associates with intestinal epithelial cells. The pathophysiology of giardiasis includes intestinal barrier dysfunction and cytoskeletal injury; however, the mechanisms or …

Giardia trophozoite-secreted proteins and their effects on intestinal epithelia
Giardia is a major cause of diarrheal disease worldwide. It is a flagellated cyst-forming enteric pathogen that inhabits the lumen of the small intestine. Two genetically distinct lineages (assemblages A and B) are of public health relevance and are often associated with water-borne outbreaks. Yet, …

Evolution of Transcription in Archaea and the Early-Diverging Eukaryote, Giardia Lamblia
… the periphery in an analysis of the genome of Giardia lamblia, highlighting the divergence of transcription systems during the early evolution of Eucarya. During the survey, the TATA-binding protein (TBP) from Giardia lamblia was observed to be highly degenerate relative to all known TBPs. …

Feline Parasitism: Parasite Prevalence and Evaluation of New Immunoassays for Giardia and Cryptosporidium
… are easier to detect than others. Diagnosing Giardia duodenalis and Cryptosporidium spp. can be difficult because cysts and oocysts shed in the feces are small, shed intermittently, and require a trained technician to consistently identify them. As a result, infections with these protozoan …

Cryptosporidium sp. and Giardia sp. in the St. Lawrence River: Impact on drinking water quality.
… the protozoan parasites Cryptosporidium sp. and Giardia sp. in raw and treated water supplies on the St. Lawrence River; (b) to find a suitable microbial indicator for the presence of Cryptosporidium sp. and Giardia sp. in raw water; (c) to measure the survival capability of Cryptosporidium …

Protein coding transcription and control of vsp gene expression in the protozoan parasite Giardia lamblia
Giardia lamblia is an early branching eukaryote and although distinctly eukaryotic in its cell and molecular biology, transcription in G. lamblia demonstrates important differences from these processes in higher eukaryotes. α-amanitin is a relatively selective inhibitor of eukaryotic RNA Polymerase …

The NADP-dependent glutamate dehydrogenase of Giardia lamblia: a study of function, gene structure, and expression
Giardia lamblia is an interesting organism in several respects. Not only is it a medically important protozoan parasite, but its location in the phylogenetic tree is at a critical and informative position. Characterization of its subcellular structure and rRNA sequences suggest that Giardia is one …

Prevalence Of, Risk Factors For, And Zoonotic Potential Of Giardia Spp. Infection In Cats Housed In An Animal Shelter
Giardia duodenalis is an intestinal protozoal parasite capable of causing both clinical and subclinical disease in a broad range of species, including humans and cats. The parasite has a ubiquitous distribution and infection occurs worldwide in nearly all mammals. Giardia infection in cats may not …

Prevalence and risk factors of GIARDIA infections in Dairy Cattle Herds in Lusaka and Chilanga Districts of Lusaka
Giardia is an intestinal protozoan parasite of mammals including humans. The objectives of the cross sectional study conducted between May 2013 and April 2014 were to estimate the prevalence of Giardia infections in dairy herds on farms in Chilanga and Lusaka districts of Lusaka Province, Zambia, …

Evaluation of a Monoclonal-based EIA for the Detection of Giardia lamblia and the Identification of the Antigen
… (EIA) tests are available for the diagnosis of giardiasis. In a time of rising health-care costs, there is a need for diagnostic tests that are rapid, specific, sensitive and inexpensive. In the first phase of this study, I developed a monoclonal-based EIA, the GIARDIA TEST, with these qualities …
