background: giardia duodenalis is one of the most important human enteric parasites throughout the world. clinical symptoms of this parasite vary from asymptomatic infection to chronic diarrhea. still it is not clear, whether different types of pathogenesis are due to different strains of organism or to variable host factors. the purpose of this study was to investigate possible correlation of ...
Giardia lamblia (syn G. intestinalis, G. duodenalis) is the intestinal protozoan producing non-bacterial diarrhea most prevalent in the world. PCR genotype classification of Giardia in feces depends on the quality and quantity of purified DNA and the removal of a great number of inhibitors. The aim of this study was to adapt a PCR protocol to the amplification of the triosephosphate isomerase (...
We used a combined microscopy-molecular approach to determine the occurrence and identities of waterborne Giardia sp. cysts isolated from 18 separate, 10l grab samples collected from a Malaysian zoo. Microscopy revealed that 17 of 18 samples were Giardia cyst positive with concentrations ranging from 1 to 120 cysts/l. Nine (52.9%) of the 17 cyst positive samples produced amplicons of which 7 (7...
Giardia duodenalis (syn. G. lamblia, G. intestinalis) is the protozoan parasite responsible for giardiasis, the most common and widely spread intestinal parasitic disease worldwide, affecting both humans and animals. After cysts ingestion (through either contaminated food or water), Giardia excysts in the upper intestinal tract to release replicating trophozoites that are responsible for the pr...
The sensitivity and specificity of current Giardia cyst detection methods for foods are largely determined by the effectiveness of the elution, separation, and concentration methods used. The aim of these methods is to produce a final suspension with an adequate concentration of Giardia cysts for detection and a low concentration of interfering food debris. In the present study, a microfluidic ...
BACKGROUND Giardia duodenalis is prevalent in tropical settings where diverse opportunities exist for transmission between people and animals. We conducted a cross-sectional study of G. duodenalis in people, livestock, and wild primates near Kibale National Park, Uganda, where human-livestock-wildlife interaction is high due to habitat disturbance. Our goal was to infer the cross-species transm...
BACKGROUD Giardia duodenalis and Cryptosporidium spp. are enteric protozoan causing gastrointestinal illness in humans and animals. Giardiasis and cryptosporidiosis are not formally considered as neglected tropical diseases, but belong to the group of poverty-related infectious diseases that impair the development and socio-economic potential of infected individuals in developing countries. M...
