Giardia lamblia is a protozoan that causes diarrheal diseases in humans. Cytoskeletal structures of Giardia trophozoites must be finely reorganized during cell division. To identify Giardia proteins which interact with microtubules (MTs), Giardia lysates were incubated with in vitro-polymerized MTs and then precipitated by ultracentifugation. A hypothetical protein (GL50803_8405) was identified...

background : giardia lamblia and helicobacter pylori are two flagellate microorganisms that grow in duodenum and stom­ach. the aim of this study was to evaluate the prevalence of them in patients with dyspepsia and other gi disorders. methods: in this cross-sectional study, co-infection of above-mentioned agents was investigated in a group of 130 patients [me­dian age of 40 yr (range=11-79) inc...

giardia lamblia is one of the most common intestinal protozoan parasites infecting human in the world. the goal of this study was searching for in-vitro effect of folic acid and cobalamin on adhesion and growth of g. lamblia as two important mechanisms in the pathogenesis in tyi-s-33 medium. g. lamblia trophozoites were obtained by in- vitro excystation procedure. three groups of giardia tropho...

Giardia lamblia cysts obtained from human symptomatic and asymptomatic donors were excysted in vitro. Excystation averaged 87% for cysts from symptomatic donors and 70% for cysts from asymptomatic donors.

Giardia lamblia is a frequent pathogen in persistent diarrhoea. Both humoral and cellular immune responses are important in clearing the parasite and providing immunity. A rapid sensitive and specific serological test like dot ELISA could be useful for early detection of Giardia specific serum antibodies for routine diagnosis. This study reports the use of dot ELISA for the detection of Giardia...

The object of this study was to determine the importance of domestic cats in the epidemiology of human giardiasis. Of six laboratory-reared cats inoculated with cultured Giardia lamblia trophozoites from humans, only one showed the presence of cysts in the feces, and cysts were found on only 1 of the 80 days of observation. In a second experiment, eight cats were inoculated with G. lamblia cyst...
