Giardia agilis: Ultrastructure of the Trophozoites in the Frog Intestine
Intestine samples of Bufo sp. tadpoles with parasitism confirmed for Giardia agilis were studied by transmission electron microscopy. The G. agilis trophozoites were long and thin. The plasma membrane was sometimes undulated and the cytoplasm, adjacent to the dorsal and ventral regions, showed numerous vacuoles. The two nuclei presented prominent nucleoli. The cytoplasm was electron-dense with ...
متن کاملChanges in intestinal fluid and mucosal immune responses to cholera toxin in Giardia muris infection and binding of cholera toxin to Giardia muris trophozoites.
The effect of Giardia muris infection on the diarrheal response and gut mucosal antibody response to cholera toxin was examined in mice. The results obtained showed that the fluid accumulation in intestinal loops exposed to cholera toxin was increased in mice infected with a low number (5 X 10(4) ) of G. muris cysts compared with the response in noninfected mice. This effect was associated with...
متن کاملOpsonization in vitro of Giardia lamblia trophozoites.
The ability of peritoneal rabbit macrophages from immunized and nonimmunized animals to phagocytose Giardia lamblia trophozoites in the presence of serum was studied and compared in an in vitro system. The rabbits which served as the source of immune serum and macrophages were injected repeatedly at multiple sites (intramuscularly, subcutaneously, and intradermally) with a mixture of G. lamblia...
متن کاملAcquired resistance to Giardia muris in X-linked immunodeficient mice.
A previous study from this laboratory (D. P. Snider, D. Skea, and B. J. Underdown, Infect. Immun. 56:2838-2842, 1988) indicated that immunodeficient mice expressing the xid gene develop prolonged infections with Giardia muris, unlike immunocompetent mice, which eliminate the intestinal protozoan parasite in 8 to 10 weeks. In this study, CBA/N (xid) and CBA/Ca mice were infected with G. muris cy...
متن کاملImmunological aspects of Giardia infections
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...
