Specific recognition of hydatid cyst antigens by serum IgG, IgE, and IgA using western blot.
Diagnosis of hydatid disease in humans relies on the detection of specific antibodies against antigens of the metacestode from Echinococcus granulosus. The specificity and sensitivity of current immunological techniques based on specific serum IgG rely on the way antigens are purified. We used Western immunoblotting to detect specific IgG, IgE, and IgA antibodies in serum from patients with hyd...
متن کاملIdentification and localization of cyst-specific antigens of Giardia lamblia.
We induced Giardia lamblia trophozoites to encyst in vitro by exposure to conditions which are specific to the human small intestinal milieu. We now show that encystation entails the appearance of two new groups of antigens detected in Western blots by rabbit antiserum against cysts which had been purified from human feces. A heterodisperse group of lower-molecular-mass antigens (approximately ...
متن کاملStudy of resistance to Toxoplasmosis using Tachizoites surface antigens of Toxoplasma gondii in vivo
Taoxoplasma gondii is an important food-borne parasite transmitted primarily from animals to humans through meat consumption, mainly pork and lamb, as well as through oocysts shed by cats. Infection in humans can cause severe fetal malformations, ocular complications or encephalitis. Toxoplasmosis infection during pregnancy, especially in sheep, often results in abortion, representing considera...
متن کاملUsefulness of Toxoplasma gondii-specific recombinant antigens in serodiagnosis of human toxoplasmosis.
Toxoplasma gondii SAG1, GRA1, and GRA7 recombinant antigens may be regarded as tools for the detection of T. gondii immunoglobulin G antibodies in persons with chronic and acute toxoplasmosis. GRA7 is more correlated with acute toxoplasmosis. A combination of these antigens will increase the sensitivity of enzyme-linked immunosorbent assays.
متن کاملTissue-specific Cell-surface Antigens in Embryonic Cells
With the use of antisera prepared in rabbits against suspensions of live embryonic chick tissue cells, qualitative differences in cell surface antigens were demonstrated on cells from different embryonic chick tissues by immune agglutination and immunofluorescence. Unabsorbed antisera reacted with both homologous and nonhomologous cells; thorough absorption of the antisera with heterologous tis...
