Cell-mediated Immunity against Besnoitia and Toxoplasma in Specifically and Cross-immunized Hamsters and in Cultures
The capacity of hamster peritoneal cell populations to control viability and growth of Besnoitia and Toxoplasma organisms was assessed in vivo and in vitro. Immunized hamsters reduced the homologous organisms 100- to 10,000-fold over a 5-day period, but the heterologous infection increased 100- to 1,000-fold in numbers, similar as in the nonimmune controls. Passively administered antibody was i...

15 صفحه اولMelioidosis: Pathogenesis and Immunity in Mice and Hamsters
The pathogenesis of acute respiratory melioidosis mice and hamsters is described. Inhaled organisms giving rise to lesions seemed to be first engulfed by the mononuclear alveolar phagocytes, but in less than 1 day polymorphonuclear cells made their appearance. In spite of this defense reaction, the bacteria continued to multiply and their products caused focal necrosis. These foci enlarged and ...
متن کاملStudies on serological cross-reaction of Neospora caninum with Toxoplasma gondii and Hammondia heydorni.
The enzyme-linked immunosorbent assay (ELISA) was used to examine cross-reactivity of Neospora caninum with Toxoplasma gondii and Hammondia heydorni. Anti-T. gondii mouse and cat sera cross-reacted with N. caninum soluble antigen (NLA), but not with the recombinant surface antigen (NcSRS2). Anti-H. heydorni dog sera showed no cross-reactivity with either the NLA antigen or the NcSRS2. Lack of c...
متن کاملRedescription of Hammondia hammondi and its differentiation from Toxoplasma gondii.
Hammondia hammondi is a protozoan parasite that, until 1975, was misidentified as Toxoplasma gondii. Recently, the validity of H. hammondi has been questioned. In this article, the authors redescribe the parasite and its life cycle, provide accession numbers to its specimens deposited in a museum, and distinguish it structurally and biologically from T. gondii. Hammondia hammondi was found to b...
