Enhanced egress of intracellular Eimeria tenella sporozoites by splenic lymphocytes

Enhanced egress of intracellular Eimeria tenella sporozoites by splenic lymphocytes from coccidian-infected chickens.

Egress, which describes the mechanism that some intracellular parasites use to exit from parasitophorous vacuoles and host cells, plays a very important role in the parasite life cycle and is central to Eimeria propagation and pathogenesis. Despite the importance of egress in the intracellular parasite's life cycle, very little information is known on this process compared to other steps, e.g.,...

Excystation of Eimeria tenella sporozoites impaired by antibody recognizing gametocyte/oocyst antigens GAM22 and GAM56.

Eimeria tenella is the causative agent of coccidiosis in poultry. Infection of the chicken intestine begins with ingestion of sporulated oocysts releasing sporocysts, which in turn release invasive sporozoites. The monoclonal antibody E2E5 recognizes wall-forming body type II (WFBII) in gametocytes and the WFBII-derived inner wall of oocysts. Here we describe that this antibody also binds to th...

Suppression of Eimeria tenella Sporulation by Disinfectants

The disinfectant effects (DEs) of 10 types of chemicals, defined by their ability to destroy or inhibit oocysts and consequently prevent sporulation of Eimeria tenella field isolate, were evaluated in vitro. Correct species assignments and sample purities were confirmed by the singular internal transcribed spacer (ITS)-PCR analysis. A total of 18 treatments were performed, and the disinfection ...

Detection of Cell Mediated Immune Response in Chickens Immunized with Eimeria tenella Sporozoites

The Indian poultry sector has become a major contributor to the national economy as a result of the revolutionary and scientific approaches in avian health care management. Indian poultry industry contributes nearly Rs. 9.9 billion annually to the national economy (Mohana Subramanian et al., 2010). In India, broiler chicks are reared in deep litter system under farm condition which leads to fre...
