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...
متن کاملEvaluation of Eimeria oocyst whole antigen vaccine and the enhancive effect of probiotic on broilers
Chicken coccidiosis has great economic impacts on poultry industry. The present study was conducted to evaluate the effect of feeding probiotic (Biopellt-s) as well as Eimeria oocyst whole antigen vaccine by subcutaneous and intraperitoneal routes on body weight gain, lesion score, oocyst output, and phagocytic activity. One-day old broiler chicks were divided into seven equal groups (50 chicks...
متن کاملIdentification of common immunodominant antigens of Eimeria tenella, Eimeria acervulina and Eimeria maxima by immunoproteomic analysis
Clinical chicken coccidiosis is mostly caused by simultaneous infection of several Eimeria species, and host immunity against Eimeria is species-specific. It is urgent to identify common immunodominant antigen of Eimeria for developing multivalent anticoccidial vaccines. In this study, sporozoite proteins of Eimeria tenella, Eimeria acervulina and Eimeria maxima were analyzed by two-dimensional...
متن کاملLymphocyte Transformation Induced by Autologous Cells
Lymphocytes incubated with phytohemagglutinin or concanavalin A develop the capacity to stimulate autologous lymphocyte transformation. This is not attributable to residual mitogen contaminating the lymphoblastic cell preparation as: (a) the dissociation of mitogen from the lymphoblastic cell preparation increases the degree of stimulation observed and (b) the kinetics of lymphocyte transformat...
متن کاملEvaluation of Kadaknath Chicken for Coccidial Resistance by Oocyst Count, Lesion Scoring and Oocyst Index in Eimeria Tenella Infection
The aim of present investigation was to study the virulence of coccidiosis in Kadaknath birds, experimentally infected with E. tenella by OPG count, oocyst index and caecal lesions scoring. Sixty one-day old unsexed Kadaknath birds were randomly divided into a control, T1 and T2 groups comprising twenty chicks under each group. At d 21 of age, birds of T1 and T2 groups were individually inocula...
