Coccidian merozoite transcriptome analysis from Eimeria maxima in comparison to Eimeria tenella and Eimeria acervulina.
With the Eimeria spp. populations that infect chickens used as a model for coccidian biology, we aimed to survey the transcriptome of Eimeria maxima and contrast it to the 2 other Eimeria spp. for which transcriptome data are available, i.e., Eimeria tenella and Eimeria acervulina . The asexual intracellular development stage, the merozoite, was specifically examined, and we used expressed sequ...
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 کاملInduction of protective immunity against Eimeria tenella, Eimeria maxima, and Eimeria acervulina infections using dendritic cell-derived exosomes.
This study describes a novel immunization strategy against avian coccidiosis using exosomes derived from Eimeria parasite antigen (Ag)-loaded dendritic cells (DCs). Chicken intestinal DCs were isolated and pulsed in vitro with a mixture of sporozoite-extracted Ags from Eimeria tenella, E. maxima, and E. acervulina, and the cell-derived exosomes were isolated. Chickens were nonimmunized or immun...
متن کاملAnalysis of chicken cytokine and chemokine gene expression following Eimeria acervulina and Eimeria tenella infections.
The expression levels of mRNA encoding a panel of 28 chicken cytokines and chemokines were quantified in intestinal lymphocytes following Eimeria acervulina and Eimeria tenella primary and secondary infections. Compared with uninfected controls, transcripts of the pro-inflammatory cytokines IFN-alpha, IL-1beta, IL-6, and IL-17 were increased up to 2020-fold following primary infection. By contr...
متن کاملCo-infection of chickens with Eimeria praecox and Eimeria maxima does not prevent development of immunity to Eimeria maxima.
Previous studies revealed an ameliorating effect of Eimeria praecox on concurrent E. maxima infection, such that weight gain, feed conversion ratio, and intestinal lesions were nearly identical to uninfected or E. praecox-infected controls. The purpose of the present study was to determine if protective immunity against E. maxima challenge infection developed in chickens infected with both E. p...
