Project description:Relative expression levels of mRNAs in chicken cecal epithelia experimentally infected with Eimeria tenella were measured at 4.5 days post-infection. Two weeks old chickens were uninfected (negative control) or were orally inoculated with sporulated oocysts of Eimeria tenella. Cecal epithelia samples were collected from >12 birds in infected or uninfected group at 4.5 d following infections, in which samples from 4 birds were pooled together to form a total 3 biological replicates in each group. Parasite merozoites were also collected from four infected chickens at 5 d after infections. Uninfected control samples, merozoites and infection group samples were selected for RNA extraction and hybridization on Affymetrix microarrays. We used Affymetrix GeneChip chicken genome arrays to detail the chicken cecal epithelia gene expression in the control and E. tenella-infected birds. Infected, uninfected chicken cecal epithelia and merozoites were selected for RNA extraction and hybridization with Affymetrix microarrays. Our goal was to analyze global transcriptome changes in chicken cecal mucous membranes in response to E. tenella infection in vivo. We used infected (T1,T2,T3; three biological replicates) and uninfected (Neg1, Neg2, Neg3; three biological replicates) samples to identify genes that were differentially expressed. Meanwhile, RNA and probes were also prepared from parasite merozoites (Mzt) from infected samples (Mzt) and used as an additional control in microarray hybridization.

Proteomics analysis of the second-generation merozoites of Eimeria tenella under Nitromezuril and Ethanamizuril stress

Project description:Eimeria tenella is a high pathogenic coccidian that causes avain coccidiosis. Both Nitromezuril(NZL) and Ethanamizuril(EZL) are novel triazine compounds with high anticoccidial activity, but the mechanisms of their action are still unclear. This study explored the response of E.tenella to NZL and EZL by the study of changes in protein composition of the second-generation merozoites using label free quantification proteomics.After drug treatment, the merozoites were analyzed by LC-MS/MS. The identified proteins were annotated and analyzed by Gene ontology, Kyoto Encyclopedia of Genes and Genomes pathway and Protein-protein interaction networks analysis.

Dual RNA-seq transcriptome analysis of chicken caeca infected with Eimeria tenella

Project description:In order to elucidate the infection mechanisms of Eimeria tenella and the chicken immune response, chickens were infected with Eimeria tenella strain Hougton sporozoites. Samples were taken at 0, 1, 2, 3, 4 and 10 days post-infection and mRNA sequenced. A dual-RNA seq analysis was carried out, comparing the expression of infected chickens during each sampling time point with uninfected chickens and comparing E. tenella samples during the infection with a sample of pure sporozoites. The results show a variety of response signals in the chicken, both previously known and unknown, as well as a clear role for a variety of infection-related genes in E. tenella
