Project description:Relative expression levels of mRNAs in chicken IEL experimentally infected with EA, EM, or ET were measured at 1 to 6 days post-infection (dpi) following primary and secondary infections. One week-old chickens were uninfected (negative control) or were orally inoculated with sporulated oocysts of EA, EM, or ET. One week later, the infected chickens were challenged with an identical inoculum of the homologous parasite. Intestinal samples were collected daily from 5 birds in a treatment group at from 1 to 6 dpi following primary and secondary infections. Cecum, duodenum, and jejunum were collected from the birds challenged with E. acervulina, E. maxima, and E. tenella, respectively. Uninfected control samples and one of the 3 infection group samples were labeled with different fluorescent dyes and hybridized simultaneously on the same slide using a reference design with a dye swap protocol. Thirty seven-condition experiment, Non-infected control vs. Primary or secondary EA, EM, or ET infected IEL at 1 to 6. Biological replicates: 2 replicates with dye-switching from each infection groups. Two replicates per array.

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.

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.

Project description:HTC avain macrophage cell line was stimulated with E. tenella, acervulina, and maxima for 0, 4, 18, and 48 hours. Total RNA was extracted, mRNA was purified, and RNA samples were directly labeled with Alexa555 or 647. The experiment was performed in loop format, so that each sample was labeled with both dyes and hybridized to two different slides. Images were acquired by the Applied Precision ArrayWoRx scanner and software and then intensity values were obtained using Softworx Tracker. Keywords: timecurse, species comparison

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
