In order to elucidate the infection mechanisms of Eimeria tenella and the chicken immune response, chicken macrophage cell cultures of cell line HD-11 were infected with Eimeria tenella strain Hougton sporozoites. Samples were taken at 0, 2, 4, 12, 24, 48 and 72 hours post-infection and, purified and mRNA sequenced. A dual-RNA seq analysis was carried out, comparing the expression of infected chicken macrophages with uninfected ones at the same time points post-infection 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 different sets of SAG and MIC proteins for sporozoites and merozoites of E. tenella
Overall design: mRNA profiles of chicken macrophage cells, both uninfected and infected with Eimeria tenella sporozoites
