Whole genome resequencing of Eimeria tenella: Beijing strain
On the 7th day after chicks were infected with Eimeria tenella Beijing strain/Guizhou strain (the peak of oocyst shedding), the chicks were dissected to collect cecal tissues. After gently rinsing off the cecal contents with PBS, the tissues on the inner wall of the cecum were scraped, digested with 1.5% trypsin, and then the coccidian oocysts were recovered and extracted.
