Oocysts excretion after vaccination and challenge infection in chickens. Two-week-old AA broiler chickens (n = 6) were vaccinated with 1000 Emi.chFc, Emi.HA1 or WT oocysts or PBS and challenged with 4 × 105 WT oocysts two weeks after vaccination. Feces from each group were collected 5–8 days post-vaccination and challenge. Oocysts shedding per gram of feces was determined using a McMaster egg counting chamber. The data was pooled of four independent experiments with similar results and were expressed as the mean ± SD
