Comparison of oocyst numbers in field sample-infected chickens. Five-day-old ROSS 308 female chickens were orally infected with 3 × 104 sporulated oocysts of 9 different field samples (A–I). Production of oocysts per group (n = 20) was obtained from the fecal samples collected from days 6 to 9 post-infection. * P < 0.05, ** P < 0.01, and ***P < 0.001 indicate significant differences compared to untreated and infected group (PC). The results represent mean ± SE values. NC, negative control; PC, untreated and infected group as a positive control; A-I, farm samples
