IgY (IgG) antibody titer in the serum and oocyst output post primary and boost immunization. (A) The OD450 value was similar between the birds immunized with EmiChIL-2 and those, immunized with the wild-type E. mitis 2 weeks after both the primary and the boost immunization (p > 0.05). (B) Mean total oocyst output per chicken of EmiChIL-2 was significantly lower than that of the wild-type E. mitis after the primary immunization (p < 0.05) 4–8 days, whereas, there was no significant difference between the EmiChIL-2 and the wild-type E. mitis-immunized birds after the boost immunization (p > 0.05) 4 to 8 days.
