Comparison of parasite replication during co-infection (CI group) of primary macrophages cell cultures and MDBK cells. Parasite replication was significantly different for both T. gondii and E. tenella in chicken macrophages compared to MDBK. a Parasite replication of T. gondii. b Parasite replication of E. tenella (mean and standard deviation, n = 3)
