Abstract: | The interactive effects of Eimeria tenella and Escherichia coli infection in chickens were investigated. Specific pathogen free chickens inoculated orally with E tenella and challenged four days later with E coli via the air sac showed more severe acute septicaemic lesions and subacute serositis than chickens given E coli alone. Moreover, caecal lesions induced by E tenella were more severe in chickens given both E tenella and E coli than in those given E tenella alone. In contrast, oral inoculation of E coli did not result in acute septicaemic lesions or subacute serositis and had no effect on the severity of the caecal lesions caused by E tenella. |
