AbstractCo - experimental infection with Eimeria tenella and Salmonella spp. was conducted in broilers. Ninty broilers at thirty days of age were divided in to three groups, 30/ group. The first group was considered as control, the second group was given orally 5x104 sporulated oocysts of E. tenella. The third group was inoculated with the same number of sporulated oocysts in addition to the inoculaton of 1.5 x 108 Salmonella microorganisum .
The clinical signs observed in these group were restricted only to the second and third group. The gross lesions in these groups showed clinical signs which were charectrized by necrosis and bleeding of cecal tissue especially the second generation of schizogony and gametes was evident in tissue section with the severity of lesion. In addition there was an inflammatory reaction with polymorphneuclear leucocyte especially among third group which was infected with Salmonella spp.
