In order to maintain the high production rates of poultry industry, it is necessary to prevent and control certain disease agents, which may occurred due to wild birds found near broiler houses. This study investigated the prevalence of bacteria from different organs (liver, kidney, heart, lung and content of intestine) of 76 apparently healthy resident and migratory free
living birds.The gram-negative bacteria was identified as E.coli, Proteus mirabilis, Klebsiella pneumonia, Klebsiella oxytoca , Enterobacter spp., and Citrobacter freundii, at the rate of 60.5%, 21%, 36.8%, 25%, 26.3%, and 35.5 respectively. On the other hand, a gram positive bacterium (Staphylococcus aeures) was isolated at the rate of 47.4%. Laughing dove and rock
pigeon had the highest isolation percentage of these bacteria. An examination of gastrointestinal tract revealed the presence of nematode (Ascardia galli), three species of cestoda: Hymenolepis demneota, Raillietina spp., Cotugnias spp., in resident wild birds. Ectoparasites recorded in this study were Menopon gallinae, Argas persicus.
