The present study was conducted to determine the prevalence of some bacterial infections in the captive wild animals at Giza zoo. The study was done during the period from April 2008 to December 2012. A number of 30 animal species belong to 12 Families and groups; include Canidae, Felidae, Hyaenidae, Ursidae, Rodent, Elephantidae, Otariidae, Primates, Bovidae, Camelidae, Equidae and Macropodidae were examined. The study involved 16 cases from total of 55 Canines, 4 cases from 51 Felines, one case from one 5 striped hyena. one case from one Asiatic black bear, 10 cases from 275 Rodents, two cases from 2 Indian elephants, one case from 5 South American Sea lions, 14 cases from 74 Primates, 24 cases from 200 Bovines, one case from 11 Dromedary Camels, one case from 12 Equines and three cases from 6 Macropods. This study denoted the standing of common bacterial infection problems encountered in various animal species at Giza zoo in the period of the study. The most common manifestations detected in the clinical cases were diarrhea, respiratory disorders, navil ill, suppurative wounds, suppurative otitis, purulent sinusitis, oral actinobacillosis, bloat. The most common types of diseases in the animals involved in the study based on necropsy examination were enteritis, pneumonia, septicemia, nephritis, myocarditis, endometritis,liquifactive necrosis (gangrene), gastritis and gastric ulcer. A total of 133 isolates of Gram negative and Gram positive bacteria were recovered from 78 cases of clinical cases and postmortem examination from diseased mammals belonging to 30 different animal species during the period of the study
