Objective: To determine the rate of infection in breeder stocks. Design:
Animals: A total of 11 breeder stocks. Procedure: Pharyngeal swab samples from 11 farms, 3 flocks of healthy birds, 3 recovered flocks, 3 flocks with chronic disease and
2 infected flocks, were taken. The samples were transferred to the
laboratory in transport media.and tested on culture media. The
positive cases were identified and the p. multocida was confirmed by differential tests. Results: Pasteurella multocida was not isolated from either healthy or recovered birds. The organism was neither isolated from the pharyngeal swab samples of chronic form. In flocks, which showed
acute form, p.multocida was isolated from both the pharyngeal swabs or carcasses. Clinical implication: The results in this survey indicate that the
healthy birds are not carrier of p. multocida and the diseases spread by infected birds, rodents,water and feed.
