Mannheimia haemolytica (M. haemolytica) is a Gramnegative bacterium, which can infect humans and animals. It’s commensal as a normal flora of the nasopharynx and tonsils in cattle, sheep and goats, pneumonic pasterellosis is one of the most economically important infectious disease in goats with a worldwide prevalence. This study aimed to investigate the incidence of M. haemolytica by bacteriological and molecular characterization in goats. One hundred nasopharyngeal swabs were collected from apparently healthy farm goats, seven lung tissue specimens and five nasal mucus swabs from slaughtered goats in Baghdad. All samples were cultured on Blood and MacConkey agars. Biochemical tests and EPI20E kit were used for identification of the suspected colonies. 5(4.46%) isolates of M. haemolytica were identified phenotypically and confirmed diagnosis by polymerase chain reaction (PCR) technique using two primers 16s rRNA and 12s rRNA genes. The results of this study concluded that identification of M. haemolytica by PCR was in accordance with those of phenotypic test and use of more than primer could improve identification of isolates
