This study aimed to determine the etiology of bacterial pneumonia in goats. Of 200 pneumonic lesions, 51% (102/200) yielded different bacterial isolates. Mannheimia (Pasteurella) haemolytica was predominant isolates (83.3%; 85/102), followed by Corynebacterium pseudotuberculosis (6.9%; 7/102) and α-haemolytic Streptococci (4.9%; 5/102). Pasteurella multocida, Staphylococcus hyicus, S. caseolyticus, S. saccharolyticus and Actiomyces (Corynebacterium) pyogenes were represented 0.98% (1/102) for each one. The overall isolates of M. haemolytica were comprised of M. haemolytica biotype A (90.6%; 77/85) and M. haemolytica biotype T (9.4%; 8/85). The study clearly pointed that M. haemolytica biotype A was the main etiological agent of pneumonia, and highlighted the presence of C. pseudotuberculosis and Staphylococcus spp., in particular, within the etiological agents of the disease.
