The Pathologic and Bacteriologic Comparison of Pneumonia in Lambs
نویسنده
چکیده
The correlations between the bacteriologic agent of lamb pneumonia and its pathologic characters were investigated in this study. Pneumonia was detected in 262 (35.41%) of 740 diseased or dead lambs. Pathogenic bacteria were isolated in 114 cases (14.96% of all lamb deaths and 43.51% of all pneumonias). Lung lesions were histopathologically described as acute-catarrhal (17.56%), catarrhal-purulent (14.50%), purulent-necrotic (9.54%), fibrinous (26.72%), fibrinous-necrotic (5.73%), interstitial (18.32%), or verminous pneumonia (7.63%). In bacteriological studies, Mannheimia haemolytica (56.14%), E. coli (24.56%), and Pasteurella multocida (10.52%) were detected as important bacterial agents that caused different pneumonic lesions in lambs.
