RESUMEN
Six of 7 and 3 of 4 goats inoculated with live and heat-killed P. haemolytica (biotype-T), respectively, had pneumonia at necropsy. Clinically, the pneumonia was only detected in 8 of 9 goats with diseased lungs. One goat died of a fibrinous pneumonia which was associated with a profuse growth of both P. haemolytica (biotype-T) and P. multocida and a limited growth of Escherichia coli from the lungs. In the remaining 8 goats with lung lesions, the pneumonia was of the proliferative type, with only some showing the exudative feature. Five of these goats (including 3 controls) had bacteriologically sterile lung lesions, while the other 3 yielded P. haemolytica (biotype-T) and in one of them, chlamydia were also isolated. P. haemolytica (biotype-T) and P. multocida were isolated from 1 of 2 goats with normal lungs.

An enclosed swab assembly was employed to collect nasal mucus from 45 clinically normal goats. Eleven bacterial species were isolated from their nasal cavities. Pasteurella haemolytica and Pasteurella multocida were the most important isolates.
