Abstract: The observation that P. haemolytica is capable of producing lung lesions identical with changes seen in enzootic pneumonia has been confirmed. The macroscopic and histopathological features of such lesions produced by P. haemolytica, type A, were indistinguishable from those caused by type T. In the gross pathological picture produced by P. multocida and Staph. aureus there was more extensive involvement than in most of the P. haemolytica infections. The basic histological lesion, however, was similar in all three. No lung changes were produced with E. coli or Strep. viridans. Inoculation by intratracheal catheter of a psittacoid agent resulted in a clinical syndrome identical to that described by previous authors. The pulmonary changes also corresponded essentially to those seen by previous investigators in experimental infections and in naturally occurring ?atypical pneumonia?. A combination of the PLV agent and P. haemolytica led to the production of lesions characteristic of both agents without any clear-cut influence of one infection on the course of the other, either clinically or pathologically. Although febrile responses and lesions ascribable to P. haemolytica were more frequent in sheep pretreated with PLV agent, the numbers involved were too few and the differences too small to permit any general conclusions. |
