Bacteria associated with enzootic pneumonia in goats.
A histological and microbiological study of lung samples from 83 slaughtered goats (33 kids and 50 adults) drawn from a flock with a history of pleuropneumonia caused by mycoplasmas of the M. mycoides group was carried out. A total of 82% (27/33) of kids and 36% (18/50) of adult goats presented pulmonary lesions characteristic of enzootic pneumonia: lesions took the form of bronchointerstitial pneumonia with peribronchial and peribronchiolar proliferation of lymphocytes. Microbiological analysis confirmed a range of mycoplasma species, including Mycoplasma mycoides ssp. mycoides Large Colony (MmmlC) (3.70%; 1/27), Mycoplasma mycoides ssp. capri (Mmc) (7.40%; 2/27), Mycoplasma putrefaciens (22.2%; 6/27), Mycoplasma arginini (3.70%; 1/27) and Mycoplasma sp. (7.40%; 2/ 27), as well as Pasteurella multocida (14.8%; 4/27), associated with enzootic pneumonia lesions in younger animals, whereas Mycoplasma sp. was associated with enzootic pneumonia in adult goats (22.0%; 4/18). Cilia-associated respiratory (CAR) bacillus found by histochemical examination was associated with enzootic pneumonia in kids (25.9%; 7/27) and goats (44.4%; 8/18), being the first description of this bacterium in adult goats.
