Severe respiratory signs and high mortality were the most significant clinical observations. The adult goats presented mainly respiratory symptoms and/or mastitis, whereas the young animals died showing arthritis and/or keratoconjunctivitis.The most significant lesions were found in the thoracic cavity. A focal extensive fibrino-necrotic pleuropneumonia was macroscopically seen, and the histopathological analysis confirmed a fibrinopurulent and necrotic pleuropneumonia with areas of acute pyogenic broncho-pneumonia acid fibrinous pericarditis associated with a multifocal purulent mastitis and/or a fibrinopurulent arthritis in some goats.Microbiologically, the mycoplasmas isolated grew rapidly (18-24 h), and, after 48 h, there were colonies of 1-1.5 mm diameter. These isolations were biochemically characterized as Mycoplasma mycoides spp. and showed serological characteristics corresponding to Mycoplasma mycoides subsp. mycoides Large Colony.One of the isolations, the strain 2/93, experimentally showed its pathogenicity causing acute interstitial pneumonia and arthritis when it was inoculated in 1-week-old kids.||URI:||http://hdl.handle.net/10553/47814||ISSN:||0931-1793||DOI:||10.1111/j.1439-0450.1995.tb00752.x||Source:||Journal of Veterinary Medicine, Series B[ISSN 0931-1793],v. 42, p. 587-593|
