An outbreak of caprine pleuropneumonia involving about 1200 goats in the Coast and Morogoro regions of eastern Tanzania is reported. The major clinical findings were severe respiratory distress, fever, mucopurulent nasal discharge and high mortality involving all age groups and both sexes of goats. The morbidity and mortality rates were 45%-90% and 14%-50%, respectively. The principal pathological lesions were confined to the thoracic cavity and comprised hydrothorax and serofibrinous pleuropneumonia. The histopathological features consisted of a necrotizing fibrinous pleuropneumonia characterized by different degrees of vasculitis, and fibrinocellular exudation into the alveolar septae and lumina, and into interlobular septae and pleura. Mycoplasma capricolum subsp. capripneumoniae, Mycoplasma mycoides subsp. mycoides, Small Colony type Mycoplasma ovipneumoniae and Mycoplasma arginini were isolated from some of the examined goats including a case with a sequestrum which yielded Mycoplasma mycoides subsp. mycoides, Small Colony type. This work reports the first description of an outbreak of caprine pleuropneumonia in Tanzania in which M. capripneumoniae and M. mycoides subsp. mycoides, Small Colony type were concurrently isolated.
