Abstract/OtherAbstract:
A survey of the lungs from 4284 goats killed at a slaughterhouse in the North Island of New Zealand during the winter of 1990 revealed only ten cases of non-parasitic bronchopneumonia. However, 41% of the lungs had lesions consistent with infection by Muellerius capillaris, 33% with Dictyocaulus filaria, and 8% with both species. The prevalence of parasitic lesions increased with age. The carcasses of goats with mild to severe Dictyocaulus filaria lesions were from 0.81 to 1.52 kg lighter than those without the lesions (p<0.001). The carcasses of goats with more than ten nodular (Muellerius capillaris) lesions were 0.75 kg lighter than those without the lesions (p<0.001). Twelve sets of lungs had lesions of chronic bronchiectasis. Nematode larvae were seen in the bronchial lumina of three of them. The microscopic appearance varied from a moderate dilatation of occluded bronchi which retained an intact epithelium, to large foreign-body granulomas where the remaining bronchial outlines were barely discernible. Multiple, very discrete, fibrous pleural plaques were found on the caudal lobes in two cases. Plaques of this morphology have not been described previously in the veterinary literature. Pleural adhesions were found in 350 cases (8.2%). The relatively higher frequency of pleurisy versus non-parasitic pneumonia suggests that pneumonia in goats in the North Island of New Zealand completely resolves in most cases.
