Pleural adhesions in 155 young (3 to 15 months old) and 474 older sheep were examined macroscopically and by light microscopy. The pulmonary tissue under the adhesions was also examined. Two major types of adhesions were encountered, and were called type I and type II adhesions. Stages in the development and resolution of the type I adhesions were called fibrinous, early dense, dense and thin. Except for abnormalities of the blood circulatory system, the type I adhesions were similar to those in experimental models. Type II adhesions were proliferative lesions with villous projections, strands and nodules. Abnormality of the blood circulatory system also occurred in these adhesions. Most type I adhesions appeared to have developed in association-with pulmonary abscessation and pneumonia. No relationship between type II adhesions and lesions in the underlying lung was obvious.

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.
