RESUMO
Concurrent infection with Actinobacillus lignieresii and Mycobacterium farcinogenes was detected in slaughtered cattle. The lesions were confined to the retropharyngeal, mandibular and parotid lymph nodes. The actinobacillus granulomas were seen either inside the caseous lesions or between the caseous part and the epithelioid zone of bovine farcy granuloma. In concomitant infections, actinobacillosis was always in the early active phase, whereas in actinobacillosis alone, active as well as healed stages were encountered.

Fasciola gigantica infection in sheep produced liver and lung lesions characterized by damage to blood vessels and parenchymal necrosis. In the lungs, the lesions were those of parasitic bronchopneumonia. The damage to the liver and lung tissues was accompanied by increased activity in serum of AST after 2 weeks, GD and SD after 4 to 5 weeks and GGT and 5'-NT from 8 weeks onwards. Bilirubin concentration was not affected.
