Conteúdo: | Attempts were made to study a possible involvement of bacteria in the periodontal lesions of "Cara inchada" in cattle (CI). Corynebacterium pyogenes could be isolated from all of 23 CI-positive bovines and from the tissue samples of 1 of 22 CI-negative controls. Bacteroides melaninogenicus occurred together with C. pyogenes in all CI-lesions and only in 1 of the CI-netative tissue samples. Bacteroides bivius was cultivated from 13 and Fusobacterium nucleatum from 9 of the 23 CI-positive, but from nome of the CI-negative animals actinomyces israelii occurred more frequently in the samples of the CI-negative than those of the CI-positive animals. The isolated bacteria were consitently susceptible in vitro to penicillin G, tetracycline and erythromycin. Repeatedintragingival injections of C. pyogenes alone and together with B. melacionogenicus into 5 calves and 2 yong sheep did not produce progressive periodontal lesions. However, 2 of calves developed distinct and 2 slight retractions of the gingiva near the sites of injections. This did not indicate a primary role of the isolated bacteria in "Cara inchada" of cattle, but could sugget some bacterial involvement in the development of the periodontal lesions.
