RESUMO
The occurrence of lesions on the tongue and the concurrence of actinobacillosis was investigated in samples consisting of totally 2,423 corpora and 947 apices linguarum of adult cattle. The investigation was made as an extended recording in connection with routine meat inspection. The diagnosis actinobacillosis is an assessment made on the gross pathological findings confirmed by consistent results of randomised samplings for histopathological and microbiological examination. The sampling was found to be representative of the mean of the phenomena investigated, and the samples were submitted to statistical analysis. Actinobacillosis was found in 2% of the lesions of the corpus as well as the apex, and the frequency on all tongues was 0.7%. These results are compared to previous findings. The importance of initial lesions for the development of actinobacilosis, and some factors predisposing for lesion infliction are discussed on the basis of the present results and literature sources. It is concluded, that there is a connection between primary lesions and actinobacillosis.
