    Bacteriological analysis were performed on 123 lungs in pulmonary cases of adherence in pig carcasses from 59 different farms at an abattoir in Rio Grande do Sul, Brazil. After classification by the Federal Inspection Service, were collected 49 samples of lungs from carcasses free for comsumption, 45 destined to consumption after heat treatment and 29 from condemned carcasses. Bacteriological examination revealed Pasteurella multocida as the most frequent bacteria isolated (61 samples) followed by Arcanobacterium pyogenes (52 samples), also occurring coinfections with these microorganisms. Capsular type A of P. multocida were prevalent (44 isolates). Other microorganisms also isolated were Actinobacillus pleuropneumoniae (4 samples), Haemophilus parasuis (2), Streptococcus suis (5), beta haemolytic Streptococcus (4), Nocardia sp (3), Aeromonas sp (1), Staphylococcus sp (1) with negative results on 20 materials. Isolates of P. multocida revealed high susceptibility to antimicrobials on gel diffusion, being only two samples resistant to oxitetracyclin and three intermediary for streptomycin, one resistant and other intermediary to trimetoprim-sulphonamide
