Abstract: The objective of this study was to recognize, the presence of Salmonella, Brucella, Leptospira and Yersinia in slaughter swine that are apparently healthy. Samples were taken from blood, tonsils, ileum, kidney and spleen of 100 pigs that came from the States of Jalisco, Guanajuato and Sonora. For brucellosis diagnosis, card test and bacteriology from spleen were performed. For leptospirosis a micro agglutination technique was used and bacteriology from kidney. Bacteriology study was performed for Salmonella diagnosis using samples from ileum and tonsil samples were used for diagnosis of Yersinia enterocolitica. Salmonella study results were negative for all animals. Five reactors were found for Brucella by serology (5%), but no isolation was achieved. Twenty-five percent positive reactors to two serovars of Leptospira were found: Bratislava 19 animals (19%) and Panama 6 (6%) with no isolation of the bacteria. Twenty-two percent isolations of Yersinia enterocolitica biotype 1 serotypes 0:3 and 0:9 were obtained. Positive animals came from the States of Jalisco and Guanajuato. It is concluded that of the 4 diseases that were studied, the one that had more relevance was Y. enterocolitica with 22% of isolations in slaughter swine that are apparently healthy.
