Porcine enzootic pneumonia: relationship between microscopic lung and kidney lesions in Santa Catarina, Brazil = Pneumonia enzoótica suína: relação entre lesões microscópicas pulmonares e renais em Santa Catarina, Brasil
In this work the relationship between lung lesions of pigs with Enzootic Pneumonia and kidney lesions during sanitary inspection at slaughter was investigated. For this purpose sixty-nine Enzootic Pneumonia positive lung samples and sixty-nine negative ones as well as kidneys from the same pigs were post mortem examined. Microscopic examination revealed that 54.28% of the pigs (58/138) had both lesions, an association significant by Chi-square (P<0.05). The intensity of this association, by “Odds ratio” value of 0.2267 was also significant (0.09045-0.5683). Such result indicates that Porcine Enzootic Pneumonia positive pigs are more likely to develop nephritis. Although the relationship between lesions is uncertain, immunodepression caused by Porcine Enzootic Pneumonia is a probable cause of the concomitant renal disease.
