Metabolic sequelae of experimental leptospirosis in grivet monkeys

Leptospira interrogans serovars balcanica and tarassovi both induced mild subclinical infections in grivet monkeys. The activities in serum of lactate dehydrogenase, alpha-hydroxybutyrate dehydrogenase, aspartate aminotransferase, alanine aminotransferase and creatine phosphokinase and the level of alpha 1-antichymotrypsin increased in a few days after infection. Concomitant decreases in serum iron levels were observed in some cases. These changes occurred in the absence of any observable clinical signs though there were histopathological lesions in some organs. No haematological changes or alterations in other sreum components were detected.
