[Characteristics of the interaction of Leptospira with the host organism in the infectious process in golden hamsters].
The comparative evaluation of the interaction of L. icterohaemorrhagiae strain P, L. canicola strain CL and L. hebdomadis strain 650 with golden hamster liver and kidney cells is presented. Three variants of the course of Leptospira infection have been distinguished: (1) the hepato-renal (icteric) variant, caused by the adhesion of leptospires to liver cells with the colonization of their surface and the disaggregation of liver-cell complexes and by the accumulation of leptospires in the kidney interstice; as a consequence, parenchymatous hepatitis and nephroso-nephritis develop, which lead to the death of animals; (2) the renal (anicteric) variant, characterized by the absence of the infective agent and lesions in the liver, by adhesion of leptospires to and their colonization of the nephrothelium of the proximal convoluted tubules of the kidneys; in this case some of the animals die because of renal insufficiency and shock, while in the surviving animals prolonged carrier state develops; (3) the intermediate variant, characterized by the initial process of leptospiral adhesion and colonization in the liver and its subsequent progress in the kidneys.
