Anti-erythrocyte IgG in hamsters with acute experimental infection by Leptospira interrogans serovar Canicola.

The aim of this study was to evaluate the behavior of erythrocyte and platelet, as immunological markers, as well as evaluate the involvement of these factors in hemolytic and hemorrhagic reactions in hamsters experimentally infected by Leptospira interrogans Serovar Canicola. Our experimental design was composed by two randomized groups: Infected Group (IG) (n = 12) and control group (CG) (n = 6). Ninety-six hours after the inoculation, the presence of immunoglobulins (IgG and IgM) and complement C3 levels, related to erythrocytes and platelets, was assessed.

Iron metabolism in hamsters experimentally infected with Leptospira interrogans serovar Pomona: influence on disease pathogenesis.

The aim of this study was to analyze the classic iron markers associated to the storage process in hamsters experimentally infected by Leptospira interrogans serovar Pomona. Four groups with six hamsters each were used; two were negative controls (C7 and C14) and two were composed by infected animals (T7 and T14). Blood samples were collected on the seventh (C7 and T7) and fourteenth days (C14 and T14) post-inoculation.
