Abstract
The mouse disease model has the advantage of a broad array of immunological and genetic tools
available for basic research. Some studies on transgenic and/or mutant mouse strains as models
for experimental leptospirosis have been reported; however, the wider use of such models is
hampered by a poor understanding of the outcome of experimental leptospiral infection among the
different mouse strains available. Here, the outcome of infection by a virulent strain of Leptospira
interrogans serogroup Icterohaemorrhagiae strain Cop was studied in four commonly used wildtype
mouse strains: A, CBA, BALB/c and C57BL/6. The end points evaluated in this study were
survival, presence of kidney lesions, leptospiral load in kidney samples, microscopic agglutination
test titre and anti-leptospiral IgG antibody levels. As expected, none of the mouse strains were
susceptible to lethal leptospirosis. However, these strains developed specific pathologies
associated with sublethal leptospirosis. The A and C57BL/6 strains exhibited a high leptospiral
load in kidney samples and the CBA and C57BL/6 strains developed severe inflammatory lesions,
whilst the BALB/c strain proved to be the most resistant to subclinical leptospirosis
