Abstract:
We describe the geographic distribution and variation in host-pathogen specificity for Leptospira-infected small mammals collected concurrently from three Hawaiian Islands over a period of 14 years: 1990-2003. Four serogroups (Icterohaemorrhagiae, Ballum, Sejroe, and Australis) were identified from the 15,171 animals tested. Serogroup prevalence differed across host species and islands (P < 0.0001 for each), but not across years. The host associations and biogeographic patterns of Leptospira in Hawaii indicate a pathogen community shaped by ecological factors.
