Leptospires in Rattus spp. on Barbados
Abstract
Among 138 Rattus norvegicus and 98 R. rattus trapped on Barbados in 1964-65 and examined for evidence of leptospiral infection, seropositivity prevalence rates were similar (34 and 30%, respectively), but isolation/dark field microscopy rates were higher in R. norvegicus (27%) than R. rattus (15%). R. norvegicus carried mainly serogroup Icterohaemorrhagiae and R. rattus mainly serogroup Autumnalis. These two serogroups cause 90% of severe human leptospirosis on the island.
