Abstract
To determine the prevalence of Borrelia burgdorferi in British Columbian ticks, fieldwork was conducted over a 2-year period. In all, 893 ticks (Ixodes pacificus, I. angustus, I. soricis, Ixodes spp., and Dermacentor andersoni) of different life stages were retrieved from 483 small rodents (Peromyscus maniculatus, Perognathus parvus, and Reithrodontomys megalotis). B. burgdorferi DNA was detected in 5 out of 359 tick pools, and 41 out of 483 mice were serologically confirmed to have antibodies against B. burgdorferi. These results were consistent with previous studies, data from passive surveillance in British Columbia, and data from neighboring states in the Pacific Northwest, suggesting a continually low prevalence of B. burgdorferi in British Columbia ticks.
Highlights
SHORT COMMUNICATIONSSurveillance for Borrelia burgdorferi in Ixodes Ticks and Small Rodents in British Columbia*
L yme disease is one of the most common vector-borne diseases in North America and its geographic distribution is expanding in eastern Canada (Ogden et al 2009, DiukWasser et al 2012)
Lyme disease prevalence is consistently low in the Pacific Northwest (Henry et al 2011), possibly due to complex environmental factors, such as unsuitable tick habitat and the predominance of coniferous vegetation (Fig. 1a)
