| canine exposure to borrelia burgdorferi and prevalence of ixodes dammini (acari: ixodidae) on deer as a measure of lyme disease risk in the northeastern united states. | surveillance programs that identify areas where both the vector (ixodes dammini) and etiologic agent (borrelia burgdorferi) are present may identify the risk of lyme disease and its spread earlier and more accurately than do programs relying on any single method, particularly human case reports. hunter-killed deer (n = 1,204) from 22 counties in maryland, massachusetts, new hampshire, new york, and pennsylvania were examined in fall 1989 and all ectoparasites were identified. the following sprin ... | 1993 | 8433324 |
| correlation between tick density and pathogen endemicity, new hampshire. | to assess the endemicity of tick-borne pathogens in new hampshire, we surveyed adult tick vectors. pathogens were more prevalent in areas of high tick density, suggesting a correlation between tick establishment and pathogen endemicity. infection rates in ticks correlated with disease frequency in humans. | 2009 | 19331738 |
