| serologic evidence of infection with ehrlichia spp. in wild rodents (muridae: sigmodontinae) in the united states. | rodent (muridae: sigmodontinae) blood and sera collected from 14 states were tested for seroreactivity to a cultured isolate of the human granulocytic ehrlichiosis (hge) agent by using an indirect immunofluorescence assay. of the 1,240 samples tested, 136 (11%) were found to be reactive at titers of > or = 32. rodents with hge agent-specific antibodies were found in new york (23% of 491 samples; geometric mean endpoint titer [gmt] = 441), connecticut (11% of 100 samples; gmt = 481), california ( ... | 1998 | 9508298 |
| landscape models for nuclear genetic diversity and genetic structure in white-footed mice (peromyscus leucopus). | dramatic changes in the north american landscape over the last 12 000 years have shaped the genomes of the small mammals, such as the white-footed mouse (peromyscus leucopus), which currently inhabit the region. however, very recent interactions of populations with each other and the environment are expected to leave the most pronounced signature on rapidly evolving nuclear microsatellite loci. we analyzed landscape characteristics and microsatellite markers of p. leucopus populations along a tr ... | 2014 | 24448564 |
| emergence of ixodes scapularis and borrelia burgdorferi, the lyme disease vector and agent, in ohio. | lyme disease, the most common vector-borne disease in the united states, is caused by a tick-borne infection with borrelia burgdorferi. currently, ohio is considered by the centers for disease control and prevention (cdc) to be non-endemic for lyme disease. the low incidence of lyme disease in this state was largely attributed to the absence of the transmitting vector, ixodes scapularis, commonly known as the blacklegged tick. however, a tick surveillance program established by ohio department o ... | 2014 | 24926441 |
