use of a sentinel host system to study the questing behavior of ixodes spinipalpis and its role in the transmission of borrelia bissettii, human granulocytic ehrlichiosis, and babesia microti.ixodes spinipalpis maintains borrelia bissettii spirochetes in colorado in a cycle involving wood rats and deer mice. this tick has been described as nidicolous, remaining either attached to its rodent hosts or in the rodent nest. nidicolous ticks pose little risk of pathogen transmission to humans if they do not actively quest for hosts. to investigate the questing potential of i. spinipalpis, sentinel mice were placed in an area where i. spinipalpis had been commonly found on wood rats and dee ...200111693872
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 ( ...19989508298
