ectoparasite diversity and exposure to vector-borne disease agents in wild rodents in central coastal california.a survey of wild rodents was performed in the morro bay area of central coastal california to determine serological and polymerase chain reaction (pcr) prevalence of anaplasma phagocytophilum dumler, barbet, bekker, dasch, palmer, ray, rikihisa, and rurangirwa, borrelia burgdorferi johnson, schmidt, hyde, steigerwalt, and brenner, francisella tularensis mccoy, and yersinia pestis yersin; to describe the ectoparasitic fauna on important vector-borne disease hosts; and to determine whether pathoge ...200717427705
population dynamics of adult fleas (siphonaptera) on hosts and in nests of the california vole.microtus californicus (peale, 1848) were live trapped or retrapped 887 times, and fleas were collected over a 2.5-yr period in the san francisco watershed and wildlife refuge. also, 179 m. californicus nests were collected monthly with observations to identify the environment of fleas. the ratio of the mean number of fleas per nest to the mean number collected on voles was 4.7:1 for malaraeus telchinus (rothschild, 1905), 13:1 for hystrichopsylla occidentalis linsdalei holland, 1957,9:1 for atyp ...200212495178
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
