| factors affecting the seasonal abundance of ground squirrel and wood rat fleas (siphonaptera) in san diego county, california. | abiotic and biotic factors affecting the seasonal abundance of 3 species of sylvatic fleas on their hosts were examined at 7 sites in san diego county, california. indices for oropsylla (diamanus) montana (baker) were usually highest on spermophilus beecheyi nudipes (huey) when < 18.4 degrees c (october-december), whereas those for hoplopsyllus anomalus (baker) were highest when > 18.4 degrees c (july-september). o. montana was affected most by ambient temperature (inversely for the coastal site ... | 1996 | 8840686 |
| epizootiology of tacaribe serocomplex viruses (arenaviridae) associated with neotomine rodents (cricetidae, neotominae) in southern california. | the objective of this study was to advance our knowledge of the epizootiology of bear canyon virus and other tacaribe serocomplex viruses (arenaviridae) associated with wild rodents in california. antibody (immunoglobulin g [igg]) to a tacaribe serocomplex virus was found in 145 (3.6%) of 3977 neotomine rodents (cricetidae: neotominae) captured in six counties in southern california. the majority (122 or 84.1%) of the 145 antibody-positive rodents were big-eared woodrats (neotoma macrotis) or ca ... | 2015 | 25700047 |
| parasite prevalence and community diversity in sympatric and allopatric populations of two woodrat species (sigmodontinae: neotoma) in central california. | patterns of host-parasite association may vary across the landscape in part because of host and parasite diversity, divergence, local ecology, or interactions among these factors. in central coastal california, we quantified parasite prevalence, infection intensity, and diversity in two sister species of woodrats (neotoma fuscipes and neotoma macrotis) where the species co-occur (sympatry) and where each species exists alone (allopatry). in feces from 50 adults we identified seven taxa: the prot ... | 2015 | 25574805 |
| relapsing fever group borrelia in southern california rodents. | wild rodent reservoir host species were surveyed prospectively for infection with borrelia hermsii, the causative agent of tick-borne relapsing fever in the western united states. trapping occurred during the summer of 2009-2012 at field sites surrounding big bear lake, ca, a region where human infection has been reported for many years. using quantitative polymerase chain reaction (qpcr), we tested 207 rodents from 11 species and found chipmunks (tamias spp.) and a woodrat (neotoma macrotis) in ... | 2014 | 25276933 |
| use of a chitin synthesis inhibitor to control fleas on wild rodents important in the maintenance of plague, yersinia pestis, in california. | a study was designed to test the insect development inhibitors fluazuron and lufenuron for the control of fleas on sylvatic rodents as an adjunct to the control of plague. historical data of flea burden from 15 prior years of study at chuchupate campground, ventura county, ca, were compared to six years of treatment period data to determine if fluazuron and lufenuron were effective in controlling flea densities. the insect development inhibitors, delivered systemically via a feed cube, reduced f ... | 2008 | 19263847 |
