| serological survey of prospect hill virus infection in indigenous wild rodents in the usa. | we found serological evidence of infection with prospect hill virus, a hantaan-like virus isolated from meadow voles (microtus pennsylvanicus), in microtine and cricetid rodents trapped in maryland, west virginia, minnesota and california, usa. fluorescent antibodies were detected in sera from m. pennsylvanicus (74/277), m. californicus (39/185), clethrionomys gapperi (5/51), peromyscus maniculatus (4/22) and p. truei (1/11). sera from seropositive p. maniculatus contained neutralizing antibodie ... | 1987 | 2895510 |
| identification of an isolate of rickettsia canada from california. | a strain of rickettsia canada was recovered in 1980 an adult rabbit tick, haemaphysalis leporispalustris, taken from a black-tailed jack rabbit, lepus californicus, in mendocino county, california. in all examined biologic characteristics, this isolate, ca410, is indistinguishable from the prototype, strain 2678, isolated in ontario, canada, in 1963. these similarities include serologic and immunologic reactivity in laboratory mice and guinea pigs, cultural characteristics in vero cells, chick e ... | 1982 | 6756179 |
| serotypes of tick-borne spotted fever group rickettsiae from western california. | a rickettsial survey of ixodid ticks known to bite man was conducted in 1979 in four coastal counties of california to obtain isolates from tick species that might be involved in the transmission of spotted fever-like illnesses, and to examine serologic characteristics of the rickettsiae relative to defined members of the spotted fever group (sfg). one hundred and seventy (19.4%) of 877 ticks comprising three species were shown by hemolymph test to harbor rickettsia-like organisms. a total of 85 ... | 1981 | 6789691 |
| isla vista virus: a genetically novel hantavirus of the california vole microtus californicus. | prospect hill virus (ph) was isolated from a meadow vole (microtus pennsylvanicus) in 1982, and much of its genome has been sequenced. hantaviruses of other new world microtine rodents have not been genetically characterized. we show that another microtus species (the california vole m. californicus) from the united states is host to a genetically distinct ph-like hantavirus, isla vista virus (ilv). the nucleocapsid protein of ilv differs from that of ph by 11.1% and a portion of the g2 glycopro ... | 1995 | 8847529 |
| pneumocystosis in wild small mammals from california. | cyst forms of the opportunistic fungal parasite pneumocystis carinii were found in the lungs of 34% of the desert shrew, notiosorex crawfordi (n = 59), 13% of the ornate shrew, sorex ornatus (n = 55), 6% of the dusky-footed wood rat, neotoma fuscipes (n = 16), 2.5% of the california meadow vole, microtus californicus (n = 40), and 50% of the california pocket mouse, chaetodipus californicus (n = 2) caught from southern california between february 1998 and february 2000. cysts were not found in a ... | 2001 | 11310900 |
| anaplasma phagocytophilum infection in small mammal hosts of ixodes ticks, western united states. | a total of 2,121 small mammals in california were assessed for anaplasma phagocytophilum from 2006 through 2008. odds ratios were >1 for 4 sciurids species and dusky-footed woodrats. high seroprevalence was observed in northern sites. ten tick species were identified. heavily infested rodent species included meadow voles, woodrats, deer mice, and redwood chipmunks. | 2008 | 18598645 |
| community ecology and disease risk: lizards, squirrels, and the lyme disease spirochete in california, usa. | vector-borne zoonotic diseases are often maintained in complex transmission cycles involving multiple vertebrate hosts and their arthropod vectors. in the state of california, u.s.a., the spirochete borrelia burgdorferi, which causes lyme disease, is transmitted between vertebrate hosts by the western black-legged tick, ixodes pacificus. several mammalian species serve as reservoir hosts of the spirochete, but levels of tick infestation, reservoir competence, and borrelia-infection prevalence va ... | 2010 | 20380218 |
| effect of ectoparasite removal procedures on recapture of microtus californicus. | we tested the null hypothesis that anesthetizing meadow voles (microtus californicus) and brushing them vigorously for ectoparasites would have no effect on the later recapture of these voles. voles were trapped from 6 december 1993 to 10 january 1994 at faye slough wildlife area near eureka, humboldt county, california (usa). alternate trapped voles were anesthetized with ethyl ether and brushed vigorously for ectoparasites. there was no significant difference in the frequency of recapture nor ... | 1996 | 9359079 |
