| prevalence of cuterebrid parasitism among woodmice in virginia. | botfly infestation was analyzed in 1319 small mammals from varied habitats and elevations in upland virginia, 1972-1974. adult cuterebra fontinella were reared from bots infesting the woodmouse (peromyscus leucopus). of 651 woodmice, 199 (30.6%) were infested at least once. the season of bot infestation extended from may through november of all years, with peak prevalence (mean 42.2%) in august. infestation in woodmice was general over a 2000 km2 study area during peak months. significantly grea ... | 1976 | 933308 |
| borrelia burgdorferi in ticks (acari: ixodidae) from coastal virginia. | ixodid ticks removed from hosts and from vegetation during march-november 1987 at sites in coastal virginia and north carolina were examined for borrelia burgdorferi. b. burgdorferi was evident in nine (22%) ixodes cookei packard removed from rice rats (oryzomys palustris), a white-footed mouse (peromyscus leucopus), and raccoons (procyon lotor); four (6%) amblyomma americanum (l.) removed from raccoons; and two (3%) dermacentor variabilis (say) removed from a raccoon and a rice rat. b. burgdorf ... | 1991 | 1941936 |

| native trichinosis in wild rodents in henrico county, virginia. | encapsulated larvae of trichinella spiralis were found in wild-trapped, microtus pennsylvanicus and sigmodon hispidus. in addition, peromyscus leucopus and mus musculus again were found infected. these mammals were trapped from a farm site in henrico county, virginia, remote from known potential sources of trichinosis. the possible zoonotic relationship between wild rodent trichinosis and swine trichinosis is discussed. | 1980 | 7001047 |
| geographic variation in peromyscus leucopus: short-day induced reproductive regression and spontaneous recrudescence. | in order to determine if intraspecific differences exist in the photoperiodic control of the reproductive cycle of white-footed mice (peromyscus leucopus), 34 male and 60 female mice from either connecticut (ct), virginia (va), or georgia (ga) laboratory stocks were exposed to either a long (16l:8d) or short (9l:15d) photoperiod for up to 27 weeks. reproductive status (testis length or the presence of a perforate vagina) of these mice was assessed every 1 to 2 weeks. after this time, the males w ... | 1982 | 7126737 |
| borrelia burgdorferi in eastern virginia: comparison between a coastal and inland locality. | in virginia, borrelia burgdorferi was more prevalent in a site along the atlantic ocean, near maryland, than in an inland site near williamsburg and yorktown. at the coastal site on assateague island, b. burgdorferi was isolated from 4.2% of 475 animals sampled, including four species of small mammals. serologic tests indicated that 25-37% of the small rodents assayed had been exposed to b. burgdorferi. immunofluorescence antibody assays specific for b. burgdorferi showed spirochete infection in ... | 1995 | 7677212 |
| parasitic arthropods of white-footed mice at mcclintic wildlife station, west virginia. | seven species of parasitic arthropods (one sucking louse, one bot, 2 fleas, one tick, and 2 mites) were recovered from 81 white-footed mice, peromyscus leucopus, live-trapped on the grounds of the mcclintic wildlife station, mason county, wv, from march through november 1990. the most commonly collected arthropods were the fleas orchopeas leucopus (89 specimens) and epitedia wenmanni (23), and the tick dermacentor variabilis (38). sex ratios for both flea species were female biased; 1.8:1.0 for ... | 1994 | 8014620 |
| host utilization and seasonal occurrence of dermacentor species (acari:ixodidae) in missouri, usa. | a total of 3,235 dermacentor variabilis (say) specimens were collected from birds, mammals, and by dragging vegetation, and 2,683 d. albipictus (packard) ticks were collected from deer from 1993 to 1996. peak seasonal occurrence of adult d. variabilis was from may through july with a precipitous decrease in august. nymphal d. variabilis populations peaked in june. peak activity of larvae was bimodal, with one activity peak during late summer (september) and a second peak in winter or early sprin ... | 2000 | 11201355 |
| comparison of the reservoir competence of medium-sized mammals and peromyscus leucopus for anaplasma phagocytophilum in connecticut. | in the northeastern united states, anaplasma phagocytophilum, the agent of human granulocytic ehrlichiosis (hge), is transmitted by the tick vector ixodes scapularis. the white-footed mouse peromyscus leucopus is a competent reservoir for this agent, but the reservoir competence of non-peromyscus hosts of i. scapularis has not been studied. here, we report data confirming reservoir competence of medium-sized mammals for a. phagocytophilum. raccoons, virginia opossums, gray squirrels, and striped ... | 2002 | 12737542 |
