| a search for parelaphostrongylus andersoni in white-tailed deer from maine. | longissimus dorsi muscles from 42 white-tailed deer (odocoileus virginianus) from maine (usa) were examined for the parelaphostrongylus andersoni. no adult nematodes were found. prevalence based on the poisson approximation of a binomial distribution could have been between 0 and 9% (95% c.i.). however, based on prevalence documented elsewhere (10 to 18%), it is unlikely that p. andersoni occurs in white-tailed deer in central maine. | 1992 | 1602587 |

| parelaphostrongylus tenuis in maine moose and the possible influence of faulty baermann procedures. | efficacy of cleaning baermann apparati was evaluated to determine if larvae are retained on glassware after evaluating white-tailed deer (odocoileus virginianus) fecal samples containing parelaphostrongylus tenuis. residual p. tenuis larvae were recovered from 7 (11.7%) of 60 baermann apparati cleaned with soap and tap water. of 295 moose (alces alces) fecal samples collected in central and northern maine, only one contained protostrongylid larvae. our data do not support the hypothesis that rec ... | 1993 | 8445780 |
| deer density and the abundance of ixodes scapularis (acari: ixodidae). | the abundance of ixodes scapularis say (ixodes dammini spielman, clifford, piesman & corwin), the vector tick of the lyme disease spirochete and other human pathogens, is related to the presence of its primary reproductive stage host, white-tailed deer (odocoileus virginianus zimmerman). however, this relationship has not been quantified in terms that would guide wildlife management in areas in which the public is, or is likely to become, exposed to infected ticks. in this study, deer density an ... | 2003 | 12693846 |
| abundance of ixodes scapularis (acari: ixodidae) after the complete removal of deer from an isolated offshore island, endemic for lyme disease. | monhegan is an isolated 237-ha island lying 16 km off the coast of maine. introduced to the island in 1955, white-tailed deer, odocoileus virginianus zimmerman, reached a density of approximately 37/km2 by the mid-1990s. black-legged ticks, ixodes scapularis say, first noticed in the late 1980s, flourished thereafter. norway rats (rattus norvegicus berkenhout) on monhegan are highly infected with borrelia burgdorferi johnson, schmidt, hyde, steigerwalt, and brenner, the agent of lyme disease. by ... | 2004 | 15311475 |
| strategies for reducing the risk of lyme borreliosis in north america. | the incidence of lyme borreliosis continues to increase in the united states. in 1991, when lyme borreliosis first became a nationally reportable disease to the centers for disease control and prevention (cdc), a total of 9470 cases were reported; in contrast, by 2002 a total of 23,763 cases were reported, >2.5x the total in 1991. area-wide acaricides can be highly effective in killing nymphal ixodes scapularis, with >95% of nymphs killed in studies using cyfluthrin, deltamethrin, or carbaryl. t ... | 2006 | 16524769 |
| deer browse resistant exotic-invasive understory: an indicator of elevated human risk of exposure to ixodes scapularis (acari: ixodidae) in southern coastal maine woodlands. | we evaluated the relationships between forest understory structure and the abundance of questing adult and nymphal blacklegged ticks, ixodes scapularis say (acari: ixodidae), in three maine towns endemic for lyme disease, 2001-2003. in fragmented new england woodlands, over-abundant white-tailed deer, odocoileus virginianus zimmerman, overbrowse palatable species, allowing browse-resistant exotic-invasive species to replace native forest understory structures. we predicted there would be more ti ... | 2006 | 17162946 |
| seroprevalence of powassan virus in new england deer, 1979-2010. | powassan virus and its subtype, deer tick virus, are closely related tick-borne flaviviruses that circulate in north america. the incidence of human infection by these agents appears to have increased in recent years. to define exposure patterns among white-tailed deer, potentially useful sentinels that are frequently parasitized by ticks, we screened serum samples collected during 1979-2010 in connecticut, maine, and vermont for neutralizing antibody by using a novel recombinant deer tick virus ... | 2013 | 23568288 |
| prevalence of eastern equine encephalitis virus antibodies among white-tailed deer populations in maine. | during the fall of 2010, 332 deer serum samples were collected from 15 of the 16 (93.8%) maine counties and screened for eastern equine encephalitis virus (eeev) antibodies using plaque reduction neutralizing tests (prnts). the aim was to detect and map eeev activity in the state of maine. forty-seven of the 332 (14.2%) sera were positive for eeev antibodies, showing a much wider distribution of eeev activity in maine than previously known. the percentage of eeev antibody-positive deer sera was ... | 2015 | 25793477 |
| using wild white-tailed deer to detect eastern equine encephalitis virus activity in maine. | abstract serum from 226 free-ranging white-tailed deer (odocoileus virginianus) was screened for eastern equine encephalitis virus (eeev) antibodies using plaque reduction neutralization tests. eeev antibodies were detected in 7.1% of samples. this is the first time eeev antibodies have been detected in o. virginianus populations in the state of maine (me). the highest percentage of eeev positive sera was in somerset county (19%) in central me, and this is the first time that eeev activity has b ... | 2011 | 21736489 |
| factors affecting parelaphostrongylus tenuis in white-tailed deer (odocoileus virginianus) from maine. | white-tailed deer (odocoileus virginianus) collected in maine (usa) from november 1988 to december 1989 were examined for parelaphostrongylus tenuis. relationships of deer age class, sex, collection year, and deer density to prevalence and intensity of p. tenuis infections were analyzed. prevalence increased with deer age (p < 0.001) and interaction of deer age class and collection year (p < 0.001). prevalence did not vary by year in deer > or = 1 yr old (85%, n = 519), but was higher in fawns i ... | 1993 | 8487376 |
