rabies in experimentally infected bears, ursus spp., with epizootiologic notes. 19751166716
rabies surveillance in the united states during 1989.in 1989, 4,808 cases of rabies in animals other than human beings were reported to the centers for disease control, 1.8% more (4,724 to 4,808) than in 1988. eighty-eight percent (4,224/4,808) of those affected were wild animals and 12% (584/4,808) were domestic animals. cases were reported from 49 states, the district of columbia, and puerto rico; hawaii remained rabies-free. skunks (1,657) continued to be the most commonly reported rabid wild animal. for the second consecutive year, more cats ( ...19902276949
serologic survey for selected microbial pathogens of wolves in alaska, 1975-1982.serum samples were collected from 116 wolves which were captured in southcentral alaska during 1975 through 1982. antibodies to the following infectious disease agents were found: infectious canine hepatitis virus-72 of 87 (81%), canine parvovirus type 2-0 of 55 (0%) through 1979 and 10 of 32 (31%) after 1979, francisella tularensis-16 of 67 (25%), canine distemper virus-10 of 83 (12%), coxiella burnetti-5 of 95 (5%), rabies virus-1 of 88 (1%), brucella spp.-1 of 67 (1%), leptospira interrogans- ...19873029442

occurrence of rabies in a wolf population in northeastern alaska.nine alaskan wolves (canis lupus) were found dead during spring and summer 1985; five of seven animals tested for rabies virus were positive. the 1985 epizootic altered annual den use patterns by wolves in northeastern alaska, but did not appear to affect population size. we propose that rabies in arctic wolves may be more common than previously thought.19957563430
survey of fox trappers in northern alaska for rabies antibody.the purpose of this research was to determine whether trappers in northern alaska acquired immunity to rabies virus from non-bite exposures while trapping and skinning arctic foxes (alopex lagopus). in coastal alaska recurring epizootics presumably provide trappers ample opportunity for contact with rabid animals. serum neutralization analyses of blood samples collected from 26 individuals were conducted. all but three had negative rabies neutralizing antibody levels (< 0.05 i.u./ml). two of the ...19948062870
occurrence of rabies in wolves of alaska.we describe a rabies epizootic in northwest alaska (usa) during 1989 and 1990 which resulted in mortality to several different wolf (canis lupus) packs. four radio-collared wolves were confirmed to have rabies while evidence for seven others was strongly suggestive but not confirmed. the wolf population declined during the rabies epizootic; thus rabies may have been a significant limiting factor.19979131553
rabies and canine distemper in an arctic fox population in alaska.two oil field workers were attacked by a rabid arctic fox (alopex lagopus) in the prudhoe bay oil field (alaska, usa) prompting officials to reduce the local fox population. ninety-nine foxes were killed during winter 1994. we tested foxes for prevalence of rabies and canine distemper. exposure to rabies was detected in five of 99 foxes. of the five, only one fox had rabies virus in neural tissue as determined by the direct fluorescent antibody test. the other four foxes had been exposed to rabi ...200111272487
oral vaccination of captive arctic foxes with lyophilized sag2 rabies vaccine.arctic foxes (alopex lagopus) were immunized with lyophilized sag2 oral rabies vaccine. the effectiveness of this vaccine was determined by serologic response and survival to challenge by rabies virus isolated from a red fox from alaska (usa). no vaccine virus was found in saliva 1-72 hr after ingestion. at 2 wk after vaccination, all foxes had seroconverted, with rabies virus neutralizing antibody levels of 0.2-3.1 iu ml(-1). all vaccinated foxes survived to week 17 after challenge, and hippoca ...200415362836
rabies surveillance in the united states during 2006.during 2006, 49 states and puerto rico reported 6,940 cases of rabies in animals and 3 cases in humans to the cdc, representing an 8.2% increase from the 6,417 cases in animals and 1 case in a human reported in 2005. approximately 92% of the cases were in wildlife, and 8% were in domestic animals. relative contributions by the major animal groups were as follows: 2,615 raccoons (37.7%), 1,692 bats (24.4%), 1,494 skunks (21.5%), 427 foxes (6.2%), 318 cats (4.6%), 82 cattle (1.2%), and 79 dogs (1. ...200717696853
rabies surveillance in the united states during 2007.summary: during 2007, 49 states and puerto rico reported 7,258 cases of rabies in animals and 1 case in a human to the cdc, representing a 4.6% increase from the 6,940 cases in animals and 3 cases in humans reported in 2006. approximately 93% of the cases were in wildlife, and 7% were in domestic animals. relative contributions by the major animal groups were as follows: 2,659 raccoons (36.6%), 1,973 bats (27.2%), 1,478 skunks (20.4%), 489 foxes (6.7%), 274 cats (3.8%), 93 dogs (1.3%), and 57 ca ...200818795848
use of rabies postexposure prophylaxis supplied by the alaska section of epidemiology, alaska, 2002-2007.the aim of this study was to summarize the alaska experience in centralizing distribution of rabies postexposure prophylaxis (pep).200919320368
ecological niche modeling of rabies in the changing arctic of alaska.rabies is a disease of global significance including in the circumpolar arctic. in alaska enzootic rabies persist in northern and western coastal areas. only sporadic cases have occurred in areas outside of the regions considered enzootic for the virus, such as the interior of the state and urbanized regions.201728320440
population structure of two rabies hosts relative to the known distribution of rabies virus variants in alaska.for pathogens that infect multiple species, the distinction between reservoir hosts and spillover hosts is often difficult. in alaska, three variants of the arctic rabies virus exist with distinct spatial distributions. we tested the hypothesis that rabies virus variant distribution corresponds to the population structure of the primary rabies hosts in alaska, arctic foxes (vulpes lagopus) and red foxes (vulpes vulpes) to possibly distinguish reservoir and spillover hosts. we used mitochondrial ...201626661691
a conceptual model for the impact of climate change on fox rabies in alaska, 1980-2010.the direct and interactive effects of climate change on host species and infectious disease dynamics are likely to initially manifest\ at latitudinal extremes. as such, alaska represents a region in the united states for introspection on climate change and disease. rabies is enzootic among arctic foxes (vulpes lagopus) throughout the northern polar region. in alaska, arctic and red foxes (vulpes vulpes) are reservoirs for rabies, with most domestic animal and wildlife cases reported from norther ...201423452510
