rabies in insectivorous bats of western canada, 1979 to 1983.a total of 1,745, 362, and 536 bats collected in alberta, british columbia, and saskatchewan, respectively, was tested for rabies virus between 1979 and 1983. only one (0.1%) of 769 bats collected at random from buildings was infected with rabies virus in contrast to 95 (5%) of 1,874 symptomatic, rabies-suspect bats submitted for testing. the pattern of infection in the rabies-suspect bats was similar in alberta and saskatchewan, but differed in british columbia. rabies was diagnosed in four spe ...19863735577
bat rabies in canada 1963-1967.six hundred and twenty-eight insectivorous bats originating from seven provinces were submitted to this institute for rabies diagnosis between august 1, 1963 and december 31, 1967. brain tissue was examined by the fluorescent antibody technique and the mouse infectivity test was carried out with brain, salivary gland, interscapular adipose tissue and kidney samples. rabies virus was detected in 44 bats, 29 of which were from ontario, 12 from british columbia and three from manitoba. most of the ...19694242773
transmission of a street rabies virus strain (r-174) from the cave bat (myotis lucifugus) to the tick (ornithodoros) by blood feeding: a preliminary report. 195613277316
studies on the pathogenesis of rabies in insectivorous bats. i. role of brown adipose tissue.studies on the pathogenesis of rabies in two species of experimentally infected insectivorous chiroptera, the mexican free-tailed bat (tadarida mexicana), a quasi hibernator, and the little brown bat (myotis lucifugus), a deep hibernator, provided evidence that brown adipose tissue may serve as an extraneural site for storage and multiplication of rabies virus. although the mexican free-tailed bat proved to be relatively insusceptible to experimental rabies infection, virus was demonstrated in t ...195913835624
transmission of a strain of rabies virus to the large brown bat (eptesicus fuscus) and to the cave bat (myotis lucifugus). 195114849156
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
studies on the pathogenesis of rabies in insectivorous bats : ii. influence of environmental temperature.studies on the influence of environmental temperature on the pathogenesis of rabies in two species of experimentally infected chiroptera, the mexican free-tailed bat (tadarida mexicana) and the little brown bat (myotis lucifugus), provided evidence that little or no viral multiplication occurs in the inactive host during experimentally induced hibernation. when inoculated animals are wakened from hibernation by transfer to a warm room, virus previously in "cold storage" multiplies, reaching dete ...196019867178
overwintering of rabies virus in silver haired bats (lasionycteris noctivagans).silver-haired bats, (lasionycteris noctivagans) are semi-colonial, migratory tree bats that have infrequent contact with humans. despite the species rarity, the l. noctivagans rabies variant is the most commonly reported rabies virus variant (rabv) in domestically acquired human rabies cases in the us. unlike big brown bats (eptesicus fuscus) and little brown bats (myotis lucifugus), l. noctivagans are not considered true hibernators. it is unknown if rabv can overwinter in hibernating l. noctiv ...201627195489
susceptibility and pathogenesis of little brown bats (myotis lucifugus) to heterologous and homologous rabies viruses.rabies virus (rabv) maintenance in bats is not well understood. big brown bats (eptesicus fuscus), little brown bats (myotis lucifugus), and mexican free-tailed bats (tadarida brasiliensis) are the most common bats species in the united states. these colonial bat species also have the most frequent contact with humans and domestic animals. however, the silver-haired bat (lasionycteris noctivagans) rabv is associated with the majority of human rabies virus infections in the united states and cana ...201323741002
prevalence of neutralizing antibodies to rabies virus in serum of seven species of insectivorous bats from colorado and new mexico, united states.we determined the presence of rabies-virus-neutralizing antibodies (rvna) in serum of 721 insectivorous bats of seven species captured, sampled, and released in colorado and new mexico, united states in 2003-2005. a subsample of 160 bats was tested for rabies-virus rna in saliva. we sampled little brown bats (myotis lucifugus) at two maternity roosts in larimer county, colorado; big brown bats (eptesicus fuscus) at three maternity roosts in morgan county, colorado; and big brown bats at five mat ...201323568912
naturally occurring rabies virus and neutralizing antibody in two species of insectivorous bats of new york colonies of eptesicus fuscus , the big brown bat, and five colonies of myotis lucifugus , the little brown bat, in new york state were sampled for rabies virus and virus-neutralizing antibody. eight of 278 e. fuscus were found to have virus, while 18 of 187 had antibody titers of ≥1:8. one of 333 m. lucifugus yielded virus, while three of 127 had antibody. these data demonstrate the presence of rabies virus as well as immunity to rabies in some insectivorous bats of new york state. evaluat ...197724228955
host and viral traits predict zoonotic spillover from mammals.the majority of human emerging infectious diseases are zoonotic, with viruses that originate in wild mammals of particular concern (for example, hiv, ebola and sars). understanding patterns of viral diversity in wildlife and determinants of successful cross-species transmission, or spillover, are therefore key goals for pandemic surveillance programs. however, few analytical tools exist to identify which host species are likely to harbour the next human virus, or which viruses can cross species ...201728636590
