“…Occasional encounters between colonial and solitary species (Constantine, 1967;Schowalter, 1980) suggests the potential for such transfer still exists. However, latency in overwintering bats (Constantine, 1967;Moore and Raymond, 1970), transplacental transmission (Sims et al, 1963;Constantine et al, 1968), transmammary transmission (Sims et al, 1963), the sedentary life style, and the aggressive social behavior of the colonial species (Constantine, 1967), also appear to provide adequate mechanisms to maintain the virus within local populations.…”

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 species of bats in each of Alberta and Saskatchewan, but in seven species in British Columbia. Annual prevalence in rabies-suspect bats was similar in colonial species within each province. Rabies was found rarely in suspect little brown bats (Myotis lucifugus) (< 1 %). In suspect big brown bats (Eptesicus fuscus), the prevalence was low in Saskatchewan (3%), moderate in Alberta (lo%), and high in British Columbia (25%). Big brown bats accounted for over 55% of the rabid bats detected in each province. Annual prevalence reported in silver-haired bats (Lusionycteris noctiuugans) and hoary bats (Lusturus cinereus) was variable in all three provinces. Rabies is enzootic in northern insectivorous bats.

“…The mechanism by which rabies virus infections are maintained in bat populations remains poorly understood (3). Possible routes of transmission of the virus among bats include direct contact (bite), aerosol transmission, ingestion of virus-infected milk from an infected mother, and transplacental infection (4)(5)(6)(7)(8). Reports of natural transplacental transmission are rare and difficult to confirm.…”

“…Such problems regarding bats received little attention (9). Sims et al (8) reported rabies virus in the brain of one of 23 fetuses extracted from several female Mexican free-tailed bats (Tadarida brasiliensis), each of which had previously been inoculated via chest muscles with rabies virus (4). However, although transplacental transfer of rabies virus had been demonstrated in bats under laboratory conditions, it was suggested that prenatal infection of bats with rabies virus does not occur under natural conditions (8,9).…”

Current knowledge on bat lyssavirus infections in their native hosts is limited and little is known about the virulence, virus dissemination and transmission among free-living insectivorous bats. The present study is a brief description of rabies virus (RABV) dissemination in tissues of a naturally infected pregnant southern yellow bat (Lasiurus ega) and its fetuses, obtained by reverse-transcriptase polymerase chain reaction (RT-PCR). The RT-PCR was positive in samples from the brain, salivary gland, tongue, lungs, heart, kidneys and liver. On the other hand, the placenta, three fetuses, spleen, intestine and brown fat tissue tested negative. This research demonstrated the absence of rabies virus in the fetuses, thus, in this specific case, the transplacentary transmission was not observed.

“…Rabies virus has been isolated from brain, salivary glands, mammary glands, and intrascapular brown adipose tissue of bats (Sulkin et al 1959, Sulkin 1962and Sims and Sulkin 1963. Evidence to suggest that viral storage and replication occur in the intrascapular brown fat was provided by Sulkin et al (1959) and Sims and Sulkin (1963).…”

This issue is an actively metabolizing source of nutrition during periods of hibernation or torpor (Wertheimer andShapiro 1948 andRemillard 1958).…”
