  • Spatial and Temporal Dynamics of Rabies Virus Variants in Big Brown Bat Populations Across Canada: Footprints of an Emerging Zoonosis
    Molecular Ecology (2010) 19, 2120–2136 doi: 10.1111/j.1365-294X.2010.04630.x Spatial and temporal dynamics of rabies virus variants in big brown bat populations across Canada: footprints of an emerging zoonosis SUSAN A. NADIN-DAVIS,* YUQIN FENG,* DELPHINE MOUSSE,† ALEXANDER I. WANDELER* and STE´ PHANE ARIS-BROSOU†‡ *Centre of Expertise for Rabies, Ottawa Laboratory (Fallowfield), Canadian Food Inspection Agency, Ottawa, Ontario, Canada, †Department of Biology, University of Ottawa, Ottawa, Ontario, Canada, ‡Department of Mathematics and Statistics, University of Ottawa, Ottawa, Ontario, Canada Abstract Phylogenetic analysis of a collection of rabies viruses that currently circulate in Canadian big brown bats (Eptesicus fuscus) identified five distinct lineages which have emerged from a common ancestor that existed over 400 years ago. Four of these lineages are regionally restricted in their range while the fifth lineage, comprising two-thirds of all specimens, has emerged in recent times and exhibits a recent demographic expansion with rapid spread across the Canadian range of its host. Four of these viral lineages are shown to circulate in the US. To explore the role of the big brown bat host in dissemination of these viral variants, the population structure of this species was explored using both mitochondrial DNA and nuclear microsatellite markers. These data suggest the existence of three subpopulations distributed in British Columbia, mid- western Canada (Alberta and Saskatchewan) and eastern Canada (Quebec and Ontario), respectively. We suggest that these three bat subpopulations may differ by their level of female phylopatry, which in turn affects the spread of rabies viruses. We discuss how this bat population structure has affected the historical spread of rabies virus variants across the country and the potential impact of these events on public health concerns regarding rabies.

  • A Persistently Infecting Coronavirus in Hibernating Myotis Lucifugus, the North American Little Brown Bat
    RESEARCH ARTICLE Subudhi et al., Journal of General Virology 2017;98:2297–2309 DOI 10.1099/jgv.0.000898 A persistently infecting coronavirus in hibernating Myotis lucifugus, the North American little brown bat Sonu Subudhi,1 Noreen Rapin,1 Trent K. Bollinger,2 Janet E. Hill,1 Michael E. Donaldson,3 Christina M. Davy,3 Lisa Warnecke,4 James M. Turner,4 Christopher J. Kyle,3 Craig K. R. Willis4 and Vikram Misra1,* Abstract Bats are important reservoir hosts for emerging viruses, including coronaviruses that cause diseases in people. Although there have been several studies on the pathogenesis of coronaviruses in humans and surrogate animals, there is little information on the interactions of these viruses with their natural bat hosts. We detected a coronavirus in the intestines of 53/174 hibernating little brown bats (Myotis lucifugus), as well as in the lungs of some of these individuals. Interestingly, the presence of the virus was not accompanied by overt inflammation. Viral RNA amplified from little brown bats in this study appeared to be from two distinct clades. The sequences in clade 1 were very similar to the archived sequence derived from little brown bats and the sequences from clade 2 were more closely related to the archived sequence from big brown bats. This suggests that two closely related coronaviruses may circulate in little brown bats. Sequence variation among coronavirus detected from individual bats suggested that infection occurred prior to hibernation, and that the virus persisted for up to 4 months of hibernation in the laboratory. Based on the sequence of its genome, the coronavirus was placed in the Alphacoronavirus genus, along with some human coronaviruses, bat viruses and the porcine epidemic diarrhoea virus.

The importance of bats as natural hosts for several important viral zoonoses, including Ebola, Marburg, Nipah, Hendra, and rabies viruses and severe acute respiratory syndrome-coronavirus (SARS-CoV), has been established; however, the large viral population diversity (virome) of bats has been partially deter- mined for only a few of the ϳ1,200 bat species. To assess the virome of North American bats, we collected fecal, oral, urine, and tissue samples from individual bats captured at an abandoned railroad tunnel in Maryland that is cohabitated by 7 to 10 different bat species. Here, we present preliminary characterization of the virome of three common North American bat species, including big brown bats (Eptesicus fuscus), tricolored bats (Perimyotis subflavus), and little brown myotis (Myotis lucifugus).

  • Using Trace Elements to Identify the Geographic Origin of Migratory Bats
    Using trace elements to identify the geographic origin of migratory bats Jamin G. Wieringa1,2, Juliet Nagel3, David M. Nelson3, Bryan C. Carstens1 and H. Lisle Gibbs1,2 1 Department of Evolution, Ecology, and Organismal Biology, The Ohio State University, Columbus, OH, United States of America 2 Ohio Biodiversity Conservation Partnership, Columbus, OH, United States of America 3 University of Maryland Center for Environmental Science, Appalachian Lab, Frostburg, MD, United States of America ABSTRACT The expansion of the wind energy industry has had benefits in terms of increased renewable energy production but has also led to increased mortality of migratory bats due to interactions with wind turbines. A key question that could guide bat-related management activities is identifying the geographic origin of bats killed at wind-energy facilities. Generating this information requires developing new methods for identifying the geographic sources of individual bats. Here we explore the viability of assigning geographic origin using trace element analyses of fur to infer the summer molting location of eastern red bats (Lasiurus borealis). Our approach is based on the idea that the concentration of trace elements in bat fur is related through the food chain to the amount of trace elements present in the soil, which varies across large geographic scales. Specifically, we used inductively coupled plasma–mass spectrometry to determine the concentration of fourteen trace elements in fur of 126 known-origin eastern red bats to generate a basemap for assignment throughout the range of this species in eastern North America. We then compared this map to publicly available soil trace element concentrations for the U.S.

  • Bats Interim Guidance for Wildlife Management Agencies
    CWHC NATIONAL OFFICE Western College of Veterinary Medicine 52 Campus Dr, Saskatoon, SK S7N 5B4 PH. 1.306.966.5099 EM: [email protected] Wildlife health and SARS-CoV-2 in Canada: Bats Interim guidance for wildlife management agencies Version 1.2, dated: 11 March 2021 Executive summary The susceptibility of all Canadian wildlife to SARS-CoV-2 is not known, but case reports indicate that some species are susceptible to infection. The health of North American bat species is of particular concern due to white-nose syndrome already threatening bat populations. A precautionary approach is advised to protect bats from potential infection with SARS-CoV-2 until more information is available. The goal of this document is to provide recommendations to federal, provincial, territorial, and other wildlife agencies and staff to manage and reduce the risk of transmission of SARS-CoV-2 to bats while also helping ensure that the COVID-19 pandemic does not lead to inappropriate measures taken against wildlife species or populations, or negatively impact wildlife conservation. Currently, the Canadian Wildlife Health Cooperative (CWHC) recommends that only handling of wild bats deemed important for bat conservation be conducted in Canada until the risks associated with SARS-CoV-2 are better understood. Precautionary approaches: • It is recommended that research requiring handling of, or close proximity to, wild bats that is deemed important for bat conservation is conducted with the use of appropriate Personal Protective Equipment (PPE), and that bat handling activities not deemed important for bat conservation be postponed. • For bat rehabilitation, risk assessments should be done on a case-by-case basis to assess whether a centre can accept and release bats.

  • Terr–12 Special-Status Bat Species
    TERR–12 SPECIAL-STATUS BAT SPECIES 1.0 EXECUTIVE SUMMARY During 2001 and 2002, review of existing information and focused bat surveys (roost, mist-netting, and acoustic surveys) were completed. Prior to the surveys, there were no known occurrences of special-status bat species within 1 mile of the Study Area. Ten special-status bat species were determined to potentially occur in the Study Area based on habitat and elevation. None of these ten species are state or federally listed, candidate, or proposed species. Three of these ten species are Forest Service Sensitive species (western red bat (Lasiurus blossevillii), Townsend’s big- eared bat (Corynorhinus townsendii), and pallid bat (Antrozous pallidus)). The remaining seven of these species are federal or state species of special concern (Yuma myotis (Myotis yumanensis), long-eared myotis (Myotis evotis), fringed myotis (Myotis thysanodes), long-legged myotis (Myotis volans), western small-footed myotis (Myotis ciliolabrum), spotted bat (Euderma maculatum), and western mastiff bat (Eumops perotis)). Nine special-status bat species were detected within the Study Area during surveys for this study plan. These include all of the species mentioned above with the exception of western red bat, which was not detected in the Study Area. Twenty- eight of the 71 Big Creek ALP facilities that were surveyed had signs of bat activity. Nine of the 28 facilities had signs of special-status bat activity. These include long- eared myotis at Florence Lake Work Camp; Townsend’s big-eared bat at the 102” Valve House and at West Portal Glory Hole Winch House; long-legged myotis, pallid bat, and fringed myotis at Million Dollar Mile Road Adit 1; long-legged myotis, pallid bat, fringed myotis, Yuma myotis, and long-eared myotis at Million Dollar Mile Road Adit 2 and at Million Dollar Mile Road Adit 3.
