The expectations and challenges of wildlife disease research in the era of genomics: forecasting with a horizon scan-like exercise
The outbreak and transmission of disease-causing pathogens are contributing to the unprecedented rate of biodiversity decline. Recent advances in genomics have coalesced into powerful tools to monitor, detect, and reconstruct the role of pathogens impacting wildlife populations. Wildlife researchers are thus uniquely positioned to merge ecological...Fitak, Robert R.; Antonides, Jennifer D.; Baitchman, Eric J.; Bonaccorso, Elisa; Braun, Josephine; Kubiski, Steven; Chiu, Elliott; Fagre, Anna C.; Gagne, Roderick B.; Lee, Justin S.; Malmberg, Jennifer L.; Stenglein, Mark D.; Dusek, Robert J.; Forgacs, David; Fountain-Jones, Nicholas M.; Gilbertson, Marie L.

USGS-NWHC Quarterly Wildlife Mortality Report - January 2019
The USGS National Wildlife Health Center (NWHC) Quarterly Mortality Report provides brief summaries of epizootic mortality and morbidity events by quarter. The write-ups, highlighting epizootic events and other wildlife disease topics of interest, are published in the Wildlife Disease Association quarterly newsletter. A link is provided in this...Richards, Bryan J.; Bodenstein, Barbara; Dusek, Robert J.; Rocke, Tonie E.; Richgels, Katherine L. D.
Mortality of little brown bats (Myotis lucifugus carissima) naturally exposed to microcystin-LR
We describe a die-off of little brown bats (Myotis lucifugus carissima) associated with acute intoxication with microcystin-LR in 2016 at Scofield Reservoir in Utah. High levels of this cyanotoxin in water from the reservoir and gastrointestinal content of bats supported this diagnosis.Isidoro Ayza, Marcos; Jones, Lee C.; Dusek, Robert J.; Lorch, Jeffrey M.; Landsberg, Jan H.; Wilson, Patrick; Graham, Stephanie

Chlamydia psittaci in feral Rosy-faced Lovebirds (Agapornis roseicollis) and other backyard birds in Maricopa County, Arizona
In 2013, a mortality event of nonnative, feral Rosy-faced Lovebirds (Agapornis roseicollis) in residential backyards in Maricopa County, Arizona, US was attributed to infection with Chlamydia psittaci. In June 2014, additional mortality occurred in the same region. Accordingly, in August 2014 we sampled live lovebirds and sympatric bird...Dusek, Robert J.; Justice-Allen, Anne; Bodenstein, Barbara; Knowles, Susan N.; Grear, Daniel A.; Adams, Laura; Levy, Craig; Yaglom, Haley D.; Shearn-Bochsler, Valerie I.; Ciembor, Paula; Gregory, Christopher R.; Pesti, Denise; Ritchie, Branson W.
Grass is not always greener: Rodenticide exposure of a threatened species near marijuana growing operations
ObjectiveMarijuana (Cannabis spp.) growing operations (MGO) in California have increased substantially since the mid-1990s. One environmental side-effect of MGOs is the extensive use of anticoagulant rodenticides (AR) to prevent damage to marijuana plants caused by wild rodents. In association with a long-term demographic study, we report on...Franklin, Alan B.; Carlson, Peter C.; Rex, Angela; Rockweit, Jeremy T.; Garza, David; Culhane, Emily; Volker, Steven F; Dusek, Robert J.; Shearn-Bochsler, Valerie I.; Gabriel, Mourad W.; Horak, Katherine E.

Inferring epidemiologic dynamics from viral evolution: 2014–2015 Eurasian/North American highly pathogenic avian influenza viruses exceed transmission threshold, R0 = 1, in wild birds and poultry in North America
Highly pathogenic avian influenza virus (HPAIV) is a multihost pathogen with lineages that pose health risks for domestic birds, wild birds, and humans. One mechanism of intercontinental HPAIV spread is through wild bird reservoirs, and wild birds were the likely sources of a Eurasian (EA) lineage HPAIV into North America in 2014. The introduction...Grear, Daniel R.; Hall, Jeffrey S.; Dusek, Robert J.; Ip, Hon S.
Potential for water borne and invertebrate transmission of West Nile virus in the Great Salt Lake, Utah
In November and December of 2013, a large mortality event involving 15,000 - 20,000 eared grebes (Podiceps nigricollis) occurred at the Great Salt Lake (GSL), UT. The onset of the outbreak in grebes was followed by a mortality event in > 86 bald eagles (Haliaeetus leucocephalus). During the die-off, West Nile virus (WNV) was detected by RT-PCR...Lund, Melissa; Shearn-Bochsler, Valerie I.; Dusek, Robert J.; Shivers, Jan; Hofmeister, Erik K.

No evidence of infection or exposure to Highly Pathogenic Avian Influenzas in peridomestic wildlife on an affected poultry facility
We evaluated the potential transmission of avian influenza viruses (AIV) in wildlife species in three settings in association with an outbreak at a poultry facility: 1) small birds and small mammals on a poultry facility that was affected with highly pathogenic AIV (HPAIV) in April 2015; 2) small birds and small mammals on a nearby poultry...Grear, Daniel A.; Dusek, Robert J.; Walsh, Daniel P.; Hall, Jeffrey S.
