Summary of Bering and Chukchi Seas seabird necropsies, 2017-2021. More than 14,000 dead seabirds were reported and a total of 117 carcasses were examined. 92 cases had emaciation identified as the Cause Of Death (COD), seven cases where COD was undetermined, and 17 cases where COD was determined as "Other", which included predation, trauma, encephalitis, peritonitis, and bacterial infection. Low Pathogenic Avian Influenza (n=4) and saxitoxin (n=15) were also detected; however, the virus and biotoxin were not determined to be the COD except for one case in 2020 where saxitoxin toxicosis was suspected.

In summer 2020, SARS-CoV-2 was detected on mink farms in Utah. An interagency One Health response was initiated to assess the extent of the outbreak and included sampling animals from or near affected mink farms and testing them for SARS-CoV-2 and non-SARS coronaviruses. Among the 365 animals sampled, including domestic cats, mink, rodents, raccoons, and skunks, 261 (72%) of the animals harbored at least one coronavirus at the time. Among the samples which could be further characterized, 126 alphacoronaviruses and 88 betacoronaviruses (including 74 detections of SARS-CoV-2) were identified. Moreover, at least 10% (n=27) of the corona-virus-positive animals were found to be co-infected with more than one coronavirus....

Stony coral tissue loss disease (SCTLD) was first documented in 2014 near the Port of Miami, Florida, and has since spread north and south along Florida’s Coral Reef, killing large numbers of more than 20 species of coral and leading to the functional extinction of at least one species, Dendrogyra cylindrus. SCTLD is assumed to be caused by bacteria based on presence of different molecular assemblages of bacteria in lesioned compared to apparently healthy tissues, its apparent spread among colonies, and cessation of spread of lesions in individual colonies treated with antibiotics. However, light microscopic examination of tissues of corals affected with SCTLD have not shown bacteria associated with tissue death....

During 2015, beachcast bird survey programs (Beach Watch and BeachCOMBERS) reported higher than average deposition of common murres (Uria aalge) on central and northern California beaches from August through December. Increased common murre mortality was not reported for southern California beaches. International Bird Rescue (IBR) located in Fairfield, CA and other coastal wildlife rehabilitation centers received more than 1,000 live, stranded and debilitated murres from Sonoma County to San Luis Obispo County during August – October. Approximately 2/3 of birds admitted to IBR were after-hatch-year birds in emaciated body condition and in various stages of molt, with extremely worn plumage. To determine the probable...

Rabbit hemorrhagic disease, a notifiable foreign animal disease in the USA, was reported for the first time in wild native North American rabbits and hares in April 2020 in the southwestern USA. Affected species included the Desert Cottontail (Sylvilagus audubonii), Mountain Cottontail (S. nutallii), Black-tailed Jackrabbit (Lepus californicus), and Antelope Jackrabbit (L. alleni). Desert Cottontails (n=7) and Black-tailed Jackrabbits (n=7) collected in April and May 2020 were necropsied at the U.S. Geological Survey National Wildlife Health Center (NWHC) and tested positive for Lagovirus europaeus GI.2, also known as rabbit hemorrhagic disease virus 2 (GI.2/RHDV2/b), by real-time PCR at the U.S. Department of Agriculture’s...
This data set contains individual adult bighorn sheep entry and exit/censor times for 3 disease states and 2 mortality states: susceptible, infected and recovered and disease-caused death and non-disease related death. These times are used in a time-to-event analysis that employs a mixture model approach to characterize transition rates between states.
White-nose syndrome (WNS), a fungal disease that has caused catastrophic population declines of bats in eastern North America, is rapidly spreading across the continent and now threatens previously unexposed bat species in western North America. The causal agent of WNS, Pseudogymnoascus destructans, can infect many species of hibernating bats, but susceptibility to WNS varies by host species. Predicting which western bat species will be most susceptible to WNS would be of great value for establishing conservation priorities. We previously reported that certain traits of the skin microbiome of bat species in eastern North America were strongly associated with tolerance to WNS. Using these traits, we developed a model...
