New Approach May Detect Chronic Wasting Disease Earlier, at Less Cost

A new statistical approach to disease surveillance may improve scientists’ and managers’ ability to detect chronic wasting disease earlier in white-tailed deer by targeting higher-risk animals. This approach can also provide financial and personnel savings for agencies that are required to monitor for wildlife diseases, including the National Park Service, or NPS.

Detection of Bisgaard taxon 40 in Rhinoceros Auklets (Cerorhinca monocerata) with pneumonia and septicemia from a mortality event in Washington, USA

We isolated Bisgaard taxon 40 from Rhinoceros Auklets (Cerorhinca monocerata) with pneumonia and septicemia from Washington, US, found dead in 2016. Previously isolated only from the respiratory tract of a gull (Laridae), little is known about its pathogenic potential and whether it acts as a primary or opportunistic pathogen.

Predicting the initial spread of novel Asian origin influenza A viruses in the continental USA by wild waterfowl

Using data on waterfowl band recoveries, we identified spatially explicit hotspots of concentrated waterfowl movement to predict occurrence and spatial spread of a novel influenza A virus (clade introduced from Asia by waterfowl from an initial outbreak in North America in November 2014. In response to the outbreak, the hotspots of...
