West Nile virus (avian) case definition for wildlife

Diagnostic laboratories receive carcasses and samples for diagnostic evaluation and pathogen/toxin detection. Case definitions bring clarity and consistency to the evaluation process. Their use within and between organizations allows more uniform reporting of diseases and etiologic agents. The intent of a case definition is to provide scientifically based criteria for determining (a) if an individ

Analysis of mitochondrial DNA sequence data demonstrates that monophyly of myotis occultus is complicated by greater sampling of myotis lucifugus

The validity of Myotis occultus as a species unique from Myotis lucifugus has been a source of debate. Most recently, many authorities treat M. occultus as a distinct species, at least in part because a previous study showed that M. occultus and M. l. carissima (the subspecies that occurs in closest geographic proximity to M. occultus) form separate monophyletic clades based on sequences of two mi

Expanding Distribution of Chronic Wasting Disease

Chronic wasting disease (CWD) has been detected in 33 US states and five Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 33 states and four provinces and in captive cervid facilities in 19 states and three provinces.

Application of a systems approach for management of chronic wasting disease

The USGS National Wildlife Health Center, Montana Cooperative Wildlife Research Unit, Ventana Systems, Inc. , and the Wisconsin Department of Natural Resources (WIDNR) are applying a systems approach to map and model the complex relationships among ecological, epidemiological, social, and political processes affecting CWD. Through a participatory modeling process, we gathered subject matter...
