Considerations for colorblind individuals on selecting colorimetric or fluorescent dye assay outcomes

A disadvantage of colorimetric detection in nucleic acid amplification assays is the possibility that a colorblind individual may interpret colors differently than observers with full-color vision. Using an isothermal amplification assay, the ability of colorblind individuals to distinguish between positive and negative results for four dyes was tested. Five individuals with self-reported colorbli

Broad-scale assessment of methylmercury in adult amphibians

Mercury (Hg) is a toxic contaminant that has been mobilized and distributed worldwide and is a threat to many wildlife species. Amphibians are facing unprecedented global declines due to many threats including contaminants. While the biphasic life history of many amphibians creates a potential nexus for methylmercury (MeHg) exposure in aquatic habitats and subsequent health effects, the broad-scal

Expanding Distribution of Chronic Wasting Disease

Chronic wasting disease (CWD) has been detected in 31 US states and four Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 31 states and three provinces and in captive cervid facilities in 18 states and three provinces.

WHISPers

WHISPers, the Wildlife Health Information Sharing Partnership - event reporting system, is a web-based repository of basic information on current and historic wildlife mortality (death) and/or morbidity (illness) events reported by partners nationwide. It is also the portal to request diagnostic and epidemiologic services from the USGS National Wildlife Health Center.

Examining PRNP gene frequencies and ‘resistance’ to chronic wasting disease

Multiple studies have demonstrated that various alleles of the cervid prion protein (PRNP) gene affect chronic wasting disease (CWD) progression.
