Pathogen Exposure

This visualization tool helps researchers and public health officials see how relations between poultry density and waterfowl migration routes affect the threat of avian influenza to people and the poultry industry.

The first known hepatitis B virus to infect fish (white sucker; Catostomus commersonii ) has been discovered by U.S. Geological Survey (USGS) scientists.

Scientists from the U.S. Geological Survey (USGS) are helping to track the movement of three strains of highly pathogenic avian influenza viruses (HPAIV) in wild birds. HPAI viruses are a concern as they are very pathogenic to poultry and some species of wild birds such as raptors. Infection can result in significant mortality of poultry and impact international trade of poultry products. In...

A prime suspect has been identified as a probable cause of the "Sea Star Wasting Disease," a mysterious epidemic that has been killing these animals in droves along the U.S. and Canadian Pacific Coast. Researchers from Cornell University, the U.S. Geological Survey (USGS), and other institutions published their findings on this "sea star associated densovirus (SSaDV)" in the December 2014 issue of...

U.S. Geological Survey (USGS) scientists and collaborators discovered that long-wave ultraviolet (UV) light directed at the wings of bats with white-nose syndrome (WNS) produced points of distinctive orange-yellow fluorescence. The orange-yellow glow corresponds directly with microscopic skin lesions that define the current "gold standard" for diagnosing WNS . White-nose syndrome, a fungal disease...
