Amphibian population declines and deformities due to various causes including land use change, viruses, and fungi. Links to USGS press releases, answers to FAQs (HTML and PDF versions) and photos with downloadable files.
Background information and genetic sequencing data for more than 1,000 individual field isolates of the fish virus Infectious Hematopoietic Necrosis Virus (IHNV) collected in western North America from 1966 to the present, updated annually.
A template database for recording information on individual isolates of aquatic pathogens affecting a variety of aquatic species such as fish or shellfish. Tracks collection, history, geography, gene sequence, and diagnostic info. Uses FileMaker Pro.
Homepage for the Biochemistry and Physiology Branch in Columbia, MO, which develops analytical techniques (cell bioassay/immunoassay) on toxicity related to fish and wildlife; and conducts research in microbiology and physiology.
Describes four communicable diseases (salmonellosis, trichomoniasis, aspergillosis, and avian pox) that can be passed from bird to bird at bird feeders and gives eight relatively easy steps that people can take to prevent or minimize disease.
Manual listing field procedures for bird specimen collecting, bacterial, fungal, parasitic, and viral diseases, biotoxins, chemical toxins, common and scientific names of birds, and glossary. Manual can be downloaded or viewed in PDF format.
The Fish Health Branch, Leetown Science Center, investigates fish health and disease issues associated with genetics, pathogens and environmental stress. With links to workshops, leaflets, and announcements relating for fish health.
The National Wildlife Health Center (NWHC) is a biomedical laboratory assessing the impact of disease on wildlife and identifying the role of various pathogens in wildlife losses. Site has links to news, programs, publications and metadata.
Overview of microbiology projects related to water quality investigating bacteria, viral and protozoan pathogens and indicators in the environment with links to publications, analytical and field methods, laboratory, and current projects.
Describes highly pathogenic avian influenza and explains why this wildlife disease is of concern to health scientists and the public. Diagram shows potential pathways by which the disease could be transmitted to other animals, including humans.
We work with state and Federal agencies to study these diseases of birds because they can affect both wild populations of birds and cultivated poultry, and their diseases can spread to other animals, including humans.
