Prairie dog trapping locations treated with plague or vaccine baits in western states

The data were collected to determine the density and abundance of prairie dogs in relation to treatment with vaccine or placebo baits and the occurrence of plague.

Pathological findings by fixative time and formulation for Porites evermanni and Montipora capitata

Collections for histopathology in corals require holding of samples in seawater for a time before they are fixed for histopathology processing. This could adversely affect interpretation of morphologic changes during histopathology examinations. We evaluated microscopic morphology of Porites evermanni and Montipora capitata, held (0-120 min) in seawater prior to fixation in Z-Fix...

Pathology of lesions in corals from the US Virgin Islands data release

Stony coral tissue loss disease (SCTLD) was first documented in Florida in 2014 and has since spread through the Caribbean causing unprecedented mortality in over 20 species of corals. The cause of SCTLD is unknown, but bacteria are suspected based on regression of gross lesions in some corals treated with antibiotics. Limited pathology studies on SCTLD exist, but it is likely that...

Indiana Amphibian Pathogen Surveillance data release

Data in this dataset were collected as a part of a surveillance project for reintroduction of a state endangered species in Indiana. This data was collected in the field by state biologists and sent to the USGS National Wildlife Health Center (NWHC) for testing of four amphibian pathogens, Batrachochytrium dendrobatidis (Bd), Batrachochytrium salamandrivorans (Bs), Ranavirus, and...

Avian disease screening of translocated sage grouse captured in Montana, USA

The purpose of this project is to determine the infectious status and exposure status of several diseases that have the potential to impact the health of greater sage grouse (Centrocercus urophasianus) captured in Montana, USA to be translocated to Alberta, Canada. Specific disease status to be tested include, infection with avian influenza virus (AIV), infection with Avian Paramyxovirus...

Arsenic levels in necropsied Sonora mud turtles from Montezuma Well, Arizona in 2015

Montezuma Well is an unusual fishless desert wetland in central Arizona. Water in the Well is naturally enriched with >100 g/L dissolved geogenic arsenic (As) and supports a relatively simple aquatic desert food web with several endemic invertebrate species. Previous studies of As among various environmental compartments and organisms in Montezuma Well have not included turtles despite...

Data Release for Replicate amphibian swab and standard dilution of artificial DNA data to assess qPCR and sampling detection error for Batrachochytrium dendrobatidis.

We generated a data set from by collecting duplicate swabs from all amphibian individuals sampled at 5 sites (96 individuals) and analyzed these duplicate swabs running 3 subsamples of the extracted DNA in separate qPCR reactions. The resulting data set included 2 swabs per individual with 1 qPCR result and a 2nd swab with 3 qPCR results for detection of Batrachochytrium dendrobatidis...

Little Brown Bats (Myotis lucifugus) weights and Ct values for SARS-CoV-2 Infection challenge

Little brown bat (Myotis lucifugus) weights and SARS-CoV2 test results were collected as part of study to assess transmission potential of SARS-CoV2 in North American bat populations. It has been proposed that the SARS-CoV-2 virus originated in Asian bats and subsequently spread through human populations as a pandemic. There is concern that infected humans could transmit the virus to...

2018 Embarrass River Microsporidia

During an epidemiologic survey following a mortality event of freshwater mussels in 2018 in the Embarrass River, Wisconsin, USA, we identified a novel microsporidian parasite in the ovary of mucket (Actinonaias ligamentina), plain pocketbook (Lampsilis cardium), and fatmucket (Lampsilis siliquoidea) (Unioinidae). Histopathology showed round-to-oval microsporidial spores in the cytoplasm...

2011 and 2017 Pika Pathology Colorado

American pikas (Ochotona princeps) are small lagomorphs that live in mountainous talus areas of western North America. Studies on the histopathology of American pikas are limited. This report summarizes the clinical histories, and gross and histologic findings of 12 American pikas, including nine captive and three wild animals. Death was often attributed to stress (transport, handling...

Dataset: Sero-surveillance for avian influenza exposure in wild birds in Iceland, 2012-2017

From 2010-2018 we investigated the occurrence of avian influenza antibody in wild birds in Iceland. A total of 2453 serum samples were collected from wild birds. We tested all samples by enzyme-linked immunosorbent assay (ELISA) for evidence of previous exposure to avian influenza virus with 1302 testing positive.

Chronic Wasting Disease distribution in the United States by state and county (ver. 2.0, April 2024)

Chronic Wasting Disease (CWD) is a fatal, contagious, neuro-degenerative disease affecting multiple members of the Family Cervidae. First detected in 1967, the disease has, as of March 2021, been documented in free-ranging and/or captive cervid populations in 26 states, three Canadian provinces, the Republic of South Korea, Norway, Sweden, and Finland. The data provided here contains...
