This dataset is one table with results of tests to determine exposure of Chukchi Sea polar bears to a suite of pathogens. Results are serological tests for antibodies and tests of fecal samples for presence of parasites. Serologic assays were conducted for Toxoplasma gondii, Neospora caninum, Francisella tularensis, Coxiella burnetii, Leptospira spp., Brucella canis, Brucella abortus/suis, and canine distemper virus. Parasitology analyses were conducted for presence of Giardia cysts and Cryptospiridium oocysts in fecal samples. Polar bears were sampled on sea ice in the Chukchi Sea between mid-March and early May 1987-1994 and 2008-2017. The dataset includes relevant information about the bears that were captured...

Lake Sinai Viruses (LSV) are common ribonucleic acid (RNA) viruses of honey bees (Apis mellifera) that frequently reach high abundance but are not linked to overt disease. LSVs are genetically heterogeneous and collectively widespread, but despite frequent detection in surveys, the ecological and geographic factors structuring their distribution in A. mellifera are not understood. Even less is known about their distribution in other species. Better understanding of LSV prevalence and ecology have been hampered by high sequence diversity within the LSV clade. We developed a new genetic assay that detects all currently known lineages. We also performed pilot metagenetic sequencing to quantify the diversity of LSV...

The threat posed by infectious diseases are a major concern for global public health and the role of migratory birds in pathogen transmission is increasingly under scrutiny. Enteric viral pathogen surveillance in migratory birds is a critical component of outbreak preparedness. The shedding of such pathogens through excrement into bodies of water located at migratory stop-over sites and breeding and wintering grounds creates conditions to potentially infect millions of birds annually. The mallard is the most abundant of all duck species and migratory across much of its range. Here we characterized enteric viral pathogens from the cecum of 16 captive raised mallards (Anas platyrhynchos) from Wisconsin, USA using...
