Soil clay content underlies prion infection odds Soil clay content underlies prion infection odds

Environmental factors—especially soil properties—have been suggested as potentially important in the transmission of infectious prion diseases. Because binding to montmorillonite (an aluminosilicate clay mineral) or clay-enriched soils had been shown to enhance experimental prion transmissibility, we hypothesized that prion transmission among mule deer might also be enhanced in ranges...

Chiggers recently infesting Spea spp., in Texas, USA, were Eutrombicula alfreddugesi, not Hannemania sp. Chiggers recently infesting Spea spp., in Texas, USA, were Eutrombicula alfreddugesi, not Hannemania sp.

Upon re-examination of preserved larval chiggers collected from spadefoot toads (Spea bombifrons and Spea multiplicata) in the Southern High Plains of Texas, USA, and identified previously as Hannemania sp., we found them to be Eutrombicula alfreddugesi. A review of previous reports of Eutrombicula spp. chiggers on amphibian hosts provides context for current findings. All members of the...

DNA-based detection of the fungal pathogen Geomyces destructans in soil from bat hibernacula DNA-based detection of the fungal pathogen Geomyces destructans in soil from bat hibernacula

White-nose syndrome (WNS) is an emerging disease causing unprecedented morbidity and mortality among bats in eastern North America. The disease is characterized by cutaneous infection of hibernating bats by the psychrophilic fungus Geomyces destructans. Detection of G. destructans in environments occupied by bats will be critical for WNS surveillance, management and characterization of...

Ranavirus outbreaks in amphibian populations of northern Idaho Ranavirus outbreaks in amphibian populations of northern Idaho

Ranavirus outbreaks, caused by pathogens in the genus Ranavirus (Family Iridoviridae), were the largest single cause of reported amphibian mass mortality events in the United States from 1996–2001 (Green et al. 2002). Mortality events associated with ranaviruses have been documented on five continents and throughout the latitudes and elevations where amphibians occur (Gray et al. 2009)...

Links between type E botulism outbreaks, lake levels, and surface water temperatures in Lake Michigan, 1963-2008 Links between type E botulism outbreaks, lake levels, and surface water temperatures in Lake Michigan, 1963-2008

Relationships between large-scale environmental factors and the incidence of type E avian botulism outbreaks in Lake Michigan were examined from 1963 to 2008. Avian botulism outbreaks most frequently occurred in years with low mean annual water levels, and lake levels were significantly lower in outbreak years than in non-outbreak years. Mean surface water temperatures in northern Lake...

Evaluation of Nobuto filter paper strips for the detection of avian influenza virus antibody in waterfowl Evaluation of Nobuto filter paper strips for the detection of avian influenza virus antibody in waterfowl

The utility of using Nobuto paper strips for the detection of avian influenza antibodies was examined in mallards (Anas platyrhynchos) experimentally infected with low pathogenic avian influenza viruses. Blood was collected 2 wk after infection and was preserved either as serum or whole blood absorbed onto Nobuto strips. Analysis of samples using a commercially available blocking enzyme...

Use of Rhodamine B as a biomarker for oral plague vaccination of prairie dogs Use of Rhodamine B as a biomarker for oral plague vaccination of prairie dogs

Oral vaccination against Yersinia pestis could provide a feasible approach for controlling plague in prairie dogs (Cynomys spp.) for conservation and public health purposes. Biomarkers are useful in wildlife vaccination programs to demonstrate exposure to vaccine baits. Rhodamine B (RB) was tested as a potential biomarker for oral plague vaccination because it allows nonlethal sampling...

Microparasite ecology and health status of common bluestriped snapper Lutjanus kasmira from the Pacific Islands Microparasite ecology and health status of common bluestriped snapper Lutjanus kasmira from the Pacific Islands

Common bluestriped snappers Lutjanus kasmira were intentionally introduced into Hawaii from the South Pacific in the 1950s and have become well established throughout the archipelago. We examined health, prevalence and infection intensity of 2 microparasites, coccidia and epitheliocystis-like organisms (ELO), in L. kasmira from their introduced and native range including the islands...

Global research priorities for sea turtles: Informing management and conservation in the 21st century Global research priorities for sea turtles: Informing management and conservation in the 21st century

Over the past 3 decades, the status of sea turtles and the need for their protection to aid population recovery have increasingly captured the interest of government agencies, non-governmental organisations (NGOs) and the general public worldwide. This interest has been matched by increased research attention, focusing on a wide variety of topics relating to sea turtle biology and...

Relationship between fibropapillomatosis and environmental quality: A case study with Chelonia mydas off Brazil Relationship between fibropapillomatosis and environmental quality: A case study with Chelonia mydas off Brazil

We documented the presence of fibropapillomatosis (FP), a debilitating tumor-forming disease, in marine turtles in Espírito Santo Bay (Brazil) from March 2007 to April 2008, and assessed the value of a specific environmental index for predicting the prevalence of FP. Turtles were captured monthly with entanglement nets and scored for presence and severity of FP. For the assessment of...
