Wetland environmental conditions associated with the risk of avian cholera outbreaks and the abundance of Pasteurella multocida Wetland environmental conditions associated with the risk of avian cholera outbreaks and the abundance of Pasteurella multocida

Avian cholera is a significant infectious disease affecting waterfowl across North America and occurs worldwide among various avian species. Despite the importance of this disease, little is known about the factors that cause avian cholera outbreaks and what management strategies might be used to reduce disease mortality. Previous studies indicated that wetland water conditions may...

Evaluating red-cockaded woodpeckers for exposure to West Nile Virus and blood parasites Evaluating red-cockaded woodpeckers for exposure to West Nile Virus and blood parasites

A marked decline in the Picoides borealis (Red-cockaded Woodpecker [RCW]) population at Noxubee National Wildlife Refuge, MS, was observed in 2002. Demographic changes - including absence of hatch-year birds, decreases in size of known groups, and loss of known groups-were identified during annual fall surveys and are uncharacteristic of RCW populations. In 2003, a serosurvey of 28 adult...

Vaccination as a potential means to prevent plague in black-footed ferrets: Progress and continuing challenges Vaccination as a potential means to prevent plague in black-footed ferrets: Progress and continuing challenges

This study was conducted to further assess the feasibility of vaccinating black-footed ferrets (Mustela nigripes) against plague (caused by the bacterium Yersinia pestis). On days 0 and 28, 17 postreproductive ferrets were immunized by subcutaneous injection with a recombinant fusion protein containing F1 and V antigens from Y. pestis. Another 17 animals received a placebo by the same...

Association between perfluorinated compounds and pathological conditions in southern sea otters Association between perfluorinated compounds and pathological conditions in southern sea otters

Concentrations of four perfluorinated contaminants, including perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA), were measured in liver tissue from 80 adult female sea otters collected from the California coast during 1992a??2002. Concentrations of PFOS and PFOA were in the ranges of

The fitting of general force-of-infection models to wildlife disease prevalence data The fitting of general force-of-infection models to wildlife disease prevalence data

Researchers and wildlife managers increasingly find themselves in situations where they must deal with infectious wildlife diseases such as chronic wasting disease, brucellosis, tuberculosis, and West Nile virus. Managers are often charged with designing and implementing control strategies, and researchers often seek to determine factors that influence and control the disease process...

Persistence of Pasteurella multocida in wetlands following avian cholera outbreaks Persistence of Pasteurella multocida in wetlands following avian cholera outbreaks

Avian cholera, caused by Pasteurella multocida, affects waterbirds across North America and occurs worldwide among various avian species. Once an epizootic begins, contamination of the wetland environment likely facilitates the transmission of P. multocida to susceptible birds. To evaluate the ability of P. multocida serotype-1, the most common serotype associated with avian cholera in...

Multi-species patterns of avian cholera mortality in Nebraska's rainwater basin Multi-species patterns of avian cholera mortality in Nebraska's rainwater basin

Nebraska's Rainwater Basin (RWB) is a key spring migration area for millions of waterfowl and other avian species. Avian cholera has been endemic in the RWB since the 1970s and in some years tens of thousands of waterfowl have died from the disease. We evaluated patterns of avian cholera mortality in waterfowl species using the RWB during the last quarter of the 20th century. Mortality...
