Post-epizootic surveys of waterfowl for duck plague (duck virus enteritis) Post-epizootic surveys of waterfowl for duck plague (duck virus enteritis)

Surviving birds from nine duck plague outbreaks in urban and confined waterfowl were sampled for duck plague (DP) virus and DP antibody during 1979-86. Duck plague virus was found in combined oral and cloacal swabs of birds from three outbreaks, and DP-neutralizing antibody was demonstrated in some birds from all nine outbreaks. Greater prevalence of DP antibody and higher titers were...

Avian morbidity and mortality from botulism, aspergillosis, and salmonellosis at Jamaica Bay Wildlife Refuge, New York, USA Avian morbidity and mortality from botulism, aspergillosis, and salmonellosis at Jamaica Bay Wildlife Refuge, New York, USA

During the summers of 1981 and 1982, studies were conducted at Jamaica Bay Wildlife Refuge, Long Island, New York, to determine whether annual water-level drawdowns used to create shorebird habitat also led to the occurrence of avian botulism (Clostridium botulinum type C). Low levels of morbidity and mortality from avian botulism occurred on the two ponds throughout both summers, but...

Septicemic pasteurellosis in elk (Cervus elaphus) on the United States National Elk Refuge, Wyoming Septicemic pasteurellosis in elk (Cervus elaphus) on the United States National Elk Refuge, Wyoming

Septicemic pasteurellosis caused by Pasteurella multocida is believed responsible for the deaths of 48 elk (Cervus elaphus) on the National Elk Refuge near Jackson, Wyoming (USA) during 1986 and 1987. Clinical signs included depression and salivation; necropsy findings included congestion and petechial and ecchymotic hemorrhages in lymph nodes, diaphragm, lungs and endocardium...

A survey of the prevalence of selected bacteria in wild birds A survey of the prevalence of selected bacteria in wild birds

We determined the prevalence of six genera of bacteria from a sample of 387 cloacal swabs from 364 passerines and woodpeckers. The prevalence of bacteria were as follows: Escherichia coli (1%), Pseudomonas spp. (22%), Salmonella spp. (0%), Staphylococcus spp. (15%), Streptococcus spp. (18%), and Yersinia spp. (1%). The prevalence of Streptococcus spp. was higher in omnivorous species...

Use of muscovy duck embryo fibroblasts for the isolation of viruses from wild birds Use of muscovy duck embryo fibroblasts for the isolation of viruses from wild birds

Techniques are described for the preparation, cryopreservation, and inoculation of Muscovy duck embryo cell cultures. The procedure yields a susceptible reproducible cell culture system for the isolation and cultivation of viruses from wild birds.

Hematozoan parasites of Rio Grande wild turkeys from southern Texas (USA) Hematozoan parasites of Rio Grande wild turkeys from southern Texas (USA)

One hundred twenty-three of 300 blood samples (41%) taken from Rio Grande wild turkeys (Meleagris gallopavo intermedia) from three locations in southern Texas (Welder Wildlife Refuge, Chaparrosa Ranch, and Campo Alegre Ranch) and subinoculated into domestic broad-breasted white turkey poults were positive for a Plasmodium (Novyella) sp. Analysis of blood films from 350 turkeys revealed

Characterization of an avian cholera epizootic in wild birds in western Nebraska Characterization of an avian cholera epizootic in wild birds in western Nebraska

Avian cholera killed an estimated 2500 birds in western Nebraska and eastern Wyoming from 28 November 1985 to late January 1986. Wild mallards (Anas platyrhynchos) suffered the most losses. Other wild waterfowl, wild turkeys (Meleagris gallopavo), a few domestic fowl, and a bald eagle (Haliaeetus leucocephalus) also died. Pasteurella multocida serotype 1 was the predominant isolate from...
