A survey of North American migratory waterfowl for duck plague (duck virus enteritis) virus

A survey of migratory waterfowl for duck plague (DP) virus was conducted in the Mississippi and Central flyways during 1982 and in the Atlantic and Pacific flyways during 1983. Cloacal and pharyngeal swabs were collected from 3,169 migratory waterfowl in these four flyways, principally mallards (Anas platyrhynchos L.), black ducks (Anas rubripes Brewster), and pintails (Anas acuta L). In addition

The occurance of Pterygodermatites nycticebi (Nematoda: Rictulariidae) in a captive slow loris, Nycticebus coucang

Adult and immature rictulariid nematodes were recovered at necropsy from the small intestine of an adult slow loris, Nycticebus coucang, from the Milwaukee County Zoo in Wisconsin. The lumen of the entire small intestine was packed with more than 100 nematodes, the intestinal wall appeared thickened and the mucosal surface contained numerous petechial hemorrhagic foci. The cause of death was diagn

Avian cholera in Nebraska's Rainwater Basin

The first report of avian cholera in North America occurred in northwestern Texas in winter 1944 (Quortrup et al. 1946). In 1975, mortality from avian cholera occurred for the first time in waterfowl in the Rainwater Basin of Nebraska when an estimated 25,000 birds died (Zinkl et al. 1977). Avian cholera has continued to cause mortality in wild birds in specific areas of the Basin each spring sinc

Avian cholera in the central and Mississippi flyways 1979-80

Waterfowl mortality from avian cholera during July 1979-May 1980 was widespread in the Central and Mississippi flyways, occurring in a wide variety of species and locations from nesting grounds of snow geese (Chen caerulescens) on Hudson Bay south to waterfowl wintering areas on the Texas coast and playa lakes region. Mortality estimates at the various sites ranged from several birds to over 72,00

Renal coccidiosis in interior Canada geese, Branta canadensis interior Todd, of the Mississippi Valley population

Kidneys from 309 Interior Canada geese from three locations in the Mississippi Flyway were examined for renal coccidia. Oocysts and/or young zygotes of Eimeria sp. were found in 6.8% of goose kidneys sampled. Only one type of renal coccidian oocyst was observed. Significantly more immature geese were infected than adults; however, there was no significant difference observed between the prevalence

Lead poisoning of sandhill cranes (Grus canadensis)

Two wild and two captive sandhill cranes (Grus canadensis) were diagnosed by National Wildlife Health Laboratory personnel as having died from lead toxicity. Ingestion of lead fishing weights by the wild cranes and of unspent .22 caliber shell cartridges by the captive cranes were responsible for these deaths. One crane force-fed lead pellets showed an increase of blood lead levels from 0.77 ppm t

Chemical immobilization of North American mule deer

The choice of agents for chemical immobilization of mule deer (Odocoileus hemionus) is a problem with a simple and effective solution, in my opinion. I recommend combinations of etorphine hydrochloride (M199©) and xylazine hydrochloride (Rompun©) administered intravenously and reversed intravenously. I have used this combination on hundreds of mule deer and have supervised its use on hundreds more

Effects of dietary ABATE® on reproductive success, duckling survival, behavior, and clinical pathology in game-farm mallards

Forty-four pairs of game-farm mallards (Anas platyrhynchos) were fed ABATE® 4E (temephos) to yield 0, 1, or 10 ppm ABATE® beginning before the initiation of lay, and terminating when ducklings were 21 days of age. The mean interval between eggs laid was greater for hens fed 10 ppm ABATE® than for controls. Clutch size, fertility, hatchability, nest attentiveness of incubating hens, and avoidance b
