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

Persistence of Pasteurella multocida in Nebraska wetlands under epizootic conditions Persistence of Pasteurella multocida in Nebraska wetlands under epizootic conditions

Gleason Basin, a marsh located in the western part of the Rainwater Basin in Nebraska, was selected during the 1980 spring waterfowl migration as a study site to determine the presence and persistence of virulent Pasteurella multocida. Avian cholera mortality in migratory waterfowl using the Basin increased during a 2-wk period of a die-off beginning the first week of March when 2,409...

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

Lead poisoning of sandhill cranes (Grus canadensis) 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...

Chemical immobilization of North American mule deer 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...

The white pelican (Pelicanus erythrorhynchos) as a host of Pelecanectes apunctatus (Acarina: Hypoderidae) The white pelican (Pelicanus erythrorhynchos) as a host of Pelecanectes apunctatus (Acarina: Hypoderidae)

Several species of nymphs from the family Hypoderidae have been reported from pelecaniform birds (Cerny, 1969, Folia Parasit. (Praha) 16:271-274; Pence, 1972, J. Med. Ent. 9: 435-438; Pence and Courtney, 1973, J. Parasitol. 59: 711-718); however, there are no records from the white pelican, Pelecanus erythrorhynchos. I report here the occurrence of hypopi from this host species.

Waterbird mortality from botulism type E in Lake Michigan: An update Waterbird mortality from botulism type E in Lake Michigan: An update

Three outbreaks of botulism type E occurring in waterbirds on Lake Michigan since autumn 1976 are discussed. Natural ingestion of food containing type E toxin by Ring-billed Gulls (Larus delawarensis) and the presence of type E toxin in blood from moribund gulls were demonstrated. Concurrent presence of type C and type E botulinal toxins was found in a die-off of Common Loons (Gavia...

Inclusion body disease of cranes: A serological follow-up to the 1978 die-off Inclusion body disease of cranes: A serological follow-up to the 1978 die-off

A herpesvirus was isolated from captive cranes involved in a 1978 die-off. Neutralizing antibody to this virus was detected in this captive population as early as 1975 and consistently thereafter through 1979. Exposure to the virus evidently occurred at least 2 1/2 years before the die-off, without causing any mortality diagnosed as being caused by inclusion body disease of cranes (IBDC)
