An outbreak of duck virus enteritis (duck plague) in a captive flock of mixed waterfowl An outbreak of duck virus enteritis (duck plague) in a captive flock of mixed waterfowl

An outbreak of duck virus enteritis occurred in a flock of captive waterfowl composed of mallards (Anas platyrhynchos), black ducks (Anas rubripes), and Canada geese (Branta canadensis). Although all three species were housed together, morbidity and mortality were confined to the 227 black ducks and Canada geese, of which 180 died and the rest were left in a weakened condition. Lesions...

Eustrongylides and pesticide levels in a great blue heron shot in Wisconsin Eustrongylides and pesticide levels in a great blue heron shot in Wisconsin

The parasitic roundworm, Eustrongylides ignotus Jagersk, has been known to cause mortality and morbidity in members of the heron family in the eastern states of North America. To date no previous records exist for this nematode in Wisconsin. Even though eustrongylidiosis was first detected in the District of Columbia in 1926 by Chapin (1926), it was not until 1976 that this parasite was...

Key to trematodes reported in waterfowl Key to trematodes reported in waterfowl

This key is the second in a series for identification of the helminths reported in waterfowl (Family Anatidae, Order Anseriformes). The first was a key to nematodes (McDonald 1974). The trematodes show the greatest variety of forms among the helminth parasites of waterfowl, including over half of all species reported; sometimes this group also includes the greatest part of the worms in a...

Naturally occurring and experimentally induced castor bean (Ricinus communis) poisoning in ducks Naturally occurring and experimentally induced castor bean (Ricinus communis) poisoning in ducks

Castor bean (Ricinus communis) poisoning accounted for the death of several thousand ducks in the Texas panhandle in the fall and winter months of 1969-1971. Signs of intoxication resembled those of botulism, except for mucoid, blood-tinged excreta. The most common lesions were severe fatty change in the liver, widely distributed internal petechial hemorrhages or ecchymoses, and...

Evaluation of coproexamination as a diagnostic test for avian botulism Evaluation of coproexamination as a diagnostic test for avian botulism

Fecal extracts and blood sera from 113 ducks showing clinical signs of botulism were examined for Clostridium botulinum type C toxin by means of the mouse toxicity test to evaluate coproexamination as a diagnostic procedure, as compared with demonstration of toxin in serum. When death of test mice unprotected with type specific antitoxin (while protected controls survived) was the...

Organochlorine residues and mortality of herons Organochlorine residues and mortality of herons

Since 1966, 72 herons found dead or moribund in the field have been analyzed for organochlorine chemicals. In addition, 36 herons were obtained through systematic collections, and carcasses were analyzed to determine sublethal exposure to organochlorines. Brains of birds found dead or moribund were analyzed to determine whether the birds had died of organochlorine poisoning. Residues of...
