This bibliography, first compiled in 1970 (Allen and Wilson 1977) and published in 1977 in response to many requests for information on avian botulism, has been updated to include the literature published through 1980. In general, only articles dealing primarily with the avian disease are included, as opposed to those concerned with the various aspects of the biology of Clostridium...

Chlamydiosis (ornithosis, psittacosis) is an infectious disease of birds that can be transmitted to humans. Human infections are probably acquired by inhalation of aerosols containing elementary bodies of the causative agent Chlamydia psittaci, from bird droppings, or from tissues. Infected birds do not have to be ill to transmit the organism (Schachter and Dawson 1978). The disease in...

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...

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...

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...

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...

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...
