An outbreak of pasteurellosis in wild ducks

A report was received by Merovka that a large number of wild ducks had been found dead on a small lake located about 15 miles southwest of Dimmitt, Castro County, Texas. The area was visited by Merovka and U.S. Game Agent Boone, who found and picked up 307 dead ducks, nearly all mallards and pintails. The farmer on whose land the birds were found stated that tot he best of his knowledge and belief the birds had all perished on Feb. 27, 1944. Field examination of the birds indicated that they had died at approximately that time. Only 1 sick bird was observed during the field investigation.

The distribution of botulinus toxin in duck sickness areas

One of the most important events in the history of the diseases of wildfowl wa the discovery of the cause of western duck sickness. Determination that this malady of migratory birds is not a chemical poisoning, as had been previously suspected, was made by Kalmbach and others in 1930-31. Thtat it is a food poisoning resulting from toxins produced by botulinus organisms was proved beyond question. An extensive review of the work leading up to this determination cannot be made in this paper, but some orientation is necessary to a proper appreciation of the subject.
