Survey of the U.S. Gulf Coast for the Presence of Clostridium botulinum

Technological Laboratory, U.S. Bureau of Commercial Fisheries, Pascagoula, Mississippi 39567

ABSTRACT

In sediments and animals collected during warm weather months between Key West, Fla., and Brownsville, Tex., Clostridium botulinum, predominantly type E, was demonstrable. Incidence was somewhat higher in the eastern Gulf animals, but the organism was present to the southernmost limits of both Texas and Florida. Types A and F were never detected in warm weather. No bottom type or any single species seemed exclusively vulnerable. In samples collected during colder weather, the east-west incidence differential was minimized in animals but not in sediments, overall incidence was lowered, all known types were present, and type E no longer predominated. Detection by fluorescent-antibody techniques was found to be inadequate.
