Brucellosis in wild swine: a serologic and bacteriologic survey in the southeastern United States and Hawaii.

Sera from wild swine from 20 populations in 11 southeastern states and Hawaii were tested for brucellosis by the card, tube, plate, buffered plate antigen, complement-fixation, and rivanol tests. Twenty-one of 352 (6.0%) swine were considered seropositive, and these animals originated from 7 populations in 5 states: Arkansas, Florida, Georgia, Louisiana, and South Carolina. Cultural examinations for Brucella suis also were made from subsamples of the swine tested serologically. Brucella suis biotype 1 was isolated from lymph nodes or seminal vesicles from wild swine in 2 areas in Florida and 1 in Louisiana.
