Mott at the National Animal Disease Laboratory from epithelium from snout of adult domestic pig (Suis) on farm in vicinity of Hazelhurst, Jeff Davis County, Georgia, Lat. 31° 50′ N, Long. 82° 35′ W. Epithelium taken 16 May 1952 from pig showing vesicle formation on snout, salivation, and elevated temperature. Habitat: Farm, with pigs running into woodland. Storage: Vesicle epithelium transported on ice to laboratory.
