A new serotype, Salmonella alachua,2 is represented by one culture isolated during a study of salmonellosis in swine in Florida. The culture was isolated from a sample of soil taken from a pen or holding lot in which swine were kept prior to slaughter. The soil was heavily contaminated with feces. The sample was collected by inserting a sterile dry swab into the moist ground and then placing the swab directly into tetrathionate enrichment broth which subsequently was streaked on a brilliant green agar plate. Salmonella anatum was isolated also from this soil specimen. The organism possessed the cultural and biochemical characteristics of the Salmonella. Acid and gas were produced from glucose, mannite, maltose, xylose, arabinose, inositol, trehalose, sorbitol, and dulcitol. Lactose, sucrose, salicin, adonitol, and raffinose were not fermented. Hydrogen sulfide was produced, citrate
