A multiple typing analysis was carried out on 14 apparently heterogeneous Salmonella typhimurium strains recovered during a 3 week period from an enteritis case. Conjugational transfer of resistance determinants and restriction endonuclease fingerprinting of plasmids allowed the different isolates of S. typhimurium to be attributed to a single clone.
