title: Waterborne Yersinia enterocolitica in the midwest United States.
abstract: One hundred forty strains of waterborne Y. enterocolitica were isolated from Wisconsin and Colorado rivers, lakes and wells between October 1974 and March 1976- Direct-plating of unconcentrated water specimens on deoxycholate-citrate-mannitol (Y-M) agar resulted in 89 isolates. Prolonged incubation of specimens in cooked meat broth produced 51 additional strains. Most organisms were indole-positive, Niléln biotype 1 with 24% belonging to the rhamnophilum subgroup. Twenty-three serotypes were represented with 13% reacting as 0:4,32/33, 43% of the isolates could not be serotyped. Twelve organisms were phagetyped as either XO or XZ.
