Abstract
Water samples collected over a 14-mo. period from the lower Chippewa River drainage basin in Wisconsin were examined for Y. enterocolitica with MacConkey-Tween 80 agar or Y-M agar as the selective medium. A new method of isolation was developed. Of 303 water samples, 8.25% were positive. A seasonal variation was noticed, with winter isolations being most frequent.
