Abstract
Yersinia enterocolitica has been isolated from a wide variety of sources throughout the world. The isolation of this organism requires special awareness from bacteriologists. To ease this procedure, we have developed a new isolation medium—BABY 4—meant to be used for environmental studies. Compared with previously recommended media, such as SS agar, SS-D agar, and urea-novobiocin agar, it allows easy detection ofY. enterocolitica in various types of waters. It counterselects Enterobacteriaceae species fromY. enterocolitica in a ratio of 10−1 to 10−5 and makes quantitative studies of environmental sources possible. This medium also allows the detection after 3–4 days' incubation of as few as 103 Y. enterocolitica per gram of stool.
