An Evaluation of Selective Differential Plating Media for the Isolation of <i>Yersinia enterocolitica</i> from Experimentally Inoculated Fresh Ground Pork Homogenate

Abstract

ABSTRACT Seven selective differential plating media were evaluated for their effectiveness in recovering eight serotypes (0:3; 0:8; 0:9; 0:11,24; 0:12,25; 0.16; 0:17; and 0:28) of Y. enterocolitica from pure cultures and from artificially inoculated fresh ground pork homogenate. Cefsulodin‐irgasan‐novobiocin (CIN) agar was the most effective medium for the recovery of Y. enterocolitica. However, Y. enterocolitica 0:12,25 was slightly inhibited on CIN agar. Bismuth sulfite agar, MacConkey, and MacConkey‐Tween 80 agars were acceptable; cellobiose‐arginine‐lysine, desoxycholate citrate, and Salmonella‐Shigella agars were the least effective media.
