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

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.
