Yersinia enterocolitica selective enrichment medium and preparation method thereof

The invention relates to a yersinia enterocolitica selective enrichment medium. The medium comprises a combined nutritional agent and a combined bacteriostatic agent, the combined nutritional agent comprises casein tryptone, sorbitol, cane sugar, ornithine and sodium chloride, and the combined bacteriostatic agent comprises bile salt, sodium dodecyl sulfate, cephalosporin and novobiocin. According to the yersinia enterocolitica selective enrichment medium and a preparation method thereof, the combined nutritional agent is contained, so that growth of yersinia enterocolitica can be effectively promoted; the combined bacteriostatic agent is contained, can effectively inhibit the growth of gram-positive bacteria and inhibit the growth of the gram-negative bacteria such as escherichia coli, and has no influence on the growth of the yersinia enterocolitica. The medium can realize selective enrichment culture of the yersinia enterocolitica in a sample, optimizes the detection steps of a traditional culture method,
