A total of 69 dyes were incorporated separately at different concentrations into an agar medium for evaluation of their effects on the quantitative recovery of five serotypes of Yersinia enterocolitica. One strain of Pseudomonas aeruginosa and one strain of Bacillus cereus were included for comparative purposes. Certain dyes were evaluated further for their selective properties with five additional serotypes of Y. enterocolitica, three strains of P. aeruginosa, and two of Engerobacter spp. Metanil yellow was the only dye which was tolerated bettr by Y. enterocolitica than by P. aeruginosa. Dye sensitivity was variable amond strains of the same serotype of Y. enterocolitica. In general, Y. enterocolitica showed a tolerance to dyes greater than that of gram-positive bacteria and similar to that of other gram-negative bacteria.
总共69种染料分别以不同浓度加入琼脂培养基中，以评估它们对5种血清型小肠结肠炎耶尔森菌定量回收的影响。为作比较，还加入了1株铜绿假单胞菌和1株蜡样芽孢杆菌。部分染料还用另外5种血清型的小肠结肠炎耶尔森菌、3株铜绿假单胞菌和2株肠杆菌属细菌进一步评估其选择性。金莲橙黄是唯一一种小肠结肠炎耶尔森菌比铜绿假单胞菌耐受性更好的染料。同一血清型的小肠结肠炎耶尔森菌不同菌株对染料的敏感性存在差异。总体而言，小肠结肠炎耶尔森菌对染料的耐受性高于革兰氏阳性菌，与其他革兰氏阴性菌相似。
