The efficacy of eight routine enteric agars for supporting the growth of 32 strains of Aeromonas spp. (17 A. hydrophila strains, 8 A. sobria strains, and 7 A. caviae strains) was investigated. The plating efficiency of Aeromonas spp. on these media varied greatly (range, 0 to 100%), as did their colony size when compared with that on noninhibitory medium (5% sheep blood agar). Plating efficiency on seven of these eight media appeared to be strain- and not species dependent. Overall, eosin-methylene blue and Hektoen enteric agars showed low plating efficiencies for A. hydrophila, whereas both A. sobria and A. caviae were severely inhibited on brilliant green agar. When all these species are considered collectively, deoxycholate, MacConkey, and xylose lysine deoxycholate appeared to be the most satisfactory routine agars for Aeromonas spp. recovery when used in conjunction with blood agar.
研究了八种常规肠道琼脂对32株气单胞菌属细菌（17株嗜水气单胞菌、8株温和气单胞菌和7株豚鼠气单胞菌）生长的支持效果。气单胞菌属细菌在这些培养基上的平板接种效率差异很大（范围为0至100%），与在非抑制性培养基（5%羊血琼脂）上相比，其菌落大小也有差异。这八种培养基中的七种的平板接种效率似乎取决于菌株而非菌种。总体而言，伊红美蓝琼脂和赫氏肠道琼脂对嗜水气单胞菌的平板接种效率较低，而温和气单胞菌和豚鼠气单胞菌在亮绿琼脂上均受到严重抑制。当将所有这些菌种综合考虑时，脱氧胆酸盐琼脂、麦康凯琼脂和木糖赖氨酸脱氧胆酸盐琼脂与血琼脂联合使用时，似乎是用于气单胞菌属细菌分离的最理想常规琼脂。
