Abstract
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.
