Abstract
We studied nine solid and two liquid media for their suitability to select Aeromonas and Plesiomonas spp. from human stools, using artificially contaminated samples as well as 254 samples from outpatients with and without diarrhea. Media with optimal sensitivity and specificity for Aeromonas spp. were alkaline peptone-water, Trypticase soy broth with ampicillin, inositol-brilliant green-bile salts agar, dextrin-fuchsin-sulfite agar, xylose-sodium desoxycholate-citrate agar, and Pril-xylose-ampicillin agar. For Plesiomonas sp., alkaline peptone-water and inositol-brilliant green-bile salts agar were optimal. Four strains of Aeromonas spp. were detected in patient samples with these media.
