Abstract
Numerous selective media, available commercially, act by suppressing “normal” bacterial inhabitants of the intestine while permitting the growth of so-called pathogenic representatives of the family
Enterobacteriaceae
. This investigation attempts to evaluate the action of
Salmonella-Shigella
(SS) agar, xylose lysine desoxycholate (XLD) agar, and hektoen enteric (HE) agar. Salmonellae and shigellae, isolated from clinical material, were mixed in various ratios with escherichiae,
Klebsiella-Enterobacter-Serratia
group bacteria, and members of the tribe
Proteeae
, also of clinical origin. Several of the mixtures were plated in multiple dilutions on the three media. Stools in preservative were also used for evaluation of the media after the addition of definite numbers of the pathogenic bacteria. Results indicate that SS agar suppresses the shigellae along with the autochthonous members of
Enterobacteriaceae
. XLD and HE agars readily permit the recovery of shigellae as well as salmonellae. This recovery is not obscured by the higher yield of other species obtained with these media.
