Isolation of Shigellae. 8. Comparison of xylose lysine deoxycholate agar, hektoen enteric agar, Salmonella-Shigella agar, and eosin methylene blue agar with stool specimens.

Abstract

Two enrichment broths and four plating media were compared for efficiency of detection of enteric pathogens from 1,597 stool specimens. Of 170 salmonellae isolated from the composite of all methods, direct streaking yielded but 54%, whereas enrichment in gram-negative broth found 87% and Selenite-F broth 97%. By contrast, gram-negative broth produced 100… (More)
