Eosin Methyl-Green Sulfite Agar: A Modification of Levine's E.M.B. Agar

Eosin methyl-green sulfite agar; a modification of Levine's E.M.B. agar.

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

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% of the 17 shigellae, Selenite-F broth b...

Atypical reactions of Escherichia coli on eosin methylene blue agar.

Evidence is presented that atypical reactions of Escherichia coli on eosin methylene blue agar are due to variations in pH in localized areas of the medium.

The Introduction of Agar-agar into Bacteriology.

Among fundamental developments in bacteriology the elaboration of solid culture substrates will always hold first place. With the introduction of a method for isolating micro6rganisms and growing them in pure culture, bacteriologists possessed the means for studying what Ferdinand Cohn (1872) called "Die kleinsten lebenden Wesen." Credit for the discovery of the solid medium technique is common...

undulosa Using a Modification of Wilbrink's Agar Medium'

Wilbrink' s-boric acid-cephalexin agar medium (WBC) was developed and tested for iso­ lating Xalllh omonas campeslris pv. IIndulosa, the causal agent of bacterial leaf streak of wheat or black chaff. from seed . WBC medium is Wilbrink's medium that has been modified by adding 0.75 gil of boric acid and 10 mg/l of cephalexin. Compared to the standard Wilbrink's medium, average plating efficiency...
