Eosin Methylene Blue Agar for Rapid Direct Count of E. Coli

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 Effect of Concentration of Dyes on Differentiation of Enteric Bacteria on Eosin-Methylene-Blue Agar.

Presumptive identification of Candida kefyr on levine formulation of eosin methylene blue agar.

Three hundred thirty-one yeast and yeast-like isolates were cultivated on eosin methylene blue agar. While the sensitivity rate for Candida kefyr isolates producing a metallic green sheen was 81.8%, the high positive predictive value (100%) for yeast isolates with this phenotype belonging to C. kefyr suggests that these isolates can be presumptively identified as C. kefyr.

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...

Observations on the Differentiation of Bact. Coli and Bact. Ærogenes on Levine's Simplified Eosin-Methylene-Blue-Agar as Applied to the Bacteriology of Water in Bengal

Escherich originally observed the occurrence of two tj'pes of lactose-fermenting intestinal bacteria which are widely distributed in water and soil. One type Bact. coli was chiefly an inhabitant of the mammalian intestines and was thus regarded as the ' microbe of indication ' of fa3cal pollution of water and the other type Bact. cerogenes was rare in human faeces but constituted the predominat...
