Use of Eosin Methylene Blue Agar to Differentiate Escherichia Coli from Other Gram-Negative Mastitis Pathogens

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 target of daptomycin is absent from Escherichia coli and other gram-negative pathogens.

Antistaphylococcal agents commonly lack activity against Gram-negative bacteria like Escherichia coli owing to the permeability barrier presented by the outer membrane and/or the action of efflux transporters. When these intrinsic resistance mechanisms are artificially compromised, such agents almost invariably demonstrate antibacterial activity against Gram negatives. Here we show that this is...

Escherichia coli mastitis in the Dairy Bovine

Mastitis is a continuous concern for dairy producers in the US because of its economic consequences. Coliform mastitis accounts for 20-80% of acute clinical mastitis cases and includes gram-negative pathogens Escherichia coli, Klebsiella and Enterobacter species. Rapid identification of the causative organism is essential to implement a prudent treatment plan. Escherichia coli can be rapidly id...

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.
