Polymyxin-coagulase-mannitol-agar. I. A selective isolation medium for coagulase-positive Staphylococci.
A selective, differential plating medium was developed for the isolation and identification of coagulase-positive and mannitol-fermenting staphylococci. Coagulase produced by growing Staphylococcus aureus caused an opaque zone of fibrin to form around each colony. Several strains of S. aureus produced a visible coagulase reaction by 8 hr, and all strains gave a positive reaction before 12 hr. M...
متن کاملComparison of acetate differential agar with sellers citrate-mannitol-agar.
A total of 245 isolates of Escherichia coli (paracolons) were employed in comparing the use of acetate differential agar (ADA) with the simple test described by Sellers to eliminate these organisms from consideration as enteric pathogens. At 18 hr after the media were inoculated, 83% of the isolates produced a positive citrate reaction on Sellers citrate-mannitol-agar (SCM) and 7% gave a positi...
متن کاملCharacteristics of coagulase positive and coagulase negative staphylococci in serum-soft agar.
Preliminary experiments revealed that coagulase positive staphylococci could be distinguished culturallv from coagulase negative staphylococci in a soft agar medium containing a small amount of normal human or rabbit plasma. In a medium of suitably low viscosity, staphylococci produce elongated diffuse feathery colonies. When coagulable plasma is incorporated in such a medium, the colonies of c...
متن کاملA new selective, differential agar medium for isolation of Vibrio cholerae O1: PMT (polymyxin-mannose-tellurite) agar.
A new selective and differential agar medium, polymyxin-mannose-tellurite (PMT) agar was devised to differentiate easily colonies of Vibrio cholerae O1 from those of V. cholerae non-O1. The differentiation between colonies of the two vibrios is based on mannose-fermentation. Colonies of V. cholerae O1 on the agar are agglutinated with O1 antiserum of V. cholerae much more easily than those on t...
متن کاملThe Reliability of Bromthymol-Blue Lactose Agar and Bacto Phenol-Red Mannitol Agar for the Isolation of Pathogenic Staphylococci.
Since 1937 more than 7,000 samples have been tested routinely in this laboratory on Bacto bromthymol-blue lactose agar (Chapman et at., 1937) and Bacto phenol-red mannitol agar (Chapman, Lieb, and Curcio, 1938) for the isolation of plasma-coagulating staphylococci. Althpugh our impressions of the results obtained have been favorable, the publication of an adverse (but unsubstantiated) opinion b...
