Chemically Defined Antimicrobial Susceptibility Test Medium for Pseudomonas aeruginosa

Antimicrobial susceptibility of imipenem-resistant Pseudomonas aeruginosa.

Chemically Defined Medium

CHAMBERLAIN, ROBERT E. (The National Drug Co., Swiftwater, Pa.). Evaluation of live tularemia vaccine prepared in a chemically defined medium. Appl. Microbiol. 13:232-235. 1965.-A chemically defined medium was prepared which adequately supported growth of a vaccine strain of Pasteurella tularensis. This medium differed from those previously described in: (i) concentration of components, (ii) a ...

Rapid colorimetric assay for antimicrobial susceptibility testing of Pseudomonas aeruginosa.

A colorimetric assay based on the reduction of a tetrazolium salt [2,3-bis[2-methyloxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxanilide (XTT)] for rapidly determining the susceptibility of Pseudomonas aeruginosa isolates to bactericidal antibiotics is described. There was excellent agreement between the tobramycin and ofloxacin MICs determined after 5 h using the XTT assay and after 18 h u...

Chemically defined medium for Rothia dentocariosa.

A chemically defined medium for Rothia dentocariosa has been established. All strains tested, including the type strain, grew well in this medium. Rothia strains had a generation time of 3.5 to 4.0 h, with a yield of 62 mg (dry weight) per 100 ml after 72 h of growth in the chemically defined medium.

Chemically Defined Medium for Growth Streptococcus Pyogenes.

Mickelson, M. N. (National Animal Disease Laboratory, Ames, Iowa). Chemically defined medium for growth of Streptococcus pyogenes. J. Bacteriol. 88:158-164. 1964.-Three strains of group A hemolytic streptococci representing three serological types were serially subcultured for an extended period (100 or more transfers) in a peptide-free and protein-free culture medium. An amino acid assay mediu...
