Selection of a reference lot of Mueller-Hinton agar.
A collaborative study was undertaken to evaluate the performance of currently marketed Mueller-Hinton agars from seven manufacturers by replicate disk diffusion tests with standard quality control strains. Identification of the manufacturers was concealed, and the resulting data were evaluated for the selection of a physical reagent standard against which the performance of future production lo...
متن کاملEvaluation of Mueller-Hinton agar for disk diffusion susceptibility tests.
Twelve lots of commercially prepared Mueller-Hinton agar from four medium manufacturers were evaluated for performance with recommended quality control organisms, medium pH, agar depth and uniformity, and characteristics of the zones of inhibition. Only 2 of 12 lots were acceptable for disk diffusion susceptibility tests. Significant problems were observed with the preparation and pouring of th...
متن کاملEffect of zinc concentration in Mueller-Hinton agar on susceptibility of Pseudomonas aeruginosa to meropenem.
The susceptibility of Pseudomonas aeruginosa to imipenem has been shown to vary according to zinc concentration in the media. MICs of imipenem for 68 unique clinical isolates of P. aeruginosa were determined in media supplemented with zinc at concentrations between 0.5 and 6.0 micrograms/ml. In agar containing up to 3 micrograms of zinc/ml, 75 to 82% of the strains were susceptible to imipenem ...
متن کاملIncidence of thymidine-dependent enterococci detected on Mueller-Hinton agar with low thymidine content.
It was observed that 10% of urine culture isolates of enterococci tested for antimicrobial susceptibility failed to grow on commercially prepared Mueller-Hinton agar with low levels of thymidine and thymine. All strains could utilize exogenous thymidine and thymine and required only low levels (0.4-microgram disk) to support growth. All thymidine-thymine-requiring strains were resistant to trim...
متن کاملEffect of storage of Mueller-Hinton agar plates on zone sizes for antimicrobial testing.
The length of time Mueller-Hinton agar plates can be stored at 4 C without affecting the size of zones of inhibition in susceptibility testing by the Bauer-Kirby method was studied. It was found that these plates can be stored for 3 weeks at 4 C without an appreciable affect on zone sizes. Storage of plates in sealed plastic bags did not alter the results significantly. The findings indicate th...
