Streptomyces inside-out: a new perspective on the bacteria …

Considering the startling effects of bldA mutations on Streptomyces colonies, it was curious to find that the global patterns of protein spots seen on two-dimensional gels were largely unaffected, many of the changes being in the proteins concerned with antibiotic production: proteins involved in the production of seven different …

About the CDS Test | The CDS Antibiotic Susceptibility Test

With most antibiotics, this lies at a point 6 mm from the edge of the antibiotic disc, so that an annular radius of 6 mm (18 mm diameter) was selected as the uniform cut-off point. The advantages of a uniform cut-off point for the majority of antibiotics are obvious in that it obviates the need for interpretative charts.
