The reduction in spore production is significantly negatively correlated with antibiotic production (F 1,29 = 26.58, r 2 = 0.478, P < 0.001) (fig. S5A). This provides evidence that antibiotic production is costly to S. coelicolor and that there is a direct trade-off between antibiotic production and reproductive capacity, possibly because ...

Diffusion testing works by placing an antibiotic disc onto an agar plate containing bacteria. The plate is incubated for up to 24 hours and during this time, the antibiotic diffuses throughout the plate, forming a concentration gradient surrounding the disc. 64 As the antibiotic concentration decreases, bacteria are more likely to grow. The …

Overview on Strategies and Assays for Antibiotic Discovery
The "direct" agar diffusion assay is primary used to screen potential antibiotic producers such as actinomycetes [ 18, 19] by their direct exposure to an indicator strain (also called test strain) on solid medium. First, the producer is spotted and incubated at optimal conditions (for actinomycetes, 28–37 °C, 5–14 days).

About the CDS Test | The CDS Antibiotic Susceptibility Test
The Disc potencies. In the development of the CDS test, the potencies of antibiotics discs were carefully selected to ensure two results. The first was that there was a uniform cut-off zone size between resistant and susceptible strains. Secondly, that the cut-off point should lie on the optimal part of the diffusion curve for separation.
