Kirby–Bauer Disk Diffusion AST: Standardized 3.8% Mueller–Hinton Agar supports reliable antibiotic zone-of-inhibition testing.

MIC by Gradient Diffusion Strips: Used to determine minimum inhibitory concentrations with Etest/gradient strips.

Quality Control with Reference Strains: Routine QC of antibiotic performance using strains such as Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, and Pseudomonas aeruginosa ATCC 27853.

Nonfastidious Bacterial Cultivation: Growth and maintenance of aerobic and facultative organisms for downstream testing.

AST of Fastidious Organisms (Supplemented): When supplemented with 5% sheep blood and β-NAD, suitable for testing Streptococcus pneumoniae and Haemophilus influenzae.

Trimethoprim/Sulfonamide Testing: Low thymidine/thymine content enables accurate susceptibility testing for these agents in Enterobacterales and other pathogens.

Education and Training: Demonstrations of antibiotic susceptibility and resistance profiling in teaching labs.

Antimicrobial Diffusion Studies: Evaluation of diffusion characteristics and pigment production with organisms like Pseudomonas aeruginosa.
