Kirby-Bauer Disk Diffusion Testing: Standardized antimicrobial susceptibility testing of rapidly growing aerobic bacteria (e.g., Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecalis).

MIC Determination (Etest/Gradient Diffusion): Establishes minimum inhibitory concentrations for antibiotics using gradient strips on Mueller Hinton Agar.

Antibiotic Potency and QC Assays: Assesses antibiotic activity and verifies disk potencies and lot performance under CLSI guidelines.

Cultivation of Nonfastidious Bacteria: Supports growth of nonfastidious organisms for downstream susceptibility testing and research.

MRSA/MSSA and Resistance Screening: Used with cefoxitin/oxacillin disks to detect mecA-mediated resistance in Staphylococcus aureus and related species.

Clinical and Public Health Surveillance: Generates standardized AST data for antibiograms and resistance trend monitoring.

Teaching and Training: Demonstrates principles of AST and zone measurement in academic and clinical laboratories.
