Drug Sensitivity Testing demonstration by Dr.Rashid Iqbal MBBS MD

Описание: In this practical video, we demonstrate Drug Sensitivity Testing (DST) step-by-step with proper laboratory technique and interpretation.

Drug sensitivity testing is an essential microbiology procedure used to determine the susceptibility of bacteria to antimicrobial agents. It plays a crucial role in selecting appropriate antibiotic therapy and combating antimicrobial resistance.

In this video, we cover:

• Principle of Drug Sensitivity Testing
• Indications and clinical significance
• Kirby–Bauer disc diffusion method
• Required materials and media (Mueller-Hinton agar)
• Inoculum preparation and McFarland standard
• Placement of antibiotic discs
• Incubation procedure
• Measurement of zone of inhibition
• Interpretation (Sensitive, Intermediate, Resistant)
• Factors affecting results
• Clinical correlation

This video is useful for:
MBBS students | BDS students | Nursing students | Microbiology practical exams | OSCE | Laboratory technicians

Understanding DST is essential for rational antibiotic therapy and prevention of drug resistance.
