Product Description
Drigalski Selective Agar is a specialized microbiological medium formulated to inhibit gram-positive bacteria while promoting the growth of gram-negative enteric pathogens like Salmonella and Shigella. This agar is widely used in clinical and research laboratories for diagnostic purposes, ensuring accurate identification of pathogens in stool samples or other specimens.
The medium contains bile salts and brilliant green, which suppress the growth of non-target organisms, while lactose and neutral red help differentiate lactose-fermenting colonies. Its selective properties make it indispensable for food safety testing, water analysis, and medical microbiology.
Whether you’re a student, researcher, or educator, Drigalski Selective Agar from Himedia (M1761) provides reliable results with consistent performance. The 500g pack size is ideal for labs with moderate to high throughput, offering cost-effective bulk usage without compromising quality.

How to Use Drigalski Selective Agar
1. Preparation: Suspend 35.5g of the powder in 1 liter of distilled water. Heat to boiling to dissolve completely, then sterilize by autoclaving at 121°C for 15 minutes.
2. Inoculation: Pour the cooled medium into sterile Petri dishes. Streak or spread the sample onto the agar surface.
3. Incubation: Invert the plates and incubate at 35-37°C for 18-24 hours.
4. Interpretation: Observe for characteristic colony morphology. Salmonella and Shigella typically appear as colorless or pale colonies, while lactose-fermenters (e.g., E. coli) produce pink/red colonies.
Key Applications
Drigalski Selective Agar is essential for:
- Clinical microbiology labs isolating enteric pathogens.
- Food and water testing for Salmonella contamination.
- Educational institutions teaching bacterial identification techniques.
- Research projects studying gram-negative bacterial behavior.
Storage and Handling
Store the powder at room temperature (15-30°C) in a dry place, away from direct sunlight. Prepared agar plates should be stored at 2-8°C and used within the recommended shelf life. Always follow standard microbiological safety protocols when handling.
