HiMedia SS Agar (Salmonella-Shigella Agar)

HiMedia SS Agar – Selective & Differential Medium for Salmonella and Shigella

The HiMedia SS Agar is a highly selective and differential culture medium used for the isolation of Salmonella and Shigella species from clinical and environmental samples. Manufactured by HiMedia Laboratories, this medium is widely used in microbiology laboratories for enteric pathogen detection.

What is SS Agar?

Salmonella-Shigella (SS) Agar is a specialized medium containing bile salts, brilliant green dye, and sodium citrate to inhibit Gram-positive bacteria and many Gram-negative coliforms. It also differentiates organisms based on lactose fermentation and hydrogen sulfide (H₂S) production.

Key Features of HiMedia SS Agar

1. Highly Selective Medium
Inhibits unwanted bacteria, allowing selective growth of Salmonella and Shigella species.

2. Differential Identification
Differentiates organisms based on lactose fermentation using neutral red indicator.

3. Hydrogen Sulfide Detection
Contains iron salts to detect H₂S production, forming black-centered colonies.

4. Easy Interpretation

• Salmonella: Colorless colonies with black centers (H₂S positive)
• Shigella: Colorless colonies (no H₂S)
• Lactose Fermenters: Pink/red colonies

5. Reliable and Consistent Performance
Manufactured under strict quality control standards for accurate results.

Applications of HiMedia SS Agar

• Isolation of Salmonella and Shigella
• Clinical stool sample analysis
• Food and water microbiology testing
• Public health laboratories
• Research and academic use

Benefits of HiMedia SS Agar

• Selective Isolation of enteric pathogens
• Clear Colony Differentiation
