Product Description
SS Agar (Salmonella Shigella Agar) HiMedia
SS Agar (Salmonella Shigella Agar), HiMedia Code: M108, is a classic differential, highly selective medium widely utilized in medical diagnostic laboratories, public health agencies, and food microbiology units. Specifically designed for the isolation and presumptive identification of enteric pathogenic bacilli—notably Salmonella and Shigella species—from heavily contaminated specimens such as feces, rectal swabs, and food-borne hygiene samples, it is an essential diagnostic reagent across hospital pathology departments and university microbiology faculties throughout Bangladesh.
Isolating enteric pathogens from specimens crowded with normal intestinal flora requires a specialized chemical formulation that suppresses background coliforms and Gram-positive organisms. SS Agar achieves powerful selectivity through optimized concentrations of bile salts, sodium citrate, and brilliant green dye, which collectively inhibit Gram-positive bacteria, coliforms, and swarming Proteus species. Simultaneously, it provides clear differential diagnostics via lactose fermentation and hydrogen sulfide ($H_2S$) production. Lactose-fermenting organisms produce acid that turns the neutral red indicator pink or red, whereas lactose-non-fermenters (such as pathogenic Salmonella and Shigella) form transparent, colorless colonies. Furthermore, Salmonella species producing $H_2S$ exhibit distinct colonies with black centers due to the reaction between sodium thiosulfate, ferric citrate, and hydrogen sulfide gas.
Supplied as a free-flowing, homogeneous pinkish-beige dehydrated powder, it dissolves efficiently in distilled water (typically 63.0 g/L) and is prepared by boiling without autoclaving (overheating can destroy selective agents and impair gel performance). Victor Scientific Co. supplies authentic HiMedia culture media, analytical reagents, and laboratory apparatus nationwide with batch traceability and dependable delivery across all 64 districts of Bangladesh.
✹ Key Features
Authentic HiMedia Quality (Code: M108)
Manufactured to stringent international microbiological benchmarks, ensuring consistent selective inhibition and sharp diagnostic color differentiation.
Powerful Selective System
Contains bile salts, sodium citrate, and brilliant green to heavily suppress Gram-positive bacteria, coliforms, and swarming organisms.
Clear Pathogen Differentiation
Differentiates non-lactose fermenting pathogens (colorless colonies) from lactose fermenters (pink/red colonies).
Hydrogen Sulfide ($H_2S$) Indicator Detection
Incorporates sodium thiosulfate and ferric citrate to highlight Salmonella colonies with characteristic black centers.
Convenient Preparation Ratio
Requires suspending 63.0 grams in 1,000 ml of purified distilled water, heating with frequent agitation to dissolve, without autoclaving.
Moisture-Resistant HDPE Packaging
Packaged in a 500-gram hermetically sealed container designed to safeguard the dehydrated powder against ambient humidity and degradation.
✹ Applications
- Clinical diagnostic isolation of Salmonella and Shigella species from stool specimens and rectal swabs
- Food and dairy product safety testing for enteric food-borne pathogen contamination
- Public health water quality surveillance and sewage effluent monitoring for enteric disease vectors

Frequently Asked Questions (FAQ)
A1
The price of SS Agar HiMedia M108 (500g pack) in Bangladesh typically ranges between BDT 8,000 and BDT 11,000, depending on import batches and foreign exchange rates. Contact Victor Scientific Co. directly for exact institutional quotes and bulk discounts.
Q2
Should SS Agar be autoclaved during preparation?
A2
No! Unlike most nutrient agars, SS Agar must not be autoclaved. The medium contains heat-sensitive selective agents and sugars that degrade under steam sterilization pressure. It is prepared by suspending the powder in water, bringing it to a boil with frequent agitation to dissolve completely, and then cooling it directly to 45°C–50°C before pouring.
Q3
How do Salmonella and Shigella colonies appear on SS Agar?
A3
Both Salmonella and Shigella are non-lactose fermenters, producing translucent, colorless colonies. However, most Salmonella strains produce hydrogen sulfide ($H_2S$), which results in colonies featuring distinct black centers, whereas Shigella colonies remain entirely colorless.
Q4
What is the final pH of prepared SS Agar?
A4
The standardized final pH of the prepared medium is 7.0 ± 0.2 at 25°C.
Q5
Does Victor Scientific Co. deliver culture media safely across Bangladesh?
A5
Yes, Victor Scientific Co. packages all culture media bottles in protective cushioning and moisture-barrier cartons, ensuring rapid courier delivery to all 64 districts in Bangladesh—including Chattogram, Rajshahi, Khulna, and Sylhet—within 24 to 48 hours.
