Differential selective medium for enteropathogenic bacteria, especially salmonella and shigella. The composition of the medium allows the differentiation of colonies rapidly fermenting one of the 3 sugars (turning from blue to salmon-red) and/or producing H2S (black centre).

Used for the isolation and presumptive identification of Pseudomonas aeruginosa. Cetrimide is a quaternary ammonium that inhibits the growth of most other bacterial species. Pseudomonas aeruginosa stains this medium blue-green by producing pyocyanin.
Used for the isolation of pathogenic Staphylococci which give yellow colonies by fermentation of mannitol and phenol red virage. Its high sodium chloride content inhibits the growth of most other species.
Used for the presumptive identification of Enterobacteriaceae based on the fermentation of glucose, lactose, sucrose and the production of gas and H2S. For the detection of Salmonella in food and dairy products.
Used for the culture of lactobacillus. The selectivity of the medium is only ensured by its pH. It is advisable to use a more selective medium for heavily contaminated samples.
Differential medium to guide the identification of lactose-fermenting and non-lactose-fermenting Enterobacteriaceae. It is recommended for the detection of escherichia coli in water, food, dairy products and pharmaceutical preparations.
A general purpose medium for the growth and isolation of a wide variety of microorganisms. It can be supplemented with 5-7% blood to determine haemolytic reactions.
Selective medium for Enterobacteriaceae and particularly for Salmonella and Shigella. It allows an orientation of the identification of enterobacteria based on 3 criteria: fermentation of sugars, decarboxylation of lysine and production of H2S. Its use is recommended by the European and American pharmacopoeias.
Thinner commonly used for the preparation of food samples. Recommended for pre-enrichment and recovery of Salmonella from food before selective enrichment and isolation. Sodium thiosulphate neutralises oxidising compounds (chlorine and hypochlorites, iodine, hydrogen peroxide, peracetic acid, etc.). Lecithin and polysorbate (Tween® 80) neutralise quaternary ammoniums, fatty amines, amphoteric compounds, phenolic compounds and derivatives (orthophenol, phenylethanol, phenoxyethanol, triclosan), biguanides and similar compounds and alcohols. L-histidine neutralizes aldehydes.
For the isolation of pathogenic Staphylococci which give yellow colonies by fermentation of mannitol and phenol red virage. Its high sodium chloride content inhibits the growth of most other species.
Used for the isolation and enumeration of enterococci in water, foodstuffs by membrane filter technique or isolation on Petri dishes. According to ISO 11133 / ISO 7899-2.
Recommended for the investigation of Salmonella other than Salmonella typhi in foods and pharmaceuticals. It is a highly selective medium for Salmonella The high level of bright green inhibits the growth of Gram-positive and most Gram-negative bacteria. The use of this medium for the isolation of Enterobacteriaceae is not recommended. Similarly, there is little or no growth of typhoid salmonella and shigella.
Selective medium for Enterobacteriaceae and particularly for Salmonella and Shigella. It allows an orientation of the identification of enterobacteria based on 3 criteria: fermentation of sugars, decarboxylation of lysine and production of H2S.
