MAST Hektoen Enteric Agar – 500g

MAST Hektoen Enteric Agar 500g is a dehydrated selective and differential culture medium designed for the isolation and differentiation of Salmonella spp. and Shigella spp. from specimens containing mixed intestinal flora. The medium incorporates bile salts and indicator systems to suppress much of the accompanying intestinal flora while supporting recovery of enteric pathogens. Sodium thiosulphate and ferric ammonium citrate also allow detection of hydrogen sulphide-producing organisms, helping differentiate Salmonella from other enteric bacteria. Key Features - Selective and differential medium for Salmonella and Shigella - Helps suppress competing intestinal flora - Supports presumptive recognition of enteric pathogens - Detects hydrogen sulphide production - Contains lactose, sucrose and salicin for carbohydrate differentiation - Supplied as dehydrated powder - 500g laboratory pack - MAST product code DM134D - Suitable for clinical, food and public-health microbiology Specification Details Product Name Hektoen Enteric Agar Brand MAST Product Code DM134D Pack Size 500g Form Dehydrated powder Medium Type Selective and differential culture medium Main Target Organisms Salmonella spp. and Shigella spp. Preparation Rate 69.8g per litre Approximate pH 7.2 Sterilization Do not autoclave Preparation Method Heat gently and boil briefly until agar dissolves Pouring Temperature Approximately 55–60°C Laboratory Area Clinical / food / public-health microbiology Intended Use In vitro laboratory use
