This is a selective enrichment broth for the isolation of Salmonellae spp. primarily from food and food product samples and conforms to the requirements as described in ISO 6579:2002. It can however be used in other areas including for clinical and environmental specimens. Salmonella reduce Tetrathionate and will proliferate in the medium whilst most other enteric organisms are inhibited. Unlike the older traditional Tetrathionate Broth the addition of Novobiocin (40mg/L) improves the inhibition of Proteus spp. This complete medium already includes the 2% Iodine solution that is traditionally added immediately before use. NB: As this is an opaque medium turbidity cannot be used as an indication of growth. -
BM0550 Nutrient Broth is a basic general-purpose medium suitable for use in the cultivation of the less fastidious organisms. Nutrient broth is based on the recipe for Nutrient Agar, which was first described by the American Public Health Association (APHA) in 1917 as a medium to cultivate a wide variety of organisms. Although, a basic general-purpose medium, this medium can be enriched with other ingredients such as blood, serum, sodium chloride, sugars, etc., for special purposes. -
Based on Nutrient Broth with an additional 2.5% Sodium Chloride this medium is suitable for use in the investigation of outbreaks involving Staphylococcus aureus especially MRSA. The additional Sodium Chloride inhibits most other organisms allowing the staphylococci to multiply freely even if present in small numbers. The medium is generally used as an enrichment medium in conjunction with subculture onto selective solid media as described in PHE SMI B29 issue No.6. -
Based on Nutrient Broth with an additional 6.0% Sodium Chloride (Total Sodium Chloride content = 6.5%) this medium is suitable for use in the investigation of outbreaks involving Staphylococcus aureus including MRSA. The additional Sodium Chloride inhibits most other organisms allowing the staphylococci to multiply freely even if present in small numbers. The medium is generally used as an enrichment medium in conjunction with subculture onto selective solid media. -
Based on Nutrient Broth with an additional 6.5% Sodium Chloride (Total Sodium Chloride content = 7%) this medium is suitable for use in the investigation of outbreaks involving Staphylococcus aureus including MRSA. The additional Sodium Chloride inhibits most other organisms allowing the staphylococci to multiply freely even if present in small numbers. The medium is generally used as an enrichment medium in conjunction with subculture onto selective solid media. -
This is an aqueous solution of Oxalic acid (3%) suitable for use in the digestion and neutralisation of Sputum that may be contaminated with Pseudomonas like organisms prior to culture. -
This is an aqueous solution of Oxalic acid (5%) suitable for use in the digestion and neutralisation of Sputum that may be contaminated with Pseudomonas like organisms prior to culture. -
A general-purpose medium that can be used as a base for carbohydrate fermentation media. It has a high level of Tryptone and is therefore also suitable for use in Indole testing.
