  • 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.

  • BM0381

    Saline (0.9%)

    Universal Isotonic Saline Solution.
  • A medium for the selective enrichment of Salmonella spp from both clinical and food samples.  It is a buffered Lactose Peptone Broth to which Sodium Biselenite is added as the selective agent. Subcultures should be made from the top 1/3 of the broth after not more than 24 hours incubation as after this time there is a loss of selectivity.
  • This medium can be used as a screening method for the differentiation of Enterobacteriaceae based on the ability of some species to utilise citrate as a sole source of carbon. It is often used as a screening test for Klebsiella pneumoniae (Positive reaction) while Escherichia coli is negative. Other uses included distinguishing between species of citrate positive Salmonellae (e.g. Salmonella enteritidis) and those that are negative (e.g. Salmonella typhi and Salmonella paratyphi A). The medium is inoculated by stabbing the organism (in pure culture) into the medium. A positive result produces a change of colour from green to bright blue and a negative reaction leaves the colour unchanged.

  • This medium is utilised for the transportation and cryopreservation of Streptococcus pneumoniae & Neisseria meningitidis isolates.
  • This is an egg-based medium for the isolation and presumptive identification of Mycobacterium spp particularly Mycobacterium bovis. This medium is used primarily in the veterinarian sector. The medium is based on the original formulation of Lowenstein that was subsequently modified by Jensen, the medium contains pyruvate and egg which provide the required protein and fatty acids. It differs from Lowenstein-Jensen Medium in that Sodium Pyruvate has replaced the Glycerol, which has been demonstrated to be inhibitory to some species, particularly M.bovis. The coagulation of the egg albumin during preparation also provides a solid surface for inoculation purposes. Malachite green is incorporated into the medium to inhibit contaminating organisms other than the mycobacteria that may still be present in the specimen after decontamination. Lowenstein-Jensen slopes should be inoculated with pre-treated specimens and incubated at 35-37°C for 8 weeks in 5-10% CO2. Container caps should be left loose for the first week of incubation to allow for circulation of the carbon dioxide as this will help to stimulate growth. Caps should then be tightened to prevent any dehydration of the medium.
  • This product may be used as an alternative pre-treatment solution to lessen the background flora of samples before the testing for Mycobacteria species. This reagent should only be used for samples that routinely produce contaminated cultures after processing with an alkaline digestant.
  • This buffer is intended primarily for use as a neutralising agent following treatment with alkaline compounds during the decontamination and homogenisation process of Sputum specimens prior to inoculation onto appropriate culture media for the isolation of Mycobacterium spp.
  • A nutritious broth medium formulated by Todd and Hewitt for the production of antigenic streptococcal haemolysin. The broth is also used to cultivate streptococci prior to serological grouping. Normally the use of fermentable sugars in the broth would inactivate the haemolysin due to acid production. This is prevented by the use of buffers to maintain the pH in this broth.
  • This medium is based on the formula described by Kupferburg, Johnson and Sprince for the selective isolation of Trichomonas spp. The medium is selective due to the inclusion of the broad spectrum antibiotic, chloramphenicol, to inhibit a wide range of Gram-positive and Gram-negative bacterial species. This medium does not contain an antifungal agent and Candida spp. will not be suppressed. However, the growth of Candida spp. does not interfere with that of Trichomonas spp. The inclusion of methylene blue as a redox indicator allows for the visualisation of any significant oxygen diffusion in the medium. Cultures may be examined microscopically after 48 hours incubation at 37°C for the presence of flagellate protozoans. If a negative result is obtained then the culture may be re-incubated for a further 72 hours.
  • This medium is based on the formula described by Kupferburg, Johnson and Sprince for the selective isolation of Trichomonas spp. The medium is selective due to the inclusion of two selective agents namely, Chloramphenicol and Nystatin, to inhibit a wide range of both Gram-positive and Gram-negative bacterial species as well as yeasts and fungi. The inclusion of methylene blue as a redox indicator allows for the visualisation of any significant oxygen diffusion in the medium. Cultures may be examined microscopically after 48 hours incubation at 37°C for the presence of flagellate protozoans. If a negative result is obtained then the culture may be re-incubated for a further 72 hours.
  • This is a medium that can be used to differentiate between some of the Enterobacteriacae on the basis of four reactions, fermentation of Lactose, Glucose and Sucrose and the production of H2S. For use the medium is inoculated using a pure culture of the test organism which should be smeared onto the surface of the slope and stabbed into the butt of the medium. For details of the many reactions that may arise during the use of this medium reference should be made to one of the many standard textbooks.
  • This is a plate count agar originally suggested by the American Public Health Association for the estimation of total viable counts in food and dairy products.
  • Tryptone Soya Broth (Modified) with Novobiocin (20mg/L) This is a selective enrichment broth for the isolation of Escherichia coli 0157, primarily from food and food products, and is capable of detecting the organisms even when they are present in small numbers. It is also increasingly being used in clinical laboratories when screening faecal samples. Based on Tryptone Soya Broth it is made selective for Escherichia coli 0157 by the addition of bile salts and Novobiocin and is also buffered to maintain the pH during incubation. This medium is generally used in conjunction with selective agar subculture (e.g. Sorbitol MacConkey Agar with Cefixime Tellurite – (CT-SMAC)).
  • A general purpose broth suitable for the cultivation of most micro-organisms including many fastidious organisms and fungi. It is recommended by the United States Pharmacopoeia for sterility testing of many pharmaceutical products.
  • Tryptone Water is an alternative medium to Peptone Water and more reliable for the testing of Indole production. The medium has a high content of Tryptophan that many organisms, particularly coliforms, break down to form Indole. After incubation add a few drops of Indole reagent to determine the Indole reaction  (Red colour is Positive).
  • Based on Christensen’s Medium this medium is generally used to detect rapid urease activity of Proteus spp although it can be used to detect urease activity of other Enterobacteriaceae. When used for the later purpose it is necessary to increase the incubation time to as long as 48 hours.
  • BM0460

    Urea Broth

    A modification of Christensen’s Medium by Maslen this medium is generally used to detect rapid Urease activity of Proteus spp although it can be used to detect Urease activity of other Enterobacteriaceae including Urease producing Salmonella and Shigella. Unlike Christensen’s Medium when used for the later purpose it is not necessary to increase the incubation time.
