  • This is an egg-based medium for the isolation and presumptive identification of Mycobacterium spp., particularly Mycobacterium tuberculosis. Designed for use with NaOH treated samples which have sterile distilled water added at the end of the designated treatment time to "dilute" the effect of NaOH. NB: this media will NOT isolate M.bovis which requires the addition of pyruvate as a growth supplement. This is normally overcome by the inclusion of a pyruvate slope. Based on the original formulation of Lowenstein that was subsequently modified by Jensen, the medium contains glycerol and egg which provide the required protein and fatty acids. 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 media will isolate most common mycobacteria including M.bovis. 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.

Caps should then be tightened to prevent any dehydration of the medium.
  • Alkaline Peptone Water is generally used as an enrichment medium in the isolation of Vibrio spp. from faeces. The high pH of the medium inhibits most enteric organisms for at least 24 hours. The medium is heavily inoculated with faeces and after not more than 8 hours incubation a loopful from the top of the medium is sub cultured onto TCBS Agar. This enrichment medium is also used for food and water testing.
  • This is a variation on sterile isotonic Saline which is suitable for use in preparation of food samples and/or as a rinse during examination of equipment etc. prior to culture. It can also be used as a general purpose diluent in many areas of the laboratory. The addition of glass beads will allow dense material to be broken down and aid the isolation of any bacteria that may be present in “clumps”.
  • Bile Aesculin Medium is generally used for the differentiation and presumptive identification of Group D streptococci (enterococci). Enterococci hydrolyse aesculin forming, amongst other products, aesculetin which in turn combines with Ferric ammonium citrate producing a dark brown or black complex. The presence of Bile salts in the medium inhibits gram positive organisms other than enterococci. The medium can also be used for the presumptive identification of certain organisms within the Enterobacteriaceae group such as Klebsiella spp., Enterobacter spp., etc.
  • This is a very nutritious general-purpose medium suitable for the isolation of most organisms including many fastidious anaerobes. It is particularly recommended for streptococci and neisseria.
  • A very nutritious isotonic general purpose medium with a low concentration of Glucose to stimulate early growth, Brain Heart Infusion Broth is suitable for the isolation of most micro-organisms including many fastidious organisms and, with enrichment as appropriate, is suitable as a base for blood culture medium. A phosphate buffer is incorporated to help neutralise any acids produced as a result of Glucose utilisation and thus maintain viability of the organisms. NB: Organisms that produce large amounts of acid in the medium may overwhelm the buffering system and as a result ‘auto-sterilise’ the culture.
  • An enriched general purpose broth enriched with 10% defibrinated horse blood for the isolation of fastidious organisms.
  • A very nutritious isotonic general-purpose medium with a low concentration of Glucose to stimulate early growth, Brain Heart Infusion Broth is suitable for the isolation of most micro-organisms including many fastidious organisms and, with enrichment as appropriate, is suitable as a base for blood culture medium. A phosphate buffer is incorporated to help neutralise any acids produced as a result of Glucose utilisation and thus maintain viability of the organisms. This particular formulation also has added Glycerol to act as cryopreservative if the medium is used for the long term frozen storage of microorganisms. NB: Organisms that produce large amounts of acid in the medium may overwhelm the buffering system and as a result ‘auto-sterilise’ the culture.
  • An enriched general purpose broth being an isotonic medium with Tryptose providing a wide range of substrates. The medium is further enriched with 10% horse serum for more fastidious organisms and as an enrichment broth.
  • Brucella Broth was developed to cultivate Brucella spp. from a wide variety of clinical samples but it is also widely used as a general enrichment broth for both fastidious and non-fastidious organisms.
  • This is one of a number of selective enrichment broths that can be used in the isolation of Campylobacter spp from clinical, food and environmental specimens and contains nutrients to aid in the resuscitation of damaged organisms. The medium is enriched with Lysed Horse Blood and made selective by the inclusion of Vancomycin, Cefoperazone, Trimethoprim and Amphotericin B. Following incubation at 37ºC the broth is usually sub-cultured onto an appropriate solid Campylobacter medium.
  • The principle use for this product is in the testing of disinfectants and antiseptics. In 1989, the European Committee for Standardisation (CEN) set up a technical committee to produce harmonised test methods for disinfectants and antiseptics. The CEN standards provide a useful basis for disinfectant validation, and although alternative methods could be used for assessing disinfectant efficacy, following the same basic methods allows not only direct comparison between products but also comparison across various different laboratories. The adaptability of the methods - numerous validation studies based on the CEN methods have been accepted by both the European and US regulatory authorities - allows end- users to customise the methods to their specific requirements. Lecithin and polysorbate 80 (Tween 80) inactivate surface disinfectants (lecithin neutralises quaternary ammonium compounds and Tween 80 neutralises phenols, formalin, hexachlorophene and in combination with the lecithin ethanol). L-histidine, in combination with lecithin and Tween 80, neutralises aldehydes and formaldehyde generating agents. Sodium thiosulphate neutralises iodine and chlorine.

    Columbia Agar

    Columbia Agar is a nutritious general-purpose basal medium capable of supporting the growth of most micro-organisms, including many fastidious organisms that do not require blood. However when further enriched with Sterile Blood, which can be “chocolated” if required, the medium is generally used for the isolation of most clinically significant pathogens.  The medium can be made selective for various groups of organisms by the addition of a range of antimicrobial supplements. This formulation complies with the Harmonized USP/EP/JP.
  • A very nutritious general-purpose medium based on Columbia Agar Base enriched with 7% Horse Blood, suitable for the cultivation and maintenance of most organisms including many fastidious anaerobes of clinical significance.
  • A highly nutritious medium enriched with Horse Blood, where the blood has been ‘chocolated’ by heating the medium to 60°C. Suitable for the cultivation of most pathogens including many fastidious organisms and is particularly suitable for Haemophilus and Neisseria spp.
  • Prepared from Minced Meat granules overlaid with Fastidious Anaerobe Broth this medium is suitable for the recovery, isolation and storage of the most fastidious anaerobes and is possibly one of the best variations of Cooked Meat Medium available. Fastidious Anaerobe Broth is designed for optimum growth of all anaerobes, with the growth factors Vitamin K, Haemin and L-Cysteine included in the medium to assist those anaerobes that require them. L-Cysteine together with Sodium Thioglycollate is also present to reduce the ph of the medium and a small amount of Agar to reduce the absorption of Oxygen and convection currents. The redox indicator Resazurin is also present.  If immediately before use a narrow band of reddish/purple is apparent at the surface of the broth this does not indicate that the medium is unsuitable for use. This is due to the action of oxygen on the redox indicator and the medium should be placed in a boiling water bath, with the cap loosened, for about 15 minutes to remove dissolved oxygen. Immediately on removal from the water bath the cap should be tightened and the medium allowed to cool without agitation.
  • Prepared from Minced Meat granules overlaid with Brain Heart Infusion Broth this medium is suitable for recovery, isolation and storage of the most fastidious anaerobes as well as many aerobes.
  • This is a defined medium primarily for the cultivation of fungi and bacteria that are capable of utilising Sodium Nitrate as their sole source of Nitrogen. If made more acidic by adjusting to pH 3.5 it can also be used for isolation of yeasts. It has also been used for the identification of Candida albicans by chlamydospore production.
  • All E&O products are for in vitro use only. E&O products are intended only for use by qualified professionals who will safely handle and dispose of products they receive. All biologically derived materials (e.g. blood, sera) should be handled as if a potential biohazard. E&O media that contain antibiotics should be handled with care. Chemical resistant gloves, eye protection and laboratory coat should be worn.
  • Legionellae are more resistant to lower pH and brief exposure to higher temperatures than many other freshwater bacteria. For some water samples with high concentrations of bacteria, it is necessary to use a selective procedure to reduce the number of non-Legionella bacteria before culture. Acid treatment and heating of samples are routinely used for this purpose and to aid antigen extraction. The use of this buffer is recommended in the International Standard ISO 11731-2 "Water quality-Detection and enumeration of Legionella" for this purpose.
  •  For in vitro diagnostic use. BM1682 Faecal Transport Solution is recommended for the transport of clinical specimens, especially those associated with enteric pathogens (1). This formulation allows for transport at chilled or ambient temperatures.

    BM1682 Faecal Transport Solution is a modified Cary Blair Transport Medium (2), designed for the transportation and preservation of clinical specimens, primarily stool and rectal swabs. The product is designed to maintain the viability of enteric bacterial pathogens during transport and subsequent storage at chilled or ambient temperatures.

    Faecal Transport Solution is an isotonic, buffered, and nonnutritive medium with a carefully balanced composition. It includes agar to help reduce oxygen diffusion, sodium thioglycolate to impede oxidation, and disodium phosphate to help maintain pH. The relatively high pH of the medium helps to minimises overgrowth of non-target organisms and prevent acid formation in the specimen. References
