  • CLED Agar (Bevis) A modification by Bevis of the original CLED medium of Mackey & Sandys. This formulation uses a double indicator system (Andrade’s (Acid fuchsin) and Bromothymol blue) to improve differentiation of Lactose and Non-lactose fermenting organisms. The lack of Sodium Chloride also prevents the swarming of Proteus spp.
    Details
  • This is one of a number of media available for the selective isolation of Neisseria gonorrhoeae. Based on the medium of Thayer & Martin it includes Corn Starch to absorb toxic metabolites and is buffered to maintain a neutral pH. The medium is enriched with Defibrinated Horse Blood where the blood has been ‘chocolated’ by heating the medium to 60°C and made selective by the inclusion of VCAT (Vancomycin, Colistin, Amphotericin and Trimethoprim). Vancomycin and Colistin inhibit the growth of the majority of contaminating organisms likely to be present. Trimethoprim is included to reduce the spread of Proteus spp and Amphotericin to suppress yeasts. Yeast Extract and Glucose are also added as further enrichment.

  • In recent years there has been an increase in the number of immuno-compromised patients, which has in turn led to an increased rate of infections associated with Candida species. There were 2151 reported cases of candidaemia in 2016 with C.albicans accounting for 42%, C.glabrata for 25%, C.parapsilosis for 9% and C.tropicalis for 3% of infections in England, Wales and Northern Ireland.(1) COLOREX™ Candida was formulated specifically for the detection and isolation of clinically significant Candida spp. by means of colonial colour and morphology within 48hrs. COLOREX™ Candida allows for the recognition of a minor Candida population within a mixed population as well as the pre-dominant species thereby allowing for a patient specific treatment plan at the earliest possible opportunity. Most bacterial species will be inhibited due to the inclusion of chloramphenicol. C.albicans – Green colonies C.tropicalis – Metallic blue colonies C.glabrata – Mauve to pink colonies C.krusei – Large fuzzy pink colonies Limitations Definitive identification requires additional testing of isolates (e.g. MALDI-TOF). C.glabrata and C.parapsilosis cannot be readily distinguished on this particular medium. C.dubliniensis will form dark green colonies on COLOREX™ Candida so additional testing is required to confirm presence in the specimen. C.auris isolates will grow on this medium but the colony colour may vary from white to pale purple/pink so further testing will be required to confirm identification.

  • Fastidious Anaerobe Agar (FAA) with 7% Horse Blood & Neomycin (75mg/L) Fastidious Anaerobe Agar is intended as a primary isolation medium capable of supporting most clinically significant anaerobes including fastidious organisms. The formulation is complex and includes detoxification agents (Starch & Sodium Bicarbonate) as well as growth enhancing agents (Cysteine, Arginine, Vitamin K, Sodium Succinate, Glucose and pyrophosphate) as well as Haemin to encourage pigment production in Porphyromonas melaninogenicus. Sodium Pyruvate is also included to help neutralise Hydrogen Peroxide. In this instance the medium is made more selective by the inclusion of 75mg/L of Neomycin to inhibit most enteric organisms and further enriched by the addition of 7% Horse Blood.
    Details
  • This is a selective medium for the isolation and enumeration of enterococci (Group D streptococci) primarily in food although it has found uses in other areas of bacteriology. The medium is made selective by the inclusion of Kanamycin and Sodium Azide while Aesculin and Ferric Ammonium Citrate act as the indicator system.
    Details
  • This is a medium specifically intended for sensitivity testing of Haemophilus influenzae and Haemophilus parainfluenzae. Based on Mueller Hinton Agar with added Yeast Extract the medium is enriched by the addition of Haemin and NAD (Nicotinamide Adenine Dinucleotide (V Factor)). It contains very low levels of antimicrobial antagonists that allow testing of Sulphonamides and Trimethoprim to be performed with confidence and is recommended by the Clinical and Laboratory Standards Institute (CLSI).
    Details
  • This is a selective chromogenic medium for the detection of Malassezia spp., especially M.restricta and M.globosa, in veterinary or clinical specimens. Malassezia spp. is a commensal organism in humans and animals that can cause severe dermatitis or otitis infections. The medium is supplemented with Glycerol and Tween 40 to enhance the in-vitro growth of Malassezia spp. due to the complex lipid requirements of these yeasts. Appearance and differentiation of Malassezia spp. is readily apparent by the distinctive colonial colours allowing for differentiation from Candida spp. in specimens. The inclusion of chloramphenicol ensures the inhibition of bacterial species during incubation of specimens.

  • Thiosulphate Citrate Bile Salts Sucrose (TCBS) Agar TCBS is a selective isolation medium for culture of pathogenic Vibrio spp. from clinical samples. The formulation was developed by Kobayashi, Enomoto, Skazaki and Kuwahara. This medium inhibits most enterobacteriacae for at least 24 hours. For the isolation of Vibrio spp. other than V.cholerae in environmental bacteriology, it is advisable to incubate at the lower temperature range of 20°C – 30°C. NB - It is not recommended to perform an oxidase test on any presumptive positive isolates directly from TCBS medium.
    Details
  • This is a medium for the selective isolation of Staphylococcus spp. and Streptococcus spp. primarily from clinical specimens. Based on Columbia Agar Base enriched with 7% Horse Blood the medium is made selective by the inclusion of Colistin and Nalidixic Acid to suppress the growth of the majority of Gram negative bacteria.
    Details
  • Aeromonas Agar This is a medium for the selective isolation of Aeromonas hydrophila from clinical, food and water samples. The medium is made selective by the inclusion of Brilliant Green and Irgasan, which are said to be less inhibitory to Aeromonas spp than Ampicillin used in some other media.
    Details
  • Mineral Modified Glutamate Medium with 1.5% Agar A modification of Mineral Modified Glutamate Medium where 15g/Litre of Agar has been added to create a plating medium suitable for the isolation of E.coli from food samples. Using this medium during the resuscitation stage allows for the recovery of E.coli from frozen, dried, heat-processed or low pH foods.
    Details
  • Bacillius cereus Selective Agar (PEMBA) This is a medium for the selective isolation and enumeration of Bacillus cereus in food samples. It is said to be particularly suitable for the detection of small numbers of Bacillus cereus particularly in the presence of other contaminating organisms. The medium is made selective by the inclusion of Polymixin and Sodium Pyruvate is also present which is said to improve Egg Yolk precipitation and enhance sporulation. As Bacillus cereus is Mannitol Negative the colonies are bluish in colour, due to the presence of the Bromothymol Blue Indicator, with a surrounding precipitate of the same colour due to Lecithinase production (from the Egg Yolk). NB:  It should be noted that some Proteus spp. and gram positive cocci may grow on this medium.
