  • This is a selective medium for the isolation of Actinomyces spp. from clinical specimens. It is based on Fastidious Anaerobe Agar that has been enriched with 7% defibrinated horse blood and made selective by the addition of nalidixic acid to inhibit most aerobes (particularly Gram-negative bacilli) and metronidazole to suppress other anaerobes.
  • This is a 25ml fill selective medium for the isolation of Actinomyces spp from clinical specimens. Based on Fastidious Anaerobe Agar enriched with 7% Horse Blood, the medium has been made selective by the inclusion of Nalidixic Acid to inhibit most aerobes, particularly gram-negative bacilli, and Metronidazole to suppress other anaerobes.
  • Bacillus Cereus (Mannitol Egg Yolk Polymixin - MYP) Agar Intended for the selective enumeration of Bacillus cereus in food samples the medium uses two reactions (Mannitol fermentation and Lecithinase production) to differentiate Bacillus cereus from other members of the species. As Bacillus cereus is Mannitol Negative the colonies are pink in colour due to the presence of Phenol Red Indicator. Lecithinase production (from the Egg Yolk) is indicated by a white precipitate around the colonies. Polymixin is added as the selective agent to inhibit coliforms. NB: It should be noted that some Proteus spp and gram positive cocci may grow on this medium.
  • Bile Aesculin Agar 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.
  • A general-purpose medium enriched with 7% Horse Blood, suitable for the isolation of most organisms including many fastidious anaerobes of clinical significance.
  • Brazier's CCEY Agar with 1% Lysed Horse Blood - Blood, Cycloserine, Cefoxitin, 4% Egg Yolk Emulsion Based on Fastidious Anaerobe Agar, Cholic Acid and p-Hydroxyphenylacetic Acid are added to enhance the isolation and differentiation of Clostridium difficile from clinical specimens. Cholic Acid promotes spore germination and p- Hydroxyphenylacetic Acid enhances production of p-cresol, a distinctive metabolite of Clostridium difficile. The medium is made selective by the inclusion of Cefoxitin and D-Cycloserine and Egg Yolk emulsion is added to differentiate Clostridium difficile from the Lecithinase producing clostridia. Lysed Blood is also added which optimises the colony fluorescence when cultures are examined under UV light.
  • Brucella Agar is a non-selective medium that is enriched with peptones, 5% sheep blood, haemin and vitamin K to support the growth of fastidious, slow growing, obligately anaerobic micro-organisms.
  • Brucella agar is an enriched non-selective medium that supports the growth of fastidious and slow growing, obligately anaerobic micro-organisms due to its content of peptones, dextrose and yeast extract. The medium is supplemented with sheep blood, haemin and vitamin K which provide essential nutrients for certain anaerobes.
