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. -
Campylobacter Selective Agar Preston Supplement This is one of several selective media available for the isolation of Campylobacter spp in clinical, food and environmental laboratories. The medium is enriched with Lysed Horse Blood and made selective by the inclusion of Cefoperazone, to suppress other enteric organisms, and Amphotericin to suppress yeast & fungal growth. -
Campylobacter Selective (Skirrow) Agar This is one of several selective media available for the isolation of Campylobacter spp in clinical, food and environmental laboratories. Based on Columbia Agar enriched with Lysed Horse Blood. Polymyxin B, Trimethoprim & Vancomycin are added as the selective agents. Sodium Thiosulphate, Pyruvic Acid and Ferrous Sulphate are also included to enhance the aerotolerance of Campylobacter spp. NB: This medium should be incubated at 42°C to optimise selectivity. -
Edwards Medium (Modified) with 7% Sheep Blood This is a medium for the selective isolation of streptococci, particularly Streptococcus agalactiae, involved in bovine mastitis. The medium is enriched by the addition of 7% Sheep Blood and made selective by the inclusion of Crystal Violet and Thallous Sulphate. Aesculin is also present and assists in the differentiation of Streptococcus agalactiae, which give rise to blue colonies, from Aesculin positive Group D streptococci which produce black colonies. -
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), 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. One side of the bi-plate consists of standard FAA supplemented with 7% horse blood; the other side is FAA with horse blood and Neomycin (75mg/L) for the selective isolation of target organisms. -
Fastidious Anaerobe Agar (FAA) with 5% Sheep Blood 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) 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 further enriched by the addition of 5% Sheep Blood. -
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 and sodium bicarbonate), 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 further enriched by the addition of 5% horse blood. This product is suitable for use with the EUCAST disc diffusion method for selected rapidly growing anaerobic bacteria. -

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. -
Fastidious Anaerobe Agar with 7% Horse Blood, Vancomycin (6mg/L) & Nalidixic Acid (10mg/L) This is a selective medium for the isolation of gram-negative anaerobes from clinical specimens. The base medium, Fastidious Anaerobe Agar, is complex and includes detoxification agents (Starch & Sodium Bicarbonate), growth enhancing agents (Cysteine, Arginine, Vitamin K, Sodium Succinate, Glucose and pyrophosphate) as well as Haemin to encourage pigment production where appropriate. Sodium Pyruvate is also included to help neutralise Hydrogen Peroxide. The medium is made selective, by the inclusion of Naladixic Acid and Vancomycin and further enriched by the addition of 7% Horse Blood. -
This is a selective medium for the isolation of clinically significant anaerobes including fastidious organisms. The formulation is complex and includes detoxification agents (starch and sodium hydrogen carbonate), growth enhancing agents (cysteine, arginine, menadione, sodium succinate, glucose and pyrophosphate) and haemin to encourage pigment production in Porphyromonas melaninogenicus. Sodium pyruvate is included to help neutralise hydrogen peroxide. The medium is made selective by the inclusion of nalidixic acid and further enriched by the addition of 7% defibrinated horse blood. Tween 80 is added to encourage the growth of anaerobic streptococci. -

A selective culture medium for the isolation and differentiation of Corynebacterium diphtheriae types, Hoyle’s medium allows for rapid growth of the organisms and normally 18 hours incubation should be sufficient for a diagnosis. As the medium is highly selective, inoculation should be by rubbing the swab (or other material) over the entire surface of the agar, there is no need to spread the inoculum with a loop indeed doing so can cause the organism to be missed especially when they are present only in small numbers.
