A selective medium for the enrichment of Enterobacteriaceae and the detection of Escherichia coli in pharmaceutical products. The inclusion of Bromocresol Purple indicator makes the colour change caused by acid production from the fermentation of lactose easy to read with gas formation. The presence of Ox bile helps to suppress the growth of Gram positive and non-enteric bacterial species. This formulation complies with the Harmonized USP/EP/JP.
An osmotically controlled solution for the preparation of suspensions of food samples and for use as a diluent in dilution techniques for bacterial enumeration. The solution may also be used in the sampling of food production apparatus by the rinse and swab method.
This is a selective enrichment broth for the isolation of Salmonella spp. from pharmaceutical, food, dairy and environmental samples. Malachite Green and Magnesium Chloride are included in the formulation as selective agents due to their ability to inhibit most enteric organisms whilst allowing Salmonella spp. to multiply freely. Gram +ve bacteria and most other enteric bacteria, are typically susceptible to or inhibited by Malachite Green, the high osmotic pressure and/or the low pH of the medium. It should be noted that S.typhi and S.choleraesuis are sensitive to Malachite Green and may therefore be inhibited. This medium conforms to the requirements of the Harmonised USP/EP/JP.
This is a selective medium for the isolation of yeasts and fungi and is particularly suitable for use in sterility testing. The low pH (5.6) of the medium is inhibitory to most bacteria and many diagnostic features such as spores and pigmentation are well developed on this medium. The formulation of this medium conforms to the requirements of the Harmonized USP/EP/JP.
Sterile Isotonic Saline 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.
Tryptone Soya Broth is also commonly referred to as Soybean-Casein Digest Medium or Tryptic Soya Broth and is abbreviated as TSB. This is a general purpose and nutritious medium for the non-selective enrichment of non-fastidious and some fastidious organisms. Tryptone and Soy peptone are the nitrogen sources in the medium. Glucose is the carbon energy source that facilitates organism growth. Sodium chloride maintains osmotic balance; Di-potassium phosphate is a buffering agent to prevent auto-sterilisation due to acid production during the growth of some organisms. Tryptone Soya Broth formulation conforms to the Harmonized United States Pharmacopoeia (USP), European Pharmacopoeia (EU), and Japanese Pharmacopoeia (JP).
This is a general-purpose broth for cultivation of fastidious bacteria, yeasts and moulds. The medium incorporates Polysorbate 80 to act as an emulsifying agent and inactivate phenols. Lecithin is also incorporated to inactivate quaternary ammonium compounds. The medium can be incubated under aerobic or anaerobic conditions for sterility testing, and other areas of bacteriological investigation.
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.
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.
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).
This broth is used to aid the rinsing of the membrane filter apparatus when performing sterility testing. This formulation complies with the United States Pharmacopoeia.

Maximum Recovery Diluent (Peptone/ Saline Diluent) An osmotically controlled solution for the preparations of suspensions of food samples and for use as a diluent in dilution techniques for bacterial enumeration. The presence of a low level peptone lessens the physiological shock normally experienced by bacterial cells when they are introduced to a diluent such as Ringers Solution. The level of peptone is such that multiplication of the organisms is not possible in the time in which the sample will be present in the diluent.
For the detection of mould, yeast and acidophillic bacterial contamination of pharmaceutical products.
This medium is intended for use in sterility testing of substances in accordance with the United States Pharmacopoeia and European Pharmacopoeia. It is a general purpose medium for the cultivation of both fastidious anaerobic and aerobic micro-organisms. Sodium Thioglycollate and L-cystine are included to reduce the medium to ensure anaerobiosis and to inactivate mercury and other heavy metallic compounds. A small amount of agar is added to further reduce the update of oxygen. However, in the event of oxidation, the medium will turn pink due to the presence of the resazurin. Providing only 30% of the medium has turned pink, the Eh may be restored by heating the medium (once only) in a boiling water bath.
Lactose Broth is frequently used as a pre-enrichment medium when testing foods, water samples and dairy products for Salmonella spp. In dried or processed foods, Salmonella species may be sublethally injured and present in low numbers. Pre-enrichment in a nonselective medium such as Lactose Broth allows for repair of cell damage, dilutes toxic or inhibitory substances, and provides a nutritional advantage to Salmonella spp. over other bacteria.
This is a modified Cameron Sulphite Agar with a reduced concentration of sodium sulphite from 0.1% to 0.05% to allow the growth of the more sulphite sensitive strains of clostridia. A positive result is indicated by distinct black growth throughout the media, however, this blackening is only presumptive evidence of clostridial growth. Confirmation tests must be carried out to identify the organism growing on the medium.
This is a general-purpose complex medium for the cultivation and isolation of aerobic and anaerobic microorganisms. The base medium, Tryptone Soya Agar (Soybean-Casein Digest agar), conforms to the Harmonized United States Pharmacopoeia (USP), European Pharmacopoeia (EP), and Japanese Pharmacopoeia (JP). The medium can be incubated under aerobic or anaerobic conditions after use for sterility testing, air sampling and other areas of bacteriological investigation.
