m-Enterococcus Agar - 500 g

£127.69 vat excl.

£153.23 vat Inc.
Availability: Out of stock
m-Enterococcus Agar is used for the selective isolation and enumeration of enterococci by membrane filtration in a laboratory setting. m-Enterococcus Agar is not intended for use in the diagnosis of disease or other conditions in humans. m-Enterococcus Agar was first described by Slanetz et al. for the enumeration of enterococci by the membrane filtration technique. In 1957, Slanetz and Bartley modified this medium by adding triphenyl tetrazolium chloride (TTC). Increased recovery and larger colonies were obtained by incubating the inoculated membranes on the agar surface instead of on pads saturated with liquid medium. The membrane filtration method is simple to perform, does not require confirmation, and permits a direct count of enterococci in 48 hours. m-Enterococcus Agar is also referred to as m-Azide Agar. The presence of enterococci is a valuable bacterial indicator for determining the extend of fecal contamination of recreational surface waters. m-Enterococcus Agar is recommended for the detection of fecal streptococci using the membrane filtration technique for water testing. The food industry also has applications for testing enterococci using m-Enterococcus Agar.

Availability: Out of stock
Tryptic Soy Broth, Modified with Novobiocin is used for the selective enrichment of enterohemorrhagic E. coli in foods in a laboratory setting. Tryptic Soy Broth, Modified with Novobiocin is not intended for use in the diagnosis of disease or other conditions in humans. The first major outbreak of E. coli O157:H7 was in 1982 and traced to contaminated hamburgers. Other known sources of infection include sprouts, lettuce, salami, unpasteurized milk, juice and/or swimming in or drinking contaminated water. Tryptic Soy Broth, Modified with Novobiocin is used to enrich food samples suspected of having low levels of EHEC during pathogen testing.

Eosin Methylene Blue (EMB) Agar Levine

£1,041.27 vat excl.

£1,249.52 vat Inc.
Availability: Out of stock
Eosin Methylene Blue Agar Levine is used for the isolation and differentiation of Gram-negative enteric bacilli and is not intended for use in the diagnosis of disease or other conditions in humans. This medium was introduced in 1916 by Holt-Harris and Teague to differentiate Escherichia spp. and Aerobacter spp. It was modified by Levine in 1918 who removed sucrose from the formula and increased the lactose content. The distinctive metallic sheen produced by E. coli on this medium is due to acid production resulting in an amide bonding between the eosin and methylene blue, other coliforms do not produce enough acid to cause this reaction. Eosin inhibits most Gram-positive organisms. The prepared medium is sensitive to light.

Availability: Out of stock
Xylose Lysine Deoxycholate (XLD) Agar (ISO) is a selective agar for the detection of Salmonella spp. in food, animal feed and in environmental samples from the food production area as described in ISO 6579-1:2017. Xylose Lysine Deoxycholate (XLD) Agar (ISO) is not intended for use in the diagnosis of disease or other conditions in humans. A selective, diagnostic agar for the detection of Salmonella spp. in food, animal feed and in environmental samples from the food production area as described in ISO 6579-1:2017. Originally formulated by Taylor to differentiate enteric pathogens, the agar is widely used as the preferred differential medium for Salmonella spp. The medium is void of peptones but instead uses yeast extract as a carbon, nitrogen and vitamin source and xylose, lactose and sucrose are fermentable carbohydrates. Salmonella are able to ferment xylose to produce acid but not lactose or sucrose. When the xylose is exhausted Salmonella will decarboxylate lysine shifting the pH back to neutral. At near neutral pH, Salmonella can reduce sodium thiosulfate producing hydrogen sulfide which creates a complex with ferric ammonium citrate to produce black or black centred colonies. Other organisms are able decarboxylate lysine but acid production from the fermentation of lactose and sucrose keeps the pH too acidic for H2S production. Selectivity is achieved through the incorporation of sodium deoxycholate and phenol red acts as a pH indicator. According to ISO 6579-1:2017, subculture is performed separately from both Rappaport-Vassiliadis medium with Soya (RVS) and Muller-Kauffmann tetrathionate-novobiocin (MKTTn) broth. This medium conforms to the performance and formulation requirements of ISO 6579-1:2017.

DRYSWAB™ - Plastic Shaft Rayon Tip

DRYSWAB™ - Plastic Shaft Rayon Tip

Tip - Rayon: Rayon, also known as Viscose, is a processed form of cellulose and has been found to be particularly suitable for the recovery of microorganisms. The texture is similar to that of cotton, but it has none of the fatty acids or other substances that can be inhibitory to fastidious bacteria. It has also been shown to be compatible with many molecular based diagnostic tests. Rayon buds are used on most of our transport swabs.

Traditionally, the bud on the swab has consisted of a spun fibre such as cotton, rayon, polyester or calcium alginate wound round the end of the shaft which would be wood, plastic or wire. In recent years, novel bud materials have been introduced, such as soft cellular polyurethane foam, or flocked fibres which can give improved uptake and release of specimens. Medical Wire have extensive ranges of swabs utilising either spun fibres, cellular foam, or multifilament flock fibres, with something suitable for many applications.

Brilliant Green Agar with Sulfapyridine - 500 g

£99.00 vat excl.

£118.80 vat Inc.
Availability: Out of stock
Brilliant Green Agar w/ Sulfapyridine is used for the selective enrichment of Salmonella spp. in a laboratory setting. Brilliant Green Agar w/ Sulfapyridine is not intended for use in the diagnosis of disease or other conditions in humans. Brilliant Green Agar was first described by Kristensen et al and later modified by Kauffmann. The outstanding selectivity of this medium permits the use of moderately heavy inocula evenly distributed over the surface. The addition of sulfonamides into Brilliant Green Agar further inhibits Escherichia coli and Proteus spp. Osborne and Stokes used 0.1% Sodium Sulfapyridine to enhance the recovery of Salmonella from whole egg and egg yolk.
