Rappaport Vassiliadis R10 Broth

£944.44 vat excl.

£1,133.33 vat Inc.
Availability: Out of stock
Rappaport Vassiliadis R10 Broth is used for the selective enrichment of Salmonella spp. from foods in a laboratory setting. Rappaport Vassiliadis R10 Broth is not intended for use in the diagnosis of disease or other conditions in humans. Rappaport et al formulated an enrichment medium for Salmonella spp. that was modified by Vassiliadis et al. The Rappaport formulation, designated R 25/37°C, recommended incubation at 37°C. The Vassiliadis modification, designated R 10/43°C, had a reduced level of Malachite Green and recommended incubation at 43°C. Peterz later showed that incubation at 41.5 ± 0.5°C for 24 hours improved recovery of Salmonella spp. Rappaport-Vassiliadis R10 Broth is a selective enrichment medium that is used following pre-enrichment of the specimen. It has gained approval for use in analyzing milk and milk products, raw flesh foods, highly contaminated foods, and animal feeds. This medium selectively enriches for Salmonella spp. because bacteria, including other intestinal bacteria, are typically susceptible to or inhibited by Malachite Green, high osmotic pressure and/or low pH. S. typhi and S. choleraesuis are sensitive to Malachite Green and may be inhibited.

Bile Aesculin Agar

£2,198.40 vat Inc.
Availability: Out of stock
Bile Esculin Agar is used for the selective isolation and differentiation of group D streptococci from foods and is not intended for use in the diagnosis of disease or other conditions in humans. Bile Esculin Agar is based on the formulation described by Swan and further evaluated by Facklam and Moody. Rochaix first noted the value of esculin hydrolysis in the identification of enterococcci. Meyer and Schonfeld added bile to the esculin medium and demonstrated 61 of 62 enterococci strains were able to grow and hydrolyze esculin, while other streptococci could not. Molecular taxonomic studies of the genus Streptococcus have placed enterococci, previously described as group D streptococci, in the genus Enterococcus. The ability to hydrolyze esculin in the presence of bile is a characteristic of enterococci and group D streptococci. Swan compared the use of an esculin medium containing 40% bile salts with the Lancefield serological method of grouping, and reported that a positive reaction on the bile esculin medium correlated with a serological group D precipitin reaction. Facklam and Moody found that the bile esculin test provided a reliable means of identifying group D streptococci and differentiating them from non-group D streptococci.

Soy Peptone

£854.50 vat excl.

£1,025.40 vat Inc.
Availability: Out of stock
Soy Peptone is for use in preparing microbiological culture media in a laboratory setting, and is not intended for use in the diagnosis of disease or other conditions in humans. Soy peptone is a rich source of nutrients with a high carbohydrate content. Most organisms will grow rapidly in this peptone but some bacteria will produce high levels of acid leading to auto-sterilization unless an adequate buffering system is incorporated.

Availability: Out of stock
Sabouraud Dextrose Agar with Chloramphenicol is used for the selective isolation of fungi in a laboratory setting. Sabouraud Dextrose Agar with Chloramphenicol is not intended for use in the diagnosis of disease or other conditions in humans. Sabouraud Dextrose Agar (SDA) is a modification of Dextrose Agar described by Sabouraud. Sabouraud Dextrose Agar is used for cultivating pathogenic and commensal fungi and yeasts. The high dextrose concentration and acidic pH of the formula permits selectivity of fungi. This medium is beneficial in sporulation studies and pigment production. Sabouraud Dextrose Agar is used for determining the microbial content of cosmetics and in the mycological evaluation of food. Sabouraud Dextrose Agar with Chloramphenicol is a modification of Sabouraud Dextrose Agar, with the addition of Chloramphenicol to increase selectivity against commensal microorganisms.
