NEOGEN Lactose Broth, 10 kg
Lactose Broth is used for the cultivation of Salmonella and coliform bacteria from food, dairy, and water products in a laboratory setting. Lactose Broth is not intended for use in the diagnosis of disease or other conditions in humans. Lactose Broth is frequently used as a pre-enrichment medium when testing foods and dairy products for Salmonella spp. In dried or processed foods, Salmonella species may be sub-lethally injured and in low numbers. The presence of other bacteria as well as components of the food sample may hinder growth and recovery of Salmonella. Pre-enrichment in a non-selective medium such as Lactose Broth allows for repair of cell damage, dilutes toxic or inhibitory substances, and provides a nutritional advantage to Salmonella over other bacteria.For more information visit https://www.neogen.com/solutions/Microbiology/lactose-broth

Formulated to ISO 6579-1:2017, ISO 22694:2017, ISO 21528-1:2017 and ISO 12950:2010. This pre-enrichment medium is designed to help sublethally damaged salmonellae recover before introducing them into a selective medium. This nutrient medium is free from inhibitors and is well buffered to maintain pH 7.0 for the incubation period. Sublethal injury to salmonellae occurs in many food processes and this pre-enrichment step greatly increases recovery of these organisms.

NEOGEN Violet Red Bile Agar (VRBA), 500 g
Violet Red Bile Agar is used for the enumeration of coliforms in food and dairy products in a laboratory setting. Violet Red Bile Agar is not intended for use in the diagnosis of disease or other conditions in humans and conforms to American Public Health Association (APHA). The coliform group of bacteria includes aerobic and facultative anaerobic, gram-negative, non-spore forming bacilli. Coliforms ferment lactose and form acid and gas at 35°C within 48 hours. Members of Enterobacteriaceae comprise the majority of the group, but other lactose fermenting organisms may also be included. Procedures to detect, enumerate, and presumptively identify coliforms are used in testing foods and dairy products. One method for performing the presumptive test for coliforms uses Violet Red Bile Agar, (VRBA).For more information visit https://www.neogen.com/solutions/Microbiology/violet-red-bile-agar
NEOGEN Columbia Blood Agar Base, 500 g
Columbia Blood Agar Base is used with blood for the isolation and cultivation of a wide variety of fastidious microorganisms. Columbia Blood Agar Base is not intended for use in the diagnosis of disease or other conditions in humans. A modification of the original Columbia Agar base formulation, Columbia Blood Agar Base provides a medium that is suitable for use with both defibrinated horse or sheep blood. The peptone mixture provides a source of nitrogen, essential vitamins and amino acids. The starch provides a carbon source and sodium chloride maintains osmotic balance. Originally described as a general purpose nutritious agar base by Ellner et al. Columbia Agar is more frequently used when enriched by the addition of sterile blood. The medium is suitable for supporting the growth and determining hemolytic reactions of a variety of microorganisms.

NEOGEN Buffered Peptone Water (BPW), 500 g
Buffered Peptone Water (BPW) is used for the non-selective pre-enrichment of Salmonella spp. from food and is not intended for use in the diagnosis of disease or other conditions in humans. Edel and Kamelmacher found that food preservation techniques involving heat, desiccation, preservatives, high osmotic pressure, or pH changes cause sublethal injury to Salmonella spp. Preenrichment in a non-selective medium allows for repair of cell damage and facilitates the recovery of Salmonella. Lactose Broth is frequently used for this purpose, but it may be detrimental to recovering Salmonellae. Buffered Peptone Water maintains a high pH over the pre-enrichment period and allows in repair of injured cells that may be sensitive to low pH. This is particularly important for vegetable specimens which have a low buffering capacity. Buffered Peptone Water is used in standard methods.
