NEOGEN Listeria Enrichment Broth, 5 kg
Listeria Enrichment Broth is used for selective enrichment of Listeria spp and is not intended for use in the diagnosis of disease or other conditions in humans.Listeria monocytogenes, first described in 1926 by Murray, Webb, and Swann, is an extensive problem in public health and food industries. This organism has the ability to cause human illness and death, particularly in immunocompromised individuals and pregnant women. Epidemiological evidence from outbreaks of listeriosis has indicated that the principle route of transmission is via consumption of foodstuffs contaminated with Listeria monocytogenes. Implicated vehicles of transmission include turkey frankfurters, coleslaw, pasteurized milk, Mexican style cheese, and pate. Listeria spp. are ubiquitous in nature, being present in a wide range of unprocessed foods as well as in soil, sewage, and river water.For more information visit https://www.neogen.com/solutions/Microbiology/listeria-enrichment-broth

NEOGEN Brilliant Green Agar (Modified), 5 kg
Brilliant Green Agar is used for the selection and differentiation of Salmonella (other than S. typhi) from foods or feedstuffs. Brilliant Green Agar is not intended for use in the diagnosis of disease or other conditions in humans. First introduced by Kristensen et al in 1925 as a selective medium for the isolation of Salmonella (except S. typhi). The medium was modified by the Netherlands Institute for Public Health, Utrecht. The modification was to increase the selectivity of the medium by increasing the dye concentration. This formulation is quoted by the International Standards Organization, standard European Community Methods, the American Public Health Association and the Association of Official Analytical Chemists. The medium is suitable for subcultures from selective enrichment media. However, because this medium is highly selective, small numbers of salmonellae may be missed.For more information visit https://www.neogen.com/solutions/Microbiology/brilliant-green-agar
NEOGEN Bacillus cereus MYP Agar, 500 g
Bacillus Cereus MYP Agar is used with supplements for the selective and differential enumeration of Bacillus cereus from foods. Conforms to ISO and FDA / BAM formulation in a laboratory setting. MYP Agar Base is not intended for use in the diagnosis of disease or other conditions in humans.Formulated to ISO 7932:2004 MYP was introduced by Mossel and his co-workers in 1967 for the enumeration of Bacillus cereus in foods and was shown to be the most effective for this purpose by Inal in 1972. B. cereus is differentiated from other members of the Bacillus group by two reactions: mannitol fermentation and lecithinase production. Mannitol fermentation on this medium produces a yellow color. B. cereus is mannitol negative and produces red colonies. The lecithinase production of B. cereus is indicated by a white precipitate around the colonies.For more information visit https://www.neogen.com/solutions/Microbiology/bacillus-cereus-myp-agar
NEOGEN EC Broth, 5 kg
EC Broth is used for the detection of coliform bacteria at 37°C and Escherichia coli at 44.5°C. EC Broth is not intended for use in the diagnosis of disease or other conditions in humans.EC Broth (Escherichia coli Broth) is a selective enrichment broth designed for the isolation of coliforms, including E. coli, from water and food samples. It was the recommended medium of the American Public Health Association (APHA) and the AOAC.EC Broth is made selective for coliforms by the inclusion of Bile Salts in the dehydrated medium. The selective nature of this medium ensures that the growth of non-coliform bacteria is minimized. The medium is buffered by the addition of potassium phosphates and osmotically balanced by sodium chloride. The medium is used at 37°C for coliform organisms and 44.5°C is recommended for the isolation E. coli.For more information visit https://www.neogen.com/solutions/Microbiology/ec-broth
NEOGEN Lactose Broth, 500 g
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
