NEOGEN Buffered Listeria Enrichment Broth Base, 5 kg
Buffered Listeria Enrichment Broth Base is used with supplements for selective enrichment of Listeria spp. in foods and is not intended for use in the diagnosis of human disease.Listeria monocytogenes, described first 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.For more information visit https://www.neogen.com/solutions/Microbiology/buffered-listeria-enrichment-broth-base
NEOGEN Bile Esculin Azide Agar, 10 kg
Bile Esculin Azide Agar is used for the selective isolation and differentiation of group D streptococci in a laboratory setting. Bile Esculin Azide Agar is not intended for use in the diagnosis of disease or other conditions in humans.Bile Esculin Azide Agar is a modification of the medium reported by Isenberg and Isenberg, Goldberg, and Sampson. This formula modifies Bile Esculin Agar by adding sodium azide and reducing the concentration of bile. The revised medium is more selective, but still provides rapid growth and efficient recovery of group D streptococci.Molecular taxonomic studies of the genus Streptococcus have placed enterococci, previously described 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.For more information visit https://www.neogen.com/solutions/Microbiology/bile-esculin-azide-agar

NEOGEN Malt Extract, 10 kg
Malt Extract is a dehydrated extract of malt for use in preparing microbiological culture media in a laboratory setting. Malt Extract is not intended for use in the diagnosis of disease or other conditions in humans.Malt Extract is a clarified, water-soluble extract of malted barley. Malt Extract is a useful ingredient of culture media designed for the propagation of yeasts and molds. This ingredient is suitable for yeasts and molds because it contains a high concentration of carbohydrates, particularly maltose. The approximate percentage of reducing sugars in Malt Extract is 60 – 63%.The high carbohydrate content makes malt extract very sensitive to overheating which results in darkening of the medium it is used in. Malt Extract is generally employed in culture media at concentrations between 10 to 100 grams per liter.For more information visit https://www.neogen.com/solutions/Microbiology/malt-extract

NEOGEN Soy Peptone, 500 g
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. Prepared using the enzyme papain to digest soyabean meal, this 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.For more information visit https://www.neogen.com/solutions/Microbiology/soy-peptone

NEOGEN Yersinia Slective Agar (Schiemann's CIN Agar), 500 g
Yersinia Selective Agar is used with cefsulodin and novobiocin for the isolation of Yersinia enterocolitica in a laboratory setting. Yersinia Selective Agar is not intended for use in the diagnosis of disease or other conditions in humans. This medium is based on the work of Schiemann. It is used for the isolation and enumeration of Yersinia spp. from clinical samples and from food. The selective components are sodium desoxycholate, crystal violet, cefsulodin, irgasan and novobiocin. Yersiniae ferment mannitol with an intense, localized, acid production in the center of the colony which produces a red ‘bull’s eye’ appearance. The ratio of transparent border to red centre varies with serotype and environmental strains may appear rough with an irregular edge. Most other enteric bacteria, if they grow, produce a larger colony with a diffuse pinkish center and opaque outer zone.For more information visit https://www.neogen.com/solutions/Microbiology/yersinia-selective-agar
NEOGEN LESS Plus Medium Irradiated, 10 kg
Listeria monocytogenes, described first 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 indicates the principle route of transmission is via the consumption of foods contaminated with Listeria monocytogenes. Implicated vehicles of transmission include meat, eggs, chicken, vegetables, and dairy products. Listeria spp. are ubiquitous in nature, present in a wide range of unprocessed foods and in soil, sewage, and river water. Certain strains of Listeria spp. are able to survive the manufacturing and ripening processes in dairy products.For more information visit https://www.neogen.com/solutions/Microbiology/less-plus-medium
