Convenient dehydrated culture media of the highest quality are provided for the growth of a wide range of heterotrophic organisms. Our Media Explorer will help you select the right media for microbial analysis, for the optimal growth of a certain organisms, and for the isolation of microorganisms from complex samples. Choose from more recently developed media to classical media for the identification or cultivation of bacteria and fungi.

Food and water contaminated by microorganisms (bacteria and yeasts), viruses and protozoa can cause severe disease in humans, especially in people weakened by illness or during convalescence, malnutrition, etc. There are two categories of foodborne diseases. First, food poisoning is caused by the presence of microbial toxins in food products, e.g. by Staphylococcus aureus, Clostridium perfringens (both produce enterotoxins which elicit enteric disease such as. diarrhea) and Clostridium botulinum (botulism the most severe type of food poisoning).

Second, food infection is caused by the growth of microorganisms in the body after eating contaminated food, e.g. by Salmonella spp. (salmonellosis) and Campylobacter jejuni (high fever, abdominal cramps). Many human pathogens are transmitted by fecally contaminated water, the most important are Salmonella typhi (typhoid fever) and Vibrio cholerae (cholera). Microbiological test procedures for the examination of food and water have been standardized and regulated, but nearly every country has its own regulations, the "Schweizerisches Lebensmittelhandbuch" being a case in point. Most culture media, their additives, dyes and indicators which we offer conform to Swiss regulations or other norms like IOS.
