Description: For the antibiotic sulphonamide residue test according to Kundrat. The <i>Geobacillus stearothermophilus</i> spore suspension is used in conjunction with the test agar for performing the antibiotic sulphonamide residue test according to Kundrat, Cat. No. 1.10662. The test detects antimicrobial residues such as antibiotics, sulphonamides and other chemotherapeutics in meat and other foodstuffs of animal origin. It is a routine qualitative procedure. The test is based on agar diffusion, using spores of <i>Geobacillus stearothermophilus</i> as test organisms. Antibiotic and sulphonamide residues inhibit the growth of the test organism. Cleaning agents, disinfectants and preservatives do not influence the test.

Description: Microbiological laboratories need a simple procedure to maintain important microorganisms rather than repetitive sub-culturing, which results in contaminated cultures, loss of viability and, even more importantly, loss of original characteristics by introducing biochemical and genetic changes. Cryoinstant consists of 25 porous beads in a vial filled with a broth containing glycerol. Microorganisms will bind to the porous surface of the beads. The excess broth is aspirated, and the vials stored at temperatures down to –70 °C in a freezer.

Description: Most individuals infected with <i>Salmonella </i>develop diarrhea, fever, and abdominal cramps 12 to 72 H after infection. The illness usually lasts 4 to 7 days, and the majority of patients recover without treatment. However, in some cases, the diarrhea may be so severe that hospitalisation is required. <i>Salmonella</i> is a genus of rod-shaped, Gram-negative, non spore-forming, predominantly motile bacteria, belonging to the Enterobacteriaceae family.<i> Salmonella spp.</i> are one of the most common causes of food poisoning worldwide and have been isolated from most types of raw food (e.g. meats, eggs and plant products). Their high resistance to drying combined with a very high heat resistance once dried makes Salmonella a potential problem in most foods, particularly in dry and semi-dry products. Food legislation in many countries includes limits on Salmonella – typically absence in 25 g of food. Traditional microbiological methods for detection of <i>Salmonella</i> in food and animal feed require a total of up to five days to obtain a simple yes/no result. Innovative, rapid tests make screening for pathogenic organisms easier. The one-step format reduces the possibility of errors during handling.

Description: Listeria monocytogenes is one of the most widely distributed foodborne pathogens in the world and is responsible for severe infections in immunocompromised persons, pregnant women and neonates. As a result, the mortality rate in infected individuals is high despite the relatively low number of cases around the world. Listeria infections (listeriosis) can result in anything from mild gastroenteritis to severe cases of sepsis, meningitis, encephalitis or abortion. Due to the ubiquitous distribution of<i> Listeria</i> and their capability to grow at refrigeration temperatures ( 2 to 8 °C), food products constitute one of the main sources of infection.<i> Listeria</i> is a genus of Gram-positive, non-sporeforming, rod-shaped bacteria. Of the six known species of the genus Listeria,<i> Listeria monocytogenes</i> deserves particular mention as a human and animal pathogen;<i> L. ivanovii </i>is only pathogenic in animals, while<i> L. innocua</i>,<i> L. seeligeri</i>,<i> L. grayi</i>, and<i> L. welshimer</i>i are considered harmless environmental bacteria. Consequently, food legislation in many countries specifies strict limits for<i> Listeria spp.</i> or<i> Listeria monocytogenes</i>. In the conduct of risk-related quality controls in food, tests should be run for<i> L. monocytogenes</i>, and for the Listeria Genus in general. The presence of Listeria – in particular of<i> L. innocua</i> – is an indicator for critical hygienic conditions in the production process. Innovative, rapid tests make screening for pathogenic organisms easier. The one-step format reduces the possibility of errors during handling.

Description: Campylobacteriosis is an infection caused by Campylobacter, most commonly C. jejuni. It produces an inflammatory, sometimes bloody, diarrhea or dysentery, including cramps, fever and abdominal pain. The debilitating neurological disorder, Guillain-Barre Syndrome (GBS), as well as reactive arthritis have also been associated with recent infections with certain <i>C. jejuni strains. C. lari </i>and the emerging pathogen,<i> C. upsaliensis</i>, have also been reported in a small percentage of cases of human Campylobacter infection.<i> Campylobacter</i> <i>spp.</i> are highly infectious - as few as 500 bacteria can cause illness. There is an increasing demand for Campylobacter testing in food to meet regulations regarding Campylobacter levels in poultry. The majority of Campylobacter spp. are relatively metabolically inactive, making identification based on biochemical characteristics difficult. Currently, the most commonly used techniques to test food products for Campylobacter are traditional methods based on culture media. Innovative, rapid tests make screening for pathogenic organisms easier. The one-step format reduces the possibility of errors during handling.

Description: EHEC is capable of inducing life threatening illnesses, particularly in people with immune deficiency, young children and the elderly. Although the most common cause of EHEC is <i>E. coli</i> O157, other serotypes, such as O26, O45, O103, O111, O121 and O145, are also relatively frequent causes of infection. Typical symptoms are severe abdominal pain and diarrhoea, which is initially watery but often becomes bloody. <i>E. coli</i> are gram-negative, non sporulating, facultative anaerobic bacilli. Amongst the pathogenic <i>E. coli</i>, Verotoxin-forming strains (STEC or VTEC) have gained importance in recent years. The group of enterohaemorrhagic <i>E. coli</i> (EHEC) with its highly pathogenic serovar O157:H7 strain is particularly interesting in this respect. The main sources of infection are contaminated, raw or insufficiently heated foods of animal origin, such as meat and dairy products. The reservoir for EHEC is the gut of ruminants. Microorganisms can enter food during the processing of meat and dairy products if hygienic conditions are inadequate. The drastic increase in the incidence of food contamination caused by <i>E. coli</i> O157 demands reliable and rapid methods of detection. Innovative, rapid tests make screening for pathogenic organisms easier. Complete test sets for the detection of pathogens and toxins. The one-step format reduces the possibility of errors during handling. In addition to tests for the most common cause of infection, <i>E. coli</i> O157, there exits a 24-H screening protocol for VTEC, including <i>E. coli</i> O104:H4, based on Rapidcult™ <i>E. coli</i> enrichment combined with detection using Duopath® Verotoxins.
