För antibiotisk sulfonamid resttest enligt KUNDRAT. Geobacillus stearothermophilus sporsuspension används i kombination med testagar för att utföra antibiotisk sulfonamid resttest enligt KUNDRAT, art.nr 1,10662. Testet detekterar spår av antimikrobiella substanser som antibiotika och sulfonamider i kött och andra livsmedel av animaliskt ursprung. Testet baseras på agar-diffusion med hjälp av sporer av Geobacillus stearothermophilus som testorganismer. Antibiotika och sulfonamid-rester hämmar tillväxten av testorganismen. Rengöringsmedel, desinfektionsmedel och konserveringsmedel påverkar inte testet.

Mikrobiologiska laboratorier behöver en enkel procedur för bevarande av viktiga mikroorganismer, i stället för ständig vidareodling som leder till kontaminerade kulturer, minskad livsduglighet och introduktion av biokemiska och genetiska modifieringar. Cryoinstant består av 25 porösa kulor i en flaska fylld med buljong som innehåller glycerol. Mikroorganismer binds till kulornas porösa yta. Överskottet av buljong sugs av och flaskorna förvaras i frys vid ned till –70 °C.

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 C. jejuni strains. C. lari and the emerging pathogen, C. upsaliensis, have also been reported in a small percentage of cases of human Campylobacter infection. Campylobacter spp. 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.

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 Listeria and their capability to grow at refrigeration temperatures ( 2 to 8 °C), food products constitute one of the main sources of infection. Listeria is a genus of Gram-positive, non-sporeforming, rod-shaped bacteria. Of the six known species of the genus Listeria, Listeria monocytogenes deserves particular mention as a human and animal pathogen; L. ivanovii is only pathogenic in animals, while L. innocua, L. seeligeri, L. grayi, and L. welshimeri are considered harmless environmental bacteria. Consequently, food legislation in many countries specifies strict limits for Listeria spp. or Listeria monocytogenes. In the conduct of risk-related quality controls in food, tests should be run for L. monocytogenes, and for the Listeria Genus in general. The presence of Listeria – in particular of L. innocua – 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.

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 E. coli 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. E. coli are gram-negative, non sporulating, facultative anaerobic bacilli. Amongst the pathogenic E. coli, Verotoxin-forming strains (STEC or VTEC) have gained importance in recent years. The group of enterohaemorrhagic E. coli (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 E. coli 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, E. coli O157, there exits a 24-H screening protocol for VTEC, including E. coli O104:H4, based on Rapidcult™ E. coli enrichment combined with detection using Duopath® Verotoxins.

Katalastestet gör det möjligt att särskilja eller identifiera mikroorganismer som kontrollerar sin förmåga att producera katalas, ett enzym som skyddar mikroorganismer från toxiska syremetaboliter. Vanligtvis är det bara aeroba mikroorganismer som framställer katalas.
