Microbiology Test Systems

The microbiological test systems enable you to obtain molecular-biological proof of pathogens and their resistances. Choose from a vast array of products specialized for the isolation and identification of different microbiological strains, for use in the field or in laboratory settings. All products are highly accurate and deliver reliable and reproducible results, with rapid detection systems available for fast and cost-effective diagnostics.

Microbiology detection tests, Bactident®

Supplier: Merck

The presence or absence of enzyme activity is a taxonomic property of microorganisms and can be used for their differentiation or identification.

Spore suspension, Geobacillus stearothermophilus

Supplier: Merck

For the antibiotic sulphonamide residue test according to Kundrat. The Geobacillus stearothermophilus 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 Geobacillus stearothermophilus as test organisms. Antibiotic and sulphonamide residues inhibit the growth of the test organism. Cleaning agents, disinfectants and preservatives do not influence the test.

VWR® Preservation System, Cryoinstant

Supplier: VWR Chemicals

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.

Lateral Flow test for Campylobacter, Singlepath® Campylobacter

Supplier: Merck

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.

Lateral Flow test for Listeria, Singlepath® Listeria

Supplier: Merck

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.

Whatman antibiotic assay discs

Supplier: Whatman products (Cytiva)

For determining the type of causal agent of infectious diseases and for checking their sensitivity to antibiotics and chemotherapeutic agents in vitro by means of the inhibition zone determination method. The antibiogram allows rational and selective chemotherapy. The test disks are coated with chemotherapeutic agents, placed on the inoculated nutrient agar and incubated. The size of the inhibition zone is a measure for the effectiveness of the substances.
