Detection methods

We use the following classical microbiological methods for foodstuffs, animal feed, utensils and pharamaceutical products:

Detection methods (quantitative)

  • Spatula plate method
  • Spiral plate method
  • Drip plate method
  • Pour plate method
  • Diaphragm filtration
  • Airborne germ determination

Detection methods (qualitative)

  • Presence/Absence
  • MPN method

Detection methods (semi-quantitative)

  • Contact slide method
  • Contact plate method

Confirmation reactions

  • VITEK 2TM compact
  • Real-time PCR (multiplex/singleplex)
  • MALDI-TOF (cooperation partner)
  • API®/Microbact™
  • Classic biochemical confirmation reactions
  • Microscopy
  • Fluorescence microscopy

As well as the classic microbiological procedures, for specific parameters the Institute Kirchhoff also offers molecular biological techniques. A frequently used method is real-time PCR. This is characterised by speed, specifity, sensitivity and automated technology.

Real-time PCR (multiplex/singleplex)

  • Salmonella spp.
  • Escherichia coli
  • Campylobacter spp./C. coli, C. jenuni, C.lari
  • Listeria monocytogenes
  • Cronobacter spp.
  • Legionella spp./L pneumophila
  • Methicillin-resistant staphylococcus aureus (MRSA)
  • VTEX stx1/2

Furthermore, the Institut Kirchhoff also uses fluorescence microscopy and fluourescence in situ hybridisation (FISH). VITEK 2TM compact is used for indentifying bacteria and detecting resistance.

For more information on this topic, our regularly trained staff would be pleased to assist.
