Biobank for Biofilms, Implants and associated Tissues


BIT was established in 2009 and is located at Hannover Medical School (MHH). It represents an important link between the clinical activities of the various medical disciplines and basic research in the field of biofilm-associated  implant infections.

Collected swabs from infected natural and artificial surfaces, all implants with biofilm buildup and associated tissues and body fluids such as blood and saliva.

The aim of the research is a better understanding of complex micro- and molecular biological processes that lead to the emergence of implant infections.


(Collected samples per year)

  • 1000 DNA samples from 300 donors biofilms
  • 200 cDNA / RNA samples from biofilms from 50 donors
  • 100 serum samples from 100 donors
  • 100 plasma samples from 100 donors
  • 400 saliva samples of 200 donors
  • 100 tissue samples from 100 donors
  • 100 implants


The samples are stored at -80 ° C.



  • broad consent.
