Multiresistant Bacteria

​Diagnosis in hospital hygiene laboratory

Episode smears of patients with multi-resistant germs

The laboratory for hospital hygiene investigated episode smears of isolated patients following multiresistant germs:

  • Methicillin-resistant Staphylococcus aureus (MRSA)
  • Vancomycin resistant Enterococci
  • Multiresistant Gram negative rods (multi drug resistant, MDR)
  • Extended spectrum beta lactamase (ESBL)-producers
  • Carbapenemase producing enterobacteriaceae, (CPE)

Microbiological analyzes of hospital hygienic relevance

  • Microbial air measurements (Aspergillus, Mycobacteria)
  • Water Testing (Legionella)
  • Microbiological controls of medical devices

Investigations in cases of suspected transmission of multi-resistant germs

  • Typing of bacteria
  • Environment studies

Relevance in everyday life and for hospital hygiene

Prevention of nosocomial infections

  • Microbiological testing of medical devices helps preventing the spread of multidrug-resistant germs.
  • In case of suspected transmission possible transmission paths areidentified and prevented.

Economic aspects

The regular monitoring of multi-resistant germs of populated patients guarantees the earliest possible entisolation and thus the greatest possible cost savings.
