Rapid microbiological diagnostics for implant infections

Special ultrasonic bath for the gentle removal of biofilms

Successful treatment of implant infections depends on a precise microbiological diagnosis. Because microorganisms on foreign parts of the body bio-
films, they are often difficult to detect in the surrounding tissue. With the help of BactoSonic, biofilms can be gently removed from the surface of an infected implant.

Working principle of the BactoSonic

The implant is placed in the liquid of the corresponding box and sonicated in the BactoSonic ultrasonic bath specially developed for this procedure. Compared to other ultrasonic baths, this device works with low-frequency ultrasound at low intensity and high homogeneity. The aim is to remove the biofilm without destroying the bacteria, which must be preserved for subsequent analysis. The liquid obtained is microbiologically processed and the amount of bacteria is quantified. Up to 10,000 times more bacteria can be detected than with usual methods, such as from biopsies of periprosthetic tissue. Mixed infections and different bacterial morphotypes can be better detected. Sensitivity is improved, especially in patients with prior antibiotic therapy.

Implants and infection

With the increasing use of medical implants, we are also confronted increasingly confronted with infectious biofilms on them. The most most common implants are joint prostheses, osteosyntheses, vascular prostheses, pacemakers and defibrillators, dental implants, neurosurgical shunts and breast implants.

The success of treatment for implant infections depends on a precise precise, microbiological diagnosis. Because microorganisms form foreign bodies, they are often difficult to detect in the surrounding tissue. surrounding tissue.
Biofilms consist of an amorphous matrix of polymerised polysaccharide. polymerised polysaccharide in which microorganisms are embedded. are embedded. In the biofilm, microorganisms are in a metabolically less active stationary growth phase. Over weeks to years a complex three-dimensional layer develops, which, via rudimentary the nutrition of the biofilm (via water channels) and its communication (via extracellular and its communication (through extracellular messengers). ensures.

While free-living (planktonic) bacteria are killed by antibiotics and the immune system, adherent immune system, adherent bacteria survive protected in the extra cellular in the extra cellular matrix of the biofilm.

Detection of biofilm-forming bacteria

The implant is aseptically removed from the body in the operating theatre and transported in a sterile box to the microbiology laboratory within 24 hours. After addition of Ringer's solution, the implant is shaken vigorously and exposed to ultrasound for 1 minute. The sonication removes > 99.9% of the adherent bacteria.

Quantitative detection of biofilm-forming bacteria

The sonicate is processed microbiologically and the amount of bacteria is quantified (number of colony-forming units per ml of sonication fluid. Sonication can detect up to 10,000 times more bacteria than conventional methods, such as biopsies of periprosthetic tissue. This makes it easier to detect mixed infections and different bacterial morphotypes. Sensitivity is improved, especially in patients with previous antibiotic therapy, because the bacteria protected in the biofilm survive better.
