Working principle of the BactoSonic
The implant is placed in the liquid of the corresponding box and then placed in the specially designed BactoSonic ultrasonic bath. 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.
Technical details can be found in the Data sheet.

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.

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.
