Silent threat in hospitals: Pseudomonas aeruginosa feeds on medical plastics!

According to research, this deadly bacterium can digest a type of plastic called polycaprolactone (PCL), which is used in catheters, sutures and biodegradable implants. In laboratory experiments, the bacteria were observed to grow using this material as an energy source.

Pap1 Enzyme: The Power That Breaks Down Plastic

Scientists have determined that the bacteria produce a special enzyme called Pap1, which not only breaks down plastic but also allows the bacteria to multiply using the material as food.

Resistant Biofilms That Feed on Plastic

Pseudomonas aeruginosa forms protective layers called biofilms to protect itself from the immune system and antibiotics. Researchers have found that the bacteria develop larger and more resistant biofilms on plastic surfaces. Moreover, the degraded components of the plastic are integrated into the structure of the biofilm, increasing the resistance of the infection to treatment.

New Risks in Medical Devices

These findings are particularly concerning for the safety of plastic-based medical devices, such as catheters, orthopedic implants and hydrogel pads used to treat burns. The researchers say bacteria can settle on these devices and break them down, compromising the success of treatment.

While it is emphasized that new measures should be taken for infection control in hospital environments, scientists state that more research should be done to prevent the spread of this bacteria.
