Antibiotic-Resistant Bacteria Digest Medical plastics, Raising Infection Fears
Table of Contents
LONDON – October 27, 2024 – A groundbreaking study published in *Cell* reveals that antibiotic-resistant bacteria can “digest” medical plastics. The research found that *Pseudomonas aeruginosa* bacteria, already a major cause of hospital-acquired infections, can now thrive on medical devices, potentially increasing the risk for patients globally. this discovery necessitates a reassessment of hospital sanitation protocols and infection control measures. The implications are critically important and require an immediate response to protect patient safety.
Antibiotic-Resistant Bacteria Found to ‘Digest’ Medical Plastics, Raising Hospital Infection Concerns
A groundbreaking revelation reveals that certain antibiotic-resistant strains of pseudomonas aeruginosa bacteria can “digest” medical plastics, according to research published in Cell. this finding has significant implications for hospital infection control and patient safety, as thes bacteria, already responsible for an estimated 559,000 deaths per year, can now possibly thrive on medical devices and implants.
The Plastic-Eating Bacteria
Researchers at Brunel University London made the startling discovery while examining bacteria isolated from a patient’s wound sample. They found that P. aeruginosa was able to survive and thrive on a specific type of plastic called polycaprolactone.
- Polycaprolactone: This plastic is widely used in various medical applications,including:
- Sewing yarns
- Stents
- Surgical nets
- Wound bandages
- Drug-bearing patches
- Implants
Implications for Hospital Environments
Ronan McCarthy of Brunel University described the research as a “worldwide first,” emphasizing the need to re-evaluate how pathogens spread within hospital settings. Plastics,especially plastic surfaces,can be a potential source of food for these bacteria. Pathogens wiht this ability can survive in hospital environments much longer,
McCarthy stated.
Increased Antibiotic Resistance
The study also revealed that digesting plastic leads to increased antibiotic resistance.McCarthy explained that the bacteria form a thicker protective outer layer, known as a biofilm, after consuming the plastic. This makes it difficult for the bacteria to become more resistant to antibiotics and to be treated,
he said.
A Call for Deeper Understanding
Given P. aeruginosa’s evolutionary history of adaptation, which spans approximately 200 years, the bacteria are adept at developing strategies to overcome scientific interventions. McCarthy stressed the importance of thoroughly understanding the effects of this newly discovered ability on patient safety. Plastic in modern medicine is everywhere,
McCarthy noted, underscoring the urgency of the situation.
Frequently Asked Questions
