Bacterial biofilm-based catheter-associated urinary tract infections: Causative pathogens and antibiotic resistance

General virus

The American Journal of Infection & Control have published a very interesting paper, ‘Bacterial biofilm-based catheter-associated urinary tract infections: Causative pathogens and antibiotic resistance’ in which the authors demonstrate very high levels of biofilm formation in all catheters but these vary on catheter type:

Highlights

  • •Biofilm based catheter associated urinary tract infection is now an emerging problem.
  • •Biofilm production is greatly influenced by male gender, increased duration of catheterization and by use of latex catheter.
  • E.coli is the most common isolate of CAUTI but Enterobacter cloacae exhibit highest biofilm production.
  • •High antibiotic resistance observe in biofilm producing strains due to slow penetration, resistant phenotype and altered micro environment.
  • •Good infection control policies and antibiotic stewardship are needs of hour.

Conclusion

Biofilm-based CAUTI is an emerging problem. E coli was the most frequent isolate. High antibiotic resistance was observed in biofilm-producing strains. Using the variables affecting biofilm formation, tailored intervention strategies can be implemented to reduce biofilm-based CAUTIs.
