Antibiotic-resistant bacteria represent an increasing concern in wound infections.    

The Problem:

Chronic wounds caused by vascular insufficiency often show multiple bacterial strains which are resistant to common antibacterials.  The recent spread of fluoroquinolone resistant E. coli, extended spectrum beta-lactamase (ESBL), methicillin-resistant Staphylococcus aureus (MRSA), and vancomycin-resistant enterococci (VRE), among other emerging bacterial resistance factors contributes to increasing treatment cost and poor patient outcomes.

A New Tool in Wound Care and the Fight Against Antimicrobial Resistance:

MicroPathID – Wound Pathogen Panel (WPP)Uses real-time PCR to identify and quantify 17 pathogenic bacteria and fungal species associated with wound infections and detects of up to 36 genes that confer antibiotic resistance across 10 drug classes.  Confirmatory wound culture and susceptibility results are also provided to help guide antibiotic selection and assist with antimicrobial stewardship.

Confirmatory Culture
and Susceptibility

Antibiotic Susceptibility

Conventional Cultures:

  • Are unable to produce growth in certain pathogens
  • Require 48-72 hours for results

Clinical Advantages:  MicroPathID – WPP Panel

  • Rapid PCR results on pathogen identification and antibiotic resistance
    • 12 – 24 hours from specimen receipt
  • Improved Sensitivity
    • 3-5X more sensitive than conventional culture
  • Can detect polymicrobial infections
  • Unaffected by concurrent antibiotic use
  • Culture confirmation and susceptibility
    • Phenotypic characterization combined with genotypic information for improved outcomes

The Process

The Wound Pathogen Panel is performed by by Poplar Healthcare from a swab specimen collected in a BD ESwab media (liquid Amies).

Day 1
Collect wound swab sample

Day 2
Specimen arrives at Poplar Healthcare – PCR testing and cultures begin

Day 2-3
Receive PCR results of 17 pathogens and Antibiotic Resistance Genes

Day 4
Receive confirmatory culture and susceptibility results

Day 4
Informed antibiotic selection
