Abstract

BACKGROUND:

The emergence and rapid spread of multidrug-resistant isolates causing nosocomial infections, particularly pandrug-resistant Acinetobacter baumannii, pandrug-resistant Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus, and extended-spectrum beta-lactamase-producing Enterobacteriaceae are of great concern worldwide.

METHODS:

This study investigated the efficacy of pasteurization against contamination of culture tubes and plastic bags by the above 4 important multidrug-resistant bacteria. A 5-mL bacterial suspension with approximately 10(5) and 10(9) cfu/mL of each organism was inoculated into 3 sets of plastic bags and culture tubes and subjected to pasteurization in a washer at 75 degrees C for 30 minutes.

RESULTS:

A nearly total eradication was found after pasteurization of these 4 drug-resistant pathogens.

CONCLUSION:

Pasteurization was highly effective against drug-resistant bacteria. Strict adherence to appropriate infection control management for respiratory circuits is important for reducing the spread of drug-resistant bacteria among ventilator-assisted patients.
