[Multi-Drug-Resistant Pseudomonas Aeruginosa].

Infection control is one of the most important measures for the safety of medical treatment. The microbiology unit of the clinical laboratory is the first defense against nosocomial infection. Our infection control team belongs to the clinical laboratory and our infection control practices are based on the accessibility of microbiology data. We have learned lessons from 2 outbreaks of multi-drug-resistant Pseudomonas aeru- ginosa in the past and have established the current surveillance system for multi-drug-resistant organisms in our hospital. In this article, I describe how we can utilize laboratory data for an effective infection control strategy and how the laboratory department can contribute to infection control practice. [Review].
