EPIDEMIOLOGY OF PSEUDOMONAS AERUGINOSA INFECTION IN HOSPITALS: 2. “FINGERPRINTING” OF PS. AERUGINOSA STRAINS IN A STUDY OF CROSS–INFECTION IN A CHILDREN'S HOSPITAL

Abstract
Pyocine typing of Pseudomonas æruginosa proved to be a useful epidemiological marker to indicate cross‐infection in a pædiatric hospital. Serotyping and phage typing provided additional subdivisions of the pyocine types. It was shown that patients with symptoms of infection or carriers, and also inanimate objects in a ward environment provided an infective reservoir, and that contaminated hands of nurses could contribute to the spread of infection.
