Pseudomonas aeruginosa in swimming pools related to the incidence of otitis externa infection.

Abstract

A study is reported which demonstrates that four out of twenty-four people developed otitis externa as a result of swimming in a pool with a high incidence of Pseudomonas aeruginosa. Serotyping and phage typing were used to establish that P. aeruginosa was the etiolgoical event responsible for the outbreaks of the infection.
