Sputum samples submitted to the microbiology laboratory from general medical and respiratory wards were monitored for Moraxella catarr halis on a prospective basis.
All isolates were typed by restriction endonuclease typing.
Nosocomial spread was found both by the clustering of cases and typing of isolates.
Sampling of the environment of some cases was performed.
Seven out of 3 7 samples revealed environmental contamination.
Sampling for persistence of the organism in the environment was positive on one occasion out of 13.
Evaluation of acquisition of M. catarrhalis in relation to length of stay showed that the average length of stay of a case with M. catarrhalis was considerably longer than average patient stay without M. catarrhalis.
Four patients had two isolates available for typing.
