Abstract

During the 1989 calendar year, P. aeruginosa caused clinical infections in 0.46% of patients admitted to Ospedali Riuniti (a general hospital), Bergamo, Italy. Strains (n=267) of P. aeruginosa were collected during this period, and epidemiological characteristics were studied. The mean prevalence of P. aeruginosa infection in inpatients was 1.1% (range 0.06-7.3), whereas outpatients showed a significantly lower prevalence of infection (0.05%). Strains were recovered from inpatients of surgical wards (n=126; 47.2%), and outpatients (n=15; 5.6%). Males were more often affected than females (2.7:1). Infection of the urinary tract was the most common (34.1%). Pseudomonas aeruginosa was also involved in lower respiratory tract infections (18.7%) and septicaemia (17.6%). Four typing methods were performed, i.e. serotyping, antibiotyping, pyocin typing, and restriction endonuclease analysis (REA). Serotypes 0:11 and 0:6 were endemic in the hospital. Some serotypes correlated with specific clinical wards. Pyocin typing was an unreliable epidemiological tool. However, antibiotyping showed the presence of some epidemic clusters, probably related to the antibiotic consumption of the patients. REA suggested the circulation of endemic P. aeruginosa strains in both the obstetrics and neurosurgery wards.
