The diagnosis of chronic granulomatous disease was made for the first time in a young adult when he presented with Nocardia asteroides pneumonia. Treatment with trimethoprim/sulfamethoxazole for 10 wk brought about an apparent cure of the infection. Two and one half years later N. asteroides pneumonia recurred and resulted in death from respiratory failure. Antibiotic susceptibility studies suggested that both episodes were caused by the same organism. This suggestion was supported by endonuclease restriction analysis, which showed that the plasmids from both Nocardia isolates were identical. Late recurrence of pneumonia caused by N. asteroides occurs only rarely. In this patient, recurrent infection appeared to be related to persistence of colonizing organisms in the host.

Ten patients from a rehabilitation center were admitted to hospital with serious respiratory infections within ten weeks. An outbreak of Legionnaire's disease was suspected based on the epidemic and atypical manifestation of pneumonia and could be proven microbiologically. Pulmonary and extrapulmonary complications included respiratory failure, lung abscess, transitory renal impairment in five patients and acute renal failure requiring dialysis in one, tetraparesis caused by peripheral neuropathy and acute psychosis. Three patients died despite immediate institution of therapy with erythromycin. Legionella pneumophila serogroup 1 subtype Pontiac was isolated from a bronchial lavage sample of one patient and from the water supply of the rehabilitation center. Monoclonal antibody subtyping and restriction endonuclease analysis were performed on both environmental and patient isolates. Potable water was identified as the source of the outbreak based on identical patterns on restriction endonuclease analysis. Despite thermic and chemical disinfection with chlorination (up to 15 ppm) in the rehabilitation clinic, an eleventh case of Legionnaire's disease was detected 11 months later.

Nosocomial transmission of adenovirus type 3 associated with fatalities in infants has not been frequently reported. This report describes the nosocomial spread of adenovirus types 2 and 3 among infants with bronchopulmonary dysplasia in a chronic (transitional) care facility. The index case developed pneumonia with a clinical deterioration in respiratory status 8 days after admission. Within the next 10 to 30 days 9 other infants and 2 health care personnel became ill with respiratory symptoms. Three of these 10 infants had progressive respiratory failure and 2 of them died. All of these infants had underlying chronic lung disease of bronchopulmonary dysplasia. The overall attack rate was 30% (10 of 33). Further spread of adenovirus was prevented by using barrier precautions and masks while performing tracheostomy care. Adenovirus isolates were serotyped as Ad3 in 4 patients and 1 staff member, as Ad2 in 3 patients, and as a combination of Ad2 and Ad3 in 1 patient. Two fatalities were associated with Ad3 infection. Three isolates from 2 patients and 1 staff member were not available for typing. Restriction endonuclease analysis was performed on all of these isolates of Ad3 and Ad2. There was no genetic heterogeneity in the isolates, suggesting a common source.
