persistence of legionella pneumophila in a hospital's water system: a 13-year survey. | to describe the molecular epidemiology of legionella pneumophila infections in the university of iowa hospitals and clinics (uihc). | 1999 | 10614601 |
legionnaires' disease among pneumonias in iowa (fy 1972-1978) ii. epidemiologic and clinical features of 30 sporadic cases of l. pneumophila infection. | we reviewed retrospectively the clinical records of 30 cases of sporadic legionella pneumophila infection that occurred in iowa between fy 1972 and 1978. cases occurred throughout the year, most between may and december. twenty-one male patients and 9 female patients ranging in age from 5-80 years were infected. half the patients smoked or had an underlying illness; five were receiving corticosteroids or immunosuppressive therapy. occupations and exposures related to hospitals, construction and ... | 1981 | 7468637 |
legionnaires' disease associated with a hospital water system. a five-year progress report on continuous hyperchlorination. | in 1981, sixteen cases of nosocomial legionellosis occurred among 456 patients admitted to a new hematology-oncology unit (35 per 1000 admissions). monoclonal antibody typing and restriction endonuclease plasmid analysis identified a unique strain (09,04) of legionella pneumophila serogroup 1 isolated from both patients and water outlets. continuous hyperchlorination of the hot and cold water began in january 1982, and chlorine levels of 3 to 5 mg/l have been maintained most recently. water samp ... | 1988 | 3352131 |
the application of molecular and immunologic techniques to study the epidemiology of legionella pneumophila serogroup 1. | we applied monoclonal antibody typing and restriction endonuclease analysis of plasmid dna to study 28 clinical and 35 environmental (potable water) isolates of legionella pneumophila serogroup 1 from three hospitals in iowa between 1981 and 1986. monoclonal antibody typing employed a panel of seven antibodies and delineated eight different subtypes. plasmids were present in 57% of the isolates including 12 of 28 (43%) clinical and 25 of 35 (69%) potable water isolates. the plasmids ranged in si ... | 1989 | 2591166 |
