| hot tub legionellosis. legionnaires' disease and pontiac fever after a point-source exposure to legionella pneumophila. | legionella pneumophila is associated with outbreaks of either pontiac fever, a self-limited influenzalike condition without pneumonia, or legionnaires' disease, a severe pneumonic disease affecting elderly or immunocompromised individuals. an outbreak of both legionnaires' disease and pontiac fever after a point-source exposure to l pneumophila was studied. our observations demonstrated the spectrum of illness that l pneumophila may cause and emphasized the importance of host factors in affectin ... | 1993 | 8239853 |
| legionnaires' disease: the epidemiology of two outbreaks in burlington, vermont, 1980. | eighty-five cases of legionnaires' disease were diagnosed in two major outbreaks at a large regional medical center in burlington, vermont, in the summer of 1980. cases in both outbreaks were positive for legionella pneumophila, serogroup 1 by culture, serology, or direct fluorescent antibody tests. all cases had spent time in the city of burlington in the 10 days before the onset of symptoms. cases in both outbreaks were both hospital- and community-acquired. a case-control study identified no ... | 1984 | 6702814 |

| legionnaires' disease in vermont. 1972-1976. | one hundred four autopsy cases with previously diagnosed pneumonitis were examined for evidence of legionnaires' disease. the peak epidemic months of july, august, and september in the five years before the 1977 vermont epidemic were chosen for study. the bacterium, legionella pneumophila (serogroup 1) was demonstrated in lung tissue by direct immunofluorescence and the dieterle silver impregnation stain. there was no clustering of legionnaires' disease in any one year., the clinical presentatio ... | 1981 | 7315798 |
| pontiac fever associated with a whirlpool spa. | in march 1981, an outbreak of 34 cases of pontiac fever occurred among 74 members of a social club who visited an inn in south-central vermont. environmental and epidemiologic investigations were done to identify the causes of the illness. the outbreak of pontiac fever was most likely caused by l. pneumophila, serogroup 6, which was identified in a whirlpool spa at the inn. this is the first reported instance of an outbreak of pontiac fever associated with a whirlpool spa. | 1984 | 6391156 |
| correlation of subtypes of legionella pneumophila defined by monoclonal antibodies with epidemiological classification of cases and environmental sources. | twenty-five clinical isolates of legionella pneumophila serogroup i were classified as epidemic or sporadic on epidemiological grounds. all were isolated from patients at the medical center hospital of vermont (mchv) in burlington between 1977 and 1983. these coded isolates were examined with a panel of eight monoclonal antibodies to serogroup 1 and an indirect microimmunofluorescent test. strains from 14 of the 15 mchv epidemic cases had one staining pattern (a); isolates from eight of nine mch ... | 1984 | 6386999 |
| legionella in cooling towers. | legionellosis (legionnaires' disease and pontiac fever) outbreaks have been associated with aerosols ejected from contaminated cooling towers--wet-type heat rejection units (wthrus) used to dissipate unwanted heat into the atmosphere. the vermont department of health undertook a program to inventory, inspect, and sample all wthrus in vermont from april 1981 to april 1982. all wthrus were sampled for legionella pneumophila and data were obtained for location, design, construction, and operating c ... | 1986 | 10281778 |
