| waterborne giardiasis: a communitywide outbreak of disease and a high rate of asymptomatic infection. | a communitywide outbreak of gastrointestinal illness due to giardia lamblia infection occurred in the city of berlin, new hampshire, during april and may 1977. the clinical, epidemiologic, and laboratory aspects of this outbreak are described here. in 213 predominantly symptomatic cases of g. lamblia infection diagnosed at a local hospital laboratory in a 6-week period, illness was characterized by prolonged diarrhea (median duration 10 days) and 13% of symptomatic infections required hospitaliz ... | 1980 | 7424899 |
| electron microscopy of giardia lamblia cysts. | the flagellated protozoan giardia lamblia is a recognized public health problem. intestinal infection can result in acute or chronic diarrhea with associated symptoms in humans. as part of a study to evaluate removal of g. lamblia cysts from drinking water by the processes of coagulation and dual-media filtration, we developed a methodology by using 5.0-microns-porosity membrane filters to evaluate the filtration efficiency. we found that recovery rates of g. lamblia cysts by membrane filtration ... | 1980 | 7425627 |
| intestinal parasites in southeast-asian refugees. prevalence in a community of laotians. | in response to public concerns, 165 meo laotians had stools screened for intestinal parasites by the illinois department of public health. one hundred twenty-nine had at least one pathogenic parasite detected. hookworm was detected most frequently, followed by giardia lamblia, trichuris trichiura, and ascaris lumbricoides. hookworm and overall infection were more frequent in persons 4 years of age and older, while giardiasis, ascariasis, and trichuriasis were most common in the 4- to 14-year age ... | 1980 | 7431591 |
| vitamin a concentration in children with giardiasis. | although the vitamin a concentration was somewhat lower in patients with giardiasis than in normal children this difference was not significant; 35% of patients with giardiasis and 22.6% of normal children had vitamin a concentration lower than 20 micrograms/dl. this indicates that there may be malabsorption of vitamin a and that low serum vitamin a levels may be found in patients who were infected with giardia lamblia. therefore, apart from antigiardia agent, supplementation of vitamin a should ... | 1980 | 7434075 |
| giardiasis in infancy diarrhoea. | of 435 infants with diarrhoea aged under one year, 6% were found to have giardia lamblia; the incidence ranged from 3% housed infants to 12% in itinerant infants. all infants had duodenal fluid and faeces examined. infants under 12 weeks may experience severe diarrhoea in association with infection by this parasite, but seem more likely to respond to metronidazole than older infants. | 1980 | 7436537 |
| intestinal parasitic infections in homosexual men: prevalence, symptoms and factors in transmission. | in a controlled study 67.5% of 200 homosexual men but only 16% of 100 heterosexual men were found to be infected with intestinal parasites. entamoeba histolytica was isolated from 27% of the homosexual and 1% of the heterosexual men, and giardia lamblia was isolated from 13% of the homosexual and 3% of the heterosexual men. the presence of symptoms could not be correlated with infection except when the infection was caused by more than one organism, including g. lamblia. symptoms were much more ... | 1980 | 7437971 |
