| non-polio enterovirus activity in wisconsin based on a 20-year experience in a diagnostic virology laboratory. | laboratory test results, demographic information, and clinical data on 1364 patients who had specimens submitted to the wisconsin state laboratory of hygiene and from whom non-polio enteroviruses were isolated during 1957--1976 were examined. echoviruses (echo) and coxsackievirus group b (cb) and group a (ca) were isolated from 719, 389, and 256 of the patients, respectively. thirty-five different serotypes were identified in the 20-year period. the six most frequently occurring serotypes (echo ... | 1979 | 222136 |
| echovirus 11 infections of newborns with mortality during the 1979 enterovirus season in milwaukee, wis. | echovirus serotype 11 (echo-11) was implicated in three neonatal deaths during an enterovirus outbreak from july through october 1979 in milwaukee. the deaths followed congenital infections acquired in the community during late pregnancy. two of the three echo-11 and one coxsackie b4 deaths of infants occurred after cesarean section deliveries. of 225 confirmed echovirus infections, 30 to 45 percent occurred in infants under 60 days old, 54 to 67 percent in the first year of life, and 13 to 25 p ... | 1982 | 6287514 |
| human enteric viruses in groundwater from a confined bedrock aquifer. | confined aquifers are overlain by low-permeability aquitards that are commonly assumed to protect underlying aquifers from microbial contaminants. however, empirical data on microbial contamination beneath aquitards is limited. this study determined the occurrence of human pathogenic viruses in well water from a deep sandstone aquifer confined by a regionally extensive shale aquitard. three public water-supply wells were each sampled 10 times over 15 months. samples were analyzed by reverse tran ... | 2007 | 17948815 |
| concentration of enteroviruses, adenoviruses, and noroviruses from drinking water by use of glass wool filters. | available filtration methods to concentrate waterborne viruses are either too costly for studies requiring large numbers of samples, limited to small sample volumes, or not very portable for routine field applications. sodocalcic glass wool filtration is a cost-effective and easy-to-use method to retain viruses, but its efficiency and reliability are not adequately understood. this study evaluated glass wool filter performance to concentrate the four viruses on the u.s. environmental protection ... | 2008 | 18359827 |
