Occurrence of Escherichia coli, noroviruses, and F-specific coliphages in fresh market-ready produce.
Forty samples of fresh produce collected from retail food establishments were examined to determine the occurrence of Escherichia coli, F-specific coliphages, and noroviruses. An additional six samples were collected from a restaurant undergoing investigation for a norovirus outbreak. Nineteen (48%) of the retail samples and all outbreak samples were preprocessed (cut, shredded, chopped, or pee...
متن کاملF-specific RNA coliphages: occurrence, types, and survival in natural waters.
A small, well-defined watershed was investigated over a 2-year period to determine the prevalence of F-specific RNA coliphage (F + RNA) serotypes as indicators of animal fecal contamination. Sampling sites collected runoff from areas of urban and agricultural land use patterns. F-specific coliphages were concentrated from 2-L freshwater samples by polyethylene glycol precipitation, isolated usi...
متن کاملSlow-sand water filter: Design, implementation, accessibility and sustainability in developing countries

The global water crisis not only has severe medical implications, but social, political, and economic consequences as well. The Institute of Catholic Bioethics at Saint Joseph's Univ...
متن کاملA comparison of the survival of F+RNA and F+DNA coliphages in lake water microcosms.
The survival of seven F+RNA phages (MS2 Group I ATCC type strain, two Group I environmental isolates, a Group II environmental isolate, a Group III environmental isolate, and two Group IV environmental isolates) and six F+DNA phages (M13, fd, f1, and ZJ/2 ATCC type strains, and two environmental isolates) were examined in microcosms using a surface drinking water source. Phages were spiked into...
