Tissue distribution of a coliphage and Escherichia coli in mussels after contamination and depuration.

摘要: Experiments were undertaken to determine the tissue distribution of Escherichia coli and a coliphage after contamination common mussel (Mytilus edulis). Mussels contaminated with high levels feces-associated E. 22-nm icosahedral over 2-day period in flowing-seawater facility. After contamination, individual tissues carefully dissected assayed for coliphage. Contaminated mussels also analyzed contaminants 24- 48-h depuration periods. The majority each contaminant was located digestive tract (94 89% coliphage, respectively). Decreasing concentrations found gills labial palps, foot muscles, mantle lobes, hemolymph. Our results indicate that above water occurred only tract. depurated commercial-scale recirculating UV system period. percent reductions following order: tract, hemolymph, palps. different, occurring clearly demonstrate are differentially eliminated from two microorganisms at similar rates remaining tissues. show most significant retention 48 h is Thus, conventional practices inappropriate efficient virus elimination mussels.
