Effect of distance from the polluting focus on relative concentrations of Bacteroides fragilis phages and coliphages in mussels.
Concentrations of fecal bacteria, somatic and F-specific coliphages, and phages infecting Bacteroides fragilis in naturally occurring black mussels (Mytilus edulis) were determined.
Mussels were collected over a 7-month period at four sampling sites with different levels of fecal pollution.
Concentrations of both fecal bacteria and bacteriopbages in mussel meat paralleled the concentration of fecal bacteria in the overlying waters.
Mussels bioaccumulated efficiently, although with different efficiencies, all of the microorganisms studied.
Ratios comparing the levels of microorganisms in mussels were determined.
These ratios changed in mussels collected at the different sites.
