Total coliforms are the most universally used indicator group, but include bacteria, in addition to Escherichia coil, that are not specifically associated with fecal pollution, i.e., Klebsiella spp., Citrobacter spp., and Enterobacter spp. Finding an appropriate indicator for the presence of enteric viruses, i.e., poliovirus, coxsackievirus A, coxsackievirus B, and echovirus [50, 147] , in sea water, is a vexing problem, especially for those responsible for regulating the use of sewage-contamined sites, including fresh, estuarine, and marine water and sediment, and shellfish harvested from these waters. Correlations between the number of fecal bacterial pathogens and indicator bacteria and their respective bacteriophages in fresh and marine water have been reported [185] .	./cache/cord-022947-ruizhgwh.txt	./txt/cord-022947-ruizhgwh.txt
