摘要: Urban estuaries throughout the world typically contain elevated levels of faecal contamination, extent which is generally assessed using indicator organisms (FIO) such as Escherichia coli. This study assesses whether bacterial FIO, E. coli a suitable surrogate for Campylobacter spp., in estuaries. The presence and survival dynamics culturable spp. are compared water column, bank sediments bed Yarra River estuary (located Melbourne, Australia). did not necessarily indicate detectable sediments, but inactivation rates two bacteria were similar column. A key finding that can survive up to 14 days column 21 days estuary. Preliminary data presented this also suggests may be sediments. undermines previous hypotheses cannot outside its host indicates public health risks persist aquatic systems three weeks after initial contamination event.
