5 Abstract This study aims to determine the suitable indicators of viruses. The detection rate and correlation between candidate microorganisms including coliphages and viruses in water environment were investigated Coliphages stem from faeces of humans or warm-blooded animals and preferably not be able to multiply in water environment. The major advantage of coliphages, compared with viruses, is that they are detectable by simple, inexpensive and rapid techniques. Also they share many fundamental properties and features like structure, composition, morphology, size and site of replication etc. Most of 46 water samples(ground water 32, river 14) were identified as genotype GII-4 norovirus. Specific genotype were GII Jeju-4, GII Jeju-14 and GII YURI. Microbial detection rate of 46 water samples were as follows; somatic phage accounted for the highest rate(31 samples, 67.4%), followed by total coliform(30, 65.2%) male-specific phage(20, 43.5%), E.coli(19, 41.3%), norovirus(9, 19.6%) and enterovirus(5, 10.9%). E.coil(EC), male-specific phage with E.coli(MP_EC) and phage with E.coli(MP_EC) showed the high detection rate simultaneously with viruses. The detection of viruses was correlated with male-specific phage with E.coil(MP_EC), somatic phage with E.coli(SP_EC),and E.coli. These results suggest that suitable virus indicators were male-specific phage with E.coli(MP_EC), followed by somatic phage with E.coli(SM_EC) and two phages with E.coli(P_EC).
