Adsorption-Elution Techniques and Molecular Detection of Enteric Viruses from Water

Submit Manuscript | http://medcraveonline.com in drinking water. Faecal coliforms are used as indicators because of the assumption that the fate and transport of faecal coliforms reflect that of the waterborne pathogens [1]. However, accumulating evidence on waterborne disease outbreaks shows that absence of faecal coliform indicators does not entirely eliminate possibilities of the presence of other pathogens with a potential to cause disease outbreaks [2]. For example some enteric viruses are resistant to many disinfectants and remain viable after disinfection [3]. Studies have also demonstrated that there is no relationship between current bacterial indicator detection and the presence of viruses in treated water [4]. There is therefore need to have multiple or supplementary indicators which include enteric viruses and if possible to directly monitor the levels of viral pathogens in surface waters, irrigation water, sewage effluent as well as treated drinking water for public health safety and quality assessment [5]. However due to the low concentration of viruses in water matrices and presence of inhibitors, efficient concentration methods from large quantities are essential [5,6].
