“…Similarly, Cornax et al (1991) suggested that in water with 10 2 -10 4 CFU/ml fecal coliforms the numerical relationship with coliphage is almost inexistent. These findings suggest that quantitative and/or qualitative assaying of phage may not represent the scenery of the enteric virus presence, inconsistent with the concept of phages as an indicator agent of fecal contamination (Amaral et al1994;Jurzik et al 2010). Adenovirus has been suggested as indicator of viral contamination, a part from enterovirus, because of its physicochemical stability and presents little seasonal variability.…”

“…From 1995 to 2000 outbreaks caused by norovirus or rotavirus were reported in Europe, 24% occurred in Finland, 17% in the Netherlands, 14% in Slovenia, 7% in Spain and 7% in England (Lopman et al 2003). According to Jurzik et al (2010) norovirus infected 344 and 1,699 people, respectively, in southern Italy and in Podgorica (Montenegro) due to contaminated water, and, additionally, 460 people were infected with enterovirus (EV) during an outbreak in the Republic of Belarus. In Brazil, Morillo et al (2008) also showed the importance of norovirus in waterborne infection.…”

“…Due to the difficulties of isolation and identification of virus in water, several studies have been conducted to find out a virus that can be used as an indicator of (viral) contamination (Jurzik et al 2010). It is known that bacteria have been used since the XIX century (Medema et al 2003) as indicators of fecal pollution in water, especially total coliforms and entecocci.…”

“…In addition, other investigations in Brazil, have also considered the use of enterovirus, rotavirus and adenovirus for this purpose (Dalla Vecchia et al 2012, Fongaro et al 2012, Fongaro et al 2013. Therefore, microorganisms other than E. coli, coliforms and enterococci (Jurzik et al 2010) have to be searched for to be elected as the most adequate indicator of animal virus in surface water.…”

The viral contamination of water for human consumption is a common cause of diseases outbreaks, therefore, a matter of great relevance for public health, especially in developing countries. In most countries, legislation recommends the study of coliforms to indicate the potability of water, however, this is not correlated with the presence of virus. The present review sought to characterize the epidemiological importance of waterborne viral diseases and the limitations of laboratorial detection and elimination of these pathogens. Besides, the state of art of virus as a tool to assess the quality of the water, as well as, the use of a single virus as the indicator of environmental contamination by virus itself are presented. Reports have demonstrated that some viruses are resistant to conventional water treatment process. Changes in water treatment policy should be achieved, and, should involve viral detection and resistance to physical and chemical agents, amongst other methods. However, we have to bear in mind that the decrease of waterborne infectious diseases is greatly dependent upon the improvement of sanitation, water treatment, together with preventive measures. All those measures together could ensure appropriate conditions for the promotion of human health and the reduction of environmental impacts.

“…These viruses are transmitted from person to person or through contaminated drinking water, food and bathing or recreational water (Rodriguez-Lazaro et al, 2012). The poor correlation of bacterial indicators with viruses is of particular concern because it cannot be used as reliable indicators of faecal pollution and viral particles in water (Jurzik et al, 2010, Chigor and Okoh, 2012and Carducci et al, 2013. Furthermore, enteric viruses were detected in raw, surface water, ground water and treated drinking water despite meeting quality standards for coliform bacteria (Cho et al, 2000 andPusch et al, 2005).…”

The fecal bacteria have been taken as the gold standard for water industry. However, the spread of viral gastroenteritis due to drinking water have given a momentum to a recent push by microbiologists to consider viruses as important pollution indicator as fecal bacteria. Therefore, we designed a study to evaluate the efficiency of two types of water purification systems: the traditional water treatment plant and two types compact units. Both systems produced drinking waters free of bacteria, chemical contaminants and mostly viruses free. However, recent advances in molecular biology techniques, such as RT-PCR have detected Rotaviruses in chlorinated drinking waters resulted from all systems. The frequency of Rotaviruses since October 2010 till September 2012 in Shark El-Mansoura WTP in drinking water samples was 12.5% similar to raw water. While the compact unit at Depo Awam (American design) the frequency of Rotavirus was 16.6% in both raw and drinking water samples. On the other hand the virus frequency in the raw and drinking water sample in El-Danabik unit (Egyptian design) were 12.5% and 4.16% respectively. Signifying failure of the chlorination process in removing viruses completely. However, detection of Rotavirus genome in the drinking water samples does not means the presence of its infectivity. The infectious ability of the rotaviruses was confirmed by CC-RT-PCR in all positive samples, where viral RNA was not detected in the collected drinking water samples. In conclusion RT-PCR and CC-RT-PCR techniques high lightened the need to include viruses as mandatory pollution indicator in water treatment plants. Int J Appl Sci Biotechnol, Vol 3(3): 528-536
