Assessment of Torque Teno Virus as a Viral Pathogen Indicator in Waters [Project #4288]
نویسندگان
چکیده
For the past century, public health officials have relied on fecal coliforms to identify and track bacterial contamination. However, several issues arise when using coliforms as indicators for viral pathogen risk. First, there is a lack of association between fecal coliforms and human enteric viruses in the environment. Second, there are differences in the fate of coliforms compared to viral pathogens in surface and groundwater systems. Lastly, the relative resistance of coliforms compared to viral pathogens through engineered treatment processes is not comparable for all viruses and all treatment options. Despite the potential public health implications, a suitable viral pathogen indicator has yet to be established. Recent research in the drinking water community has focused on modifying coliform monitoring methods or assessing bacteriophages as indicators. There is less current research to develop new, reliable indicator systems for viral pathogen risk. The proposed viral pathogen targets, norovirus and adenovirus, have demonstrated seasonal variations in prevalence. Considering analyst safety, indicator systems remain the best means of assessing pathogen risk. With advances in molecular techniques applied to environmental monitoring, improvements in indicator systems are timely. Therefore, the goal of this research was to examine the value of a potential new tool for assessing viral pathogen risk, specifically Torque teno virus (TTV).

Prevalence and Genotyping of Torque Teno Virus in HBV/HIV and Chronic HBV Patients in Iran
Background: Torque teno virus (TTV) was the first human Anelloviridae detected in a Japanese patient with an unknown type of hepatitis in 1997. TTV is by far the first known single-stranded circular DNA virus infecting human. In spite of its widespread nature in human population, its pathogenesis is still unclear. In addition, information regarding TTV infection in Iranian population is limited...
