A06

Groundwater serves as drinking water. Drinking water should be nonpathogenic, but each year we are faced with outbreaks originating from viruses in groundwater or surface water. Project A06 aims to show (i) that groundwater harbors one or two orders of magnitude more viruses than currently detected; (ii) a correlation between the bacterial and viral community and their nucleic adid modification signature; (iii) that viruses are infective without the host for more than two months; (iv) direct virus-host interaction; and to (v) develop a high-throughput pipeline for multiple bacteria simultaneously.
