Presence of Human and Animal Viruses in Surface Waters in Vojvodina Province of Serbia.

ABSTRACT

For the first time in Serbia, a small surveillance study was conducted in order to estimate the presence and frequency of occurrence of selected human [adenoviruses (HAdV), noroviruses, (NoV GI, NoV GII) and hepatitis A virus (HAV)], animal [porcine adenovirus (PAdV) and bovine polyomavirus (BPyV)] and zoonotic [hepatitis E virus (HEV)] viruses in selected surface waters. In total, 60 surface water samples were collected in two sampling occasions at 30 locations, with each sampling time being separated by 1-5 months. In addition, six sewage effluent samples were collected at one sampling site per each of the three tested town sewage systems, in two sampling occasions with 2 months intervals, before their discharge into the surface waters. The most prevalent virus found was HAdV which was detected in 43.33 % samples. NoV GII was found in 40 % samples. NoV GI was found in 10 % samples, and PAdV, BPyV and HEV were detected in 5 (8.33 %), 4 (6.67 %) and 2 (3.33 %) samples, respectively. HAV was not found in any of analysed surface waters or urban sewage samples. The obtained results confirm the presence of pathogenic enteric viruses of both human and animal origin in surface waters in Serbia indicating the existence of diverse contamination sources.
