Abstract:
:This study aimed to evaluate the contamination level of the Peri Lagoon, the main freshwater reservoir of Santa Catarina Island, Southern Brazil, for human adenovirus (HAdV), hepatitis A virus (HAV), rotavirus species A (RVA), and somatic coliphages (SOMCPH). Viruses were also investigated in sediments and their sensitivity against natural sunlight was analysed by studying their spatial distribution in different depths of the water column. A total of 84 water samples and 48 sediment samples were examined by qPCR or RT-qPCR. Infectivity of HAdV and SOMCPH was determined and quantified by plaque assay method. A sum of 64% and 48% of water and sediment samples were positive for HAdV, respectively. RVA was present in 33% and 18% of water and sediment samples, and 25% of water samples were positive for HAV. HAdV were infectious in 76% of water and 83% of sediment samples that were positive by qPCR. SOMCPH could be detected in 42% and 18% of water and sediment samples, respectively. The data pointed a variation of viruses' prevalence according to the different water column depths. These results demonstrated that water sources and sediments contaminated by human wastes could play an important role in the recontamination of water columns harvested for further treatment or used for recreational purposes. These data can be of great value for future risk assessment analysis.
