The genomes of a large number of highly diverse novel circular DNA viruses from a wide range of sources have been characterised in recent years, including circular single-stranded DNA (ssDNA) viruses that share similarities with plant-infecting ssDNA viruses of the family Geminiviridae. Here, we describe six novel circular DNA viral genomes that encode… (More)
Adsorption to aquifer media is an important process in the removal of viruses from groundwater. Even though hydrophobic interactions have been shown to contribute to adsorption, little is known about the hydrophobicity of viruses found in groundwater. In this study, the hydrophobicity of rotavirus, MS2 bacteriophage and DNA-labelled silica nanoparticles… (More)
Polyomaviruses are a family of DNA tumor viruses that are known to infect mammals and birds. To investigate the deeper evolutionary history of the family, we used a combination of viral metagenomics, bioinformatics, and structural modeling approaches to identify and characterize polyomavirus sequences associated with fish and arthropods. Analyses drawing… (More)
This article describes a rapid method for purifying infectious rotavirus particles from cell culture for environmental research. The method is based on size-exclusion chromatography using TOSOH TSKgel® G5000PWXL-CP with a TSKgel® Size Exclusion G2500PWxl guard column, set up on an AKTA Explorer10. Four peaks were identified from the chromatogram and the… (More)
The accurate detection of pathogens in environmental matrices, such as sediment, is critical in understanding pathogen fate and behavior in the environment. In this study, we assessed the usefulness of methods for the detection and quantification of Vibrio spp. and norovirus (NoV) nucleic acids in sediment. For bacteria, a commonly used direct method using… (More)
Implementation of a vector-enabled metagenomics approach resulted in the identification of various geminiviruses. We identified the genome sequences of Beet curly top Iran virus, Turnip curly top viruses, Oat dwarf viruses, the first from Iran, and Wheat dwarf virus from leafhoppers feeding on beet, parsley, pumpkin, and turnip plants.
The discovery and full-genome sequences of two isolates of a fourth capulavirus species are reported. The viruses were discovered during a viral metagenomics survey of uncultivated Plantago lanceolata plants in the Åland archipelago of south western Finland. The newly discovered viruses apparently produce no symptoms in P. lanceolata. They have a genome… (More)
Human enteric viruses are responsible for waterborne and shellfish-associated disease outbreaks worldwide. Quantitative reverse transcription PCR (qRT-PCR) is often used to assess the health risks associated with shellfish and environmental water, but viral titres in sediments are less commonly investigated. In this study, we developed and validated two… (More)
A diverse goose circovirus (GoCV) genome was recovered from a wild hunted greylag goose (Anser anser) in Poland. The genome shares 83% pairwise identity with other GoCV genomes recovered from various geese from China, Germany, and Taiwan.
The long term survival of fecal indicator organisms (FIOs) and human pathogenic microorganisms in sediments is important from a water quality, human health and ecological perspective. Typically, both bacteria and viruses strongly associate with particulate matter present in freshwater, estuarine and marine environments. This association tends to be stronger… (More)
