AbstractThree phages targeting Pseudomonas syringae GAW0113 have been isolated from organic waste samples: Pseudomonas phage Bertil, Misse and Strit. The phages have double-stranded DNA genomes ranging from 41342 to 41374 bp in size comprising 50 to 51 open reading frames. The three phages genomes are highly similar and genomic comparison analyses shows that they all belong to the Autographivirinae subfamily of the family Podoviridae. The phages are however only distantly related to other members of this family, and have limited gene synteny with type-phages of other genera within Autographivirinae, suggesting that the newly isolated phages could represent a new genus.

The freshwater fish Lepomis macrochirus (bluegill) is common to North American waters, and important both ecologically and as a sport fish. In 2001 an unknown virus was isolated from bluegills following a bluegill fish kill. This virus was identified as a picornavirus [termed bluegill picornavirus (BGPV)] and a diagnostic reverse transcriptase PCR was developed. A survey of bluegills in Wisconsin waters showed the presence of BGPV in 5 of 17 waters sampled, suggesting the virus is widespread in bluegill populations. Experimental infections of bluegills confirmed that BGPV can cause morbidity and mortality in bluegills. Molecular characterization of BGPV revealed several distinct genome characteristics, the most unusual of which is the presence of a short poly(C) tract in the 3′ UTR. Additionally, the genome encodes a polyprotein lacking a leader peptide and a VP0 maturation cleavage site, and is predicted to encode two distinct 2A proteins. Sequence comparison showed that the virus is most closely related to a phylogenetic cluster of picornaviruses that includes the genera Aquamavirus, Avihepatovirus and Parechovirus. However, it is distinct enough, for example sharing only about 38 % sequence identity to the parechoviruses in the 3D region, that it may represent a new genus in the family Picornaviridae.

The genus Mamastrovirus belongs to the family Astroviridae and consists of at least six members infecting different mammalian hosts, including humans, cattle and pigs. In recent years, novel astroviruses have been identified in other mammalian species like roe deer, bats and sea lions. While the bovine astrovirus was one of the earliest astroviruses to have been studied, no further research has been performed recently and its genome sequence remains uncharacterized. In this report, we describe the detection and genomic characterization of astroviruses in bovine faecal specimens obtained in Hong Kong. Five of 209 specimens were found to be positive for astrovirus by RT-PCR. Two of the positive specimens were found to contain sequences from two different astrovirus strains. Complete genome sequences of approximately 6.3 kb in length were obtained for four strains, which showed similar organization of the genome compared to other astroviruses. Phylogenetic analysis confirmed their identities as members of the genus Mamastrovirus, and showed them to be most closely related to the Capreolus capreolus astrovirus. Based on the pairwise genetic distances among their full-length ORF2 sequences, these bovine astroviruses may be assigned into at least three different genotype species. Sequence analysis revealed evidence of potential recombination in ORF2. In summary, we report the first genome sequences of bovine astroviruses and clearly establish the species status of the virus. Additionally, our study is among the first to report co-infection by different astrovirus genotypes in the same host, which is an essential step for recombination to occur.
