Complete genome sequences of epizootic hemorrhagic disease virus serotypes 5 and 6 isolated in Japan
AbstractHere, we report the complete genome sequences of epizootic hemorrhagic disease (EHD) virus serotypes 5 (EHDV-5) and 6 (EHDV-6) isolated in the Yaeyama Islands of Okinawa Prefecture, Japan. The EHDV-5 strain, ON-11/E/16, which was isolated in 2016, is, to our knowledge, the second EHDV-5 strain to be isolated after the first was isolated in Australia in 1977. In each of the genome segments, ON-11/E/16 was most closely related to EHDV strains of different serotypes isolated in Australia and Japan. Our results support the idea that various serotypes of EHDV have been circulating while causing reassortment in the Asia-...

Isolation and characterization of three novel Acinetobacter baumannii phages from Beninese hospital wastewater
AbstractAcinetobacter baumannii is an opportunistic pathogen that is mostly associated with hospital-acquired infections. The rapid emergence of multi- and pan-drug-resistantAcinetobacter strains poses an increasing challenge in hospitals. Phage therapy offers one treatment option for infections caused byA. baumannii. We isolated three phages from Beninese hospital wastewater – fBenAci001, fBenAci002, and fBenAci003 – that infected clinicalA. baumannii strains from Finnish patients. Phylogenetic analysis showed that these phages resemble phages of the genusFriunavirus, familyAutographiviridae. The isolated phages meet ...

Amesuviridae: a new family of plant-infecting viruses in the phylum Cressdnaviricota, realm Monodnaviria
AbstractThe phylumCressdnaviricota comprises viruses with single-stranded, circular DNA genomes that encode an HUH-type endonuclease (known as Rep). The phylum includes two classes, eight orders, and 11 families. Here, we report the creation of a twelfth family in the orderMulpavirales, classArfiviricetes of the phylumCressdnaviricota. The familyAmesuviridae comprises viruses that infect plants and is divided into two genera:Temfrudevirus, including the speciesTemfrudevirus temperatum (with temperate fruit decay-associated virus as a member), andYermavirus, including the speciesYermavirus ilicis (with yerba mate-associated...

A novel narnavirus isolated from Colletotrichum curcumae strain 780-2T
AbstractThe complete genome of a novel mycovirus, Colletotrichum curcumae narnavirus 1 (CcNV1), derived from the phytopathogenic fungusColletotrichum curcumae strain 780-2T, was sequenced and analyzed. The full sequence of CcNV1 is 3,374 nucleotides in length and contains a single large open reading frame (ORF) encoding an RNA-dependent RNA polymerase (RdRp) of 1,087 amino acids with a molecular mass of 124.2 kDa that shares the closest similarity with that of Monilinia narnavirus H (53.02% identity). RdRp phylogeny analysis showed that CcNV1 is a new member of the proposed genus"Betanarnavirus" within the family...

Renaming of the genus Flavivirus to Orthoflavivirus and extension of binomial species names within the family Flaviviridae
AbstractThis review provides a summary of the recently ratified changes to genus and species nomenclature within the virus familyFlaviviridae along with reasons for these changes. First, it was considered that the vernacular terms “flaviviral”, “flavivirus”, and “flaviviruses” could under certain circumstances be ambiguous due to the same word stem “flavi” in the taxon namesFlaviviridae andFlavivirus; these terms could either have referred to all viruses classified in the familyFlaviviridae or only to viruses classified in the included genusFlavivirus. To remove this ambiguity, the genus nameFlavivirus was ...

Turnip yellows virus variants differ in host range, transmissibility, and virulence
This study was designed to test the hypothesis that three TuYV isolates, representing each of the Australian P5 variants, differ phenotypically. In particular, the host range, vector species, transmissibility, and virulence of isolates 5414 (P5-I5414), 5509 (P5-II5509), and 5594 (P5-III5594) were examined in a series of glasshouse experiments. Only P5-I5414 readily infected faba bean (Vicia faba), only P5-II5509 infected chickpea (Cicer arietinum), and only P5-I5414 and P5-III5594 infected lettuce (Lactuca sativa).Myzus persicae transmitted each isolate, butBrevicoryne brassicae andLipaphis pseudobrassicae did not. When us...

Isolation, characterization, and evaluation of putative new bacteriophages for controlling bacterial spot on tomato in Brazil
AbstractBacterial spot is a highly damaging tomato disease caused by members of several species of the genusXanthomonas. Bacteriophages have been studied for their potential use in the biological control of bacterial diseases. In the current study, bacteriophages were obtained from soil and tomato leaves in commercial fields in Brazil with the aim of obtaining biological control agents against bacterial spot. Phage isolation was carried out by co-cultivation with isolates ofXanthomonas euvesicatoria pv.perforans, which was prevalent in the collection areas. In a host range evaluation, none of the phage isolates was able to...
