Enterovirus C96 (EV-C96) is a newer member of the species Enterovirus C. In this study, we determined the complete genome sequences of three EV-C96 isolates, one recovered from domestic sewage in 2013 and the other two isolated during surveillance of acute flaccid paralysis cases in 1991 and 2009, respectively. The complete genome sequences of these isolates were 75.6-84.2% identical to each other, 75.1-81.8% identical to the prototype strain, and 75.0-91.5% identical to other previously reported strains. Phylogenetic analysis of VP1 sequences revealed a high degree of genetic divergence among currently available EV-C96 sequences in the GenBank database, with an overall mean p-distance of 0...

Posaviruses and posa-like viruses are unclassified viruses with sequence similarity to viruses of the order Picornavirales. They have been reported in various vertebrates and invertebrates. We identified 11 posavirus-like sequences in porcine feces and performed phylogenic analysis. Previously reported Japanese posaviruses and those identified in this study clustered with posavirus 1, 4, and 7 and husavirus 1, while five viruses branched into three independent lineages, tentatively named posavirus 10, 11, and 12...

The complete nucleotide sequence of the viral protein 2 (VP2) ORF was determined for 26 Vietnamese infectious bursal disease isolates collected from clinical outbreaks in vaccinated flocks from 1987 to 2018 and two commercial vaccine specimens. These sequences were compared for molecular classification with 42 reference strains representing all four main classes of serotype 1, including very virulent (vvIBDV), classical (cvIBDV), antigenic variant (avIBDV) and attenuated (atIBDV) strains, and serotype 2 strains...

We previously obtained mouse-adapted variants of H1N2 avian influenza virus that contained PB2-L134H, PB2-I647L, PB2-D701N, HA-G228S, and M1-D231N mutations. Here, we analyzed the effects of these mutations on viral pathogenicity in a mammalian model. By evaluating the virulence of mouse-adapted H1N2 variants at different generations, we found that the PB2-D701N and HA-G228S mutations both contribute to the virulence of this virus in mammals. Furthermore, we found that the PB2-D701N and HA-G228S mutations both enhance the ability of the virus to replicate in vivo and in vitro and that the PB2-D701N substitution results in an expansion of viral tissue tropism...

We identified two novel circoviruses, HK02976 and HK00220, in oral swabs from bats. The size of their full genome was 2,010 nucleotides (nt). The full-genome sequence of our strains shared 96.1% nucleotide sequence identity with each other, and 39.9%-69.5% identity with bat-associated circoviruses (BatACVs)1-9. Based on the species demarcation threshold for viruses of the family Circoviridae, which is 80% genome-wide nucleotide sequence identity, we have tentatively named this group of viruses "bat-associated circovirus 10" (BatACV10)...

Bacteria of the genus Raoultella are known to inhabit aquatic environments and can be found in medical samples. The pathogenicity of Raoultella ornithinolytica isolates in human has become increasingly important, and several cases of infections have been reported recently. However, there are no reports of isolation of bacteriophages infecting this bacterium. In this study, two novel phages (ISF3 and ISF6) of a methylotrophic Raoultella strain were isolated from sewage. To characterize the isolated phages, morphological features, protein profiles, restriction digestion patterns, and partial genome sequences were studied...

We previously found that genetic factors are associated with a familial predisposition for developing liver cirrhosis and hepatocellular carcinoma during chronic hepatitis B virus (HBV) infection. Autophagy has been shown to play a role in HBV replication and the course of disease. More than 190 host genes have been identified that modify the process of autophagy, but which of these genes are involved in chronicity of HBV infection and how this occurs remains unclear. Chronic hepatitis B (CHB) patients were recruited to investigate the expression of autophagy-modulating genes in peripheral blood mononuclear cells (PBMCs)...

Sweet potato chlorotic stunt virus (SPCSV; genus Crinivirus, family Closteroviridae), is an economically important pathogen of sweet potato. In the present work, the nucleotide sequences of two RNA segments of SPCSV (isolate SPCSV-UNB-01) were determined by MiSeq Illumina sequencing of samples of sweet potato plants grafted onto Ipomoea setosa. A comparative analysis of the genome organization of SPCSV-UNB-01 and other SPCSV sequences showed that RNA1 was lacking p22, and p5.1 and that p5.2. was absent in RNA2, indicating a unique genomic pattern...

We report here the annotation of the complete genomes of four novel lytic Staphylococcus phages; Stab20, Stab21, Stab22 and Stab23. These phages have double-stranded DNA genomes ranging between 153,338 and 155,962 bp in size with terminal repeats of 10,814-12,304 bp. The genome analysis suggests that they represent new phage species within the genus Kayvirus in the subfamily Twortvirinae of the family Herelleviridae.

Peste des petits ruminants (PPR) is a devastating disease that generally affects sheep and goats, mostly in Asia, the Middle East and Africa. The disease has been declared a target for global eradication. Despite its high prevalence in domestic flocks and its high seroprevalence among wildlife, it is rarely reported as a fulminant disease in wild ruminant species (with the exception of Central Asia). In this report, we describe a severe PPR outbreak in a zoo herd of Nubian ibex (Capra nubiana), causing the deaths of 2/3 of the herd...

Singapore grouper iridovirus (SGIV) is a lethal grouper virus containing 162 predicted ORFs. Previous proteomic studies led to identification of 73 SGIV structural proteins. Here, SDS-assisted tube-gel digestion and DOC-assisted in-solution digestion coupled with LC-ESI-MS/MS were applied to further profile the SGIV structural proteome. We identified a total of 90 SGIV structural proteins including 24 newly reported proteins. Additionally, several PTMs were identified, including 26 N-terminal acetylated proteins, three phosphorylated proteins, and one myristoylated protein...

Introduction of animal group A rotavirus (RVA) gene segments into the human RVA population is a major factor shaping the genetic landscape of human RVA strains. The VP6 and NSP4 genes of 74 G/P-genotyped RVA isolates collected in Rawalpindi during 2010 were analyzed, revealing the presence of VP6 genotypes I1 (60.8%) and I2 (39.2%) and NSP4 genotypes E1 (60.8%), E2 (28.3%) and E-untypable (10.8%) among the circulating human RVA strains. The typical human RVA combinations I1E1 and I2E2 were found in 59.4% and 24...

Using next-generation sequencing to characterize agents associated with a severe stunting disease of parsley from Germany, we identified a hitherto undescribed virus. We sequenced total RNA and rolling-circle-amplified DNA from diseased plants. The genome sequence of the virus shows that it is a member of the genus Nanovirus, but it lacks DNA-U4. In addition to the seven genomic DNAs of the virus, we identified a second DNA-R and seven distinct alphasatellites associated with the disease. We propose the name "parsley severe stunt associated virus" (PSSaV) for this novel nanovirus...

Schmallenberg virus is an orthobunyavirus that infects ruminants and can cause transient fever, diarrhea, reduced milk production, congenital malformations, and abortions. Following the first suspected cases in Azerbaijan, a surveillance study was launched to determine and follow the situation. Serum samples and fetal tissue were collected starting October 2012 and tested via ELISA and qPCR. A first wave of Schmallenberg virus infections was detected in 2012/2013 in, and was largely limited to, the southern part of the country...

Numerous studies have shown that immunostimulatory complexes containing Quil-A saponin and various antigens are effective in stimulating the immune response and can be used as vaccine preparations for animals and humans. However, Quil-A saponin possesses toxicity and haemolytic activity. In the present work, a saponin-containing preparation named "Glabilox" was isolated from the roots of a Glycyrrhiza glabra L. plant by high-performance liquid chromatography (HPLC). The results showed that Glabilox has no toxicity or haemolytic activity and can form stable immunostimulatory complexes...

A new virus was identified in a celery plant showing chlorotic rings, mosaic and strong yellowing symptoms, and its complete genome sequence was determined. The genomic organization of this novel virus is analogous to that of known members of the genus Torradovirus, consisting of two single-stranded RNAs of 6,823 (RNA1) and 4,263 nucleotides (RNA2), excluding the poly(A) tails. BLAST searches against the nucleotide and protein databases showed that this virus is closely related to but different from carrot torradovirus 1 (CaTV1)...

Two large contigs with sequence similarities to different carlaviruses were identified by high-throughput sequencing in samples from a cactus plant. The complete genomes of the two viruses, tentatively named "cactus carlavirus 1" (CCV-1) and "cactus carlavirus 2" (CCV-2), were determined to be 8,441 and 8,396 nucleotides long, respectively, excluding the poly(A) tail. These viruses have the typical genomic organization of members of the genus Carlavirus. CCV-1 appears to be a cactus isolate of the carlavirus HSO-2016a, with 90...
