Rabbits are widely used as models in biological research, and the pathogen status of rabbits used in studies can directly affect the results of experiments. Serological surveillance is the common monitoring method used in laboratory animals. A rapid, sensitive, and cost-effective high-throughput Luminex xMAP assay could be an attractive alternative to labor-intensive enzyme-linked immunosorbent assay (ELISA) methods. In this study, recombinant proteins from rabbit hemorrhagic disease virus and rabbit rotavirus and whole viral lysates of Sendai virus were used as coating antigens in an xMAP assay for the simultaneous detection of antibodies against these pathogens...

A novel picornavirus, named "lorikeet picornavirus 1" (LoPV-1), was detected in a fecal sample from rainbow lorikeets using viral metagenomic analysis, and its complete genome sequence was determined and analyzed. The genome of LoPV-1 is 7862 nt long, including a 617-nt 5' UTR, a type IV IRES 5'UTR with an '8-like' motif, a 7032-nt polyprotein ORF, and a 213-nt 3' UTR. Phylogenetic analysis and pairwise asequence comparisons based on the amino acid sequences of P1, P2, and P3 indicated that LoPV-1 showed the closest relationship to two picornaviruses that were isolated recently from red-crowned cranes and clustered together with members of the genus Avihepatovirus...

Little is known about human parechovirus (HPeV) infection in Thailand. The genotype distribution of HPeV strains in children admitted to hospitals with acute gastroenteritis was investigated using polymerase chain reaction (PCR) and nucleotide sequencing of the VP1 region as the detection and genotype identification methods, respectively. Of a total of 2,002 stool samples, 49 (2.4%) were positive for HPeV. Of these, HPeV-1 was the most predominant genotype (40.8%), followed by HPeV-3 (16.3%) and HPeV-14 (16...

Two begomoviruses were isolated in the northern Brazilian state of Pará, infecting non-cultivated Hibiscus sp. and cultivated tomato (Solanum lycopersicum). The complete genomes (DNA-A and DNA-B) of the two viruses showed the typical organization of New World bipartite begomoviruses. Based on the species assignment criteria in the genus Begomovirus, each virus is a member of a new species. The virus from Hibiscus is most closely related to sida yellow mosaic Yucatan virus, while the tomato virus is most closely related to abutilon mosaic Brazil virus and corchorus mottle virus...

A new bipartite begomovirus (family Geminiviridae) was detected on cowpea (Vigna unguiculata) plants exhibiting bright golden mosaic symptoms on leaves under field conditions in Brazil. Complete consensus sequences of DNA-A and DNA-B components of an isolate of the virus (PE-088) were obtained by nanopore sequencing and confirmed by Sanger sequencing. The genome components presented the typical genomic organization of New World (NW) begomoviruses. Pairwise sequence comparisons revealed low levels of identity with other begomovirus species previously reported infecting cowpea around the world...

A potyvirus (isolate PFV-FJ) infecting passion fruit in China was identified by small-RNA sequencing. The complete genome sequence of PFV-FJ was determined to be 9974 nucleotides, excluding the poly(A) tail. PFV-FJ shares 70-72% nucleotide and 69-74% amino acid sequence identity at the polyprotein level with seven reported potyviruses, but 89% nucleotide and 91% amino acid sequence identity with an unreported potyvirus, tentatively named "passionfruit Vietnam potyvirus" (PVNV-DakNong). This suggests that PFV-FJ and PVNV-DakNong should belong to the same potyvirus species and that PFV-FJ is a new member of the genus Potyvirus...

Potato virus Y (PVY) is the most common virus infecting potato worldwide. We analysed potato tuber PVY infections from the major Israeli growing region in 2014-2017. Isolates were characterized by multiplex PCR according to Chikh-Ali et al. (Plant Disease 97, 1370, 2013), whose primers were not fully compatible with the Israeli isolates. New primers were designed for a multiplex PCR assay to differentiate the Israeli isolates. Three recombinant strains were observed: PVYNTNa (72% of the isolates), PVYNWi (24%) and PVYSyr-III (found only in 2015)...

Disease caused by bovine leukemia virus (BLV) results in significant economic losses to the livestock industry. To date, there is only one report describing the strains found in Italy. BLV strains (n = 24), collected between 2012 and 2016 from four different Italian regions, were genetically analyzed by direct sequencing of a portion of the BLV env gene, and the sequences were compared with those in the GenBank database. The Italian BLVs clustered into genotypes G2, G4, G6, G7, and G8, revealing a high level of BLV genetic heterogeneity in Italy...

Trypsin digestion promotes disassembly of GII.3 NoV virus-like particles (VLPs) and binding of VLPs to salivary histo-blood group antigens (HBGAs), but it is not clear which specific regions or residues mediate viral attachment to HBGAs. An earlier study indicated that arginine residues in the predicted surface-exposed loop region are susceptible to trypsin digestion. Here, we introduced single or multiple substitutions of four arginine residues located in the predicted surface-exposed loop region of the GII...

We describe an unexpected feature observed for the heterologous expression of the Thyrinteina arnobia cypovirus polyhedrin from a recombinant baculovirus infection in different insect cell lines. The in cellulo-formed crystals varied in size and shape depending on the cell line. Crystals formed in Trichoplusia ni-derived cells were cubic (0.1-2 μm) and localized in both the nucleus and cytoplasm, whereas those formed in Spodoptera frugiperda-derived cells were ovate and ellipsoidal (0.1-3 μm) and also localized in both the nucleus and cytoplasm...

West Nile virus (WNV) emerged in Greece in 2010 and since then human outbreaks occurred every year except 2015 and 2016. An early start and prolonged WNV transmission season was observed in 2018 with a record number of 316 reported cases and 47 fatalities. The Greek WNV strains detected during 2010-2018 clustered within the central European subclade of lineage 2. A novel WNV genetic variant was detected in August 2018 in one human case in the north-eastern region of Greece, at the land cross-border with Turkey and Bulgaria...

High-throughput sequencing revealed a tentative new badnavirus infecting Codonopsis lanceolata, provisionally named Codonopsis vein clearing virus (CoVCV). The complete 8,112-nt CoVCV genomic DNA sequence (GenBank accession: MK044821) comprises three open reading frames (ORFs) encoding conserved domains, with typical features of badnaviruses. Additionally, BLASTn searches indicated the CoVCV genome sequence is most similar to the grapevine vein clearing virus (GVCV) genome (72% identity and 46% query coverage)...

Botryosphaeria dothidea is an important pathogenic fungus that causes serious diseases in fruits and trunks of many wood plant species worldwide. In this study, 28 B. dothidea strains isolated from pear trunk samples showing stem wart or canker symptoms were used to detect double-stranded RNA (dsRNA) viruses. The dsRNA bands with the size of ~ 1.0 to ~ 6.0 kbp were examined from ten strains. Here, we reported a novel dsRNA mycovirus, tentatively named as Botryosphaeria dothidea victorivirus 2 (BdVV2), isolated from the B...

Control of classical swine fever (CSF) in developing countries is achieved by immunization with attenuated vaccines, such as the lapinized C-strain vaccine that has been widely used in China. However, C-strain has relatively low growth rate in cell cultures, thus affecting productivity of the vaccine for the industry. In this study, eight amino acid residues were mutated on the C-strain backbone, resulting in a cell-adapted strain Cmut8. The mutant strain exhibited rapid growth with titer of about 100 fold higher than its parental C-strain...

Forty-five papaya samples showing severe leaf curl symptoms were tested by PCR with a degenerate primer set for virus species in the genus Begomovirus. Of these, 29 were positive for tomato leaf curl Bangladesh virus (ToLCBV). The complete genome sequences of ToLCBV (GenBank accession no. MH380003) and its associated tomato leaf curl betasatellite (ToLCB) (MH397223) from papaya isolate Gaz17-Pap were determined and characterized. Defective betasatellites were found in ToLCBV-positive papaya isolates Gaz19-Pap, Gaz20-Pap and Gaz21-Pap...

Lumpy skin disease (LSD) has affected many regions of Russia since its first occurrence in 2015. The most devastating year for Russia was 2016, when the virus resurged following a modified stamping-out campaign, causing 313 outbreaks in 16 regions. To avoid unwanted adverse reactions following the use of live attenuated vaccines against LSD virus (LSDV), sheeppox-based vaccines were administered during vaccination campaigns. As a result, LSD was successfully contained in all Russian regions in 2017. In the same year, however, LSD emerged anew in a few regions of the Privolzhsky Federal District of Russia along the northern border of Kazakhstan, which then necessitated vaccinating cattle with a live attenuated LSDV vaccine...

Hazara virus (HAZV) is closely related to Crimean-Congo hemorrhagic fever virus (CCHFV), but differs in that it is non-pathogenic to humans. Since HAZV was isolated for the first time in 1954, the biological characteristics of this virus, particularly its behavior within culture cells, have not been well-studied, despite its importance as a surrogate model for CCHFV. Nucleoprotein (N) is the main component of viral nucleocapsid and is the most abundant virion protein, it is believed to play a pivotal role in the viral lifecycle...
