Infection with reticuloendotheliosis virus (REV), a gammaretrovirus in the family Retroviridae, can result in immunosuppression and subsequent increased susceptibility to secondary infections. In the present study, we identified differentially expressed proteins in the spleens of chickens infected with the REV-A HLJ07I strain, using two-dimensional gel electrophoresis on samples from time points coinciding with different phases of the REV life cycle. Differentially expressed proteins were identified using one-dimensional liquid chromatography electrospray ionization tandem mass spectrometry (1D LC ESI MS/MS)...

Puumala virus (PUUV) represents one of the most important hantaviruses in Central Europe. Phylogenetic analyses of PUUV strains indicate a strong genetic structuring of this hantavirus. Recently, PUUV sequences were identified in the natural reservoir, the bank vole (Myodes glareolus), collected in the northern part of Poland. The objective of this study was to evaluate the presence of PUUV in bank voles from southern Poland. A total of 72 bank voles were trapped in 2009 at six sites in this part of Poland...

Four isolates of a bipartite begomovirus from naturally infected Deinbollia borbonica plants exhibiting yellow mosaic symptoms in Kenya and Tanzania were molecularly characterised. The DNA-A was most closely related to that of tomato leaf curl Mayotte virus (AM701764; 82%), while the DNA-B shared the highest nucleotide sequence identity with that of East African cassava mosaic virus (AJ704953) at 65%. Based on the current ICTV species demarcation criterion for the genus Begomovirus (≥91% sequence identity for the complete DNA-A), we report the full-length genome sequence of this novel bipartite begomovirus...

Bubaline alphaherpesvirus 1 (BuHV1) is a member of the family Herpesviridae, subfamily Alphaherpesvirinae, genus Varicellovirus. To date, no full genome sequence of BuHV has been published. Here, we report the complete genome sequence of bubaline alphaherpesvirus 1 (BuHV1) strain b6 (BuHV1-b6), isolated from a water buffalo (Bubalus bubalis) in 1972 in Australia. The virus was multiplied in MDBK cells, and the DNA was extracted and subjected to high-throughput sequencing. The reads were aligned and combined into a single genome sequence, with bovine alphaherpesvirus 5 (BoHV5) strain SV507/99 (accession number NC005261) as a reference...

Bamboo mosaic virus (BaMV) is a well-characterized virus and a model of virus-host interaction in plants. Here, we identified naturally occurring BaMV isolates from Fujian Province, China and furthermore describe a naturally occurring BaMV coinfection in bamboo (Bambusa xiashanensis) plants. Two different types of BaMV were identified, represented by isolates BaMV-XSNZHA7 (X7) and BaMV-XSNZHA10 (X10). The phylogenetic relationships between X7- and X10-like isolates and published BaMV isolates were determined based on genomic RNA and amino acid sequences...

Molecular characterization of the most common dsRNA element from Trichoderma atroviride indicated that it comprised 8,566 bp and encoded two large open reading frames (ORF1 and 2). The two ORFs were found to overlap by 46 bp with a typical (-1) slippery heptanucelotide sequence. The deduced protein sequences of ORF1 and ORF2 showed significant similarities to those of known mycoviral structural proteins and RNA-dependent RNA polymerases, respectively. Phylogenetic analysis indicated that this dsRNA is a member of a distinct species related to a group of unclassified mycoviruses; therefore, it was named Trichoderma atroviride mycovirus 1 (TaMV1)...

The complete nucleotide sequence of fig fleck-associated virus from Xinjiang Uygur Autonomous Region of China (FFkaV-CN) was determined. The 6,723-nucleotide-long viral genome, excluding a terminal poly(A) tail, contains three open reading frames (ORFs). Pairwise comparisons showed that FFkaV-CN shares 83% and 92% sequence identity with FFkaV-Italy based on the complete genomic sequence and CP aa sequence, respectively, slightly higher than the species demarcation criterion for the genus Maculavirus. Phylogenetic analysis showed that FFkaV-CN and FFkaV-Italy clustered into one group...

Mast cells reside in many tissues, including the lungs, and might play a role in enhancing influenza virus infections in animals. In this study, we cultured porcine mast cells from porcine bone marrow cells with IL-3 and stem cell factor to study the infectivity and activation of the 2009 pandemic H1N1 influenza virus of swine origin. Porcine mast cells were infected with H1N1 influenza virus, without the subsequent production of infectious viruses but were activated, as indicated by the release of histamines...

Nucleotide sequences are the fundamental basis for work on molecular mechanisms and for phylogenetic analysis. Recently, we identified sequence errors in all of the LTR sequences of the prototypic foamy virus stored in the GenBank database. Here, we report the resequencing of the proviral plasmids pHSRV13 and pHSRV2. Sequence comparisons revealed an error rate for the foamy virus sequences stored in the database of up to 10 errors per 1000 bp. Even the newest sequences of the codon-optimized foamy virus synthetic Gag, Pol, and Env amino acid sequences showed exchanges compared to the new proviral pHSRV13n sequence...

Reactive species are frequently formed after viral infections. Antioxidant defences, including enzymatic and non-enzymatic components, protect against reactive species, but sometimes these defences are not completely adequate. An imbalance in the production of reactive species and the body's inability to detoxify these reactive species is referred to as oxidative stress. The aim of this review is to analyse the role of oxidative stress in the pathogenesis of viral infections and highlight some major therapeutic approaches that have gained importance, with regards to controlling virus-induced oxidative injury...

Despite the prevalence of Newcastle disease virus (NDV) outbreaks in India through the decades, there has been little genetic characterisation of the virulent strains circulating in Northeast India. In 2014, a poultry farm in the Kamrup district of Assam reported an ND outbreak. In this study, genetic analysis and clinicopathological tests showed the virulent nature of the isolate Kamrup. Based on prudent classification criteria, the virulent strain Kamrup was found to be most closely related to members of genotype XIII of class II NDV...

Picobirnavirus (PBV) is a small, bi-segmented, double-stranded RNA virus. Taxonomically, the genus Picobirnavirus belongs to the Picobirnaviridae family. PBV infects a wide range of hosts and causes opportunistic infections, but its role in diarrheal disease remains unclear. To determine the prevalence and genetic diversity of porcine PBVs in Northern Thailand, 380 fecal samples collected from diarrheic and non-diarrheic piglets, raised in 22 pig farms, were tested for the presence of PBV. Reverse-transcription PCR (RT-PCR) was performed using primer sets specific to the RNA-dependent RNA polymerase (RdRp) gene...

Klebsiella is a genus of well-known opportunistic human pathogens that are associated with diabetes mellitus and chronic pulmonary obstruction; however, this pathogen is often resistant to multiple drugs. To control this pathogen, two Klebsiella-infecting phages, K. oxytoca phage PKO111 and K. pneumoniae phage PKP126, were isolated from a sewage sample. Analysis of their host range revealed that they infect K. pneumoniae and K. oxytoca, suggesting host specificity for members of the genus Klebsiella. Stability tests confirmed that the phages are stable under various temperature (4 to 60 °C) and pH (3 to 11) conditions...

In March 2016, a cluster of unexplained respiratory illnesses was reported by the acute respiratory infections (ARI) surveillance system of Guangdong Province, China. Twenty-three high school students and one teacher from the four neighboring classes were admitted to a hospital. CVA21 was found in eight of fourteen patients. Phylogenetic analysis suggested that the CVA21 outbreak was most likely caused by transmission of the virus from person to person. This is the first report of an ARI outbreak caused by CVA21, which suggests that CVA21 has the potential to be transmitted efficiently from person to person and should be closely monitored by clinicians and public health agencies...

MicroRNAs (miRNAs) are a class of endogenous small non-coding RNAs (sRNA) that play an essential role in the regulation of target mRNAs expressed during plant development and in response to stress. MicroRNA expression profiling has helped to identify miRNAs that regulate a range of processes, including the plant's defence response to pathogens. In this study, differential miRNA expression in own-rooted Vitis vinifera cv. Cabernet Sauvignon plants infected with grapevine leafroll-associated virus 3 was investigated with microarrays and next-generation sequencing (NGS) of sRNA and mRNA...

Bovine leukemia virus (BLV) causes enzootic bovine leucosis (EBL) and is responsible for substantial economic losses in cattle globally. However, information in Africa on the disease is limited. Here, based on clinical, hematological, pathological and molecular analyses, two clinical cases of EBL were confirmed in a dairy cattle herd in Zambia. In contrast, proviral DNA was detected by PCR in five apparently healthy cows from the same herd, suggesting subclinical BLV infection. Phylogenetic analysis of the env gene showed that the identified BLV clustered with Eurasian genotype 4 strains...
