Persistent infections with high-risk human papillomaviruses (HR-HPVs) are linked to development of cervical cancer due to a deregulation of the productive viral cycle in the host cell, leading to cell transformation. The E2 viral protein is expressed early during an HPV infection and regulates viral replication and transcription. Other functions have been attributed to E2, such as the promotion of apoptosis that are independent of its role in the regulation of the expression of E6 and E7 viral oncogenes. Moreover, it has been shown that the HPV16 E2 protein has regulatory effects on cellular gene expression, suggesting that it participates in the modulation of different cellular processes...

African swine fever (ASF) is a contagious viral disease of wild and domestic pigs that is present in many parts of Africa, Asia and Europe, including Sardinia (Italy). Deletions in the EP402R and B602L genes have been found in almost all ASF virus (ASFV) strains circulating in Sardinia from 1990 onwards, and modern Sardinian strains (isolated after 1990) might have acquired some selective advantage compared to historical ones (isolated before 1990). Here, we analysed the host cell responses of wild boars and domestic pigs upon infection with virus variants...

A variety of viruses can cause acute flaccid paralysis (AFP). However, the causative agent, sometimes, remains undetermined. Metagenomics helps in identifying viruses not diagnosed by conventional methods. Stool samples from AFP (n = 104) and non-AFP (n = 114) cases that tested enterovirus-negative by WHO standard methods were investigated. A metagenomics approach, first used on five pools of four samples each, revealed the presence of adenovirus sequences. Amplification in A549 cells and full-genome sequencing were used for complete virus identification and for designing a PCR assay to screen individual related samples...

Zika virus (ZIKV) has been endemic in Southeast Asian countries for several years, but the presence of the virus has not been associated with significant outbreaks of infection unlike other countries around the world where the Asian lineage ZIKV was introduced recently. However, few studies have been undertaken using the endemic virus. The Thai isolate was shown to have a similar tissue tropism to an African isolate of ZIKV, albeit that the Thai isolate infected cells at a lower level as compared to the African isolate...

Adaptation and evolution of avian avulavirus 1, or Newcastle disease virus (NDV), has led to tremendous economic losses worldwide. The occurrence of natural recombination and selection pressure has been traced for NDV based on a few recent reports, but a dominant pattern based on genomic characteristics is lacking. Here, we used bioinformatics tools to search for evidence of recombination in all of the available complete genome sequence of NDV (462 sequences) using RDP4 software. Geographical linkage and host cell relationships of recombinant viruses were also investigated, and a study of the adaptive evolution of avian avulavirus 1 was performed...

Enzootic nasal adenocarcinoma (ENA) is a contagious neoplasm of sheep and goats, associated with the oncogenic retroviruses enzootic nasal tumor virus (ENTV) 1 and 2, respectively. It appears to be common in countries with substantial small ruminant-production. ENA diagnosis in goats is based on autopsy and histopathology, and there is no real-time PCR method available for ENTV-2 detection. Here, a novel one-tube real-time RT-PCR (RT-qPCR) method for the detection and quantification of ENTV-2 in nasal swabs is presented...

Coxsakievirus (CV) B4, CVB5, and CVA9 belong to the species Enterovirus B. These viruses can cause viral encephalitis, aseptic meningitis, pancreatitis, flaccid paralysis, dilated myocarditis, and hand, foot, and mouth disease (HFMD). In order to analyze the evolution of CVB4, CVB5, and CVA9, we analyzed all of the available genome sequences of Enterovirus B (EVB) isolates and found that there were 12 putative recombination events that produced CVB4, 13 putative recombination events that produced CVB5, and 10 putative recombination events that produced CVA9...

The complete genome of a novel mycovirus, Puccinia striiformis mitovirus 1 (PsMV1), derived from the wheat stripe rust fungus Puccinia striiformis strain SCSN-10, was sequenced and analyzed. The full-length cDNA sequence is 2496 bp in length with a predicted AU content of 57.65% in the genomic RNA. Sequence analysis indicated that a single large open reading frame (ORF) is present on the positive strand when the fungal mitochondrial genetic code is used. The single ORF encodes a putative RNA-dependent RNA polymerase of 743 amino acids with a molecular mass of 84...

HIV-1 transmitted drug resistance (TDR) mutations may reduce the efficacy of antiretroviral therapy (ART), but pre-treatment testing to determine the virus genotype can improve the efficacy of ART. Unfortunately, issues related to cost and logistics of pre-treatment testing limit its use in resource-limited settings. We studied 596 ART-naive individuals who were newly diagnosed from 2014 to 2016 in São Paulo, Brazil, to evaluate TDR and virological outcome after 48 weeks of genotype-guided therapy. One or more TDR (based on the WHO surveillance list) was observed in 10...

Recently, infectious disease outbreaks characterized by swelling and hemorrhagic liver and kidneys occurred in Muscovy ducklings in China. Four viruses were isolated and identified as adenoviruses by transmission electron microscopy (TEM) and polymerase chain reaction (PCR). Sequence analysis identified the new isolates as duck adenovirus 3 (DAdV-3), species Duck aviadenovirus B. The pathogenicity of the new isolate DAdV-3 FJGT01 was investigated using challenge experiments. The gross lesions in the animal experiment were similar to the clinical lesions observed in the diseased ducks...

Members of the bacterial genus Aeromonas are important aquatic pathogens that cause severe fish diseases. Here, we characterize a novel lytic phage, Aeromonas virus phiA8-29, isolated from the alimentary tract of a freshwater fish. Transmission electron microscopy showed that phiA8-29 has a long contractile tail and thus can be classified as a member of the family Myoviridae. The phage genome was identified as a double-stranded DNA molecule of 144,974 bp containing 185 open reading frames and nine tRNA-encoding genes...

Human infection by low-pathogenic avian influenza viruses of the H7N9 subtype was first reported in March 2013 in China. Subsequently, these viruses caused five outbreaks through September 2017. In the fifth outbreak, H7N9 virus possessing a multiple basic amino acid insertion in the cleavage site of hemagglutinin emerged and caused 4% of all human infections in that period. To date, H7N9 highly pathogenic avian influenza viruses (HPAIVs) have been isolated from poultry, mostly chickens, as well as the environment...

In 2009, a new viral disease of citrus caused by citrus yellow vein clearing virus (CYVCV) was first discovered in China. CYVCV is considered to be the most serious pathogen affecting lemon production. In this study, a sensitive and reliable reverse transcription droplet digital polymerase chain reaction (RT-ddPCR) assay was developed to detect and quantify CYVCV without references. The specificity of the assay was demonstrated by its failure to amplify other relevant citrus viruses. The quantitative linearity, sensitivity and accuracy of RT-ddPCR for detecting CYVCV were compared to those of real-time RT-PCR...

Viruses are ubiquitous in the biosphere and greatly affect the hosts they infect. It is generally accepted that members of every microbial taxon are susceptible to at least one virus, and a plethora of bacterial viruses are known. In contrast, knowledge of the archaeal virosphere is still limited. Here, a novel lytic archaeal virus is described, designated "Drs3", as well as its host, Methanobacterium formicicum strain Khl10. This hydrogenotrophic methanogenic archaeon and its virus were isolated from the anaerobic digester of an experimental biogas plant in Germany...
