Assessment of resistance to rice tungro disease in popular rice varieties in India by introgression of a transgene against Rice tungro bacilliform virus.

Arch Virol 2019 Feb 8. Epub 2019 Feb 8.

Department of Plant Molecular Biology, University of Delhi South Campus, New Delhi, 110021, India.

Rice crops in South and Southeast Asian countries suffer critical yield losses due to rice tungro disease caused by joint infection with rice tungro bacilliform virus (RTBV) and rice tungro spherical virus (RTSV). Previously, for generating RNA interference-based transgenic resistance against tungro viruses, RTBV ORF IV was used as a transgene to develop RTBV resistance in a popular high-yielding scented rice variety. The transgene from this line was then introgressed into five popular high-yielding but tungro-susceptible rice varieties by marker-assisted backcross breeding with a view to combine the resistant trait with the agronomic traits.

An amino acid duplication/insertion in the Bm126 gene of Bombyx mori nucleopolyhedrovirus alters viral gene expression as shown by differential gene expression analysis.

Arch Virol 2019 Jan 24. Epub 2019 Jan 24.

Jiangsu Key Laboratory of Sericultural Biology and Biotechnology, School of Biotechnology, Jiangsu University of Science and Technology, Zhenjiang, 212018, Jiangsu, People's Republic of China.

Open reading frame (ORF) 126 (Bm126) of Bombyx mori nucleopolyhedrovirus (BmNPV) is not essential for viral replication, and two subtypes of this gene have been identified in China. The Bm126-SX subtype encodes a protein with a simple amino acid duplication/insertion relative to the Bm126-GD subtype; however, significant differences in the cytopathic effect and infectivity of viruses carrying these variant genes have been observed. To elucidate the cause of these differences, differential gene expression analysis was performed at the early stage of infection with viruses harbouring variants of Bm126. Read More

Intratype variants of the E2 protein from human papillomavirus type 18 induce different gene expression profiles associated with apoptosis and cell proliferation.

Arch Virol 2019 Jan 10. Epub 2019 Jan 10.

Unidad de Investigación Biomédica en Cáncer, Instituto Nacional de Cancerología, México/Instituto de Investigaciones Biomédicas, Universidad Nacional Autónoma de México, Av. San Fernando No. 22, Col. Sección XVI, Tlalpan, 14080, Mexico City, CDMX, Mexico.

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. Read More

Interaction of historical and modern Sardinian African swine fever viruses with porcine and wild-boar monocytes and monocyte-derived macrophages.

Arch Virol 2019 Jan 10. Epub 2019 Jan 10.

Istituto Zooprofilattico Sperimentale della Sardegna, Via Vienna 2, 07100, Sassari, Italy.

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. Read More

Arch Virol 2019 Jan 5. Epub 2019 Jan 5.

Molecular Pathology Laboratory, Institute of Molecular Biosciences, Mahidol University, Salaya Campus, 25/25 Phuttamonton Sai 4, Salaya, Nakorn Pathom, 73170, Thailand.

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. Read More

Analysis of natural recombination and host-related evolutionary dynamics of avian avulavirus 1 isolates based on positive and negative selection from 1948 to 2017.

Arch Virol 2019 Jan 5. Epub 2019 Jan 5.

Central Laboratory Department, Razi Vaccine and Serum Research Institute, Agricultural Research, Education and Extension Organization (AREEO), Karaj, Alborz, Iran.

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. Read More

Diagnostic Laboratory, School of Veterinary Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, 11 Stavrou Voutyra Str., 54627, Thessaloniki, Greece.

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. Read More

Arch Virol 2019 Jan 1. Epub 2019 Jan 1.

Medical College, Jiangsu University, 301 Xuefu road, Zhenjiang, 212013, People's Republic of China.

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.

Prevalence of HIV-1 transmitted drug resistance and viral suppression among recently diagnosed adults in São Paulo, Brazil.

Arch Virol 2018 Dec 20. Epub 2018 Dec 20.

Núcleo de Doenças Sanguíneas e Sexuais-Laboratório de Retrovírus, Centro de Virologia, Instituto Adolfo Lutz, Av Dr. Arnaldo, 355, São Paulo, SP, 01246-902, Brazil.

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. Read More
