RNA-based vaccination of Bhut Jolokia pepper (Capsicum chinense Jacq.) against cucumber mosaic virusVirusDisease - Tập 29 - Trang 207-211 - 2018
Munmi Borah, Margarita Berbati, Chrysavgi Reppa, Maria Holeva, Palash Deb Nath, Andreas Voloudakis
Cucumber mosaic virus (CMV) causes great losses in Bhut Jolokia pepper (Capsicum chinense Jacq.) plantations in Assam, India. To investigate possible means to induce plant resistance against this virus, the crude extract of bacterially-expressed double-stranded (ds) RNA, derived from CMV-2b gene (dsRNA_CMV-2b), was exogenously applied along with CMV-G strain onto Bhut Jolokia plants. In this ‘RNA-...... hiện toàn bộ

Brazilian traditional medicine has explored the antiviral properties of many plant extracts, including those from the Brazilian pepper tree, Schinus terebinthifolius. In the present study, we investigated the chemical composition and anti-mayaro virus (MAYV) activity of S. terebinthifolius fruit. Extensive virucidal activity (more than 95%) was detected for the ethyl acetate extract and the isolat...... hiện toàn bộ
Animal PicobirnavirusVirusDisease - Tập 25 - Trang 223-238 - 2014
Balasubramanian Ganesh, Gisela Masachessi, Zornitsa Mladenova
Picobirnavirus (PBV) is a small, non-enveloped, bisegmented double-stranded RNA (dsRNA) virus of vertebrate hosts. The name ‘Picobirnavirus’ derives from the prefix ‘pico’ (latin for ‘small’) in reference to the small virion size, plus the prefix ‘bi’ (latin for ‘two’) and the word ‘RNA’ to indicate the nature of the viral genome. The serendipitous discovery of PBV dates b...... hiện toàn bộ
Characterization of evolutionary changes in hemagglutinin of influenza H1N1 virus: a computational analysisVirusDisease - Tập 27 - Trang 34-40 - 2016
Zaira Rehman, Rehan Zafar, Uzma Amir, Umer H. K. Niazi, Ammad Fahim
Influenza virus continues to evolve due to changes in the genome and the new strain of virus is more pathogenic then the previous strain. These changes may also help the virus to cross specie barrier and may also affect the binding pattern of virus.The main theme of the current study is the identification of changes in the hemagglutinin sequence of H1N1 virus from 1960 to 2011 and also how these c...... hiện toàn bộ
A cross sectional study of the risk factors of hepatitis C infection in North EgyptVirusDisease - Tập 32 - Trang 22-28 - 2021

Hepatitis C is a viral infection that has been declared as a global health problem by the World Health Organization. Egypt has the highest prevalence of hepatitis C virus (HCV) which results in a high morbidity and mortality from chronic liver disease, cirrhosis, and even hepatocellular carcinoma. Cities have lower rates of infection than rural areas. Studies about the abnormally high prevalence o...... hiện toàn bộ
First report of cucumber mosaic virus infecting antamul vine (Tylophora indica) in IndiaVirusDisease - Tập 30 - Trang 319-320 - 2018
Ram Prasnna Meena, P. Manivel
Tylophora indica (Burm f.) Merrill; commonly known as antamul, is an important medicinal herb. Typical yellow rings or irregular yellow spot and in severe condition necrotic rings were observed on the leaves of the crop. The examination of symptomatic leaf samples under transmission electron microscopy revealed the presence of spherical virions confirmed the association of cucumo like virus group....... hiện toàn bộ
First report of association of potato virus X and potato virus Y and ‘Candidatus Phytoplasma trifolii’ in brinjal in IndiaVirusDisease - Tập 27 - Trang 207-208 - 2016
Manish Kumar, Akshay Katiyar, Madhupriya, G. P. Rao
Symptoms of little leaf, leaf chlorosis and leaf malformations with mosaic mottling symptoms were observed in two brinjal varieties (Pusa Shyamla and Pusa Purple Cluster) in fields of IARI, New Delhi, India during 2014–2015. Electron microscopy, PCR and sequence analysis first time provided evidence of association of Candidatus Phytoplasma trifolii with potato virus X and potato virus Y in brinjal...... hiện toàn bộ
