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

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 better understanding of the aetiology of acute gastroenteritis (AGE) outbreaks in Southeast Nigeria would help safeguarding public health. This study screened stool samples collected from infants (children < 5 years of age) attending selected hospitals in Nsukka for human enteric viruses and evaluated the seasonality of AGE based on three-year records available at selected hospitals. A total of ...... hiện toàn bộ
Molecular characterization and field survey of Iranian potato virus X isolatesVirusDisease - Tập 25 - Trang 338-344 - 2014

Six hundred and one symptomatic potato samples were collected from nine provinces in Iran. Screening by double-antibody sandwich enzyme linked immunosorbent assay using a potato virus X (PVX) together with a few potyviruses polyclonal antibodies, produced positive reactions in 4.3 % of samples against PVX. Based on symptoms on different test plant, the isolates were divided into two groups: the fi...... hiện toàn bộ
