| surveillance of avian influenza viruses in northern pintails (anas acuta) in tohoku district, japan. | among winter migratory waterfowl, northern pintails (anas acuta), in one of the largest flocks in tohoku district, northeast japan, were surveyed for influenza a viruses at five wintering sites in three prefectures, viz., aomori, akita, and miyagi. a total of 38 influenza a viruses were isolated from 2066 fecal samples collected during november 2006 through march 2007. the overall isolation rate was 1.84%. eleven different subtypes were isolated, including nine h5n2, seven h6n8, seven h10n1, fou ... | 2008 | 18459295 |
| inactivation of avian influenza virus h1n1 by photocatalyst under visible light irradiation. | a novel photocatalyst - ilumio (platinum-loaded tungsten oxide) - was evaluated for its anti-influenza virus activity with the avian isolate a/northern pintail/miyagi/1472/08 (h1n1). under a fluorescent lamp of 1000lx in the absence of ultraviolet light, the virus was inactivated to below the detection limit i.e. >5.3log inactivation within 2h. this photocatalyst can be used for coating walls, tables, and other surfaces to decrease virus infectivity associated with surfaces. this would be desira ... | 2010 | 20302898 |
| genetic analysis of avian influenza viruses: cocirculation of avian influenza viruses with allele a and b nonstructural gene in northern pintail (anas acuta) ducks wintering in japan. | the pandemic influenza virus strains of 1918 (h1n1), 1957 (h2n2), 1968 (h3n2), and 2009 (h1n1) have genes related to avian influenza viruses (aivs). the nonstructural (ns) gene of aivs plays a significant role in host-viral interaction. however, little is known about the degree of diversity of this gene in northern pintail (anas acuta) ducks wintering in japan. this study describes characteristics of pintail-originated h1n1, h1n2, h1n3, h5n2, h5n3, h5n9, and h7n7 viruses. most of the viruses wer ... | 2012 | 23320157 |
