| [characteristics of epidemiological strains of influenza a virus (h3n2) isolate in 1997-1999. virus a/moscow/10/99--a candidate to become the vaccine strain]. | antigenic properties of influenza a(h3n2) viruses isolated during two epidemic seasons 1997-98 and 1998-99 in russia are analyzed. all strains are antigenic variants of the reference strain a/sydney/5/97. characteristics of epidemic strain a/moscow/10/99, proposed by who expert committee as vaccine strain for 1999-2000 have been studied. this strain, isolated on chick embryos, is characterized by high reproductive activity in chicken embryos with an infectious titer of 10(6) eid50/0.2 ml, easily ... | 2000 | 10971961 |
| [epidemic strains influenza viruses a and b in the 2005-2006 season in russia]. | investigations indicated that the epidemic upsurge of influenza morbidity in the 2005-2006 season in russia was caused by the active circulation of influenza viruses a and b. the center for ecology and epidemiology of influenza, d. i. ivanovsky institute of virology, russian academy of medical sciences, studied 182 epidemic strains. a hundred and thirteen influenza viruses a(h3n2) were similar to the reference a/california/07/2004 or were its antigenic variants. thirteen influenza virus a(h1n1) ... | 2008 | 18756810 |
| [interpretation of the epizootic outbreak among wild and domestic birds in the south of the european part of russia in december 2007]. | the paper presents the results of interpreting the epizootic outbreak etiologically associated with high-virulent influenza virus a/h5n1 among domestic and wild birds in the zernogradsky and tselinsky districts of the rostov region. epizooty was characterized by a high infection rate in the synanthropic birds of a ground-based complex. rt-pct revealed influenza virus a/h5 in 60% of pigeons and crows and in around 20% of starlings, and in 10% of tree sparrows. fifteen viral strains from chickens ... | 2008 | 18756811 |
| [the characteristics of epidemic influenza a and b virus strains circulating in russia during the 2007-2008 season]. | in 2007-2008 in russia, the epidemic upsurge of influenza morbidity was caused by the active circulation of influenza a(h1n1, a(h3n2), and b viruses. the center for ecology and epidemiology of influenza studied 334 epidemic strains. the results of a comparative study of the svirus specificity of commercial test systems (amplisens influenza virus a/b and amplisens influenza virus a/h5n1) for the polymerase chain reaction diagnosis and virological assays, including virus isolation, revealed their ... | 2009 | 19882900 |
