“…In this study we evaluated the effect of IFN-α-n3 on the pH1N1 and other 2 Influenza A viruses including Avian H9N2 HK97 and Swine H3N2 TX98 viruses. Both Avian H9N2 and Swine H3N2 viruses have been documented to infect humans [6,7]. Our results demonstrated that 100 IU of IFN-α-n3, a natural leukocyte interferon alpha product, can efficiently inhibit replication of 2009 pH1N1 and Avian H9N2 viruses in human A549 cells; however, 16 hours of incubation is needed.…”

“…The H9N2 Avian Influenza virus has been considered to be another candidate causing the next pandemic because infections with this subtype of virus in humans have been reported [5,6] and normally humans do not have immunity against this subtype of virus. Recently, more than 10 human cases infected with triple reassortant H3N2 Swine Influenza virus containing the M gene from the pH1N1 virus were reported in the USA [7]. The common feature is that these viruses do not have the ability of human-to-human transmission.…”

“…Embora os genes do vírus A(H1N1)pdm09 serem provenientes de linhagens de vírus da influenza suína da América do Norte e Eurásia (Garten et al 2009), não há evidências que esse vírus estivesse circulando em suínos antes de ocorrer a pandemia em humanos (Yoon 2012). A grande preocupação é que os suínos são considerados a espécie onde o vírus influenza sofre rearranjos ou trocas de genes virais com maior facilidade, originando novos vírus influenza, como tem sido observado recentemente (Ducatez et al 2011, Moreno et al 2011, Liu et al 2012. A grande diversidade genética encontrada nos vírus influenza em diferentes regiões geográficas, aliado ao fato da influenza ser uma zoonose, torna muito importante a obtenção de dados genéticos dos vírus isolados de suínos para monitorar possíveis mutações e rearranjos gênicos.…”

“…O conhecimento dos principais vírus influenza circulantes no Brasil ainda é escasso, pois não há um sistema de monitoria oficial para essa doença. Dessa forma, uma alternativa para o controle de influenza em rebanhos brasileiros seria a utilização de vacinas autógenas, tendência também observada atualmente nos Estados Unidos, devido ao surgimento de novos vírus como o A(H1N1)pdm09 e vírus endêmicos de suínos (Liu et al 2012). Estas vacinas são preparadas a partir de amostra do vírus influenza isolada de um animal ou de uma população, e aplicadas na mesma população.…”

“…Determining if there has been exchange of the internal genes during reassortment depends on identifying the close homologues of the internal genes from the viral subtype under consideration (4). This is usually carried out by using a database search tool such as BLAST (5)(6)(7). Such analyses are time consuming and it is difficult to set an appropriate threshold for homology and commonly a cut-off of above 90% comparative identity might be used.…”
