TL;DR: The geographic expansion of the infection and its persistence for several years indicate efficient transmission of canine influenza virus among greyhounds, and evidence of infection in pet dogs suggests that this infection may also become enzootic in this population.

TL;DR: It is found that persons who work with swine are at increased risk of zoonotic swine influenza virus infection, and it is prudent to include them in pandemic planning efforts.

TL;DR: These studies indicate that influenza A and B viruses induce apoptosis in cell cultures; thus, apoptosis may represent a general mechanism of cell death in hosts infected with influenza viruses.

TL;DR: Since 1997, novel viruses of three different subtypes and five different genotypes have emerged as agents of influenza among pigs in North America, and research on these novel viruses may offer important clues to the genetic basis for interspecies transmission of influenza viruses.

TL;DR: The full-length protein coding regions of all eight RNA segments from four H3N2 viruses isolated from pigs in the Midwestern U.S. are sequenced, showing that these viruses are reassortant viruses containing hemagglutinin, neuraminidase and PB1 polymerase genes from human influenza viruses, matrix, non-structural and nucleoprotein genes from classical swine viruses, and PA and PB2 polymerases genes from avian viruses.
