The H7N7 subtype of avian influenza in addition has developed highly pathogenic variants and offers demonstrated the capability to infect many species, including birds, humans and pigs. H9N2 influenza strains have got only been documented in low pathogenic type, but several situations of human illness have been verified. As the H5, H7 and H9 subtypes usually do not currently circulate in humans, there is no pre-existing immunity to these strains in the general population no prophylactic vaccines are currently available. The ability of these strains to cross the species barrier increases their pandemic potential greatly. ATCC offers patents pending for the isolated avian flu antibodies aswell as for methods of using the antibodies to diagnose infections with avian influenza virus..For the scholarly study, published Aug. 20 online in the journal Stroke, Persson and co-workers collected data on 248 stroke survivors under 70 years previous and their spouses. The researchers compared them with 245 wives and husbands of people who didn’t have a stroke. All the strokes were the effect of a blocked artery to the brain. At the seven-year follow-up, spouses of stroke survivors had more health problems of their own, including pain, than those whose partners hadn’t had a stroke. They also scored lower than the additional spouses on all procedures of physical and mental functioning.
