Abstract:
Birds,especially wild waterfowls,are a natural reservoir of influenza virus,though poultry,mammalians and even human beings are also thought to be the potential hosts.Influenza virus can be classified into subtypes according to the characteristics of the nucleocapsid protein and membrane protein,each subtype with its own most adaptable host,so called host range restriction.However,the outbreak and spreading of influenza in different species has aroused increasing attention since its disastrous consequence on the ecological system of the earth.Large-scale epidemic survey,prediction of possible mutation of the virus,development and application of vaccines are key actions to be taken to prevent the pandemic of influenza.This article offers an overview of the ecology of influenza virus,features of recent great outbreaks of avian influenza,and relevant issues of concern.
