35、sis for killing wildbirds to protect poultry and minimize the risk of human infection.The European team investigating the global spread of the H5N1 strain of avian influenza(禽流感)says certain duck species may be infecting wild bird populations.Geese and wading birdsare also possible vectors(带菌者)of th

36、e virus,the team says.The teams study was led by Bjorn Olsen of Umea University in Sweden.Olsen runs Europeslargest wild-bird flu monitoring program.Studies have shown that influenza viruses in lake water,generally passed via bird ffeces(粪),can stay infectious for up to 30 days.The migration or feed

37、ing behavior of dabbling ducks could atleast partially explain the spread of the H5N1 strain of bird flu,the researchers add.This group of duck species includes mallards,teal,pintails,and others that feed at or near thesurface,where viruses in water are most likely to be picked up.Perhaps as a resul

38、t,dabblers havethe highest known rates of avian influenza infection,the study says.For instance,nearly 13percent of mallards tested positive for bird flu.Other species tested include the American blackduck(18.1 percent),blue-winged teal(11.5 percent),and northern pintail(11.2 percent).However,bird f

39、lu viruses appear to exist in ducks in a low-pathogenic form,meaninginfection doesnt usually lead to severe illness and death.Dabbling ducks are for sure the prime hosts for low pathogenic viruses,said studyco-author Ron Fouchier,a virologist at the Erasmus Medical Center in Rotterdam,Netherlands.Bu

40、i the big question is,how much of our knowledge about these viruses can we translate tohigh-pathogenic viruses such as the H5N1 strain of bird flu?In poultry avian viruses can mutate(变异)into more virulent influenza strains,includingH5N1.If this mutated virus then finds its way back into wild populat

41、ions,the birds could thenspread the disease through migration.Some scientists have argued that wild birds infected with HN51 would be too ill to migrate.Swans,for instance,appear to be particularly vulnerable to the strain.Swans apparently dropdead quite easily,but they are unlikely to be the vector

42、 because they are not going to fly very far ifthey are dead,Fouchier said.But the study team says that some birds that have been purposely infected for the sake ofresearch show that wild birds can survive H5N1.For some reason H5N1 has adapted so it nolonger kills dabbling ducks,1 Fouchier said.This

43、means the ducks may be able to spread the virusover a wide area.The study team says migratory geese may also be vectors,because they often graze in hugeflocks,a practice that could encourage transmission.Migrating ducks,the researchers add,could provide an intercontinental bridge for bird fluto Nort

47、ded by one or another series of scientific experiments.Three hundred years seems along time for testing a new approach to human inter-living,long enough to set back for criticalappraisal of the scientific method,maybe even long enough to vote on whether to go on with it ornot.There is an argument.Vo
