 [导语]对于很多旅游爱好者来说，南极游可能是一生一次的梦想；但是对于南极“土著”鸟类来说，游客的到来却可能是对它们生命的威胁。英国《新科学家》杂志近日报道称，随着南极游火爆，越来越多游客踏足南极大陆，使得原本与世隔绝、免疫系统脆弱的南极鸟类面临的病菌威胁增加，甚至可能会危及它们的生命。
Thanks t its awful envirnment，Antarctica remained largely untuched by humans fr thusands f years，allwing a grwing ecsystem t develp.Hwever，since the 1990s，the last true wilderness n the planet is becming an increasingly ppular destinatin fr adventure-seeking turists.Nw，a new study declares that the visitrs may be leaving behind harmful bacteria(细菌) which culd _________ the area's native bird numbers.
Humans can infect animals with illnesses such as the flu.Researchers，hwever，believed that the Antarctic animals weren't influenced by the danger due t the cntinent's extreme weather.Hwever, scientist Marta Cerdà-Cuéllar was nt cnvinced this was true.She and sme clleagues decided t examine waste samples frm Antarctic birds fr evidence f human bacteria.T ensure(确保) the waste was nt plluted，the scientists had t cllect it frm the birds themselves.
The results f their study shwed the presence f several types f human bacteria in the bird waste.This included a cmmn strain f bacteria that causes fd pisning in humans.The researchers say the bacteria kinds were resistant t cmmnly-used human antibitics(抗生素), prving they were brught in by the visitrs，rather than traveling birds.
“These strains，which are a cmmn cause fr infectins in humans and livestck，d nt usually cause death utbreaks in wild animals，”says Gnzález-Slís.“Hwever，the rising r invasive(扩散的) pathgens(病菌)that arrive t highly sensitive ppulatins culd have severe results and cause the extinctin f sme ppulatins.”The researcher als fears the presence f these bugs culd knw in advance the arrival f ther，mre deadly，pathgens as the number f turists peple increases.
Experts believe the nly way t prevent the mass damage f the birds is t impse stricter regulatins r，at least，put int effect the nes already in place.Fr example，while the Antarctica Treaty requires visitrs t carry their waste back hme t safeguard the ancient envirnment，the regulatin is rarely carried ut.Hpefully，fficials will take steps t prtect the vulnerable birds befre it's t late.
