挪威数十只狗突然死亡，死因不详

It all started earlier this month. Veterinarians in Oslo, Norway were reportedly flummoxed by a rising number of sick dogs being brought to their practices. The pets appeared to be suffering from some sort of mysterious bowel disease, with similar signs of vomiting and bloody diarrhoea.

这一切都始于本月初。据报道，挪威奥斯陆的兽医们对越来越多的病狗被带到他们的诊所感到困惑。这些宠物似乎患有某种神秘的肠道疾病，有类似呕吐和带血腹泻的症状。

What had started in the capital city soon spread to most other regions of the country, sickening as many as 200 dogs, according to Norway's Veterinary Institute. By late Tuesday, the estimated death toll had risen to 26. On Wednesday, five new cases were added to the list.

据挪威兽医研究所(norwegian Veterinary Institute)的数据，始于首都的疫情很快蔓延到挪威其他大部分地区，导致多达200只狗患病。截至周二晚间，估计死亡数量已升至26人。周三，名单上又增加了5例新病例。

The news has so frightened dog owners in Norway, visitors crashed the Norwegian Kennel Club's website in a flurry for information.

这一消息让挪威的狗主人们非常害怕，游客们纷纷登录挪威养犬俱乐部的网站来获取信息。

Even the experts are worried and baffled, searching desperately for answers. The emergency and safety director of the Veterinary Institute Jorun Jarp toldlocal media it was "naturally alarming to have healthy Norwegian dogs dying so quickly."

甚至专家们也感到担心和困惑，拼命地寻找答案。兽医研究所的紧急和安全主任Jorun Jarp告诉当地媒体，“健康的挪威狗这么快就死了，这自然令人担忧。”

"This is a very special situation," he said, according to a translation from The Guardian. "I haven't been in involved in anything like it before."

据《卫报》的翻译，他说:“这是一个非常特殊的情况。”“我以前从未参与过类似的事情。”

No one knows what the heck is going on, or even if these deaths are all connected. Post-mortem examinations have uncovered nothing sinister, and rat poison, Campylobacter and Salmonella have all been ruled out.

没有人知道到底发生了什么，甚至没有人知道这些死亡是否都有关联。尸检没有发现任何有害物质，鼠毒、弯曲杆菌和沙门氏菌都被排除在外。

So far, there are only two types of bacteria that have been found in these dogs at unusual levels, and while these strains are sometimes responsible for diarrhoea in humans, it's currently unclear whether they're to blame for the recent outbreak.

到目前为止，在这些狗身上只发现了两种不同寻常水平的细菌，虽然这些菌株有时会导致腹泻，但目前还不清楚它们是否应该为最近的疫情负责。

To cover all possibilities, Norway's Food Safety Authority is also investigating mushrooms, viruses, other bacteria and parasites.

为了涵盖所有可能性，挪威食品安全局也在调查蘑菇、病毒、其他细菌和寄生虫。

But while the symptoms between canines are remarkably similar, without some sort of distinct biomarker to go by, officials just can't be sure the dogs are even suffering from the same thing.

但是，虽然两种狗的症状非常相似，但没有某种独特的生物标志物作为依据，官员们只是不能确定这些狗是否患有同样的疾病。

Food safety authority spokesman Ole-Herman Tronerud told a national Norwegian broadcaster that the illness seemed "very serious for a dog. But we don't know yet whether this is contagious or just a series of individual cases".

食品安全局发言人Ole-Herman Tronerud告诉挪威一家国家广播公司，这种疾病“对一只狗来说非常严重”。但我们还不知道这是传染性的，还是只是一系列个案。”

As long as the situation is unclear, officials suggest dog owners avoid close contact with other dogs, walking their dogs with a leash and avoiding dog shows. There are currently no signs this mysterious disease can spread to humans.

只要情况尚不清楚，官员们建议养狗者避免与其他狗狗亲密接触，遛狗时要系上狗链，避免参加狗展。目前还没有迹象表明这种神秘的疾病会传染给人类。
