Summer's here and with it come picnics, barbecues and of course Salmonella.
夏天到了，野餐和燒烤必不可少，當然還有沙門氏菌。
The germ is notorious for contaminating a variety of favorite warm-weather foods.
這種細菌就是以感染各種令人喜愛的燒烤類熱食物而臭名遠揚。
But the bacteria's palate is more limited than ours.
但是這種細菌的食量同我們人類相比要有限得多。
Once Salmonella makes its way into your system, it relies on a single unusual nutrient to survive.
一旦沙門氏菌進入你的身體，它會依靠一種不同尋常的營養物生存。
That's according to a study in the journal PLOS Pathogens.
這是根據在《公共科學圖書館病原體》期刊上的一項研究得出的結論。
Most people tough it out when they get food poisoning from Salmonella.
大多數吃了被沙門氏菌感染食物的人會選擇挺過去。
That's because treatment with antibiotics would eliminate the infection, but also get rid of the gut bacteria that promote good health.
那是因為如果用看抗生素來治療會消除感染，也會去除有益于身體健康的腸道細菌。
To figure out how to target Salmonella specifically, researchers screened for genes vital for the microbe's survival during the active phase of infection.
為了弄清楚如何才能只消滅沙門氏菌，研究人員篩查了沙門氏菌感染活躍期對其生存至關重要的基因。
And they identified a cluster of five genes that work together to allow the bacteria to digest a molecule called fructose-asparagine.
他們所鑒定出的一個包含5個基因的基因組共同努力促使沙門氏菌得以消化一種叫做果糖-天冬酰胺的分子。
No other organisms are known to use this chemical for fuel, so starving Salmonella of it could be a new strategy for fighting this foodborne bug while leaving desirable intestinal inhabitants unharmed.
據我們所知，沒有其他生物體以這種化學物質為食，所以讓沙門氏菌挨餓既能對抗這種食源性細菌，又可以保障身體腸道內的有益菌安然無恙。
Next, the researchers plan to see which foods contain large amounts of Salmonella's go-to snack.
接下來，研究人員計劃尋找一下什么食物里含有大量的沙門氏菌首選的零食。
But please, don't send unsolicited samples of Aunt Agnes's egg salad.
但是請不要寄來艾格尼絲阿姨雞蛋沙拉這樣不明所以的樣本。
