乔治亚大学的研究者发现病原体如沙门氏菌可以在曲奇和饼干中存存活至少6个月!

佐治亚大学农业和环境科学学院杰出的名誉教授Larry Beuchat领导了一项研究,调查导致食源性疾病的细菌能在食物中存活多久。Beuchat说:“越来越多的食源性疾病与摄入受污染的干的食物有关。我们不期望沙门氏菌食物能够在非常干燥的环境中生长。”

Beuchat和共同作者David Mann发现,有害细菌不存可以在干燥食物如曲奇和饼干中存活,并且它们还可以活很久!

发表在Journal of Food Protection上的新研究,研究者从以前导致食源性疾病爆发的食物中分离出了5种不同血清型的沙门氏菌,从食物中分离出的菌很少。研究者将沙门氏菌放入4种不同夹心的曲奇和饼干中,并进行储存;用奶酪和花生酱作为饼干夹心,巧克力和香草作为曲奇夹心。

研究者发现不管什么夹心沙门氏菌均存活,不过不同夹心中沙门氏菌存活时间存在差异。Beuchat 说:“夹心饼干中沙门氏菌没有在曲奇中存活的久。”一些夹心中沙门氏菌可以存活6个月以上!

Beuchat和UGA的其他研究者了解沙门氏菌和其它食源性病原体,并意识到这些病原体可以在干燥食物上存活很长的时间。病原体为什么可以存在这么长的时间将是下一步防止污染、导致食源性疾病爆发的研究重点。

气候变暖或促进沙门氏菌爆发

沙门氏菌是一类相对常见的致病菌,其中的一些种类可能造成人类呕吐、发烧和腹泻等症状。而且这种菌常常因为不严格的卫生条件,而被混进食物中导致人们的食物中毒。以前有研究认为,这类菌的突然大量爆发可能与极端的天气相关,但是具体情况还需要进一步验证。美国马里兰州的研究者们分析了过去十年来沙门氏菌的数据,他们将天气与沙门氏菌的爆发建立起了联系。他们的研究认为,过去十年内的气候变暖趋势下导致了一些极端的气候情况

PLoS ONE:沙门氏菌引发感染的分子机制

近日,刊登在国际杂志PLoS ONE上的一篇研究论文中,来自诺维奇生物科学研究院的研究人员通过研究揭开了沙门氏菌组织其进行感染所需的基因表达的分子机制。 沙门氏菌是一种食源性致病菌,在很多时候其可以克服机体的天然防御屏障从而成功入侵我们的机体,因此理解其入侵机体的分子机制对于开发新型抑制策略来有效控制沙门氏菌感染非常重要。 大多数沙门氏菌感染会导致胃肠炎,细菌可以侵入到机体肠道的上皮细胞中

其实宿主免疫系统与病原体(广义:包括病变的自身组织)是一对哲上的矛盾。如果没有病原体的存在,免疫系统也就毫无意义。在进化过程中,宿主免疫系统与病原体在不断地调整自己,适应对方的特性,从而将自身的利益最大化。最近发表在《Cell:trends in immunology》杂志上的一篇综述类文章中,作者就沙门氏菌的感染方式与宿主的免疫策略做了系统的总结。 沙门氏菌是一类常见的寄生类微生物。最早见于美
