1·There have been numerous well-documented extinctions of indigenous species caused by the introduction of non-indigenous predators and pathogens.
由于引入了非本地的捕食者和病原体，已经有许多本土物种灭绝的记录，证据确凿。
2·Many are found in tropical and subtropical areas of the world, where the accumulation of high concentrations of metals may afford some protection against plant-eating insects and microbial pathogens.
许多超富集植物被发现于热带地区和亚热带地区，在那里，高浓度金属元素的积累可以为植物提供保护来对抗以植物为食的昆虫和细菌病原体。
3·Caused by common pathogens were Streptococcus pneumoniae, Haemophilus influenzae and Moraxella bacteria Mora.
引起感染的常见病原体为流感嗜血杆菌、肺炎链球菌和卡他莫拉菌。
4·Though for most organisms the sudden appearance of new resistance is rare, this is not the case for all pathogens.
尽管对于大多数生物而言，突然出现新耐药性的情况很罕见，但也不是说所有病原体都如此。
5·In theory, yes, experts say. But the meat must be cooked, which will kill any noxious pathogens before you eat it.
专家说，理论上是安全的。但是这些肉必须煮熟，在你吃前必须杀死所有有害病原体。
1·But what we don't know is why they become susceptible to this host of pathogens, viruses and fungus.
但是我们没有弄明白的是为什么蜜蜂们会对这些病原菌，病毒和真菌这么敏感。
2·Prior studies have also linked colony collapse to different viruses and pathogens, but one researcher says viral sicknesses may be just one of the threats that bees face.
先前的研究也把蜂群的衰竭归因于不同的病毒和病原菌，但是有一个研究员称病毒性疾病只是蜜蜂面临的威胁之一。
3·Structurally, the appendix is isolated from the rest of the gut, with an opening smaller than a pencil lead, protected from the fecal stream that might be carrying pathogens.
从构造上看，阑尾位于盲肠的末端，不与其他部分连结。 它有一个比铅笔心还细的开口，防止了可能携带病原菌的废物流入其中。
4·Meanwhile, several types of animals have been shown to gain weight when injected with a virus known as adenovirus-36, indicating that pathogens may play a role in some cases of obesity.
同时，被注入腺病毒36型后，几种动物的体重都增加了，这表明病原菌某种程度上也可导致动物肥胖。
5·It is always just a question of time until the pathogens mutate and become insensitive. It's a never ending arms race.
病原菌突变产生耐药性，这永远只是个时间的问题，因此这是一场永远不会止步的武器竞赛。
1·The study has implications for research into subjects like disease transport by animals, since patterns of movement may affect to what extent pathogens are passed along.
这项研究给了研究人员研究其他一些学科的启示，例如动物传播疾病，动物的活动形式在何种程度上影响到致病菌的传播。
2·Polymerase chain reaction-based (PCR-based) and enzyme-linked immunoabsorbent assay (ELISA) methods are now applied in the detection of major food-borne pathogens.
依据聚合酶链反应(PCR)和酶联免疫吸附检测(ELISA)的方法目前被应用于主要食源性致病菌的检测。
3·Sometimes the consumer has to take independent action to avoid food-borne pathogens such as E. coli and salmonella.
有时候，消费者们需要采取一些自主行为来避免感染大肠杆菌和沙门氏菌这一类的食源性致病菌。
4·Results Duchesnea indica focke had strong inhibitory effects against the 7 common clinical pathogens.
结果蛇莓对金黄色葡萄球菌等7种常见致病菌有较强的体外抑菌作用。
5·Conclusion Gram positive organisms are major pathogens of bacteremia in critically ill patients.
结论革兰阳性球菌是危重病患者菌血症的重要致病菌。
