1·He says this naturally leads one to ask: "Does that non-human isolated strain of the same species cause the same effect?"
他说这会引起一个问题：从非人类处分离出来的同种类菌株是否引起的反应也一样？
2·The results suggest the reason why males of other species die faster than females may be the stress and strain of competition, the authors said.
研究还揭示出，在其他物种中雄性比雌性早死的原因可能是竞争的压力过大。
3·Before 1997 WNV was not considered pathogenic for birds, but at that time in Israel a more virulent strain caused the death of different bird species presenting signs of encephalitis and paralysis.
在1997年以前，西尼罗河病毒并未被认为对鸟类具有致病性，但就在那时，以色列出现了一种能够导致多种鸟类出现脑炎和麻痹症状继而死亡的毒力更强的毒株。
4·It is likely that the "s" strain is the ancestral species because it is found all over sub-Saharan Africa, whereas the "M" strain is concentrated on central and west Africa.
S类可能是更原始的种群因为它被发现存在于撒哈拉沙漠以南的非洲的各地。
5·The analyses showed that RAPD is able to differentiate mainly at the species level, while ERIC is effective at the strain level and therefore more consistent with cultivation characteristics.
分析表明，RAPD方法主要在种的水平上进行鉴别，而ERIC则可以在菌株水平上进行鉴别，结果与菌株栽培性状更为一致。
6·In order to study and analyze the species and bacteriorhodopsin (BR) protein resource, a strain of extremely halophilic archaea AB3 was isolated.
为了研究分析嗜盐古生菌物种与细菌视紫红质(BR)蛋白基因资源，分离纯化得到极端嗜盐古生菌ab3。
7·The polyacrylamide gel electrophoretic patterns of different species strains or the same strain after various treatments of animal and avian mycoplasmas were compared.
对不同菌种、不同菌株或同一菌株经不同处理后的牛、猪、鸡支原体用聚丙烯酰胺凝胶电泳进行比较。
8·The values of DNA-DNA homology between type strains of these species were less than 70%, which showed that strain SH2672 (representative strain of new group) represented a new rhizobial species.
且分支内各种间DNA同源性低于70％，表明它们分别为不同的种，菌株SH2672代表着一个新的根瘤菌种。
9·And the study on acid-production conditions of MD strain has proved that it belongs to anaerobe species and it has good acid-production power.
经对MD菌株产酸条件的初步研究，证实该菌属于兼气性厌氧菌，有较好的产酸能力。
10·As the world now knows, Mexico was the first country affected by a new and deadly strain of influenza that has leapt the species barrier from pigs to people. The first, but not the last.
现在全世界众所周知，最近一种致命的流感新品种，跨越生物种的藩篱，从猪只传染到人类身上，而且墨西哥是新病毒袭击的全球第一个国家，显然也不是最后一个国家。
