原声例句
Osmosis-微生物 This capsule is a major virulence factor because of its antiphagocytic ability. 荚膜具有抗吞噬的作用，所以是其主要的毒力因子。 Osmosis-微生物 The capsule is considered an important virulence factor since the strains that lack a capsule are less virulent. 荚膜被认为是重要的毒力因子，因为缺少荚膜的菌株毒力相对较弱。 Osmosis-微生物 Some bacteria can also have another extra layer on top of the cell wall called a capsule, which is a major virulence factor. 一些细菌还有包裹在细胞壁外面的荚膜，是主要的毒力因子。 Osmosis-微生物 Now, Klebsiella pneumoniae has a number of virulence factors that are like assault weaponry that help it attack and destroy the host cells and evade the immune system. 肺炎克雷伯杆菌具有多种毒力，可以攻击宿主细胞，并逃避免疫。 Osmosis-微生物 It has a bunch of virulence factors such as capsule, LPS, pili, and a siderophore, which helps the bacteria to attack and destroy the host cells and evade the immune system. 它具有多种毒力因子，如荚膜、脂多糖、菌毛以及铁载体；铁载体帮助细菌攻击宿主，破坏机体细胞，并逃避人体免疫。 Osmosis-微生物 Currently, little is known about the pathogenesis of this bacteria, but we do know that it possesses a number of virulence factors, which are like assault weaponry that help it attack and destroy the host cells. 目前而言，对该种细菌致病机制的研究尚不充分，但是我们已经了解到其具有多种可能攻击并杀死宿主细胞的毒性因子。

Virulence factor（重定向自Virulence factors）
Virulence factors are molecules produced by pathogens (bacteria, viruses, fungi and protozoa) that contribute to the pathogenicity of the organism and enable them to achieve the following: Specific pathogens possess a wide array of virulence factors. Some are chromosomally encoded and intrinsic to the bacteria (e.g. capsules and endotoxin), whereas others are obtained from mobile genetic elements like plasmids and bacteriophages (e.g. some exotoxins). Virulence factors encoded on mobile genetic elements spread through horizontal gene transfer, and can convert harmless bacteria into dangerous pathogens. Bacteria like Escherichia coli O157:H7 gain the majority of their virulence from mobile genetic elements. Gram-negative bacteria secrete a variety of virulence factors at host-pathogen interface, via membrane vesicle trafficking as bacterial outer membrane vesicles for invasion, nutrition and other cell-cell communications. It has been found that many pathogens have converged on similar virulence factors to battle against eukaryotic host defenses. These obtained bacterial virulence factors have two different routes used to help them survive and grow: |
