摘要
对无脊椎动物，如毛虫的研究正在为鉴定与人类细菌感染相关的基因提供一种廉价，简单而又安全的方法。英国巴斯大学的研究者已经发现一种可以分选大量细菌基因序列的方法，这种方法是在毛虫体内通过观票细面基因对冥免疫糸统的反应进行的。这种被称为快速致死毒性评注（RVA）的新技术可以使用毛虫筛查出编码造成具有致死毒性的基因。
Invertebrates such as caterpillars are helping to provide a cheap, easy and safe way to identifl the genes associated with bacterial infection in humans. Researchers from the University of Bath in the UK have discovered a way to sort through large numbers of bacterial gene sequences by testing them in caterpillars to see how their immune systems respond. This new technique, known as rapid virulence annotation （RVA） allows them to pinpoint the genes which code for virulence.
