令人欣慰的是，我们关于线虫在苏云金芽孢杆菌（Bt）生态学中的作用的观点文章[1]引发了对这一主题的辩论。Loguercio和Argôlo-Filho [2]认为，有足够的证据表明Bt是一种可以在广泛的环境小生境和宿主中生存和增殖的细菌。此外，他们认为，Bt，作为一个物种，已经进化直接作为人类活动的结果，加速了昆虫病原和杀线虫菌株的出现。后者是一个有趣的想法，但超出了本答复的范围。我们主要担心的是Bt可以在昆虫或线虫宿主之外“增殖”和“茁壮成长”。我们只是不相信，目前有足够的证据表明，这种细菌可以做更多的不仅仅是生存在其主要宿主之外。虽然不想重复我们在原始文章中提出的论点[1]，但我们想解决上述作者提出的一些论点：（i）Bt可以在原生动物中繁殖。
It is gratifying to know that our opinion article [1] on the role of nematodes in the ecology of Bacillus thuringiensis (Bt) has stimulated debate on this topic. Loguercio and Argôlo-Filho [2] believe that there is sufficient evidence to consider Bt as a bacterium that can survive and proliferate in a wide range of environmental niches and hosts. Furthermore they suggest that Bt, as a species, has evolved directly as a result of anthropogenic actions which hastened the appearance of entomopathogenic and nematicidal strains. The latter is an interesting idea but one that is beyond the scope of this reply. Our main concern is the belief that Bt can ‘proliferate’and ‘thrive’outside of an insect or nematode host. We are just not convinced that there is currently sufficient evidence that this bacterium can do much more than simply survive outside of its primary host. While not wanting to repeat the arguments made in our original article [1] we would like to address some of those made by the above authors:(i) Bt can reproduce in protozoa.
