摘要

炭疽杆菌是炭疽病的人畜共患病原体。它的感染形式是孢子，可以在土壤中持续存在。食草动物通常通过在孢子污染的地方放牧而感染这种疾病。关于土壤中炭疽杆菌的活动，有两个学派。有人认为，这种细菌是专性动物寄生虫，土壤孢子在被另一种动物宿主吸收之前保持惰性。其他人认为，孢子可以在土壤中发芽，细菌会复制并重新形成孢子，以维持和/或增加孢子数量。这篇综述讨论了炭疽杆菌的土壤复制是否是其生命周期的重要组成部分。

Does environmental replication contribute to Bacillus anthracis spore persistence and infectivity in soil?

Bacillus anthracis is the zoonotic causal agent of anthrax. Its infectious form is the spore, which can persist in soil. Herbivores usually acquire the disease from grazing in spore-contaminated sites. There are two schools of thought regarding B. anthracis activities in soil. One contends the bacteria are obligate animal parasites and soil-based spores remain inert until taken up by another animal host. Others contend that spores can germinate in soil and the bacteria replicate and re-sporulate to maintain and/or increase spore numbers. This review discusses whether soil replication of B. anthracis is an important part of its life cycle.

期刊介绍： Research in Microbiology is the direct descendant of the original Pasteur periodical entitled Annales de l''Institut Pasteur, created in 1887 by Emile Duclaux under the patronage of Louis Pasteur. The Editorial Committee included Chamberland, Grancher, Nocard, Roux and Straus, and the first issue began with Louis Pasteur''s "Lettre sur la Rage" which clearly defines the spirit of the journal:"You have informed me, my dear Duclaux, that you intend to start a monthly collection of articles entitled "Annales de l''Institut Pasteur". You will be rendering a service that will be appreciated by the ever increasing number of young scientists who are attracted to microbiological studies. In your Annales, our laboratory research will of course occupy a central position, but the work from outside groups that you intend to publish will be a source of competitive stimulation for all of us."That first volume included 53 articles as well as critical reviews and book reviews. From that time on, the Annales appeared regularly every month, without interruption, even during the two world wars. Although the journal has undergone many changes over the past 100 years (in the title, the format, the language) reflecting the evolution in scientific publishing, it has consistently maintained the Pasteur tradition by publishing original reports on all aspects of microbiology.
