Abstract

Sixteen freeze-thaw-injured nonculturable stocks of Campylobacter jejuni were passed through rat gut, and seven were reisolated. These reisolated strains were converted to toxin producers, as they were before preservation, following consecutive passages through rat gut. This observation indicated the existence of an injured, viable, but nonresuscitated form of C. jejuni which can be resuscitated to a culturable and fully virulent form by passaging the organism through a susceptible host.

摘要

16株经冻融损伤的空肠弯曲菌非可培养菌悬液通过大鼠肠道,其中7株被重新分离出来。这些重新分离出的菌株在连续通过大鼠肠道后,如同保存前一样,转变为毒素产生菌。这一观察结果表明存在一种损伤的、存活但未复苏的空肠弯曲菌形态,通过将该菌通过易感宿主传代,其可复苏为可培养且具有完全毒力的形态。
