Vibrio cholerae NRT36S is a non-cholera toxin-producing, non-O1 strain that causes diarrhea in volunteers. The genome of NRT36S was sequenced to create a draft containing 174 contigs plus the superintegron region. Our analysis of the draft genome revealed several putative toxin genes and colonization factors. Besides confirming the existence of nonagglutinable heat-stable toxin, we also identified the genes for a type three secretion system, a putative exotoxin, two different RTX toxins, and four pilus systems.
霍乱弧菌NRT36S是一种不产生霍乱毒素的非O1菌株,可使志愿者出现腹泻症状。对NRT36S的基因组进行了测序,以创建一个包含174个重叠群加上超级整合子区域的草图。我们对该基因组草图的分析揭示了几个推定的毒素基因和定植因子。除了证实不可凝集热稳定毒素的存在外,我们还鉴定出了一个三型分泌系统、一种推定外毒素、两种不同的RTX毒素以及四种菌毛系统的基因。
