1. The results showed that the f fragment , 728bp in length , could be a new gene with a little homology to the genes coding for polyketide synthetase or fatty - acid synthetase and the b fragment , about 4kb in length , is inferred to have repeat sequences around tn5 insertion site , in which there is homology to the wa 314 right arm of the high - pathogeniciry island of yersinia enterocolitica . to reveal any pathogenicity of enterobacter cloacae b8 and its mutated strains b8b and b8f to animals , the experiment with mice was carried out
   结果显示， f片段长度为728bp ，与现有生物数据库的blast比较分析，发现该序列仅有局部短于1oobp的区域与polyketide合成酶基因或与脂肪酸合成酶基因有低的同源性，推测为一新基因； b片段长约4kb ，序列拼接结果推测靠近tn5插入位点部位有重复序列，对b片段tn5远端的部分序列进行blast比较，发现它与小肠结肠炎耶尔森氏菌的强毒力岛有一定的同源性。

1. a waste pipe that carries away sewage or surface water
   同义词：sewer, sewerage
2. (zoology) the cavity (in birds, reptiles, amphibians, most fish, and monotremes but not mammals) at the end of the digestive tract into which the intestinal, genital, and urinary tracts open

百科释义

In zoological anatomy, a cloaca () is the posterior opening that serves as the only opening for the intestinal, reproductive, and urinary tracts of certain animal species. All amphibians, birds, reptiles, and monotremes possess this orifice, from which they excrete both urine and feces, unlike most placental mammals, which possess two or three separate orifices for evacuation.
