得克萨斯星-耐链霉素株(Texas Star-SR)是El Tor小川型霍乱弧菌3083株、经亚硝基胍处理而获得的减毒突变株。反复多次检查证明,它是一种能产生丰富的B亚单位、检不出A亚单位、不具全毒素特性的稳定的
The Texas Star-SR strain is an attenuated mutant of El Tor Ogawa-type Vibrio cholerae 3083 strain treated with nitrosoguanidine. Repeated checks show that it is a stable B subunit that produces abundant subunit A, which can not detect subunit A and is not fully toxic
