Methods: With serological and molecular techniques, we study chemical property, plasmid, CT gene and drug resistance of sporadic outbreak of vibro cholera in Shenzhen city. 方法:采用血清学和分子生物学相结合的方法,研究深圳地区散发不同血清型霍乱弧菌的生化特性、质粒、肠毒素基因携带和耐药状况。
Results: The sporadic outbreak of vibrio cholera has some characters: including non toxic strain infection, low detection rate of plasmid and CT gene and increase of drug resistance. 结果:散发性霍乱以无毒株为主,质粒及肠毒素基因的携带率极低,但耐药性有所增加。
