Methods: With serological and molecular techniques, we study chemical property, plasmid, CT gene and drugresistance of sporadic outbreak of vibro cholera in Shenzhen city.
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 drugresistance.
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。
