解放以来,菌痢的发病数已大为减少,但由于传染源不易管理与消除,传播途径复杂多样,痢疾杆菌型别繁多,缺乏交叉免疫力,简便有效之特异性预防措施仍未能推广,耐药菌株日见增多,慢性患者不易根治等原因,因此,要控制、消灭菌痢仍然是一项重要而又艰巨的任务。 Since the liberation, the incidence of bacillary dysentery has been greatly reduced, but due to the source of infection is not easy to manage and eliminate, the transmission is complex and diverse, dysentery bacilli various types, the lack of cross immunity, simple and effective specific preventive measures have not been able to promote, Due to the increasing number of drug-resistant strains, chronic patients are not easy to cure and other reasons, therefore, to control and eliminate bacillary dysentery is still an important and arduous task.
