用抗菌素治疗伤寒病在多数的情况是有效的。然而长期连续不断的服用不可能完全防止重发及伤寒带菌者的形成。有的是急性转变成慢性,有的是形成长期的带菌。免疫预防伤寒病的带菌者主要在病的最早阶段进行。在用氯霉素治疗的同时结合皮下注射化学纯的伤寒制剂Vi一抗原。在皮下注入Vi一抗原以后局部反应很少明显者或轻微的充血,在注射的底部有限量的浸润和短时间的疼痛;一半病例有体温升高,但在注射后的短时间内消失。综合免疫一抗菌素治疗方案1:用氯霉素的平 Antibiotic treatment of typhoid fever is effective in most cases. However, long-term continuous use can not completely prevent the recurrence and typhoid carriers of the formation. Some are acute into chronic, some form long-term carrier. Immunization against typhoid carriers mainly in the earliest stages of disease. While treated with chloramphenicol, subcutaneously injected with a chemically pure typhoid Vi antigen. Local reactions were less pronounced or mildly hyperemic after subcutaneous instillation of Vi-1 antigen with limited infiltration and short-term pain at the bottom of the injection; in half cases there was an increase in body temperature but disappear shortly after injection.
