目的 :观察耐药伤寒病人病后不同时间的排菌规律 ,为有效地隔离、治疗和控制传染源提供依据。方法 :对经病原学证实的 32例耐药伤寒病人 ,定期采集大便进行病原分离鉴定。结果 :恢复期第 1至 5周检出率最高为 5 3.13% ,随时间延长 ,检出率递减 ;恢复期排菌持续时间为 0至 179天不等 ;女病人带菌时间较长。结论 :耐药伤寒病人恢复期排菌率仍高 ,慢性带菌时间长 ;伤寒防治中要注意恢复期病人和带菌者的隔离、治疗和监测
OBJECTIVE: To observe the law of bacteria discharging at different time after drug-resistant typhoid fever in patients, so as to provide the basis for effectively isolating, treating and controlling the source of infection. Methods: Thirty-two cases of drug-resistant typhoid fever confirmed by etiology were collected regularly to identify the pathogen. Results: The highest detection rate was 5 3.13% in the first week to the fifth week of convalescence. With the prolongation of time, the detection rate decreased gradually. During the convalescent recovery period, the duration of colonization ranged from 0 to 179 days. Conclusions: The recovery rate of patients with drug-resistant typhoid fever is still high, and chronic infection takes a long time. Isolation, treatment and monitoring of convalescent patients and carriers should be paid attention to in the prevention and treatment of typhoid fever
