目的:了解澂江县不同人群抗体水平及病原学情况,为伤寒副伤寒的预防和控制提供依据。方法:收集疫情资料,对不同人群伤寒副伤寒抗体水平及病原学进行监测,对分离到的菌株进行耐药分析。结果:正常人群抗体水平测定O抗体≥80为17.51%,H抗体≥80为4.3%;重点人群监测血培养阳性率2.97%,均为甲型副伤寒沙门菌;抗体监测阳性率33.13%;药敏试验对阿莫西林/棒酸100%敏感,利福平100%耐药。结论:我县流行的为甲型副伤寒,对同一份血标本用抗体水平及病原学两种方法同时检测以提高检出的阳性率;人群隐形感染较为普遍,应采取综合性的防控措施进行预防和控制。
OBJECTIVE: To understand the antibody levels and etiology of different populations in Qijiang County, and to provide basis for the prevention and control of typhoid and paratyphoid fever. Methods: Epidemic data were collected, the antibody levels and pathogenicity of typhoid and paratyphoid fever in different populations were monitored, and the drug resistance of the isolated strains was analyzed. Results: The antibody level of normal population was 17.51% for O antibody ≥80 and 4.3% for H antibody ≥80. The positive rate of blood culture in key population was 2.97%, both of which were Salmonella paratyphi A. The positive rate of antibody detection was 33.13%. Sensitivity test for amoxicillin / clavulanic acid 100% sensitive, rifampicin 100% resistant. Conclusion: Mycobacterium paratyphoid epidemic is the most common in our county, and the same blood sample is detected by both antibody level and etiology at the same time to improve the positive rate of detection. Invisible infection in the population is more common, and comprehensive prevention and control measures should be taken For prevention and control.
