| [摘要]目的：了解本地区儿童非伤寒沙门菌肠道感染的流行病学特点，并监测分析其对抗菌药物的敏感性，探讨阿奇霉素治疗肠道非伤寒沙门菌感染的可能性，为进一步控制非伤寒沙门菌感染提供科学依据。方法：回顾性分析2014年7月至2016年6月深圳市儿童医院确诊并住院治疗的76例肠道非伤寒沙门菌感染患儿的年龄、性别、发病季节等流行病学特点；采用纸片扩散法检测5种常用抗菌药物的敏感性，使用E-Test法和纸片扩散法检测阿奇霉素的最低抑菌浓度（MIC），并对阿奇霉素的MIC值与其抑菌圈直径进行直线相关回归分析。结果：76株非伤寒沙门菌属于4种血清群，以鼠伤寒沙门菌血清型和肠炎沙门菌血清型为主；1岁以下小婴儿54例，占71.05%；非伤寒沙门菌对复方磺胺甲恶唑、头孢曲松、氯霉素、奈定酸、氨苄西林的敏感性分别为73.68%、63.16%、60.53%、27.63%和22.37%；检出多重耐药非伤寒沙门菌16株，占21.05%；E-TEST法检测阿奇霉素对沙门菌的MIC为2~96 μg/mL，MIC50为3 μg/mL，MIC90为4 μg/mL；纸片扩散法检测其抑菌圈直径范围为6.50 ~19.75 mm，二者显著相关（P<0.01，︱r︱=-0.836)。结论：本地区儿童肠道感染的非伤寒沙门菌血清型多样，以小婴儿为主，多重耐药菌比例较高；检出的非伤寒沙门菌对阿奇霉素的基础数据可以作为以后临床应用的参考指标。 |

| Abstract: |
| [Abstract] Objective: To investigate the epidemiological characteristics of non-typhoid Salmonellosis (NTS) infection in children in this region, monitor its sensitivity to antibiotics, and explore the possibility of azithromycin in the treatment of intestinal NTS infection, so as to provide scientific basis for further control of NTS infection. Methods: A retrospective analysis was made on the epidemiological characteristics in terms of the age, gender and onset season in 76 children with NTS infection in Shenzhen Children's Hospital from Jul. 2014 to Jun. 2016. The sensitivity of five commonly used antibiotics was detected by disc diffusion method. The minimum inhibitory concentration (MIC) of azithromycin was detected by E-Test method and disc diffusion method, and the MIC value of azithromycin and its inhibition zone diameter linear regression were analyzed. Results: The 76 strains of NTS belonged to 4 serotypes, and Salmonella typhimurium serotype and Salmonella enteritidis serotype were the main serotypes. Totally 54 infants were under 1 year old, accounting for 71.05%. The sensitivity of NTS to compound trimoxazole, ceftriaxone, chloramphenicol, nalidixic acid and ampicillin were 73.68%, 63.16%, 60.53%, 27.63% and 22.37%, respectively. There were 16 strains of multi-drug resistant NSP, accounting for 21.05%. MIC of azithromycin by using E-TEST was from 2 to 96 μg/mL, 3 μg/mL for MIC50 and 4 μg/mL for MIC90. The diameter of the inhibition zone was determined by the disc diffusion method to be from 6.50 to 19.75 mm, which was significantly correlated (P<0.01, r-=-0.836). Conclusion: NTS infection in children in this region are diverse, mainly in small infants, with a high proportion of multi-drug resistance. The basic data of the detection of NTS against azithromycin can be used as a reference index for future clinical application. |
