目的了解西安市2008-2014年沙门氏菌感染情况,为腹泻病监测工作提供科学依据。方法采集西安市2008-2014年腹泻病哨点医院腹泻病人粪便标本,对其进行常规沙门氏菌病原学分离鉴定。结果采集粪便标本2113份,沙门氏菌检出34株,检出率为1.61%,其中汤卜逊沙门氏菌和鼠伤寒沙门氏菌各检出12株,鸡伤寒沙门氏菌检出4株,山夫登堡沙门氏菌和未分型各3株,以汤卜逊沙门氏菌和鼠伤寒沙门氏菌为主。年龄特征分布中,0~5岁年龄组发病最多,占50.00%;6~10岁组居中,占20.59%;11~19岁组次之,占17.65%;其余年龄组较少,差异有统计学意义(χ~2=102.000,P<0.05)。季节特征分布中,7月和8月发病最多,其他月份较少,差异有统计学意义(χ~2=34.000,P<0.05)。34株沙门氏菌对阿莫西林/克拉维酸、头孢吡肟、氨曲南、氯霉素、四环素敏感度较高。结论西安市沙门氏菌感染主要以汤卜逊沙门氏菌和鼠伤寒沙门氏菌为主,低年龄组及季节流行特征明显,沙门菌耐药趋势明显。
Objective To understand the status of Salmonella infection in Xi’an from 2008 to 2014 and provide a scientific basis for the surveillance of diarrhea. Methods Stool specimens of diarrhea patients from the sentinel hospital of diarrhea in Xi’an during 2008-2014 were collected and routinely isolated and identified by pathogenic Salmonella. Results A total of 2113 samples of stool samples were collected, 34 of which were detected by Salmonella, with a detection rate of 1.61%. Among them, 12 strains of Salmonella tybus and Salmonella typhimurium were detected, 4 strains of Salmonella typhi, 4 strains of Salmonella typhi, Three strains were classified into Salmonella typhimurium and Salmonella typhimurium. Among age distributions, 0 to 5 years old group had the most incidence, accounting for 50.00%; 6 to 10 years old group, accounting for 20.59%; 11 to 19 years old group, accounting for 17.65%; other age groups were less, the difference was statistically Significance (χ ~ 2 = 102.000, P <0.05). In the distribution of seasonal features, the incidence was highest in July and August, while the others were less, the difference was statistically significant (χ ~ 2 = 34.000, P <0.05). 34 strains of Salmonella were more sensitive to amoxicillin / clavulanic acid, cefepime, aztreonam, chloramphenicol and tetracycline. Conclusions Salmonella typhimurium in Xi’an is dominated by Salmonella Thompson and Salmonella typhimurium, with obvious characteristics in low age group and seasonal epidemic. The trend of Salmonella resistance is obvious.
