目的了解本县感染性腹泻病原谱的构成情况和流行特征。方法采集哨点医院就诊的腹泻患者的粪便,进行病原学检测。结果采集哨点医院患者粪便796份,结果检出病原体阳性标本226份,检出率为28.39%。检出副溶血性弧菌84株,位居所有检出病原体的首位(占37.17%),与其他病原体检出率差异有统计学意义(P<0.05),其次是轮状病毒(占22.57%)、沙门菌(占15.04%),未检出霍乱弧菌和诺如病毒。流行特征为夏秋高发,8月达到高峰。病原菌对大多数抗生素敏感,但对氨芐西林和复方新诺明有一定的耐药性,副溶血性弧菌的耐药性普遍较低。结论宁海县感染性腹泻的主要病原菌为副溶血性弧菌、轮状病毒和沙门菌,应适时加强监测防控。病原菌对多数抗生素敏感,可用于预防和治疗。
Objective To understand the composition and epidemiology of infectious spectrum of infectious diarrhea in this county. Methods The stool samples of diarrhea patients in sentinel hospital were collected for pathogen detection. Results Seventy-six patients with sentinel hospital were collected, and 226 positive specimens were detected. The detection rate was 28.39%. 84 strains of Vibrio parahaemolyticus were detected, accounting for the first place among all the detected pathogens (accounting for 37.17%), showing a significant difference from other pathogens (P <0.05), followed by rotavirus (22.57% ) And Salmonella (15.04%). Vibrio cholerae and Norovirus were not detected. Popular features for the summer and fall, peaked in August. Pathogenic bacteria are sensitive to most antibiotics, but have some resistance to ampicillin and cotrimoxazole, and the resistance of Vibrio parahaemolyticus is generally low. Conclusion The main pathogens of infectious diarrhea in Ninghai County are Vibrio parahaemolyticus, rotavirus and Salmonella, and the prevention and control should be strengthened in time. Pathogenic bacteria sensitive to most antibiotics, can be used for prevention and treatment.
