目的了解莱州市腹泻病原菌谱构成情况,为感染性腹泻防制提供依据。方法采集腹泻患者粪便标本,按GB/T 4789微生物学标准检验法进行细菌分离培养。结果共检测腹泻患者粪便标本231份,分离病原菌63株。其中副溶血弧菌13株(20.6%)、志贺菌12株(19.0%)、致泻性大肠埃希菌11株(17.5%)、气单胞菌10株(15.9%)、沙门菌6株(9.5%)、类志贺邻单胞菌3株(4.8%)、河弧菌、拟态弧菌、小肠结肠炎耶尔森菌和非脱羧莱克勒菌各2株(各3.2%)。结论莱州市感染性腹泻病原菌种类较多,除检测到常见腹泻病原菌外,还检测到2株罕见的腹泻病原菌非脱羧莱克勒菌。
Objective To understand the composition of pathogenic bacteria spectrum of diarrhea in Laizhou City and provide basis for prevention and control of infectious diarrhea. Methods Diarrhea patients stool specimens collected, according to GB / T 4789 Microbiology standard test method for bacterial isolation and culture. Results A total of 231 stool samples were collected from diarrhea patients and 63 pathogens were isolated. Among them, 13 strains of Vibrio parahaemolyticus (20.6%), 12 strains of Shigella (19.0%), 11 strains of diarrheal Escherichia coli (17.5%), 10 strains of Aeromonas (15.9%), (9.5%), 3 strains of Pseudomonas aeruginosa (4.8%), 3 strains of Vibrio cholerae, 2 strains of Mimicrobacterium villosum, 2 strains of Yersinia enterocolitica and 2 strains of non-decarboxylases (3.2% each). Conclusion There are more pathogens in infectious diarrhea in Laizhou City. In addition to the common pathogens of diarrhea, two rare non-decarboxylases of Klebsiella spp. Were identified.
