目的分析引起患儿患细菌性腹泻疾病的病原微生物的种类,以及其耐药性。方法选取该院2014年4月-2015年4月收治的78例细菌性腹泻患儿作为研究对象,将上述患儿的粪便进行微生物检验,总结致病菌的分布,并对主要致病菌进行药敏实验,总结其耐药性。结果在选取的78例患儿粪便标本中,38例检测出致病菌,其检出的阳性率为48.72%,其中沙门氏菌有32例(84.21%),为导致该病的主要细菌,检测的其他致病菌有志贺菌、大肠杆菌、弧菌属和合并真菌感染。药敏试验显示,沙门氏菌对氨苄西林、头孢哌酮及头孢三嗪等抗生素都有较高的耐药性。结论沙门氏菌为引起患儿细菌性腹泻的最主要致病菌,该菌的耐药性较强,为临床治疗和预防患儿细菌性腹泻提供了方向。
Objective To analyze the types of pathogenic microorganisms that cause bacterial diarrhea in children and their drug resistance. Methods A total of 78 cases of bacterial diarrhea admitted to our hospital from April 2014 to April 2015 were selected as subjects. The stools of the children were tested for microbiology, the distribution of pathogens was summarized, and the main pathogenic bacteria Drug sensitivity test, summarizes its resistance. Results Of the 78 samples collected from 78 stool samples, 38 samples were detected as pathogenic bacteria and the positive rate was 48.72%. Among them, 32 (84.21%) were Salmonella, which were the main bacteria causing the disease. Other pathogenic bacteria have Shigella, Escherichia coli, Vibrio and fungal infection. Drug susceptibility tests showed that Salmonella has high resistance to antibiotics such as ampicillin, cefoperazone and ceftriaxone. Conclusions Salmonella is the most important causative agent of bacterial diarrhea in children, and its drug resistance is strong, which provides the direction for clinical treatment and prevention of bacterial diarrhea in children.
