198例婴幼儿腹泻的病原学分析

An analysis of the pathogen test results of 198 cases of infantile diarrhea

目的观察总结引起婴幼儿腹泻的病原微生物种类及其病原分布特点。方法对198例婴幼儿腹泻患者的粪便标本进行病原微生物检测,并对检测结果进行统计分析。结果 198例婴幼儿腹泻的粪便标本中,共检出病原微生物138例(69.70%),其中致病菌22例(15.94%),病毒116例(84.06%),其中以轮状病毒感染率最高(57.57%),明显高于致病菌检出率(P<0.05)。致病菌引起的婴幼儿腹泻主要发生在夏秋季,轮状病毒引起的婴幼儿腹泻主要发生在冬春季。6个月～3岁婴幼儿轮状病毒阳性率(71.43%)明显高于<6个月者阳性率(48.89%)及>3岁者阳性率(49.12%)(P<0.05)。结论婴幼儿腹泻的主要原因为轮状病毒感染,常见于6个月～3岁婴幼儿。

Objective To understand the pathogenic microorganism species and the distribution characteristics of these species that cause diarrhea in infants and young children.Method Stool specimens were collected from 198 cases of infantile diarrhea for the detection of pathogenic micro-organisms and the were subjected to statistical analysis.Results Pathogenic microorganisms were detected in 138 cases（69.70%） of the 198 cases of infantile diarrhea.Pathogens were found in 22 cases（15.94%）.The virus was found in 116 cases（84.06%）.Rotavirus infection accounted for 57.57%,which was significantly higher than that of pathogen detection rate（P0.05）.Infantile diarrhea caused by bacteria occurs mainly in summer and autumn,infantile diarrhea caused by rotavirus occurs mainly in winter and spring.6 months to 3 years old infants with rotavirus-positive rate（71.43%） was significantly higher than the 6 months,the positive rate（48.89%） and 3 years of age positive rate（49.12%）（P0.05）.Conclusion Infantile diarrhea was mainly caused by rotavirus infection common in infants and young children of 6 months to 3 years old.
