小儿腹泻的病原学研究

Studies on Bacterial Pathogens of Diarrhea in Children

我院自1990.6～1991.3月随机选择兰州部分地区12岁以下、病程在3天以内、未经抗菌治疗的急性腹泻患儿共158例,留取新鲜粪便标本,作细菌学培养,同时进行临床特点等观察。结果表明共检出病原菌86株,总检出率为54.43％,其中空肠弯曲菌检出率高于志贺氏菌及大肠杆菌而居首位。条件致病菌占总检出率的12.79％。158例中有12例同时检出两种病原菌,混合感染率7.59％。全部观察病例中,2岁以下年龄组发病占82.90％,病原谱最广,各种病原菌均有检出。

During the period from Jun. 1990 to Mar. 1991 in Lanzhou, 158 children under 12 years of age with acute diarrhea were studied for enteropathogenic bacteria. The results showed that the total isolation rate of bacterial pathogens was 54.43%. Of which, campylobacter jejuni was 16.45%. Its positive rate was higher than that of Shigella and Colibacillus. The total isolation rate of conditioal pathogenc bacteria was 12.79%. Among 158 cases, two kinds of bacterial pathogens were Isolated at the same time in 12 patients. The mixed infection rate was 7.59%. Among all of cases, infants under two years of age were 82.90%. The variant pathogenic bateria had been isolated in the two years old groups.
