1981年10～12月采取54例婴幼儿秋季腹泻忠儿的粪便标本,应用电镜直接观察和细菌培养法进行病原学研究。从38例的粪便中检查到轮状病毒,阳性率为7O.4％;其中2例同时发现冠状病毒。均末检出肠道致病菌。病毒阳性率似与粪便外观性状无关。1例患儿在发生腹泻2个月后从粪便中检出轮状病毒。上述结果表明,轮状病毒是合肥地区婴幼儿秋季腹泻的主要病原。
From January to December 1981, 54 cases of stool samples from infants and young children with diarrhea-infantile bowel syndrome were collected and directly studied by electron microscopy and bacterial culture. Rotavirus was detected from the faeces of 38 cases, with a positive rate of 70.4%. Two of them also detected the coronavirus. No intestinal pathogenic bacteria were detected. The positive rate of the virus has nothing to do with the appearance of faeces. One patient had rotavirus detected in the stool after two months of diarrhea. The above results show that rotavirus is the main pathogen of infantile autumn diarrhea in Hefei.
