In addition to symptomatic treatment, some still need to use antimicrobial therapy for different pathogens. As the stool culture takes a long time and is not conducive to timely treatment, the author observed leukocyte classification counts in 238 children with acute gastroenteritis from January to October in 1981 and considered it as an easy and early method to diagnose infants and young children Effective method of acute gastroenteritis. The sensitivity of this method is 84.3%, the specificity is 74.5%. 238 children with routine laboratory methods for stool culture, white blood cell count and classification. According to the etiology of different sub-5 groups were compared: non-bacterial group 46
