AIM To demonstrate the etiologic pathogens of acute diarrhea in children and the diagnostic value of stool pH. METHODS From May 1988 to April 1992, 368 children with acute diarrhea were studied. Fresh stools were examined routinely, and stool pH were tested with pH paper, then the samples in the culture medium of the Cary Blair were sent to the lab for bacteria isolation and identification. The rotavirus was identified by the method of ELISA from the supernatant. RESULTS Thirty one pathogens and 385 bacteria strains were found in the 368 examples, with a detectable rate of 67 7%, including 37 8% of mixed infections. Among bacteria families, vibrionaceae is the most common (39 7%), and among bacteria genuses, aeromonas is the most common (26 8%). In bacterial diarrhea, the stool pH tends to be basic while in viral diarrhea to be acid. CONCLUSION There are 31 pathogens for the children′s acute diarrhea in this area. It is quite difficult to make an etiologic diagnosis only by clinial signs. However, stool pH is of some value for early diagnosis of the disease.
