Comparison between bacillary dysentery and other infective diarrhea during early clinical stage

Objective To compare the epidemiological and clinical characteristics of bacillary dysentery and other infective diarrhea for better non-bacteriological diagnosis and differential diagnosis.Methods Epidemiology and clinical manifestations of 140 bacillary dysentery and 349 other infective diarrhea cases were retrospectively studied, Logistic regression analysis was used to screen the related factors for differentiating bacillary dysentery from other infective diarrhea.Results Peak seasonal difference was found statistically significant in the occurrence rate of bacillary dysentery and other infective diarrhea(P0.05),the former was in summer time and the latter in auturn.Fever, tenesmus,mucous stool,pus and blood stool and tenderness on left lower quadrant were found more frequent in bacillary dysentery cases than in other infective diarrhea,but nausea,vomiting,watery stool and loose stools were the main clinical characteristics of the latter(all P0.05).Logistic regression analysis showed that attacked season,tenesmus,fever,mucous stool and tenderness on left lower quadrant were proved to have significant correlation with clinical diagnosis of bacillary dysentery.Conclusion Fever,tenesmus,mucous stool,and tenderness on left lower quadrant are the main differential points between clinically diagnosed bacillary dysentery and other infective diarrhea.
