Identification of Bacillary Dysentery from Other Infectious Diarrhea

OBJECTIVE To obtain the primary differential items between bacillary dysentery and other infectious diarrhea through risk factor analysis.METHODS The epidemiology and clinical manifestation of 138 bacillary dysentery patients and 205 other infectious diarrhea patients were investigated.The Logistic regression was used to screen the correlation factors to differentiate bacillary dysentery from other infectious diarrhea.RESULTS The mean temperature of bacillary dysentery patients was(38.4±0.7)℃,while that of other infectious diarrhea was(38.1±0.6)℃(P=0.023).Bacillary dysentery patients with tenesmus and mucous stool were 34.1% and 55.8%,respectively but of 11.7% and 1.5% of other infectious diarrhea patients(P0.0001).The possibility of clinically diagnosed bacillary dysentery increased along with the temperature of diarrheal patients raised,and the possibility when diarrheal patients with tenesmus were 3 times of with out tenesmus,and that with mucous stool were 60.5 times of with watery stool.CONCLUSIONS Fever,tenesmus and mucous stool are the primary differential points between clinically diagnosed bacillary dysentery and other infectious diarrhea.
