Etiology of Diarrheal Disease Years in Shenzhen from 2013 to 2014 / 现代检验医学杂志

ABSTRACT

Objective Through the analysis of the pathogens distribution of out-patient department and emergency department patients with diarrhea from Shenzhen Hospital of Peking University in 2013~2014,so as to provide reference for the clinical diagnosis and treatment of diarrhea disease.While understanding the improved Salmonella detection results.Methods Var-ied pathogenic bacteria were isolated and identified from 1 719 diarhea stool samples of native Shenzhen Hospital of Peking University from 2013 to 2014 through enrich culture,separate culture,biochemistry,serology etc.Pathogenic virus were test-ed for 451 watery stool specimens by fluorescence PCR.Analyzed statistical differences between the direct inoculation and selenite cystine broth enrichment for Salmonella.Results Picked out 143 disease germs from 1 719 examples diarrhea pa-tient’s stool samples,among which there were 25 strains of ETEC,12 strains of EPEC,8 strains of EAEC,1 strains of EIEC,19 strains ofVibrio parahemolyticus,76 strains Salmonella,2 strains Shigella and 0 strain ofVibrio cholera.There were 10 samples with two disease germs timely.Picked out 189 disease viruses from 451 examples diarrhea patient’s stool without disease germs,among which there were 79 Rotaviruspositive,91 Norwalkvirus positive,9 Adenoviruspositive,10 Astrovirus positive.There were 4 samples with Rotavirus and Norwalkvirus timely.After Salmonella ways to improve the positive rate of 0.6% (17/2 627)increased to 4.4% (76/1 719),χ2=67.2,P<0.01,the difference was statistically signifi-cant.Conclusion The detectable rate of Salmonella and Norwalk virus was the majority,and the clinic enhance the test of the diarrhea pathogenic microorganism,including the improvement of detection method,to reduce the missing rate of them,to provide the scientific basis for the diagnostical therapectic measures.
