[Pathogenic surveillance and related factors on bacillary dysentery in Beijing, 2008-2017].

To analyze the pathogenic surveillance programs and related factors on bacillary dysentery in Beijing, 2008-2017, to provide evidence for the practices of diagnosis, treatment and prevention of the disease. Analysis was conducted on surveillance data of bacillary dysentery, collected from the surveillance areas of national bacillary dysentery in Beijing. positive rate of stool samples were used as the gold standard while detection rate of , diagnostic accordance rate and resistance were computed on data from the surveillance programs. Chi-square test was used to compare the rates and unconditional logistic regression was used to analyze the related factors of infection. Both the reported incidence rate on bacillary dysentery and detection rate of in diarrhea patients showed significantly decreasing trend, from 2008 to 2017. The accordance rate of bacillary dysentery was only 7.80% (111/1 423). was the most frequently isolated strain (73.95%, 159/215) followed by . Results from the multivariate logistic regression of positive rate revealed that among those patients who were routine test of stool positive . routine test of stool positive (=1.863, 95: 1.402-2.475), onset from July to October . other months'time (=7.271, 95: 4.514-11.709) temperature ≥38 ℃ temperature <38 ℃(=4.516, 95: 3.369-6.053) and age from 6 to 59 years old . other ages (=1.617, 95: 1.085-2.410), presenting higher positive detection rates of from the stool tests. The resistant rates on ampicillin and nalidixic acid were 97.57% (201/206) and 94.90% (186/196), both higher than on other antibiotics. The resistant rates on ciprofloxacin (16.33%, 32/196), ofloxacin (9.57%, 11/115) and on amoxilin (15.05%, 31/206) were relatively low. The resistant rate appeared higher on than on . The proportion of strains with resistance on 3 more drugs, was 30.00%(21/70). The diagnostic accordance rate of bacillary dysentery in Beijing was low, with severe resistance of . Our findings suggested that clinicians should take multiple factors into account in their practices about epidemiological history, clinical symptom and testing results for diarrhea patients.
