Abstract:
Objective:to analyze the distribution characteristics of major enteropathogens in infectious diarrhea cases attending the intestinal outpatient clinic of Beijing Traditional Chinese medicine hospital, Capital Medical University.Methods:From 2016 to 2019, 588 fecal samples of patients with infectious diarrhea in Beijing Hospital of traditional Chinese Medicine Affiliated to Capital Medical University were collected for microbial isolation, culture, identification and pathogen gene detection. Using VITEK 2 compact full-automatic microbial identification/drug sensitivity analysis system to identify the bacteria isolated from the culture; using serum agglutination test to classify the pure colonies; using multiple fluorescence quantitative PCR amplification technology to detect the gene amplification of the samples.Results:In 2016-2019, the total physical examination rate of pathogen was 39.796%. The top three pathogen were diarrhea Escherichia coli (21.769%, n=128), Salmonella (5.782%, n=34), Vibrio (4.762%, n=28). The difference of positive rates of different pathogens in four years was statistically significant ( P=0.021), and the peak of incidence was from July to September. The positive rate of norovirus was 5.612% ( n=33), and the highest incidence occurred in May. Conclusion:The pathogen of infectious diarrhea patients in Beijing Hospital of Traditional Chinese Medicine Affiliated to Capital Medical University from April to October 2016-2019 is mainly diarrhea Escherichia coli, and the pathogen type of norovirus is GⅡ genome.
