Abstract:
Objective To investigate the infection status and epidemiological characteristics of Campylobacter jejuni in diarrhea cases in Jiangsu. Methods Stool specimens of diarrhea cases in Jiangsu Campylobacter jejuni surveillance program were collected in 2020. Campylobacter jejuni was isolated and cultured by the double-well filtration membrane method, and the isolated strains were identified using a fully automated biochemical identification system. Results The positive rate of Campylobacter jejuni in diarrhea cases was 8.38%, with the highest positive rate of Campylobacter jejuni in the diarrhea group of 4-17 years old (27.59%), and the lowest positive rate in the group of 0-3 years old (4.05%). In terms of seasonal distribution, the highest positive rate of Campylobacter jejuni was found in summer (June-August) (9.81%). The positive rate of Campylobacter jejuni in blood stool was the highest (7.39%). Vegetables and their products had the highest positive rate among different categories of suspected foods (33.33%). In terms of processing or packaging methods, catering service food had the highest positive rate (17.46%). In addition, school/institutional collective canteens had the highest positive rate (28.57%) among various eating places. The differences in the positive rates of Campylobacter jejuni among different age groups and different categories of suspected food were statistically significant. Conclusion The monitoring of Campylobacter jejuni in adolescent population should be strengthened, and at the same time, the surveillance and management of vegetables and their products, food service foods and school/institutional collective canteens should be further strengthened.
