Abstract:
This study was aimed at analyzing the Salmonella infection rate,serotype distribution,and drug resistance rate among children with foodborne diseases in Wuhan,to provide evidence for the prevention and control of foodborne diseases in children.We collected pediatric cases of foodborne diseases and fecal specimens in Wuhan from 2017 to 2022,and conducted statistical analysis in SPSS 22.0.A total of 1 180 cases of foodborne diseases in children were monitored,and 281 strains of Salmonella were detected.Salmonella was distributed across 27 serotypes,primarily Salmonella enteritidis(138 strains,ac-counting for 49.11％)and Salmonella typhimurium(37 strains,accounting for 13.17％).The Salmonella-positive cases in-cluded more boys than girls(1.58∶1 ratio),and the age group with the highest detection rate was 7-18 years(34.48％).The proportion of positive patients gradually decreased,and the detection rate gradually increased,with increasing age.Milk and dairy products,fruits and fruit products,and grain and grain products were the main suspected food exposures with high Sal-monella detection rates.The Salmonella detection rate was highest in the third quarter(44.64％),and significant differences were observed in the positivity rates of Salmonella samples across seasons(x2=178.483,P＜0.05).The main clinical mani-festations of children with Salmonella infection were fever(87.19％)and diarrhea(96.44％),primarily watery stool(51.96％).Salmonella showed different degrees of resistance to 14 antibiotics(1.08％-75.99％),primarily ampicillin(75.99％),tetracycline(68.10％),and cefazolin(50.18％).A significant seasonal pattern was observed in the detection of Sal-monella in foodborne diseases among children in Wuhan,and in various suspected food exposures.The serotype composition was polymorphic,and the Salmonella resistance rate was relatively high.Therefore,active monitoring of foodborne diseases and Salmonella resistance surveillance must continue to be strengthened.
