Abstract:
Objective:To explore the application value of bacterial culture and antibody detection of pertussis in children.Methods:A total of 262 children diagnosed with pertussis at the Second Affiliated Hospital and Yuying Children′s Hospital of Wenzhou Medical University from January 2018 to January 2020 were collected as the research objects.Bacterial culture and serum antibody test for pertussis were performed in all cases.According to the gender, age, course of the disease, and whether the children were vaccinated with pertussis vaccine, the patients were divided into different groups and we compared the detection results of different groups.Results:The high incidence age of pertussis was less than 1 year old, mainly less than 6 months old(62.2%). The positive rate of bacterial culture was 82.4%, and the highest positive rate was found in the group of ≤6 months old (94.5%). The positive rate of bacterial culture decreased with the increase of age and course of disease, and the positive rate of children without pertussis vaccination was higher than children with pertussis vaccination( P<0.001). The positive rate of pertussis antibody test was 23.3%.The positive rate of antibody test increased with the increase of age and course of disease and the positive rate of children without pertussis vaccination was lower than children with pertussis vaccination( P<0.001). Conclusion:The high incidence age of pertussis is mainly less than 6 months old.Bacterial culture of pertussis has a good diagnostic value in the early stage of the course, and enzyme linked immunosorbent assay is more helpful in the late stage of the disease.
