Objective: To investigate the culture and isolation of Bordetella pertussis from hospitalized children diagnosed by Polymerase Chain Reaction (PCR) and the close contacts
and to detect the minimal inhibitory concentration (MIC) of 9 antibiotics
so as to provide reference for rational drug use in clinic. Methods: Nasopharynx swabs specimens were collected for Bordetella pertussis culture from hospitalized children with pertussis diagnosed by PCR and the close contacts in Shenzhen Children’s Hospital from Aug. 2015 to Jun. 2017. MIC of 9 antibiotics such as erythromycin were detected by E-Test for Bordetella pertussis isolates from children. Results: Totally 373 hospitalized children were diagnosed as pertussis
including 223 males (59.79%)
200 cases (53.62%) aged ≤3 months
136 strains of Bordetella pertussis (36.46%) were isolated after culture. Among the 449 close contacts
116 strains of Bordetella pertussis (25.84%) were isolated
mainly from mothers (50.00%
58/116). The sensitivities of Bordetella pertussis to macrolides and sulfamethoxazole-trimethoprim were 47.7% and 100%
respectively. Conclusion: Most hospitalizations with pertussis occurred in infants younger than 3 months. Mothers may be the main source of infants infected by Bordetella pertussis. The resistant Bordetella pertussis isolates to macrolides were common in Shenzhen and no resistance to sulfamethoxazole-trimethoprim isolate was found.
