Figure 6. Risk for Bordetella pertussis reinfection after experimental nasopharyngeal infection of mice. C57Bl/6J mice were inoculated intranasally with 500 CFU of B. pertussis in 5 µL PBS for nasopharyngeal inoculations (blue squares) or 500,000 CFU in 50 µL for the pneumonic inoculations (red squares). The study was conducted twice. Values are the SD of 4 biologic replicates. A) Number of B. pertussis bacteria in respiratory organs on day 7 after pneumonic challenge. B) B. pertussis IgG titers (log scale) in the serum of mice challenged via PNC or NPL inoculation. Green represents naive mice inoculated with PBS. NPL, nasopharyngeal; PBS, phosphate-buffered saline; PNC, pneumonic.
