• Bordetella pertussis
• Mycoplasma pneumoniae
• Mixed infections
• Infants

Studying pertussis-like respiratory infections, we report the cases of three infants with evidence of both Bordetella pertussis and Mycoplasma pneumoniae. Bordetella infection was identified by the real-time polymerase chain reaction (RT-PCR) of nasopharyngeal specimens. Neither B. pertussis nor B. parapertussis were recovered on the culture of nasopharyngeal aspirates (NPAs) from any subjects. M. pneumoniae etiology was diagnosed by culture and RT-PCR. The evolution was fatal for all of the subjects. We conclude that, among patients with Bordetella infection, co-infection with another respiratory pathogen is often probable, and these mixed infections might cause a more severe form of illness, sometimes leading to death.
