Acellular pertussis vaccination enhances B. parapertussis colonization — CIDD

Acellular pertussis vaccination enhances B. parapertussis colonization — CIDD. This study accompanies our earlier post about pertussis vaccination status not a determining factor in preventing illness.

Another point to ponder is the vaccination of dogs with a live virus nasal vaccine for b. pertussis which is called “Kennel Cough” or in humans, tracheobronchitis. The virus in the kennel cough vaccine can colonize, replicate and be shed by the dog for up to 9 months following vaccination. Dogs usually sneeze after receiving the vaccine, and may be shedding the virus and causing infection in some individuals. This infection may be closely similar to the human form of b. pertussis, and should be studied for the possible cause of increased pertussis rates that do not follow the classical whooping cough form of pertussis.
