no. there are not "bronchitis germs" that only cause bronchitis from one person to the next. with that said please know that bronchitis can be cause be a few hundred different viruses (and a few bacteria species) and these germs are capable of being transmitted. a person exposed to a virus that one person to have bronchitis will not necessary cause the same identical illness in another person. it is really where the respiratory viruses takes up residence. this same germ could just as easily cause a cold pink eye sore throat a rash or an ear infection. or nothing at all.
