Mycoplasma pneumoniae is a type of “atypical” bacteria that commonly causes mild infections of the respiratory system.In fact, pneumonia caused by M. pneumoniae is sometimes referred to as “walking pneumonia” since symptoms tend to be milder than pneumonia caused by other germs. This type of pneumonia is considered atypical due to the fact that the cells causing the infection are resistant to penicillin, the drug that is normally used to treat pneumonia.
