Other known breeding grounds include damp places such as shower heads, air conditioners, and hot tubs. Studies in Europe have shown that about 50 percent of dental personnel are infected with a strain of the bacteria, while it is seen in only five percent of the general population.16 Normally it is associated with a mild respiratory infection unless the host is weakened.
