The vast majority of bacteria are harmless to us humans, and a great number of them are actually beneficial to us. There are, however, a smaller number that are actually harmful. Most of these cause contagious diseases, while some of the more virulent are infectious.

A few like tuberculosis, syphilis, and chlamydia, are infectious, which means that they are spread by intimate contact. It is not so much the type of bacteria that makes it infectious, but rather the transmission route. For a pathogen to be infectious it is spread through contact with body fluids, in particular blood, semen, vaginal secretion, breast milk, and sometimes saliva.
