Bacteria
Bacteria is anywhere and everywhere. The only place that does not contain a lot of bacteria are those areas that have been sterilized in laboratory environments and research facilities and occasional hospital environments. So, what do we do about it? Good question. The answer is that we try our best to avoid contact with large amounts of bacteria that may make us sick. The sources that are most likely to make us sick would likely enter through our mouths, through breathing, anus, sexual activity, or through wounds or open cuts.
