There are literally thousands. Some help us digest our food. Some process our food so that it is not toxic for us to even eat. Some process our foods to increase / add flavor. Some process our wastes. Some are food sources for larger organisms... starting a food chain with us at the top. They become problems when they are concentrated too much, or are concentrated in the wrong places. In general, anaerobic bacteria are only good for processing wastes, and are otherwise very bad.

They are normally not harmful to us and their presence makes it difficult if not impossible for other bacteria to survive on/in us. Some of the normal flora even "give something in return", e.g. E. coli in the gastrointestinal tract metabolize complex carbohydrates (polysaccharides) like cellulosa into smaller saccharides that we can absorb. Cellulosa is found for instance in salad.
