Microscopic organism: Bacteria are microscopic organisms that are all over our world. There are many, many different kinds. Some of them are helpful to us, like the ones that inhabit our digestive tract and help digest our food. Some of them cause deadly diseases. They can be transmitted in a variety of ways. Some of them can be killed by certain antibiotics, but not all.

Are all bacteria bad?

Family Medicine 31 years experience
No: Not all bacteria are bad; many are important some of the body's most basic processes, including digestion. Bacteria is also a necessary in the formation of certain foods such as cheese. Lastly, we need the normal flora bacteria to compete against the "bad" bacteria in our body, preventing the bad bacteria from overtaking our body.

What are coccoid bacteria?

Dr. Peter Sadow
Pathology 17 years experience
Bacteria : Bacteria are single cell organisms that live in synchrony with our bodies and outside of our bodies. They can be both helpful (symbiotic) and harmful (pathologic) depending on context. Cocci or cocciod bacteria are named for their shape (round), but do not refer to a specific organism.
A 53-year-old member asked:

What medicines contain bacteria?

1 doctor answer2 doctors weighed in
Dr. Stephen Scholand
Infectious Disease 23 years experience
None: Medicines do not contain bacteria. Perhaps you're thinking of supplements such as lactobacilli for digestive health? There are vaccines, some of which are 'live' but weakened (attenuated). The oral typhoid vaccine is an example, but that is a vaccine, not a medicine. If you have a more specific question, maybe a doc here on Htap can help you.
