what is bacteria

Question

Answer 1

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.

Answer 2

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.

Answer 3

No.: Many bacteria are helpful, including ones that live in our intestines and help the digestive process and keep out more dangerous bacteria. Also, bacteria are largely responsible for decomposing waste in the environment, ultimately returning complex things into elementals that can be used (such as soil nutrients). Bacteria are everywhere, but only a few species are really harmful.

Answer 4

No: Our bodies are full of bacteria and most are note bad at all. Fecal mater has hundreds of thousands of bacteria, all of which serve a purpose. However, even a "good bacteria" in the wrong site can cause problems.

Answer 5

Antibiotics, soap: Antibiotics kill bacteria inside the body, but different ones kill different types of bacteria. Soap or alcohol hand gel kills most of them on the skin, alcohol and high temperatures (oven or flame) kill bacteria on surfaces.

Answer 6

Disinfectants, antiseptics: All disinfectants (used on inanimate object) and most antiseptics (used on humans) when used iin their appropriate way, will kill bacteria. Many, but not all antibiotics kill bacteria (bacteriocidal - penicillin is an example); some classes weaken bacteria, and require our immune system to finish them off. An example of this "bacteriostatic" effect is tetracycline.

Answer 7

See below: Gram negative bacteria are bacteria that do not pick up the gram stain dye when stained by that technique and then examined under the microscope. They include bacilli like e. Coli and pseudomonas and cocci like neisseria and brucella.

Answer 8

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.

Answer 9

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.
