Here is a list of some well-known organisms under the Kingdom Bacteria:

1. Escherichia coli (E. coli): A commonly studied bacterium found in the intestines of humans and animals. It can be harmless but some strains can cause infections.

2. Streptococcus species: A group of bacteria known for causing various infections, including strep throat, pneumonia, and skin infections.

3. Staphylococcus aureus: Commonly found on the skin and mucous membranes, this bacterium can cause skin infections, food poisoning, and more severe infections if it enters the bloodstream.

4. Bacillus subtilis: A Gram-positive bacterium commonly found in soil. It has been used extensively in research and industry due to its ability to produce various enzymes and antimicrobial compounds.

5. Mycobacterium tuberculosis: The bacterium that causes tuberculosis, a potentially serious infectious disease affecting the lungs.

6. Helicobacter pylori: A bacterium that lives in the stomach and is associated with causing gastrointestinal problems like gastritis and peptic ulcers.

7. Chlamydia trachomatis: A sexually transmitted bacterium responsible for causing various genital infections, including chlamydia.

8. Cyanobacteria: Also known as blue-green algae, these photosynthetic bacteria play a vital role in oxygen production and are found in various aquatic environments.

9. Salmonella enterica: Bacteria that can cause food poisoning, resulting in symptoms such as fever, diarrhea, and abdominal pain.

10. Lactobacillus species: These bacteria are commonly found in the gut and ferment milk products. They are frequently used in probiotics.

Please note that this list is not exhaustive, as there are thousands of different bacterial species, and new ones are still being discovered.
