Bacteria
Bacteria are a large domain of single-celled, prokaryote microorganisms. Typically a few micrometres in length, bacteria have a wide range of shapes, ranging from spheres to rods and spirals.

What is the triple therapy for helicobacter pylori?
The preferred treatment for helicobacter pylori (H. pylori) infection is triple therapy for two weeks with
- metronidazole (250mg, three times daily)
- a bismuth compound, which prevents degradation of the mucous layer
- bismuth subsalicylate - Pepto-Bismol available in the US (2 tablets, four times a day)
- available as colloidal bismuth subcitrate (De-Nol) elsewhere (120 mg, four times daily)
- either tetracycline (500 mg, four times daily) or amoxicillin (500 mg, three times daily)
Faeces are formed in the large intestines.
Human faeces is the waste product of the human digestive system including bacteria. It varies significantly in appearance, according to the state of the digestive system diet and general health in the digestive system.
Does washing your hands reduce the amount of bacteria on them more than not washing?
Yes, if you wash them correctly with soap/detergent and warm water [see related question below re: how to wash your hands to get rid of germs] or if you use waterless hand sanitizer that is a minimum of 60% alcohol content according to all label directions. Using soap and water and good cleaning processes is more effective than sanitizers, although they are also effective. Studies have shown a reduction by 24 - 77 % of bacteria on hands through good hand washing with soap and water.
The way washing hands with soap and warm water reduces the number of bacteria is threefold:
1. The detergent (most "soap" is actually detergent in today's commercially available products) acts to dissolve and/or remove oils/fats, soil, proteins, and loose skin cells that hold bacteria suspended on or attached to the hands.
2. The friction and warm water physically dislodges and washes away the loosened bacteria down the drain. Warm water is better than cold water because it also helps to loosen the fats and oils better than cold.
3. Drying hands with a clean paper towel removes any residual bacteria present after the sudsing and any that is pooling in the wash water left on your hands after rinsing. It adds more friction to physically remove the bacteria (this is better than using air dryers that dry it in place leaving the residual bacteria behind and better than re-used towels that can put new bacteria back on your clean skin).
What illness can cause the pathogenic bacteria?
No, antibiotics are produced to fight against pathogenic bacteria, Vaccines use dead bacteria to stimulate the immune system to fight against and/or to prevent many diseases. Antibiotics are developed using synthetic basis, or from fungus, like penicilin for example.
What product of bacteria can help to preserve milk?
Lactic acid bacteria can help preserve milk by producing lactic acid through fermentation, which lowers the pH of the milk and inhibits the growth of harmful bacteria. This process is commonly used in making yogurt and other fermented dairy products.
Are ribosomes present in bacteria?
True.
The ribosomes are where polypeptides are assembled from amino acids. Bacterial (prokaryotic) ribosomes are smaller than eukaryotic ones.
These are bacteria that are normally found in your body and on you skin.
Do bacteria reproduce through spores?
Endosposres are intracellular resting cells. With a few exceptions endospore formation is restricted to some large gram positive bacilli. Among cocci and spirila endospores are formed only in few species e.g. Sarcina lutea, S. ureae, Dusulfovibrio desulfuricans. Gramd negative do not form spores or endospores.
A prokaryotic cell, such as a bacterial cell, fits this description. Prokaryotic cells have a single circular DNA strand located in the nucleoid region, a cell wall for structural support and protection, and lack membrane-bound organelles like the Golgi apparatus.
What do bacteria have in common with the cells of other living things?
Bacteria multiplies like other living organisms so they can do the jobs they're supposed to.
Which anaerobic bacteria was used by engelmann in his experiment?
the aerobic bacteria showed him the amount of oxygen produced since aerobic requires oxygen. the more bacteria produced, the more oxygen there had to have been, which means photosynthesis occurred the fastest where there was the greatest amount of bacteria.
What is the relationship between bacteria and plants?
Plants need nitrogen to grow. They are surrounded by nitrogen in the air, but it is not in a form the plants can use. Nitrogen fixing bacteria on the roots of the plant convert (fix) the airborne nitrogen to a form the plants can use to grow.

What chemical produced by some bacteria can limit the growth of other bacteria?
Antibiotics produced by some bacteria, such as penicillin or streptomycin, can limit the growth of other bacteria by disrupting their cell wall synthesis or protein production. These antibiotics can inhibit the growth or kill competing bacteria, giving the producing bacteria a competitive advantage in their environment.
What are the bacteria that live in hot springs called?
The bacteria that live in hot springs are called thermophiles. They are adapted to thrive in high-temperature environments that would be too extreme for most other organisms. Thermophiles are known for their unique heat-resistant enzymes that allow them to function at high temperatures.

What does chroococcidiopsis mean?
Chroococcidiopsis is one of the most primitive cyanobacteria, blue-green algae, known. It is a photosynthetic, coccoidal bacteria and is known for its ability to survive harsh environmental conditions, including both high and low temperatures, ionizing radiation, and high salinity.
The culture in Hawaii has evolved over time as a result of centuries of influence from various indigenous, Asian, and Western cultures. Traditional Hawaiian practices and values, such as hula, lei-making, and aloha spirit, remain strong alongside contemporary influences. Globalization, tourism, and modernization have also impacted Hawaiian culture, leading to a blend of old and new traditions.
Are antiseptics subcutaneously injected drugs used to inhibit bacterial growth?
No, antiseptics are topical agents used on skin surfaces to prevent infection. They are not typically administered by subcutaneous injection. Antiseptics work by inhibiting the growth of microorganisms like bacteria.
