How does the population of skin bacteria become resistant?
We need you to answer this question!
What is it called when an antibotic is unable to cure a bacterial infection?
When an antibiotic cannot kill a particular strain of bacteria, that bacteria is said to be resistant. The most well-known example of this is MRSA, or methicillin-resistant Staphylococcus aureus. Staphylococcus (or "Staph") is a common bacteria found on the skin of most healthy people. If it gets under the skin, it can cause minor flare-ups like pimples or boils, or more major illnesses like blood infections and pneumonia. Staph is treated by a broad-spectrum antibiotic called methicillin. Some strains of Staph have become resistant to the bacteria, and are then called methicillin-resistant. Most MRSA infections take place in hospitals or health care facilities. These are called health care-associated MRSA, or HA-MRSA. Recently, some other MRSA infections have been occurring in the general population. These are called community-associated MRSA, or CA-MRSA.

What is mercers disease?
Mercers? Im sure what you are asking about is MRSA, it is methicillin-resistant Staphylococcus aureus Staphylococcus aureus, often referred to simply as "staph," are bacteria commonly carried on the skin or in the nose of healthy people. Occasionally, staph can cause an infection; staph bacteria are one of the most common causes of skin infections in the United States. Most of these infections are minor (such as pimples and boils) and most can be treated without antibiotics (also known as antimicrobials or antibacterials). However, staph bacteria can also cause serious infections (such as surgical wound infections and pneumonia). In the past, most serious staph bacteria infections were treated with a certain type of antibiotic related to penicillin. Over the past 50 years, treatment of these infections has become more difficult because staph bacteria have become resistant to various antibiotics, including the commonly used penicillin-related antibiotics (1). These resistant bacteria are called methicillin-resistant Staphylococcus aureus, or MRSA.
Why is MRSA important in surgery?
These bacteria are resistant to most antibiotics and can be found on the skin. When the skin is broken during surgery,or a surgical implant is inserted, bacteria can breed deep inside the body and are almost impossible to eradicate. Absolute cleanliness of operating theatres and surgical instruments is paramount. It is now becoming impossible to adequately sterilise equipment and so disposable instruments will become the norm.

How long should povidone iodine stay on the skin in order to kill bacteria?
Acne is a disorder associated with inflammation of what?
Acne is a skin disorder associated with the inlfammation of the skins' pores. The pores can become blocked and infected by bacteria. This in turn causes the pores to become inflammed and red as the body fights the bacteria. Once the bacteria is dead there is often white or yellow puss left behind under a thin layer of skin.
Asked in Animal Life
How bacteria enter the human body?
Usually bacteria enter the body through a break or cut in the skin. Many are easily destroyed by the simple act of washing; so it is very important to wash your hands often with soap and water when you come in contact with bacteria. Unlike viruses; many can be controlled or destroyed by antibiotics; but it is important not to overuse antibiotics because bacteria can adapt and become resistant. Most people with a healthy immune system can handle most common bacteria because the immune system will produce antibodies which will destroy the bacteria before it gets out of control.
Asked in Health, Microbiology
What effects does bacteria have on the body?
Bacteria is everywhere in and on the body. Most of this bacteria is necessary for keeping the body healthy. When natural bacteria is present, other bacteria which is not natural, has difficulty competing for the resources required to live. Basically, good bacteria prevents bad bacteria from making you sick. When bad bacteria does take over, problems arise: -Eating food which has E. coli on it, due to someone not washing their hands when preparing your food, causes food poisoning. -MRSA which is an antibiotic resistant skin bacteria can cause massive infections in cuts on your skin. There are millions of types of bacteria, some are good for us and some are bad.
Is bacteria harmful and helpful?
Asked in Body Piercing
Can your tongue get infected after getting it pierced?
Any time your skin is pierced, there can be an infection, because bacteria can get in through the hole in the skin, until it heals. Tongues are particularly vulnerable because there is usually a lot of bacteria in the mouth, as a result of the food that passes through, and the saliva, which creates an environment in which bacteria can live. Dry skin is more resistant to infection than wet skin, for this reason. So yes, tongue piercing is risky, and I would strongly recommend against it. You do not need to take that kind of risk.
Asked in Digestive System
How does bacteria reproduce in the digestive system?
Digestive bacteria reproduce by a process called Binary fission, which simply means one cell divided to become two cells, then those two cells become four, four become eight, etc the same way you do. Skin is the first line of defense and it work as physical barrier for all the microbes and particle. Skin has many secretory products which kill the bacteria also.
Asked in Lungs
Can mersa get into your lungs?
"mersa" is actually - MRSA, or Methicillin Resistant Staph Aureous, a staph bacteria that is drug resistant. While Staph is typically a skin bacteria, it can take up residence and thrive (causing an infection) in other areas of your body, including your lungs. I have worked as an RN in both hospitals and home health and have taken care of people with MRSA cause pnemonia.
Is the bacteria MRSA pathogenic or non pathogenic?
MRSA bacteria are pathogenic, this is the name given to a group of bacteria that belong to the Staphylococcus aureus family of bacteria which have grown resistant to methicillin-type antibiotics. MRSA stands for: Methicillin-resistant Staphylococcus aureus. Staphyloccocus aureus bacteria are often carried on people's skin and sometimes in their noses and back of their throats. People carrying the bacteria who are healthy are said to be colonized, but not infected. The bacteria, however, can cause serious infections, such as pneumonia, blood, bone and surgical wound infections, as well as less serious infections such as impetigo, cellulitis and small abscesses or boils under the right conditions.
