Antibiotics, also known as antibacterials, are types of medications that destroy or slow down the growth of bacteria. The Greek word antimeans "against", and the Greek word biosmeans "life" (bacteria are life forms).
Antibioticsare used to treat infections caused by bacteria. Bacteria are microscopic organisms, some of which may cause illness. The word bacteria is the plural of bacterium.
Such illnesses as syphilis, tuberculosis, salmonella, and some forms of meningitis are caused by bacteria. Some bacteria are harmless, while others are good for us.
Before bacteria can multiply and cause symptoms, the body's immune system can usually destroy them. We have special white blood cells that attack harmful bacteria. Even if symptoms do occur, our immune system can usually cope and fight off the infection. There are occasions, however, when it is all too much and some help is needed.....from antibiotics.
The first antibiotic was penicillin. Such penicillin-related antibiotics as ampicillin, amoxicillin and benzylpenicilllin are widely used today to treat a variety of infections - these antibiotics have been around for a long time. There are several different types of modern antibiotics and they are only available with a doctor's prescription in industrialized countries.

Do antibiotics cause bacteria to become resistant?
Yes, over use of antibiotics can cause bacteria to become resistant.
What are bacteria diseases immune to antibiotics?
Some bacteria have become resistant to antibiotics due to overuse or misuse of these medications. Examples of antibiotic-resistant bacteria include Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococci (VRE), and Extended-spectrum beta-lactamase (ESBL) producing bacteria. These resistant bacteria can cause infections that are more difficult to treat and may require alternative antibiotics.
How can the overuse of antibiotics lead to antibiotic resistance in bacteria?
The overuse of antibiotics can lead to antibiotic resistance in bacteria because it creates a selective pressure that allows resistant bacteria to survive and multiply while non-resistant ones are eliminated. This can happen when bacteria are repeatedly exposed to antibiotics, leading them to develop genetic mutations that make them resistant to the effects of the medication. Over time, these resistant bacteria can spread and become more common, making the antibiotics less effective.
What is a word meaning a bacteria has adapted to antibiotics?
Resistant or resistance is when a bacteria has adapted to an antibiotic.
are Antibiotics are useful for limiting the growth of most pathogenic bacteria?
no, many bacteria have become resistant due to improper use of antibiotics.
What is an mrsa?
mrsa means multiple resistant staphylococus aureus. Is a bacteria which is resistant to several antibiotics
How does resistance develop in bacteria?
Bacteria, like all organisms, have phenotypic variations. Some bacteria are resistant to antibacterial drugs and survive the onslaught of these drugs. They then go on to have progeny ( by fission ) that they confer this resistance on so that you have a new population of resistant bacteria.
What is antibiotic resistant bacteria?
Also known as "superbugs", antibiotic resistant bacteria have evolved to a point that our usual antibiotics won't kill them. VRE and MRSA are common forms of antibiotic resistant bacteria.
What is the given name to the bacteria that doesn't respond to antibiotics?
If a microbe is not affected by antibiotics, it is said to be resistant to the antibiotic.
Why has there been a large increase of antibiotic resistant strains of bacteria?
Overuse of traditional antibiotics has caused a selection of those bacteria that are resistant to the antibiotic.
Does bacteria exhibit genetic diversity within bacterial species?
Yes. This is why bacteria are becoming resistant to antibiotics.
How do antibiotic resistant bacteria come about?
This term is misleading. The antibiotic "selects" bacteria that are not affected by it. If a person will grow bacteria on a petri dish and add an antibiotic to it, some bacteria may live and grow. This is actually a form of natural selection. The ones that will grow are resistance to the antibiotic. They have some way of not being affected. If a person takes a colony from the plate that has this resistance and grows it on another plate and add the antibiotic, all on the plate will be resistant.
