Since amoxicillin is an antibiotic, not a pain reliever, it is important to first determine the cause of the toothache. There are many potential reasons for a tooth to cause pain, including a cracked tooth, gum disease, an abscess, impaction, eruption and muscle spasms. The most common cause of a toothache is a dental cavity. When you... more »
Ear infections are common and you can treat most them at home. In many cases, ear infections arrive from bacteria or viruses like the common cold. Liquid may drain from the ear infected, or there may be pain and irritation. Fortunately, there are safe and effective methods to drain fluid from ear infections, while speeding up the... more »
Staph are bacteria that many people normally carry without becoming ill. Most staph infections are minor and can be treated without antibiotics. Sometimes, however, staph can cause deep skin infections, blood or joint infections or pneumonia. Methicillin-resistant Staphylococcus aureus (MRSA) infections are more difficult to treat... more »
MRSA is a bacterium that's resistant to treatment with commonly used antibiotics. MRSA stands for methicillin-resistant Staphylococcus aureus. Bacteria in the MRSA family are often referred to as staph infections that cause boils and abscess. Understanding what MRSA is, and how to prevent its spread, has major public health... more »
Tattoos were once reserved for the fringe of society, but today it seems like everybody has one. The tattoo has become a means of self-expression, a way to declare one's love for another, and a vehicle for sharing one's beliefs. But as wonderful as tattoos can be, they can also put our health at risk. Tattoo infections are no laughing... more »

Antibiotic resistance is a specific type of drug resistance when a microorganism has the ability of withstanding the effects of antibiotics. Antibiotic resistance evolves via natural selection acting upon random mutation, but it can also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can then transfer the genetic information in a horizontal fashion (between individuals) by plasmid exchange. If a bacterium carries several resistance genes, it is called multiresistant or, informally, a superbug. The term antimicrobial resistance is sometimes used to explicitly encompass organisms other than bacteria.
Antibiotic resistance can also be introduced artificially into a microorganism through transformation protocols. This can aid in implanting artificial genes into the microorganism. If the resistance gene is linked with the gene to be implanted, the antibiotic can be used to kill off organisms that lack the new gene.
Causes
The widespread use of antibiotics both inside and outside of medicine is playing a significant role in the emergence of resistant bacteria. They are often used in animals but also in other industries which at least in the case of agricultural use lead to the spread of resistant strains to human populations. In some countries antibiotics are sold over the counter without a prescription which compounds the problem. In human medicine the major problem of the emergence of resistant bacteria is due to misuse and overuse of antibiotics by doctors as well as patients. Other practices contributing towards resistance include the addition of antibiotics to the feed of livestock."mathew"/> Household use of antibacterials in soaps and other products, although not clearly contributing to resistence, is also discouraged (as not being effective at infection control)., Antibiotic Resistance Questions & Answers, Centers for Disease Control and Prevention, Atlanta, Georgia, USA, accessed Nov read more at » http://en.wikipedia.org/wiki/Antibiotic+resistance
