Staphyloccocus aureus is a potentially lethal bacillus that is killed in different ways, including antibiotics, antiseptics and prevention, depending on the environment where it is found. As much as 30 percent of the population carries a particularly virulent strain of staph, MRSA, on the skin, according to About.com.Know More
When staph is on or inside the body, treatment of the infection usually involves a course of antibiotics. This began in the 1950s, according to About.com, with the use of methicillin, a derivative of penicillin, to treat staph infections. Over time, the bacillus evolved resistant strains that are significantly harder to treat with older antibiotics. New antibiotics are constantly being developed, but resistant strains of staph have always arisen in response to drug therapies. This makes it all the more important to prevent transmission entirely.
Preventing the transmission of staph bacteria is largely a matter of treating surfaces and following universal precautions to avoid transmission to uninfected people. When staph is present in food, The U.S. Department of Health and Human Services recommends thorough cooking to kill it. Thorough hand washing with antibacterial soap also is effective in controlling staph.
On surfaces, it is possible to use harsh antiseptics to kill staph. According to the journal "MicrobiologyOpen," copper surfaces are naturally hostile to bacteria, though the reason is not well understood.Learn more about Biology
Staph infections are treated with antibiotics as well as drainage of the infected area, according to Mayo Clinic. Caused by the staphylococcus bacteria, a staph infection can bring about minor skin infections or go deeper into the body, affecting the blood, bones, joints, lungs or heart. Many types of staphylococcus bacteria no longer respond to common antibiotics as of 2014, making treatment of a staph infection more difficult.Full Answer >
Doctors treat Staph infections in pregnant women with antibiotics, according to Sandra Reichstetter, Ph.D., of SteadyHealth.com. They do this because there is a risk of a Staph infection spreading to other parts of the body and because it can put the mother at risk for a more serious infection.Full Answer >
The zone of inhibition is an area around a plate treated with antibiotics where microbes do not grow. The phenomenon is useful when evaluating a microbe's resistance to an antibiotic.Full Answer >
Some of the antibiotics commonly used to treat staph infections include vancomycin, cephalosporins and nafcillin-related antibiotics. Staph infections have become increasingly resistant to traditional antibiotics, and they now often require treatment with stronger medications. This is especially true if the infection is caused by a methicillin-resistant Staphylococcus aurus strain.Full Answer >
