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
According to Mayo Clinic, the bacteria that cause staph infections are contagious. Staph bacteria are highly enduring and frequently live on inanimate objects long enough to be transferred to other people. These bacteria are able to withstand extreme temperatures, drying and high salt levels.Full Answer >
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 >
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 >
According to Mayo Clinic, bacterial infections are caused by bacteria and can be treated with antibiotics. Common symptoms of bacterial infections are coughing and sneezing, fever, inflammation, vomiting, diarrhea, fatigue and cramping.Full Answer >
