This group of antibiotics includes methicillin, and the more commonly prescribed penicillin, amoxicillin, and oxacillin among others.MRSA is categorized by the setting in which it is acquired.
The first type, healthcare-acquired MRSA (HA-MRSA), has been recognized since the 1960s.
Strains of staph were identified in patients in hospital and healthcare facilities that were resistant to methicillin (resistance to penicillin had occurred even earlier).
Although staph bacteria do not usually cause infection, they can bring about disease if they penetrate through a break in the skin or through mucous membranes.
Staph bacteria are one of the most common causes of skin infections and sometimes produce relatively minor skin infections such as pimples and boils.
According to a report by the Centers for Disease Control and Prevention (CDC) in the United States in 2005, more 94,000 people developed life-threatening infections caused by MRSA; nearly 19,000 people died during hospital stays related to these MRSA infections.
The majority of MRSA cases, 85 percent, were associated with healthcare facilities, while approximately 14 percent occurred in individuals with no known exposure to healthcare.Contact us if you experience any difficulty logging in.Staphylococcus aureus, often referred to as “staph”, is a common type of bacterium that is found in about 25 to 30 percent of healthy people, primarily on the skin or in the nose.Thirty years ago, MRSA accounted for 2 percent of staph infections.By 2003, 64 percent of staph infections were caused by MRSA.CA-MRSA usually enters the body though a cut or scrape.The first sign of infection is commonly described as resembling a spider bite – a spot on the skin that is red, swollen, and painful. Infrequently, CA-MRSA infection can progress to a more serious disease, such as bloodstream infection or pneumonia. Highly publicized accounts of the deaths of at least three students from CA-MRSA in late 2007 prompted concern among students, parents, and school officials.However, they can cause more serious illnesses such as surgical wound infections, bloodstream infections, bone infections, and pneumonia.In the past few decades, a more dangerous form of staph has emerged.The best defense against MRSA is to maintain good hygiene, including frequent and thorough hand washing, and to avoid the sharing of personal care items.HA-MRSA and CA-MRSA differ at the genetic level and have distinct biologic properties.
