Beta-lactam antibiotics. Î²-Lactam antibiotics are the most widely used class of drugs for the treatment of bacterial infections and have been prescribed for over 70 years (Crowder, Spencer, & Vila, 2006; Daumann, Schenk, & Gahan, 2014; Page & Badarau, 2008; Phelan et al., 2014). From: Advances in Protein Chemistry and Structural Biology, 2014
Some strains of staph developed resistance to beta-lactam antibiotics. It is estimated that 2 percent of the population now carry a strain of staph that is resistant to beta-lactam antibiotics. Most of the staph infections that now occur in hospitals are caused by MRSA.
