U82-U85: Resistance to antimicrobial and antineoplastic drugs

U82: Resistance to betalactam antibiotics

Resistance to betalactam antibiotics is a group of conditions characterized by harmful bacteria's capacity to withstand the effects of certain antibiotics, specifically betalactam antibiotics. These antibiotics, including penicillins and cephalosporins, are commonly used to treat bacterial infections. This resistance typically arises due to genetic changes in bacteria, often transmitted from one to another or induced by the overuse or misuse of these antibiotics. Common symptoms of an infection with resistant bacteria are the same as normal infections and may include fevers, chills, and other signs of inflammation, but these symptoms do not improve with normal antibiotic treatment. Disease progression can be more severe and longer compared to infections with non-resistant bacteria, with an increased chance for complications or even becoming life-threatening. The conditions are categorized by the particular system affected, such as the respiratory or urinary tract.
