U82-U85: Resistance to antimicrobial and antineoplastic drugs

U83: Resistance to other antibiotics

Resistance to other antibiotics refers to a group of conditions where bacteria or other microorganisms have developed the ability to survive or grow in the presence of an antibiotic that would normally kill or inhibit them. This phenomenon occurs due to genetic changes that enable the microorganisms to neutralize the drug's effect, reduce drug concentrations at the site of action, or alter the drug's target site. The transmission of these resistant organisms can occur directly from person to person or indirectly through contaminated surfaces. Common symptoms depend on the site of the infection, which can range from fever, cough, and difficulty breathing if it's a respiratory tract infection, to pain, redness, or swelling if it's a skin or soft tissue infection. Disease progression also varies based on the type of infection and individual's overall health. The resistance affects not only the treatment of infections but also preventive measures like surgical procedures or cancer chemotherapy, making them riskier and potentially less effective.
