U82: Resistance to betalactam antibiotics
U82.0: Resistance to penicillin
Resistance to penicillin is a medical condition where someone's body, more specifically the bacteria within, becomes able to withstand the effects of the antibiotic penicillin. This happens when bacteria change in a way that reduces the effectiveness of the drug. The change can be a result of genetic mutation or the acquisition of resistance genes from other bacteria. Once the bacteria are resistant, penicillin can no longer kill them or stop their growth, leading to more severe or longer-lasting infections. Symptoms will typically be those of the underlying infection which the penicillin was intended to treat, and may not improve despite medication. The condition poses a significant challenge in treating common bacterial diseases like pneumonia and ear infections.
