What is another word for penicillin-resistant?
Pronunciation: [pˈɛnɪsˌɪlɪnɹɪsˈɪstənt] (IPA) 
Penicillin-resistant refers to bacteria that have developed a resistance to the antibiotic penicillin. Other synonyms for this term include antibiotic-resistant, drug-resistant, and multi-drug resistant. These terms describe bacteria that have evolved to withstand the effects of a particular drug or group of drugs. When bacteria become resistant to antibiotics, it can make infections more difficult to treat and can lead to longer hospital stays, higher costs, and even death. It is important to use antibiotics responsibly and not to overuse them, as this can contribute to the development of resistant bacteria. Researchers continue to study and develop new antibiotics to combat resistance.
