A diabetic individual was diagnosed with cellulitis caused by methicillin-resistant Staphylococcus aureus (MRSA) based on antibiotic susceptibility results. Which of the following antibiotics would NOT be suitable for treatment?

Explanation

MRSA strains are resistant to beta-lactam antibiotics such as imipenem, making it ineffective. In contrast, vancomycin, teicoplanin, linezolid, and daptomycin are all effective treatment options against MRSA infections.
