A 24-year-old male develops multiple vesiculobullous lesions following treatment for which infection?

The development of multiple vesiculobullous lesions in response to treatment is indicative of a hypersensitivity reaction that can occur after antibiotic therapy, particularly with certain drugs. Mycoplasma pneumoniae infections have been associated with a phenomenon called "erythema multiforme," which can manifest as vesiculobullous eruptions. Antimicrobial treatments, such as those involving beta-lactams or macrolides, can sometimes trigger such reactions in predisposed individuals.

In this context, the lesions are likely a result of the body's immune response to Mycoplasma pneumoniae or a related drug reaction rather than directly caused by the organism itself. Other infections listed do not typically provoke such skin reactions after treatment. For instance, Streptococcus pneumoniae, Escherichia coli, and Neisseria gonorrhoeae infections do not have this specific association with vesiculobullous lesions following treatment, making Mycoplasma pneumoniae the most plausible answer regarding the clinical presentation described.
