Nocardia spp. are unique in that they are bacteria that can mimic fungal infections in their presentation but are not susceptible to antifungal agents, making it crucial to correctly identify them to choose the appropriate treatment. They are also resistant to penicillin, which is commonly used for bacterial infections, and they are notably susceptible to sulfonamides, which guides the choice of antibiotics for treatment.
