Pristinamycin, synthesized by Streptomyces pristinaespiralis, is an orally administered antibiotic resembling streptogramin, comprising two distinct components: Pristinamycin I (PI) and Pristinamycin II (PII) . This compound exhibits a high efficacy against various antibiotic-resistant pathogens, especially Gram-positive bacteria such as Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant S. aureus (VRSA), and Enterococcus faecium (VREF) [1].
