==Activity== Pirlimycin is active against Gram-positive bacteria, specifically ''Staphylococcus aureus'' and coagulase negative species of ''Staphylococcus'' and ''Streptococcus''. It has no activity against Gram-negative bacteria.<ref>{{Cite web |url=http://www.usp.org/pdf/EN/veterinary/pirlimycin.pdf |title=USP: Pirlimycin |access-date=2009-06-28 |archive-url=https://web.archive.org/web/20090509031543/http://www.usp.org/pdf/EN/veterinary/pirlimycin.pdf |archive-date=2009-05-09 |url-status=dead }}</ref>

==Mechanism of action== It is bacteriostatic and acts by inhibiting bacterial protein synthesis via binding with the 50S subunit of the ribosome.{{cn|date=January 2023}}
