Pirlimycin hydrochloride belongs to the lincosamide class of antimicrobials. Under the trade name Pirsue,[1] it is used in the treatment of mastitis in cattle.[2][3]

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.[4]

Mechanism of action

It is bacteriostatic and acts by inhibiting bacterial protein synthesis via binding with the 50S subunit of the ribosome.[citation needed]
