Like other lincosamides, pirlimycin acts by binding to the 50S ribosomal subunit of susceptible bacterial RNA, thus interfering with bacterial protein synthesis. It is primarily active against grampositive bacteria, including a variety of species of staphylococcus ( _S. aureus, S. epidermidis, S. chromogenes, S. hyicus, S. xylosus_ ), streptococcus ( _S. agalactiae, S. dysgalactiae, S. uberis, S. bovis_ ) and _Enterococcus faecalis_ .
Pirlimycin mastitis tubes are indicated for the treatment of clinical and subclinical mastitis caused by susceptible organisms in lactating dairy cattle.
