Pirlimycin is an antibiotic which was approved in the US and Europe for the treatment of subclinical mastitis in lactating dairy cattle associated with common mastitis pathogens, mostly Gram-positive bacterias. The drug exerts its action by binding to the 50S ribosomal subunit, therefore hindering the aminoacyl-tRNA binding and inhibiting the peptidyltransferase reaction, which interferes with protein synthesis within the bacteria.

Sample Use Guides

Infuse the contents of one syringe (1 syringe contains pirlimycin hydrochloride equivalent to 50 mg pirlimycin (5 mg/ml)) into each affected quarter by intramammary infusion. Repeat this treatment once, after a 24-hour interval.
Route of Administration: Other
In Vitro Use Guide
Subcultures (0.15 ml) from the clear wells inoculated onto blood agar plates were examined after 24 and 48 h of incubation with pirlimycin at 37C. MIC50 values were 0.5 ug/ml (Staphylococcus aureus, methicillin susceptible); 2 ug/ml (Staphylococcus aureus, methicillin resistant); 1 ug/ml (Staphylococcus sp.); 0.25 ug/ml (Streptococcus pyogenes); 0.5 ug/ml (Streptococcus agalactiae); 0.25 ug/ml (Streptococcus pneumoniae, penicillin susceptible); 0.5 ug/ml (Streptococcus viridans).
