Tylvalosin
Tylvalosin, a macrolide antibiotic, is active against S. aureus, E. coli, and P. multocidas with MICs of 2, 128, and 128 μg/mL, respectively. Tylvalosin (5 and 10 μg/mL) reduces LPS-induced production of proinflammatory cytokines, prostaglandin E2 (PGE2) and nitric oxide in RAW 264.7 cells. Preparations containing tylvalosin have been used for the treatment and metaphylaxis of enzootic pneumonia caused by M. hyopneumoniae in pigs.
