Description

Spiramycin is a macrolide antibiotic that is clinically used to treat toxoplasmosis and other soft tissue infections. Spiramycin exhibits antibacterial efficacy against Toxoplasma, inhibiting bacterial protein synthesis. In vitro, spiramycin decreases levels of IL-10 and TNF-α, and in vivo, it decreases Toxoplasma-induced brain cysts.
