Abstract

Azithromycin was shown to specifically inhibit the protein synthesis of Toxoplasma gondii in experimental systems by using free tachyzoites and T. gondii-infected mouse macrophages. RNA synthesis of the parasite was not affected by azithromycin. Inhibition of protein synthesis was also proportional to the relative anti-Toxoplasma activity of three macrolides.
