Effect of roxithromycin or acute toxoplasmosis in mice

Abstract

Roxithromycin effectively treated acute peritoneal murine toxoplasmosis. After five doses, starting 24 h after challenge, the 100 and 50% survival doses were 540 and 336 mg/kg per day, respectively. After 14 doses, starting 3 h after challenge, the 50% survival dose was 360 mg/kg per day. Toxoplasma gondii was recovered from the brain in 59 and 28% of surviving mice treated with 5 and 14 doses, respectively.
