[Efficacy of treatments in experimental toxoplasmosis]

Experimental study of the intraocular penetration of six drugs with therapeutic effect on toxoplasma. A direct and an indirect method are used. The penetration of six drugs administered sub-conjunctival, retrobulbar and intramuscular in one shot is measured in the anterior chamber, the vitreous and the retina-choroid of a healthy rabbit eye. The best results are obtained for: spiramycin, trimethoprim-sulfamethoxazole and clindamycin. The therapeutic efficiency of four drugs on infected rabbit eyes with toxoplasma are studied using an indirect method: pyrimethamine and especially doxycycline have a positive effect.
