Disinfectants, alcohols and other chemicals were studied for effect against Toxoplasma oocysts. They included Lomasept and Neo Kurehasol, one of orthoes, as useful disinfectants against chicken coccidial oocysts. Two strains of Toxoplasma oocysts isolated from unwanted cats that had spontaneously been infected with the small type of Isospora bigemina were used in this experiment. Sensitization with 1% Neo Kurehasol for 120 minutes, with 1% Lomasept for 10 or 15 minutes, or with 5% Lomasept for 5 minutes inhibited sporulation of unsporulated oocysts completely. No sporulated Toxoplasma oocysts were exterminated by any ordinary disinfectant even after 48-hour sensitization. It was confirmed that sensitization with Neo Kurehasol or peracetic acid for 48 hours, with ethanol for 24 hours, or with methanol for 12 hours was oocysticidal. Oocysts that had been sensitized with Lomasept at a concentration of 1%, 3% or 5% for 3 hours were completely exterminated. An oocysticidal effect was observed after 30-minute sensitization with 10% ammonia water and 1-hour sensitization with ammonium sulfide. It took 4 days for 10% formalin to exterminate Toxoplasma oocysts.
