title: Effect of ozone treatment on Eimeria colchici oocysts.
abstract: The effect of ozone on the inhibition of the sporulation of Eimeria colchici oocysts in vitro was examined. Lower sporulation ratios were found to correspond directly to longer ozone exposure time. In pheasants, Phasianus colchicus, orally inoculated with ozone-treated oocysts, lower mortality and lower oocysts per gram of feces were observed as compared with birds given untreated oocysts. Thus, treatment of E. colchici oocysts with ozone alone was observed to partially inhibit the growth and infectivity of the oocysts.
