Pythium insidiosum is an infectious oomycete affecting dogs that develop the cutaneous or gastrointestinal form of pythiosis with a poor prognosis. If left untreated, pythiosis may be fatal. This organism is not a true fungus because its cell wall and cell membrane lack chitin and ergosterol,...

Conventional antimicrobial therapies are less effective against pythiosis. Therefore, the goal of this study was to characterize the effects of two ozone (O3) presentations on the growth of canine Pythium insidiosum. In Experiment 1, the pathogen was treated with O3 gas at different concentrations...
