The highest percentage of infection was seen in November(50%), (30%) in February, and the lowest in March (20%). The main fungalspecies that isolated was Trichophyton verrucosum. A single subcutaneousinjection of ivermectin at a dose of 200 microgram/kg. was administered tothe affected animals. Recovery was observed after 10 days after injection,started by scales dropping and appearance of the hair. These findings showthat ivermectin can be used successfully in the treatment of dermatophytosisin bovine induced by immunopotentiation due to the elevation in the totalwhite blood cells ( lymphocytes) after ivermectin injection.
