Abstract

One hundred cattle with confirmed natural infections of T. rhodesii were included in 3 studies to evaluate the efficacy of ivermectin for the treatment of eyeworm infection. T. rhodesii were counted in situ in each eye of each animal on day 0 (prior to treatment) and the cattle were paired by the...

Thelazia rhodesi was identified in the conjunctival sacs of 147 (53%) of the 276 cattle examined in 9 farms in Calabria and 162 (39%) of 418 cattle examined on 9 farms in Sicily. Instillation of 1 ml of 0.1% ivermectin into the conjunctival sac of 20 infected animals eliminated the worms within 3...
