Efficacy of Different Dosage Levels and Routes of Inoculation of Tilmicosin in a Natural Outbreak of Infectious Bovine Keratoconjunctivitis

Abstract

Infectious bovine keratoconjunctivitis (IBK) is a transmissible disease of cattle, affecting beef and dairy herds worldwide. Although several factors can be involved in its pathogenesis, Moraxella bovis, a gram negative bacterium, can be considered the etiological agent. Since the disease can produce considerable economic loss in affected herds, several preventive and therapeutic tools are utilized to control it. Current vaccines are not totally effective to prevent the disease, so once an outbreak is detected, administration of antibiotics is indicated in order to avoid spread of infection within the herd and to obtain a more rapid cure of affected animals.

The goal of this work was to test the efficacy of tilmicosin in a natural outbreak of IBK.
