Oestrus ovis is the cause of oestrosis, affecting sheep, goats, and rarely man, invading nasal cavities, frontal and maxillary sinuses, placing its larvae in eyes or snouts, feeding on mucous secretions, to later be eliminated by sneezing together with nasal secretions, reaching the ground where they will acquire the shape of a fly. The main clinical signs are nasal discharge and sneezing, others such as shaking the head, snoring, itching, restlessness, walking in a circle or also called “false tournament” and sometimes fever; For treatment, the subcutaneous application of 1% ivermectin or 5% oral closantel in a dose of 2 ml / 10 kg of weight has been seen, achieving therapeutic effectiveness in sheep.
