🚨 Attention horse owners! 🚨
Over the past two weeks, Dr. Berman and Dr. Trawick have identified and treated many cases of habronemiasis, aka summer sores, in our area. These sores are common in the Southeastern U.S., but they also crop up in this region during the summer months. They are caused by the larvae of Habronema nematodes, which are transmitted into wounds or open skin by flies (gross — we know). The larvae can cause a localized inflammatory reaction in the skin, leading to granulation tissue, which we call proud flesh.
In most cases, the wounds and larvae can be treated (potentially through veterinary debridement, depending on the case) without causing major, long-term damage to the health of the equine. However, the healing process and the potential for secondary infection can be a headache for horse owners.
Luckily, there are many ways you can help prevent summer sores:
🩹 Protect small wounds from fly contact. AluShield (silver spray) is not sufficient. Covering wounds with bandages or topical ointments is preferable, as they can form a better barrier against the larvae.
🪰 Get ahead on manure control to curb fly populations.
🔍 Regularly inspect your equine for proud flesh or wounds that are not healing as expected. Topical steroids and systemic oral deworming are potential treatment pathways for managing summer sores, but they should be done under veterinary guidance.
We are hopeful that the fall weather will conclude the fly and summer sore season.
