Habronemiasis aka Summer Sores
1. Caused when Habronema larvae are laid by stable or house flies with a wound, sore or other mucosa.
2. Commonly found around the lips, eyes, sheath and lower limbs.
3. Can become a chronic problem that recurs each year.
4. The body has a large inflammatory reaction creating sulfur granules that are yellow in appearance.
5. Deworming with ivermectin and use of steroids can help but often debridement is needed first to remove those granules.
6. If possible, keep the area covered while healing.
7. Fly control and manure removal can help reduce recurrences.
