 Cutaneous '''Habronemiasis''' is a hypersensitivity reaction to the larvae of the nematode species [[Habronema and Draschia spp.|''Habronema'' and ''Draschia'']].
 The condition is characterised by '''ulcerative, granulomatous''' skin lesions which do not heal.

 Pruritus may be mild to severe.
-In cases of conjunctival habronemiasis there will be gitty plaques on the conjunctival and palpebral borders, which is painful in severe cases leading to epiphora and blephrospasm.

 ===Cytology===
-Cytology of the exudate or skin scrapings frequently reveal larvae but biopsy is recommended because Habronema larvae commonly invade skin lesions with another underlying cause such as infectious granulomas, sarcoids and ulcerative dermatitis.

 ===Biopsy===
 Biopsy will reveal nodular/diffuse granulomatous dermatitis with eosinophilic infiltrates and mast cells. Necrotic foci with multiple nematode larvae and granulation tissue with [[Neutrophils|neutrophils]] along the ulcerated surface are also characteristic.

-Systemic '''glucocorticoids''' decrease the inflammatory response of the the hypersensitivity reaction, oral prednisolone is effective at a dose of 1mg/kg SID or BID for 14days and then tapered.

 Organophosphate pastes and anti-inflammatory pastes can be applied to the wound until it has healed, or the wound should be bandaged to prevent reinfestation.

 ==Description==
-Cutaneous '''Habronemiasis''' is a hypersensitivity reaction to the larvae of the nematode species [[Habronema and Draschia spp.|''Habronema'' and ''Draschia'']]. The adult nematode lives in the stomach of the horse and produces eggs which are then passed in the faeces and hatch into larvae. The larvae are ingested by the [[Musca spp.|house fly]] (''Musca domestica'') or [[Stomoxys calcitrans|stable fly]] (''Stomoxys calcitrans'') in their larval phase, and deposited on equine skin when they feed as adult flies.
