Document Type : Original Articles



This work aimed to study the prevalence of different skin q[fections in equine and the risk factors influencing it during one year from February 2009 to February 2010. Out of 3014 examined equine, 267 (8.86%) were s4ffering from skin diseases. The prevalence rate was dermatophytosis 3.52%, Sweet itch 2.19%, Mange 1.46%, bac­ terial dermatitis 0.36% , cutaneous pythiosis 0.3%, cutaneous habronemiasis 0.27%, vitiligo 0.2%, allergic dermatitis 0.2%, urticaria 0.17%, tick allergy 0.13% and equine warts 0.07%. Dermatophytosis occurred with high incidence rate in Arabian horses al­ though good hygiene and management comparing to drqft horses which showed spo­ radic cases. The disease occurred more commonly in younger ages and infall season. The mycotic cultivation revealed 75 dermatophyte isolates. The most common isolated dermatophyte was T.equinum 53.3%followed by M.canis 29.3% and other dermatoph­ ytes were isolated as M.gypseum 9.3%, T.mentagrophytes 5.3%, T.tonsurans 1.3% and M.audouinii 1.3%. Sweet itch occurred with higher incidence in horses at summer sea­ son and the number of horses q[fected with sweet itch rose with increasing age. Mange was diagnosed mostly in draft horses and donkeys with high incidence in win­ ter. No age difference was observed in the occurrence of mange in equine. Psoroptic mange was the most common cause of mange in equine
