Traumatic myiasis by Wohlfahrtia magnifica in Italy

Abstract: Seven farms, two in Central Italy and five in Southern Italy, were visited for the presence of larvae-infested wounds. Ninety-six (3%) out of 3129 sheep examined had a traumatic myiasis with a very high percentage of infested animals found only in a farm (10.5%). Wounds were mainly localized on the vulva and prepuce. Infested animals were restless, anxious, and reluctant to graze. None of the 10 goats in one infested flock had wounds, whereas a shepherd dog from another flock presented a wound on the ear. All the larvae and adults reared from them in the laboratory were identified as Wohlfahrtia magnifica (Schiner, 1862) (Diptera, Sarcophagidae). The cases presented here are the first clinical cases of wohlfahrtiosis in sheep and dogs reported in Italy, and indicate that this myiasis is endemic in this country. A wider epidemiological investigation on the prevalence, incidence and seasonality of W. magnifica infestation of Italian W. magnifica population/s would be useful to understand its geographical provenience and the likely risk for its spreading throughout Italy and other non-endemic areas.
