Immunohistochemical Expression of Keratins in Normal Ovine Skin and in Chronic Dermatitis due to Sarcoptes scabiei.

Hyperproliferation of epidermal keratinocytes is a major histopathological feature of chronic Sarcoptes scabiei dermatitis. We investigated the immunohistochemical expression of several keratins in scabietic dermatitis in sheep and in the skin of healthy sheep, using a panel of commercially available anti-human antibodies for keratins. Keratins AE1/AE3 and 34BE12 were expressed in all epithelial structures in healthy skin.

West Nile virus state of the art report of MALWEST Project.

During the last three years Greece is experiencing the emergence of West Nile virus (WNV) epidemics. Within this framework, an integrated surveillance and control programme (MALWEST project) with thirteen associate partners was launched aiming to investigate the disease and suggest appropriate interventions. One out of seven work packages of the project is dedicated to the State of the Art report for WNV.

European brown hare syndrome in wild European brown hares from Greece.

From 1999 to mid-2003, 97 European brown hares (Lepus europaeus) found dead throughout Greece were examined by necropsy, histopathology, and reverse-transcription polymerase chain reaction (RT-PCR) for the presence of European brown hare syndrome (EBHS) and EBHS virus (EBHSV), respectively. Hare losses were sporadic, starting in the cold season and lasting for many months (December to May). The most prominent gross lesions were observed in the liver and included swelling and discoloration; congestion and hemorrhages were present mainly in lungs and tracheal mucosa.
