MOLECULAR EPIDEMIOLOGY OF AVIAN POXVIRUS IN THE ORIENTAL TURTLE DOVE (STREPTOPELIA ORIENTALIS) AND THE BITING MIDGE (CULICOIDES ARAKAWAE) IN THE REPUBLIC OF KOREA.

A total of 600 wild birds were analyzed for the causes of mortality in the Republic of Korea (ROK) from 2011 to 2013. Avian poxvirus (APV) infections were identified as the primary cause of mortality in 39% (29/74) Oriental Turtle Doves (Streptopelia orientalis). At necropsy, all 29 S.

Pathology and molecular characterization of recent cases in layer flocks.

Leucocytozoonosis was found in three layer farms in chickens with suspected fatty liver or fatty liver hemorrhagic syndrome in Korea between 2009 and 2011. These layer chicken flocks showed both mortality and decreased egg production for one or two weeks when they were between 59 and 82 weeks old. At the necropsy, the most prominent gross lesions were found in the liver, which was enlarged, had a fragile texture, exhibited yellowish discolorations, and had various hemorrhagic lesions.
