Abstract

Infection of small ruminants with peste des petits ruminants virus (PPRV) and goatpox virus (GTPV) are endemic and can have devastating economic consequences in Asia and Africa. Co-infection with these viruses have recently been reported in goats and sheep in Nigeria. In this study, we evaluated samples from the lips of a red Sokoto goat, and describe co-infection of keratinocytes with PPRV and GTPV using histopathology and transmission electron microscopy. Eosinophilic cytoplasmic inclusion bodies were identified histologically, and ultrastructural analysis revealed numerous large cytoplasmic viral factories containing poxvirus particles and varying sizes of smaller cytoplasmic inclusions composed of PPRV nucleocapsids. These histopathological and ultrastructural findings show concurrent infection with the 2 viruses for the first time as well as the detection of PPRV particles in epithelial cells of the mucocutaneous junction of the lip.
