A retrospective study of viral skin diseases of cattle, sheep and goats in Plateau State, Nigeria

Abstract

Viral skin diseases namely lumpy skin disease (LSD), bovine papilloma (BP), goat pox (GTP) and contagious ecthyma (CE) have been reported in Plateau State, but our search through literatures did not reveal any documented prevalence rates of these diseases. A retrospective study of LSD, BP, GTP and CE was carried out based on Jos abattoir (2005-2016) and laboratory records of National Veterinary Research Institute, Vom, Nigeria (2010-2016). Based on the Jos Abattoir records, the prevalence rates were as follows LSD: 0.13% and BP 0.5% in Cattle. The prevalence of CE was 4.2%in sheep and 3.6% in goats. While LSD was diagnosed only in 2005, 2008 and 2016, BP was diagnosed every year except 2013, 2015 and 2016. Comparatively, CE was diagnosed in every year and month of the period reviewed. The analysis of records revealed that 11 samples were submitted for lab confirmation from suspected cases of LSD, 45.4% of which were positive by PCR. Additionally, 10 samples submitted for lab confirmation from suspected cases of GTP and 40% of the samples analyzed were positive by PCR. Of the 11 samples submitted for lab confirmation of CE, 36.4% of samples were confirmed to be CE by PCR. The laboratory results validate the Jos abattoir records which confirm that LSD, GTP and CE occur in Plateau State, Nigeria.
