Evaluation of the Presence of ASFV in Wolf Feces Collected from Areas in Poland with ASFV Persistence
African swine fever (ASF), caused by a DNA virus (ASFV) belonging to genus Asfivirus of the Asfarviridae family, is one of the most threatening diseases of suids. During last few years, it has spread among populations of wild boars and pigs in countries of Eastern and Central Europe, causing huge ec...
