African swine fever (ASF) is a contagious viral disease of wild and domestic pigs that is present in many parts of Africa, Asia and Europe, including Sardinia (Italy). Deletions in the EP402R and B602L genes have been found in almost all ASF virus (ASFV) strains circulating in Sardinia from 1990 onwards, and modern Sardinian strains (isolated after 1990) might have acquired some selective advantage compared to historical ones (isolated before 1990). Here, we analysed the host cell responses of wild boars and domestic pigs upon infection with virus variants. Higher intracellular levels of the late protein p72 were detected after infection with the modern strain 22653/14 compared to the historical strain Nu81.2, although both isolates grew at the same rate in both monocytes and monocyte-derived macrophages. Higher cytokine levels in the supernatants of ASFV-infected pig monocytes compared to pig macrophages and wild-boar cells were detected, with no differences between isolates.
