Isolation of African swine fever virus (ASFV) is a critical step towards the identification, titration, characterization, and even modification of the virus. Therefore, it is important to identify a suitable cell line that supports the efficient replication of ASFV for these purposes. This should be achieved even when starting with a low virus load, as in the case of isolating the virus from field samples. This article presents a detailed protocol on the preparation of porcine bone marrow primary (PBMP) cell culture, which has a high sensitivity towards ASFV, resulting in high viral yields with a minimal risk of bacterial contamination.
