Abstract
Abstract Viral individual genes functions and their role in the interaction with the host cells remain the main area in the study of African swine fever virus (ASFV) biology. The extreme heterogeneity of the ASFV makes it difficult to develop vaccines against this pathogen. In this work, we generated the ASFV deletion mutant virus Volgograd/D(1L-5-6L) with the six genes deletion in multigenic family 110 (MGF110) (1L-5-6L) and studied its characteristics in vitro. The homologous recombination method was used for the deletion in ASFV parental strain Volgograd/14с. A series of six passages was carried out in the COS-1 cell culture using the limiting dilution method. The recombinant strain Volgograd/D(1L-5-6L) MGF110 was selected by the plaque formation method. Performed study of viral replication showed no changes in viral growth kinetics in comparison with the parental strain. The ASFV Volgograd/D(1L-5-6L) MGF110 is a great tool available to test the importance of MGF110 for virus virulence and vaccine development.
期刊介绍：
The Acta Veterinaria is an open access, peer-reviewed scientific journal of the Faculty of Veterinary Medicine, University of Belgrade, Serbia, dedicated to the publication of original research articles, invited review articles, and to limited extent methodology articles and case reports. The journal considers articles on all aspects of veterinary science and medicine, including the diagnosis, prevention and treatment of medical conditions of domestic, companion, farm and wild animals, as well as the biomedical processes that underlie their health.
