Abstract
BACKGROUND AND AIM: African swine fever (ASF), a globally transmitted viral disease caused by ASF virus (ASFV), can severely damage the global trade economy. Laboratory diagnostic methods, including pathogen and serological detection techniques, are currently used to monitor and control ASF. Because the large double-stranded DNA genome of the mature virus particle is wrapped in a membrane, the stability of ASFV and its genome is maintained in most natural environments. This study aimed to investigate the stability of ASFV under different environmental conditions from both genomic and antibody perspectives, and to provide a theoretical basis for the prevention and elimination of ASFV. MATERIALS AND METHODS: In this study, we used quantitative real-time polymerase chain reaction for pathogen assays and enzyme-linked immunosorbent assay for serological assays to examine the stability of the ASFV genome and antibody, respectively, under different environmental conditions. RESULTS: The stability of the ASFV genome and antibody under high-temperature conditions depended on the treatment time. In the pH test, the ASFV genome and antibody remained stable in both acidic and alkaline environments. Disinfection tests revealed that the ASFV genome and antibody were susceptible to standard disinfection methods. CONCLUSION: Collectively, the results demonstrated that the ASFV genome is highly stable in favorable environments but are also susceptible to standard disinfection methods. This study focuses on the stability of the ASFV genome under different conditions and provides various standard disinfection methods for the prevention and control of ASF.
