A quadruple fluorescence quantitative PCR method for the identification of wild strains of african swine fever and gene-deficient strains.

ABSTRACT:

Background

Originating in Africa, African swine fever (ASF) was introduced to China in 2018. This acute and highly virulent infectious disease affects domestic pigs. The World Organization for Animal Health has listed it as a statutory reportable disease, and China has listed it as a category A infectious disease.

Methods

Primers and probes were designed for four ASFV genes (B646L, EP402R, MGF505-3R, and A137R). The primers/probes were highly conserved compared with the gene sequences of 21 ASFV strains.

Results

After optimization, the calibration curve showed good linearity (R² > 0.99), the minimum concentration of positive plasmids that could be detected was 50 copies/µL, and the minimum viral load detection limit was 10² HAD₅₀/mL. F
