Evaluation of the performance of ELISA for ASF-antibodies detection and its potential use in the US swine industry

The objective of this study was to estimate and compare the diagnostic performance of a novel indirect enzyme-linked immunosorbent assay (iELISA) for ASF serum antibodies (iELISA), developed by Innoceleris Ames, IA, USA and produced and commercialized by Tetracore (Rockville, MD, USA), and the VetAlert™ ASFV DNA Test Kit (qPCR, Tetracore) in both serum and oral fluid (OF) samples collected on farms in Vietnam.

An African Swine Fever (ASF) positive cohort study:  Validating various PCR tests and sample types for African Swine Fever Virus (ASFV) detection in boars; and determining the possibility of transmission via artificial insemination

The first study using experimentally ASFV inoculated adult, commercial boars to determine which sample types and PCR procedures were optimum in detecting ASFV in boars and gilts. Additionally, it proved that insemination of ASFV infected semen to naïve gilts resulted in transmission of the virus.
