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
October 29, 2022By Dr. Darwin Reicks
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.
