- The sustained spread of African swine fever (ASF) virus throughout much of the world has made ASF a global animal health priority, with an increased emphasis on enhancing preparedness to prevent, detect and respond to a potential outbreak of ASF virus (ASFV). In the event of ASFV entry to the North American swine population, enhanced surveillance and diagnostic testing strategies will be critical to facilitate progressive response and eradication of the disease. Compared to individual animal sampling, pen-based oral fluid collection for active surveillance is a non-invasive alternative that is less resource and time-intensive. To evaluate the feasibility of using rope-based oral fluid for early detection of ASFV, four independent animal experiments were conducted in weaned pigs housed in numbers that mimic the industry settings, utilising either highly virulent ASFV Georgia 2007/1 strain or moderately virulent ASFV Malta'78 strain. Pen-based oral fluid and individual oropharyngeal swabs were collected daily and blood samples from each animal were collected every other day. All samples were subsequently tested for ASFV by real-time PCR. ASFV genome was detected in individual blood samples as early as one day post-infection and detected in oral fluids at low-to-moderate levels as early as 3-5 days post-infection in all four independent experiments. These results suggest that pen-based oral fluid samples may be used to supplement the use of traditional samples for rapid detection of ASFV during ASF surveillance.
