African swine fever caused by the African swine fever virus is a severe and acute viral disease that has damaged the world's swine industry with billions of losses. Nowadays almost every country has established strict prevention and control strategy for ASF. However, due to the complexity of the disease and the high requirement of biosecurity in reforming, new strategies still are required for ASF control.

The importance of antibody testing in African swine fever control

In the recent closed Anual Veterinary Diagnostic Conference in Nanjing, Dr. Luis Gimenez Lirola from Iowa State University had a great report on the testing strategies in ASF. prevention and control. 

He mentioned that in acute infection of ASF, PCR positive and antibody-negative results were 66%, PCR positive and antibody-positive results were 34%, PCR negative and antibody-positive results were 0%. In subacute infection of ASF, PCR positive and antibody-negative results were 10%, PCR positive and antibody-positive results were 87%, PCR negative and antibody-positive results were 3%. In chronic infection of ASF, PCR positive and antibody-negative results were 2%, PCR positive and antibody-positive were 31%, while PCR negative and antibody-positive results were 67%.

From the research, we can find that in subacute and chronic infection of ASF, PCR negative results do not rule out ASF infection, antibody testing shall still be considered as an important tool for ASF eradication.
