Lamp test for asf
Webbisolates have a HAD phenotype. A positive result in the HAD test is definitive for ASF diagnosis. A small number of ‘non-haemadsorbing’ viruses have been isolated, most of which are attenuated or avirulent, but some do produce typical acute ASF. The test is carried out by inoculating blood or tissue suspensions WebbAfrican swine fever (ASF) is one of the most important viral diseases of domestic pigs and wild boar. Apart from endemic cycles in Africa, ASF is now continuously spreading in Europe and Asia. As ASF leads to severe but unspecific clinical signs and high lethality, early pathogen detection is of utm …
