| pubmed-article:10500988 | pubmed:abstractText | Sindbis group viruses can be indirectly identified and classified. Three antigenic subtypes were distinguished by solid-phase enzyme immunoassay (SPEIA): African, West-Asian, and North-European. The negative plaque suppression test is recommended for identification of new Alphavirus strains for detecting species-specific antigenic determinants, and SPEIA for classification by appurtenance to antigenic subtypes. | lld:pubmed |
