The most recent SVA research update reports on-target progress regarding development of reagents and serological assays for Senecavirus A. Rabbit polyclonal antisera produced against whole SVA and individual expressed proteins has been evaluated and is ready to be shared with other researchers and diagnostic laboratories. Good progress has been made on several diagnostic serology prototype tests and selected tests are now being evaluated for sensitivity and specificity. Project deliverables on this specific project will include specific antibody reagents for IHC and fluorescence staining for diagnostic and pathogenesis studies. Also included will be a range of prototype serological assays for improved diagnostic surveillance and prevalence surveys.

SVA clinical cases continue to arise. SVA lesions are clinically indistinguishable from FMD. Each discovery of blisters on the nose or hyperemia of the coronary band, hoof pad or interdigital lesions should first be investigated to ensure FMD is ruled out. Often the first clinical sign observed is lameness. SVA lesions must be reported immediately to SAHO or federal veterinary officials.
