Abstract


Recent incidences of emerging arbovirus (arthropod-borne) disease outbreaks have led to heavy losses globally.Molecular virology offers a range of methods, able to accelerate and improve the diagnosis of arbovirus diseasesbut these rely heavily on the availability of robust PCR-based markers of the causative agents. The great geneticdiversity exhibited by viral genomes makes it difficult to design specific signatures or markers since most methodsstart with a multiple sequence alignment (MSA). This study aimed at exploring the use of recently developedsoftware (PriMux) prototyped on viral pathogens, that designs multiplex compatible degenerate primers withoutneed for an initial MSA. It was used to design family-specific molecular signatures for arboviruses and membersfrom the bunyaviridae and togaviridae virus families were used as models.
