Novel synthetic nucleotides of notifiable dengue (1-4), Japanese encephalitis, yellow fever and Zika flaviviruses.

AIM: To produce synthetic nucleotides of notifiable dengue virus (1-4 types), Japanese encephalitis, yellow fever and Zika flaviviruses. These notifiable flaviviruses, particularly dengue and Zika, are problematic mosquito-borne infections in the Philippines, as well as in those countries with tropical and subtropical climates.

METHOD: An algorithmic design formulation of overlap extension - polymerase chain reaction (OE-PCR) was performed to propagate 50-60 oligomer lengths of select notifiable flaviviral RNAs to DNA nucleotides via the two-step process of OE-PCR.

RESULT: Algorithmic OE-PCR design formulation efficiently produced 253-256 bp of notifiable flaviviruses. Comparing the newly designed algorithmic OE-PCR with existing executable programs demonstrated it to be efficient and useful in generating accurate sequences of synthetic flaviviral nucleotides.

CONCLUSION

The efficiently and accurately produced novel synthetic nucleotides of notifiable dengue virus 1-4, Japanese encephalitis, yellow fever and Zika flaviviruses using OE-PCR is useful in understanding the dynamics of flaviviral species and holds potential for the development of synthetic nucleotide-based immunogens.
