A serotype-specific and tiled amplicon multiplex PCR method for whole genome sequencing of dengue virus
Dengue fever, a mosquito-borne viral disease of significant public health concern in tropical and subtropical regions, is caused by any of the four serotypes of the dengue virus (DENV1–4). Cutting-edge technologies like next-generation sequencing (NGS) are revolutionizing virology, enabling in-depth exploration of DENV's genetic diversity. Here, we present an optimized workflow for full-genome sequencing of DENV 1–4 utilizing tiled amplicon multiplex PCR and Illumina sequencing. Our assay, sequenced on the Illumina MiSeq platform, demonstrates its ability to recover the full-length dengue genome across various viral abundances in clinical specimens with high-quality base coverage. This high quality underscores its suitability for precise examination of intra-host diversity, enriching our understanding of viral evolution and holding potential for improved diagnostic and intervention strategies in regions facing dengue outbreaks.
期刊介绍:
The Journal of Virological Methods focuses on original, high quality research papers that describe novel and comprehensively tested methods which enhance human, animal, plant, bacterial or environmental virology and prions research and discovery.
The methods may include, but not limited to, the study of:
Viral components and morphology-
Virus isolation, propagation and development of viral vectors-
Viral pathogenesis, oncogenesis, vaccines and antivirals-
Virus replication, host-pathogen interactions and responses-
Virus transmission, prevention, control and treatment-
Viral metagenomics and virome-
Virus ecology, adaption and evolution-
Applied virology such as nanotechnology-
Viral diagnosis with novelty and comprehensive evaluation.
We seek articles, systematic reviews, meta-analyses and laboratory protocols that include comprehensive technical details with statistical confirmations that provide validations against current best practice, international standards or quality assurance programs and which advance knowledge in virology leading to improved medical, veterinary or agricultural practices and management.
