Article Abstract
Detection and sequencing of chikungunya virus (CHIKV) genome was performed using a combination of a modified reverse transcription loop-mediated isothermal amplification (RT-LAMP) method and a MinION sequencer. We developed the protocol for drying all the reagents for the RT-LAMP in a single reaction tube. Using this system, the CHIKV genome was effectively amplified under isothermal conditions, and used as a template for MinION sequencing with a laptop computer. Our in-house RT-LAMP method and MinION sequencing system were also validated with RNAs and serum samples from recent outbreaks of CHIKV patients in Brazil. The obtained sequence data confirmed the CHIKV outbreaks and identified the genotype. In summary, our established inexpensive on-site genome detection and sequencing system is applicable for both diagnosis of CHIKV infected patients and genotyping of the CHIKV virus in future outbreak in remote areas.

Background: Clonotyping of immunoglobulin heavy chain (IGH) gene rearrangements is critical for diagnosis, prognostication, and measurable residual disease monitoring in chronic lymphocytic leukemia (CLL). Although short-read next-generation sequencing (NGS) platforms, such as Illumina MiSeq, are widely used, they face challenges in spanning full VDJ rearrangements. Long-read sequencing via Oxford Nanopore Technologies (ONT) offers a potential alternative using the compact and cost-effective flow cells.

DNA literacy is becoming increasingly essential for navigating healthcare, understanding pandemics, and engaging with biotechnology-yet genomics education remains limited at the secondary level of education. We present a modular, hands-on curriculum designed for high school and early undergraduate students (ages 14-21) that introduces key genomics concepts through an experiment on fermentation, a process that is key to food preservation and medicine. Students follow a complete scientific process: exploring what DNA is and how microbial succession works, analyzing real DNA sequencing data, and writing a formal scientific report.

Unlabelled: Whole genome sequencing (WGS) has emerged as a powerful tool to facilitate the study of existing and emerging infectious diseases. WGS-based genomic surveillance provides information on the genetic diversity and tracks the evolution of important viral pathogens, including respiratory syncytial virus (RSV). Multiplex tiling polymerase chain reaction (PCR) assays have been used to facilitate sequencing of a variety of pathogens in support of genomics-based surveillance initiatives.

Objectives: Selecting and managing suitable seed strains according to standard principles is a critical factor in manufacturing high-quality biological products. In this study, we determined the complete genomes of live animal vaccine bacterial strains used in South Korea and comprehensively analyzed their gene annotations. This detailed genomic analysis provides a robust foundation for identifying and verifying whether manufacturers utilize the same seed strains at the strain level.

There are currently no standardized guidelines for genomic surveillance of One Health antimicrobial resistance (AMR). This project aimed to utilize metagenomics to identify AMR genes present in a companion animal hospital and compare these with phenotypic results from bacterial isolates from clinical specimens from the same veterinary hospital. Samples were collected from sites within a primary care companion animal veterinary hospital in London, UK.
