Development of an amplicon-based sequencing approach in response to the global emergence of mpox.

The 2022 multicountry mpox outbreak concurrent with the ongoing Coronavirus Disease 2019 (COVID-19) pandemic further highlighted the need for genomic surveillance and rapid pathogen whole-genome sequencing. While metagenomic sequencing approaches have been used to sequence many of the early mpox infections, these methods are resource intensive and require samples with high viral DNA concentrations. Given the atypical clinical presentation of cases associated with the outbreak and uncertainty regarding viral load across both the course of infection and anatomical body sites, there was an urgent need for a more sensitive and broadly applicable sequencing approach.

Lessons from the Murine Models of West Nile Virus Infection.

West Nile virus (WNV), a mosquito-borne, single positive-stranded RNA virus, has been the leading cause of arboviral encephalitis in the U.S. and other parts of the world over the past decade.

Dysregulation of Toll-Like Receptor 7 Compromises Innate and Adaptive T Cell Responses and Host Resistance to an Attenuated West Nile Virus Infection in Old Mice.

Unlabelled: The elderly are known to have enhanced susceptibility to infections and an impaired capacity to respond to vaccination. West Nile virus (WNV), a mosquito-borne flavivirus, has induced severe neurological symptoms, mostly in the elderly population. No vaccines are available for human use.

A review of genetic methods and models for analysis of coronavirus-induced severe pneumonitis.

Coronaviruses (CoVs) have been studied for over 60 years, but have only recently gained notoriety as deadly human pathogens with the emergence of severe respiratory syndrome CoV and Middle East respiratory syndrome virus. The rapid emergence of these viruses has demonstrated the need for good models to study severe CoV respiratory infection and pathogenesis. There are, currently, different methods and models for the study of CoV disease.

Real-time telomerase assay of less-invasively collected esophageal cell samples.

Genomic and proteomic efforts have discovered a complex list of biomarkers that identify human disease, stratify risk of disease within populations, and monitor drug or therapy responses for treatment. Attention is needed to characterize these biomarkers and to develop high-throughput technologies to evaluate their accuracy and precision. Telomerase activity is correlated with tumor progression, indicating cells that express telomerase possess aggressive clinical behavior and that telomerase activity could be a clinically important cancer biomarker.
