P. vivax originates from sub-Saharan Africa based on the circulation of its closest genetic relatives ( P. vivax-like) among African great apes. However, the limited number of genetic markers and samples investigated questions the robustness of this hypothesis. Here, we extensively characterized the genomic variations of 447 human P. vivax strains and 19 ape P. vivax-like strains collected worldwide. Phylogenetic relationships between human and ape Plasmodium strains revealed that P. vivax-like, not included within the radiation of P. vivax-like. By investigating various aspects of P. v...

Researchers in the US recently infected a series of human lung and head/neck cancer cell lines with SARS-CoV-2 that expressed varying levels of ACE2 and the TMPRSS2 protease to reassess their role in viral entrance.

Abstract International migrants are at heightened risk for tuberculosis (TB) disease. Intensified incarceration at international borders may compound population-wide TB risk. However, few studies have investigated the contributions of migration, local transmission, or prisons in driving incident TB at international borders. We conducted prospective population-based genomic surveillance in 3 cities along Brazil’s central western border from 2014–2017. Although most isolates (89/132; 67%) fell within genomic transmission clusters, genetically unique isolates disproportionately occurred amon...

Abstract Single-cell whole-genome sequencing (WGS) is critical for characterizing dynamic intercellular changes in DNA. Current sample preparation technologies for single-cell WGS are complex, expensive, and suffer from high amplification bias and errors. Here, we describe Digital-WGS, a sample preparation platform that streamlines high-performance single-cell WGS with automatic processing based on digital microfluidics. Using the method, we provide high single-cell capture efficiency for any amount and types of cells by a wetted hydrodynamic structure. The digital control of droplets in a cl...
