Assembly and performance of a cholera RDT prototype that detects both and associated bacteriophage as a proxy for pathogen detection.

Cholera rapid diagnostic tests (RDTs) are vulnerable to virulent bacteriophage predation. We hypothesized that an enhanced cholera RDT that detects the common virulent bacteriophage ICP1 might serve as a proxy for pathogen detection. We previously developed a monoclonal antibody (mAb) to the ICP1 major capsid protein.

Genetic and epigenetic analyses of IFN-γ gene proximal promoter region underlying positive correlation between persistently high anti-SARS-CoV-2 IgG and IFN-γ among COVID-19 vaccinated Bangladeshi adults.

IFN-γ is an immunological modulator influencing IgG isotype and concentration, which present a correlate of protection to evaluate vaccine efficacy. As transiently expressed, stable genetic and epigenetic signatures of the cytokine's expression may exist. This study investigates correlation between plasma IFN-γ and anti-SARS-CoV-2 IgG levels, seeking genetic polymorphisms and epigenetic variations within the IFN-γ gene proximal promoter.

Most frequently harboured missense variants of hACE2 across different populations exhibit varying patterns of binding interaction with spike glycoproteins of emerging SARS-CoV-2 of different lineages.

Since the emergence of SARS-CoV-2 at Wuhan in the Hubei province of China in 2019, the virus has accumulated various mutations, giving rise to many variants. According to the combinations of mutations acquired, these variants are classified into lineages and greatly differ in infectivity and transmissibility. In 2021 alone, a variant of interest (VoI) Mu (B.
