A mutation responsible for impaired detection by the Xpert SARS-CoV-2 assay independently emerged in different lineages during the SARS-CoV-2 pandemic

BMC Microbiology, 2023
Background COVID-19 diagnosis lies on the detection of SARS-CoV-2 on nasopharyngeal specimens by RT-PCR. The Xpert-Xpress SARS-CoV-2 assay provides results in less than one hour from specimen reception, which makes it suitable for clinical ...

Synthetic O‐Polysaccharide Backbone Units for a Single Antigen Vaccine Against Two Major Non‐Typhoidal Salmonella Serovars

Angewandte Chemie, EarlyView.
A modular strategy was developed to synthesize tri‐, hexa‐, and nona‐saccharides representing repeating units of the conserved O‐polysaccharide backbone of Salmonella. Conjugates of these glycans to bacteriophage Qβ induced strong IgG responses in mice and rabbits. Antibodies elicited recognized native O‐polysaccharides and conferred protection against
