Drivers of adaptive evolution during chronic SARS-CoV-2 infections Open
In some immunocompromised patients with chronic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, considerable adaptive evolution occurs. Some substitutions found in chronic infections are lineage-defining mutations i…

Molecular Diagnosis of Cat Scratch Disease: a 25-Year Retrospective Comparative Analysis of Various Clinical Specimens and Different PCR Assays Open
Polymerase chain reaction (PCR) for the detection of Bartonella henselae is an important tool for the diagnosis of cat scratch disease (CSD); however, clinical sensitivity varies greatly between studies. The current study shows that the sp…

Drivers of adaptive evolution during chronic SARS-CoV-2 infections Open
In some immunocompromised patients with chronic SARS-CoV-2 infection, dramatic adaptive evolution occurs, with substitutions reminiscent of those in variants of concern (VOCs). Here, we searched for drivers of VOC-like emergence by consoli…

Laboratory Diagnosis of 37 Cases of <i>Bartonella</i> Endocarditis Based on Enzyme Immunoassay and Real-Time PCR Open
Bartonella spp., mostly Bartonella quintana and B. henselae , are a common cause of culture-negative endocarditis. Serology using immunofluorescence assay (IFA) and PCR performed on cardiac tissues are the mainstays of diagnosis.
