The Dissemination of a Single Staphylococcusaureus Strain, Spa-t2873, as the Predominant Cause of Bovine Mastitis in Israeli Dairy Farms Open
Staphylococcus aureus is one of the most important pathogens causing intramammary infection (IMI) in dairy herds. The goals of this study were (1) to describe the prevalence of S. aureus in Israeli dairy farms; (2) to characterize the spa-…

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…

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…

Evolution of spike mutations following antibody treatment in two immunocompromised patients with persistent COVID‐19 infection Open
Immunocompromised patients have an increased risk of persistent COVID‐19 disease. We report here the clinical course of two patients with hematologic malignancies hospitalized due to severe acute respiratory syndrome coronavirus 2 (SARS‐Co…

An outbreak of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infections among hospital personnel with high mRNA vaccine uptake Open
Real-world studies have demonstrated impressive effectiveness of the BNT162b2 COVID-19 vaccine in preventing symptomatic and asymptomatic SARS-CoV-2 infection. We describe an outbreak of SARS-CoV-2 infections in a hospital with high vaccin…
