Staphylococcus aureus skin colonization is mediated by SasG lectin variation.

Staphylococcus aureus causes the majority of skin and soft tissue infections, but this pathogen only transiently colonizes healthy skin. However, this transient skin exposure enables S. aureus to transition to infection.

causes the majority of skin and soft tissue infections, but this pathogen only transiently colonizes healthy skin. However, this transient skin exposure enables to transition to infection. Initial adhesion of to skin corneocytes is mediated by surface protein G (SasG).

Mechanistic basis of staphylococcal interspecies competition for skin colonization.

Staphylococci, whether beneficial commensals or pathogens, often colonize human skin, potentially leading to competition for the same niche. In this multidisciplinary study we investigate the structure, binding specificity, and mechanism of adhesion of the Aap lectin domain required for skin colonization and compare its characteristics to the lectin domain from the orthologous adhesin SasG. The Aap structure reveals a legume lectin-like fold with atypical architecture, showing specificity for N-acetyllactosamine and sialyllactosamine.

Seroprevalence of SARS-CoV-2 infection in Cincinnati Ohio USA from August to December 2020.

The world is currently in a pandemic of COVID-19 (Coronavirus disease-2019) caused by a novel positive-sense, single-stranded RNA β-coronavirus referred to as SARS-CoV-2. Here we investigated rates of SARS-CoV-2 infection in the greater Cincinnati, Ohio, USA metropolitan area from August 13 to December 8, 2020, just prior to initiation of the national vaccination program. Examination of 9,550 adult blood donor volunteers for serum IgG antibody positivity against the SARS-CoV-2 Spike protein showed an overall prevalence of 8.

Quality of work-life among young medical doctors in Poland.

. Human resource management is the most important function in the management of organizations and significantly affects the quality of work-life (QWL). Recently, the health sector started to be interested in the QWL among doctors.
