The native aortic valve reduces paravalvular leak in TAVR patients

Frontiers in Physiology, 2022
Background: Paravalvular leak (PVL) is a frequent TAVR complication. Prospective identification of patients who are likely to develop PVL after TAVR would likely lead to improved outcomes.

Contribution of Panton-Valentine leukocidin in community-associated methicillin-resistant Staphylococcus aureus pathogenesis. [PDF]

PLoS ONE, 2008
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) strains typically carry genes encoding Panton-Valentine leukocidin (PVL). We used wild-type parental and isogenic PVL-deletion (Delta pvl) strains of USA300 (LAC and SF8300) and ...

Epidemiological, clinical, outcome and antibiotic susceptibility differences between PVL positive and PVL negative Staphylococcus aureus infections in Western Australia: a case control study [PDF]

, 2015
Background Panton Valentine Leukocidin (PVL) has been associated with invasive Staphylococcus aureus soft tissue and pneumonic infections. Methods From September 2007 to January 2009 at Royal Perth Hospital we tested for the PVL gene in S.

Increase in imported mupirocin-resistant Staphylococcus aureus from the tropics and subtropics: trends in Berlin from 2018 to 2025

New Microbes and New Infections
Background: Mupirocin resistance in Staphylococcus (S.) aureus (Mup-RSA) is emerging and may lead to S. aureus decolonisation failure. Our aim was to assess temporal trends in mupirocin-resistant S. aureus (Mup-RSA) and methicillin-resistant S.

Panton-Valentine leukocidin does play a role in the early stage of Staphylococcus aureus skin infections: a rabbit model. [PDF]

PLoS ONE, 2011
Despite epidemiological data linking necrotizing skin infections with the production of Panton-Valentine leukocidin (PVL), the contribution of this toxin to the virulence of S.

The hepatic regeneration rate (HRR) of the right median lobe after SHAM, PVL and PVL+ISS.

, 2014
Values are means±SD. The HRR of PVL or PVL+ISS was significantly different than the SHAM group at all time points, and the HRR of PVL+ISS was significantly different compared with the PVL group at 72 h and 7 days, but no obvious difference was observed ...

Distinct Bacteriophages Encoding Panton-Valentine Leukocidin (PVL) among International Methicillin-Resistant Staphylococcus aureus Clones Harboring PVL

, 2011
Genetically diverse community-associated methicillin resistant Staphylococcus aureus (CA-MRSA) can harbor a bacteriophage encoding Panton-Valentine leukocidin (PVL) lysogenized into its chromosome (prophage). Six PVL phages (ΦPVL,
