TL;DR: The present study was conducted from July to August 2018 on milk samples taken at dairy farms in the Northern Province and Kigali District of Rwanda in order to identify Staphylococcus spp.
Journal ArticleDOI
Increased genetic diversity of methicillin-resistant Staphylococcus aureus (MRSA) isolated from companion animals.

TL;DR: Compared to the time period 2004-2013, the results of the present study show not only a higher diversity among the MRSA isolates within the population of Austrian companion animals, but also the introduction of new clones.
Journal ArticleDOI
Within-host evolution of bovine Staphylococcus aureus selects for a SigB-deficient pathotype characterized by reduced virulence but enhanced proteolytic activity and biofilm formation.
Helene Marbach,Katharina Mayer,Claus Vogl,Jean Y. H. Lee,Ian R. Monk,Daniel O. Sordelli,Fernanda R. Buzzola,Monika Ehling-Schulz,Tom Grunert +8 more
TL;DR: This study extends the role of sigma factor SigB in S. aureus pathogenesis to underpin the clinical relevance of staphylococcal SigB-deficient variants which are consistently isolated during human chronic infections.
Journal ArticleDOI
Within-Host Adaptation of Staphylococcus aureus in a Bovine Mastitis Infection Is Associated with Increased Cytotoxicity.
Katharina Mayer,Martin Kucklick,Helene Marbach,Monika Ehling-Schulz,Susanne Engelmann,Tom Grunert +5 more
TL;DR: In this paper, the authors investigated the adaptive processes of S. aureus during chronic, persistent bovine mastitis using a previously isolated isogenic strain pair from a dairy cow with chronic, subclinical mastitis, in which the last variant (host-adapted, Sigma factor SigB-deficient) quickly replaced the initial, dominant variant.
Journal ArticleDOI
Phase Diagram for a Lysyl-Phosphatidylglycerol Analogue in Biomimetic Mixed Monolayers with Phosphatidylglycerol: Insights into the Tunable Properties of Bacterial Membranes.
Christian Wölk,Hala Youssef,Thomas Guttenberg,Helene Marbach,Gema Vizcay-Barrena,Chen Shen,Gerald Brezesinski,Richard D. Harvey +7 more
TL;DR: The surface charge and lipid packing characteristics of synthetic biomimetic mixtures of DPPG and DP3adLPG in Langmuir monolayers are examined using a combination of complementary surface‐probing techniques such as infrared reflection‐absorption spectroscopy and grazing‐incidence x‐ray diffraction.
