Journal ArticleDOI
The Many Faces of Enterococcus spp.-Commensal, Probiotic and Opportunistic Pathogen.
TL;DR: In this paper, the authors discuss both the beneficial properties of these microorganisms and the risk factors related to their evolution towards pathogenicity, which is especially relevant in hospital environments, where enterococcal outbreaks often occur.
Journal ArticleDOI
Coagulase-negative staphylococci (CoNS) as a significant etiological factor of laryngological infections: a review.
Michał Michalik,Alfred Samet,Adrianna Podbielska-Kubera,Vincenzo Savini,Jacek Miedzobrodzki,Maja Kosecka-Strojek +5 more
TL;DR: It is shown that coagulase-negative staphylococci (CoNS) are widely responsible for laryngological diseases and the pathogenicity in terms of virulence determinants, biofilm formation and genetic regulation mechanisms of these bacteria is presented.
Journal ArticleDOI
Emergence of linezolid-resistant Staphylococcus epidermidis in the tertiary children’s hospital in Cracow, Poland

TL;DR: The aim of this study was to genetically characterize 11 LRSE isolates recovered mostly from blood in the University Children’s Hospital in Krakow, Poland, between 2015 and 2017, and found all isolates were multidrug-resistant, including resistance to methicillin, and exhibited so-called PhLOPSA phenotype.
Journal ArticleDOI
Intra-operative biopsy in chronic sinusitis detects pathogenic Escherichia coli that carry fimG/H, fyuA and agn43 genes coding biofilm formation.
Michał Michalik,Alfred Samet,Andrzej Marszałek,Beata Krawczyk,Roman Kotłowski,Alex Nowicki,Tomasz Anyszek,Stella Nowicki,Józef Kur,Bogdan Nowicki +9 more
TL;DR: It is postulate that the simultaneous presence of three genes, each coding biofilm formation, may in part account for the chronicity of E. coli sinusitis.
Journal ArticleDOI
Linezolid-resistant Enterococcus faecium strains isolated from one hospital in Poland -commensals or hospital-adapted pathogens?
TL;DR: The multidimensional analysis has shown the correlation between cfr gene and GI-tract, which suggests horizontal gene transfer inside the gut microbiota and the risk of colonization with linezolid-resistant strains without previously being treated with the antibiotic.
