Sequence type 101 (ST101) as the predominant carbapenem-non-susceptible Klebsiella pneumoniae clone in an acute general hospital in Italy.
2012
Klebsiella pneumoniae is one of the most common multidrug-resistant (MDR) Gram-negative organisms worldwide, responsible for high morbidity and mortality both in hospitals and alternative healthcare settings. Recently, increasing use of carbapenems has promoted the emergence and dissemination of carbapenem-non-susceptible MDR K. pneumoniae strains. All of the CNSKP strains isolated between January 2009 and December 2011 in the General Hospital of Prato (Prato, Italy) were studied. Our findings indicate that, unlike previously reported by other authors from different regions of Italy, K. pneumoniae producing KPC-2 and belonging to ST101 have been established in the area of Prato, Tuscany, It…

Human Amnion-Derived Mesenchymal Stromal Cells: A New Potential Treatment for Carbapenem-Resistant Enterobacterales in Decompensated Cirrhosis
2022
Background: Spontaneous bacterial peritonitis (SBP) is a severe and often fatal infection in patients with decompensated cirrhosis and ascites. The only cure for SBP is antibiotic therapy, but the emerging problem of bacterial resistance requires novel therapeutic strategies. Human amniotic mesenchymal stromal cells (hA-MSCs) possess immunomodulatory and anti-inflammatory properties that can be harnessed as a therapy in such a context. Methods: An in vitro applications of hA-MSCs in ascitic fluid (AF) of cirrhotic patients, subsequently infected with carbapenem-resistant Enterobacterales, was performed. We evaluated the effects of hA-MSCs on bacterial load, innate immunity factors, and macr…
Caracterización de cepas de Klebsiella pneumoniae resistentes a carbapenems
2022
Introducción: Klebsiella pneumoniae es un importante patógeno humano, tanto en el ambiente hospitalario como en la comunidad. Coloniza las mucosas y la piel de pacientes hospitalizados, causando sobre todo infecciones del tracto respiratorio y del tracto urinario. En personas con comorbilidades se comporta como un patógeno oportunista, especialmente en pacientes inmunocomprometidos. La rápida expansión de la resistencia a antibióticos carbapenémicos en K. pneumoniae, considerados antimicrobianos de última línea, se atribuye a la adquisición de enzimas con capacidad para hidrolizar estos antibióticos. Además, esta diseminación se ve facilitada por la existencia de elementos genéticos móviles…
Double copies of blaKPC-3::Tn4401a on an IncX3 plasmid in Klebsiella pneumoniae successful clone ST512 from Italy
2015
ABSTRACT A carbapenem-resistant sequence type 512 (ST512) Klebsiella pneumoniae carbapenemase 3 (KPC-3)-producing K. pneumoniae strain showing a novel variant plasmid content was isolated in Palermo, Italy, in 2014. ST512 is a worldwide successful clone associated with the spread of bla KPC genes located on the IncFIIk pKpQIL plasmid. In our ST512 strain, the bla KPC-3 gene was unusually located on an IncX3 plasmid, whose complete sequence was determined. Two copies of bla KPC-3 ::Tn 4401a caused by intramolecular transposition events were detected in the plasmid.
