Autor: Roberto Sierra, Mélanie Roch, Milo Moraz, Julien Prados, Nicolas Vuilleumier, Stéphane Emonet, Diego O. Andrey

Publikováno v: Pathogens, Vol 13, Iss 9, p 730 (2024)

Background. In the context of increasing antimicrobial resistance (AMR), whole-genome sequencing (WGS) of bacteria is considered a highly accurate and comprehensive surveillance method for detecting and tracking the spread of resistant pathogens. Two

Vertical and horizontal dissemination of an IncC plasmid harbouring rmtB 16S rRNA methylase gene, conferring resistance to plazomicin, among invasive ST258 and ST16 KPC-producing Klebsiella pneumoniae

Autor: Mélanie Roch, Roberto Sierra, Kirsty Sands, Willames M.B.S. Martins, Jacques Schrenzel, Timothy R. Walsh, Ana C. Gales, Diego O. Andrey

Publikováno v: Journal of Global Antimicrobial Resistance, Vol 24, Iss , Pp 183-189 (2021)

Objectives: Carbapenem resistance in Klebsiella pneumoniae is a major clinical challenge. Aminoglycosides remain an important asset in the current therapeutic arsenal to treat these infections. We examined aminoglycoside resistance phenotypes and gen

Characterization of Amino Acid Substitution W20S in MgrB Involved in Polymyxin Resistance in Klebsiella pneumoniae

Autor: Mélanie Roch, Willames M. B. S. Martins, Roberto Sierra, Ana C. Gales, Diego O. Andrey

Publikováno v: Microbiology Spectrum, Vol 10, Iss 1 (2022)

ABSTRACT In the major human pathogen Klebsiella pneumoniae, MgrB inactivation by disruptive insertion sequence (IS) elements and mutations leading to early termination are known to play an important role in polymyxin resistance. In this study, we exa

Autor: Roberto Sierra, Luis M Rodríguez-R, Diego Chaves, Andrés Pinzón, Alejandro Grajales, Alejandro Rojas, Gabriel Mutis, Martha Cárdenas, Daniel Burbano, Pedro Jiménez, Adriana Bernal, Silvia Restrepo

Publikováno v: PLoS ONE, Vol 5, Iss 3, p e9847 (2010)

BACKGROUND: Phytophthora infestans (Mont.) de Bary causes late blight of potato and tomato, and has a broad host range within the Solanaceae family. Most studies of the Phytophthora--Solanum pathosystem have focused on gene expression in the host and
