Lowe, Michelle; Ehlers, Marthie Magdaleen; Ismail, Farzana; Peirano, Gisele; Becker, Piet J.; Pitout, Johann D.D.; Kock, Marleen M. (Frontiers Media, 2018-06-12)Acinetobacter baumannii is an opportunistic pathogen that is increasingly responsible for hospital-acquired infections. The increasing prevalence of carbapenem resistant A. baumannii has left clinicians with limited ...

Carbapenemase-producing Klebsiella pneumoniae : a key pathogen set for global nosocomial dominance Pitout, Johann D.D.; Nordmann, Patrice; Poirel, Laurent (American Society for Microbiology, 2015-10)The management of infections due to Klebsiella pneumoniae has been complicated by the emergence of antimicrobial resistance, especially to the carbapenems. Resistance to the carbapenems in K. pneumoniae involves multiple ...

Peirano, G.; Castellanos, L. Ricardo; Matsumura, Yasufumi; Chaffee, Ryan; Castaneda-Mogollon, Daniel; Pillai, Dylan R.; Pitout, Johann D.D. (American Society for Microbiology, 2024-03)The dissemination of Escherichia coli multidrug-resistant (MDR) STc131 is related to its persistence in the human gastrointestinal tract as efficient gut colonizers. Infection and prevention measures are the cornerstones ...

Matsumura, Yasufumi; Peirano, Gisele; Pitout, Johann D.D. (American Society for Microbiology, 2018-05-24)We report here the complete genome sequence of Escherichia coli J53, which is used as a recipient in conjugation experiments and is a laboratory strain derived from E. coli K-12. This genome sequence will help in the ...

Peirano, Gisele; Chen, Liang; Kreiswirth, Barry N.; Pitout, Johann D.D. (American Society for Microbiology, 2020-09)There is an enormous global public health burden due to antimicrobial-resistant (AMR) Klebsiella pneumoniae high-risk clones. K. pneumoniae ST307 and ST147 are recent additions to the family of successful clones in the ...

Nobrega, Diego; Peirano, Gisele; Pitout, Johann D.D. (Springer, 2022-12)PURPOSE : Extraintestinal pathogenic E. coli (ExPEC) are important pathogens causing community-acquired infections in humans, including bloodstream infections (BSIs), and may also colonize and infect animals. Our aim was ...

Jung, Hyunsul; Pitout, Johann D.D.; Mitton, Barend C.; Strydom, Kathy-Anne; Kingsburgh, Chanel; Coetzee, Jennifer; Ehlers, Marthie Magdaleen; Kock, Marleen M. (Microbiology Society, 2021-06)INTRODUCTION : Colistin is one of the last-resort antibiotics for treating multidrug-resistant (MDR) or extensively drug-resistant (XDR) lactose non-fermenting Gram-negative bacteria such as Pseudomonas aeruginosa and ...
-
Pitout, Johann D.D.; Finn, Thomas J. (Elsevier, 2020-07)The abrupt expansion of Escherichia coli sequence type (ST) 131 is unmatched among Gram negative bacteria. In many ways, ST131 can be considered a real-world model for the complexities involved in the evolution of a multidrug ...
