Seipin accumulates and traps diacylglycerols and triglycerides in its ring-like structure

Zoni, Valeria ; Khaddaj, Rasha ; Lukmantara, Ivan ; Shinoda, Wataru ; Hongyuan, Yang ; Schneiter, Roger ; Vanni, Stefano

In: Proceedings of the National Academy of Sciences, 2021, vol. 118, no. 10, p. e2017205118

Lipid droplets (LDs) are intracellular organelles responsible for lipid storage, and they emerge from the endoplasmic reticulum (ER) upon the accumulation of neutral lipids, mostly triglycerides (TG), between the two leaflets of the ER membrane. LD biogenesis takes place at ER sites that are marked by the protein seipin, which subsequently recruits additional proteins to catalyze LD formation....

Rapid detection of carbapenemase-producing Pseudomonas spp. using the NitroSpeed-Carba NP test

Sadek, Mustafa ; Poirel, Laurent ; Nordmann, Patrice

In: Diagnostic Microbiology and Infectious Disease, 2021, vol. 99, no. 3, p. 115280

The NitroSpeed-Carba NP test was used to rapidly detect and discriminate between the different types of carbapenemases (classes A, B, and D) within 30 minutes among a collection of 202 Pseudomonas sp. strains (mostly Pseudomonas aeruginosa). A total of 99 carbapenemase–(including enzymes exhibiting weak carbapenemase activity such as several Guyana Extended-Spectrum (GES)-ß-lactamases) and...

Efficacy of dual carbapenem treatment in a murine sepsis model of infection due to carbapenemase-producing Acinetobacter baumannii

Cebrero-Cangueiro, T. ; Nordmann, Patrice ; Carretero-Ledesma, M. ; Pachón, J. ; Pachón-Ibáñez, M. E.

In: Journal of Antimicrobial Chemotherapy, 2020, p. dkaa487

Objectives: To evaluate the in vivo efficacy of a dual carbapenem combination containing imipenem plus meropenem against carbapenem-resistant Acinetobacter baumannii producing carbapenemases OXA-23 or OXA-58.Methods: An experimental model of peritonitis using C57BL/6J female mice was developed and the minimum lethal doses were calculated for infections due to OXA-23 or OXA-58 producers of A. ...

Cross-border emergence of clonal lineages of ST38 Escherichia coli producing the OXA-48-like carbapenemase OXA-244 in Germany and Switzerland

Falgenhauer, Linda ; Nordmann, Patrice ; Imirzalioglu, Can ; Yao, Yancheng ; Falgenhauer, Jane ; M.Hauri, Anja ; Heinmüller, Petra ; Chakraborty, Trinad

In: International Journal of Antimicrobial Agents, 2020, vol. 56, no. 6, p. 106157

Background: Carbapenemase-producing Gram-negative bacteria cause infections that are difficult to treat and represent a rising threat to healthcare systems worldwide. This study analysed isolates of Escherichia coli (E. coli), a species associated with nosocomial-acquired and community-acquired infections, from hospitals in Germany and Switzerland exhibiting a slight decrease in...

Cross-border emergence of Escherichia coli producing the carbapenemase NDM-5 in Switzerland and Germany

Chakraborty, Trinad ; Sadek, Mustafa ; Yao, Yancheng ; Imirzalioglu, Can ; Stephan, Roger ; Poirel, Laurent ; Nordmann, Patrice

In: Journal of Clinical Microbiology, 2020, p. -

A series of clinical NDM-5-producing E. coli isolates obtained from two surveillance networks of carbapenem-producing Enterobacterales from 2018-2019, namely Switzerland (NARA) and Germany (SurvCARE), were analyzed. The 33 NDM-5- producing E. coli isolates were highly resistant to β-lactams including the novel ß- lactam/ß-lactamase inhibitor combinations (ceftazidime/avibactam, ...
