Journal ArticleDOI
Co-occurrence of extended spectrum β lactamase and MCR-1 encoding genes on plasmids
Marisa Haenni,Laurent Poirel,Nicolas Kieffer,Pierre Châtre,Estelle Saras,Véronique Métayer,Romain Dumoulin,Patrice Nordmann,Jean-Yves Madec +8 more
TL;DR: The dissemination of mcr-1, at least in France, had already occurred more than a decade ago, and it is shown that selection pressure with broadspectrum cephalosporins may select for colistin resistance and vice-versa, further highlighting the likelihood of a pandemic spread of mCr-1.
Journal ArticleDOI
Quorum-sensing-negative (lasR) mutants of Pseudomonas aeruginosa avoid cell lysis and death.
TL;DR: The observation that, in buffered nutrient yeast broth, the wild type and lasR mutants exhibited similar low tendencies to undergo cell lysis and death suggests that alkaline stress may be a critical factor providing a selective survival advantage to lasR Mutants.
Journal ArticleDOI
Distribution and Antimicrobial Resistance of Clinical and Subclinical Mastitis Pathogens in Dairy Cows in Rhône-Alpes, France
Marie-Anne Botrel,Marisa Haenni,Eric Morignat,Philippe Sulpice,Jean-Yves Madec,Didier Calavas +5 more
TL;DR: The risk of transmission of resistant bacteria from milk or milk products to human is very limited, even in case of consumption of raw milk, and the fact that attention must be maintained to avoid any emergence of such resistant bacteria is confirmed.
Journal ArticleDOI
Structure-Function Characterization and Optimization of a Plant-Derived Antibacterial Peptide
Mougli Suarez,Marisa Haenni,Stéphane Canarelli,Florian Fisch,Pierre Chodanowski,Catherine Servis,Olivier Michielin,Ruth Freitag,Philippe Moreillon,Nicolas Mermod +9 more
TL;DR: A synthetic peptide with potent antibacterial activity against specific human pathogens is identified and partly distinct molecular mechanisms for each activity are suggested, including sedimentation and antibacterial activities.
Journal ArticleDOI
Characterization of extended-spectrum beta-lactamase (ESBL)-carrying plasmids and clones of Enterobacteriaceae causing cattle mastitis in France
TL;DR: This study shows a surprisingly low molecular diversity of the strains causing mastitis in France with respect to ESBL genes, plasmids and clones.
