TL;DR: Loss or deficiency of OMPs, coupled with ESBL and/or AmpC production, plays an important role in conferring carbapenem resistance in K. pneumoniae.
Journal ArticleDOI
High prevalence of extended-spectrum and plasmidic AmpC beta-lactamase-producing Escherichia coli from poultry in Tunisia

TL;DR: Healthy chickens constitute an important reservoir of ESBL- and pAmpC-BL-producing E. coli isolates that potentially could be transmitted to humans via the food chain or by direct contact.
Journal ArticleDOI
Prevalence and characterization of plasmid-mediated quinolone resistance genes in extended-spectrum β-lactamase-producing Enterobacteriaceae in a Tunisian hospital.
TL;DR: The objective of the study was to assess the prevalence of plasmid-mediated quinolone resistance (PMQR) genes in a collection of 120 extended-spectrum β-lactamases-producing enterobacteria and to characterize them.
Journal ArticleDOI
Emergence of plasmid-mediated colistin-resistance in CMY-2-producing Escherichia coli of lineage ST2197 in a Tunisian poultry farm.
Elaa Maamar,Carla Andrea Alonso,Zaineb Hamzaoui,Nouha Dakhli,Mohamed Salah Abbassi,Sana Ferjani,Mabrouka Saidani,Ilhem Boutiba-Ben Boubaker,Carmen Torres +8 more
TL;DR: The analysis of the two mcr-1-positive strains and their transconjugants by PCR-based replicon typing and S1-PFGE, demonstrated that mCr-1 gene is linked to an IncP plasmid (~242 kb), and blaCMY-2 to an INCI1 plasmids (97 kb).
Journal ArticleDOI
An Outbreak of NDM-1-Producing Klebsiella pneumoniae, Associated with OmpK35 and OmpK36 Porin Loss in Tunisia
Zaineb Hamzaoui,Zaineb Hamzaoui,Alain A. Ocampo-Sosa,Elaa Maamar,Marta Fernandez Martinez,Sana Ferjani,Sana Ferjani,Samia Hammami,Samia Hammami,Sarra Harbaoui,Nathalie Genel,Guillaume Arlet,Mabrouka Saidani,Amine Slim,Ilhem Boutiba-Ben Boubaker,Luis Martínez-Martínez +15 more
TL;DR: This study describes an outbreak of NDM-1-producing K. pneumoniae strains, isolated from a Tunisian hospital, caused by two clones belonging to ST147 and ST307; and highlights the role of OMPs loss, in combination with β-lactamase expression, in conferring high carbapenem resistance.
