A selective culture medium for screening ceftazidime-avibactam resistance in Enterobacterales and Pseudomonas aeruginosa

Sadek, Mustafa ; Poirel, Laurent ; Tinguely, Camille ; Nordmann, Patrice

In: Journal of Clinical Microbiology, 2020, vol. 58, no. 9, p. -

The SuperCAZ/AVI medium was developed for screening ceftazidime-avibactam (CZA) resistance among Gram-negative bacteria (Enterobacterales and Pseudomonas aeruginosa). It was evaluated using 50 CZA-susceptible and 42 CZA- resistant Gram-negative isolates. Its sensitivity and specificity of detection were 100%. Excellent performance of the medium was also observed by testing spiked stools, with ...

Implementation and evaluation of methods for the optimal detection of carbapenem-resistant and colistin-resistant Pseudomonas aeruginosa and Acinetobacter baumannii from stools

Fournier, Claudine ; Poirel, Laurent ; Nordmann, Patrice

In: Diagnostic Microbiology and Infectious Disease, 2020, vol. 98, no. 2, p. 115121

Carbapenem-resistant Acinetobacter baumannii (CRAB) and Pseudomonas aeruginosa (CRPA), as well as polymyxin-resistant A. baumannii (PMR-AB) and P. aeruginosa (PMR-PA), were used to test different enrichment strategies from spiked stools. Three procedures were compared, namely, direct inoculation on selective plates and plating after a 24-h enrichment step in tryptic soy broth with or without ...

Pathogenicity genomic island-associated CrpP-like fluoroquinolone-modifying enzymes among Pseudomonas aeruginosa clinical isolates in Europe

Ortiz de la Rosa, José Manuel ; Nordmann, Patrice ; Poirel, Laurent

In: Antimicrobial Agents and Chemotherapy, 2020, vol. 64, no. 7, p. -

Many transferable quinolone resistance mechanisms have been identified in Gram- negative bacteria. The plasmid-encoded 65-amino-acid-long ciprofloxacin-modifying enzyme CrpP was recently identified in Pseudomonas aeruginosa isolates. We analyzed a collection of 100 clonally unrelated and multidrug-resistant P. aeruginosa clinical isolates, among which 46 were positive for crpP-like genes,...
