In vitro activity of β-lactams in combination with avibactam against multidrug-resistant Pseudomonas aeruginosa, Stenotrophomonas maltophilia and Achromobacter xylosoxidans isolates from patients with cystic fibrosis Mathy, Vincent and Grohs, Patrick and Compain, Fabrice,, 67, 1217-1220 (2018), doi = https://doi.org/10.1099/jmm.0.000801, publicationName = Microbiology Society, issn = 0022-2615, abstract= The in vitro activity of anti-pseudomonal β-lactams in combination with avibactam was evaluated against 54 multidrug-resistant non-fermenting Gram-negative bacilli isolated from cystic fibrosis patients. Avibactam increased and/or restored the antibacterial activities of ceftazidime and aztreonam against Pseudomonas aeruginosa and Stenotrophomonas maltophilia, respectively. No β-lactam–avibactam combination was active against Achromobacter xylosoxidans., language=, type=
