Mechanism of Pseudomonas aeruginosa persistence during treatment with broad-spectrum cephalosporins of lung infections in patients with cystic fibrosis.

abstract：:Stenotrophomonas maltophilia is increasingly being isolated from the respiratory tract of individuals with cystic fibrosis, and, because of its multidrug-resistant nature, the selection of suitable treatment regimens can be problematical. Etest methodology was used to facilitate MIC and antimicrobial combination testi...
