Abstract
The role of Achromobacter species in lung disease remains unclear. The aim of this study was to characterize Achromobacter isolated from persons with cystic fibrosis and from other clinical samples. Whole genome sequences from 101 Achromobacter isolates were determined (81 from patients with cystic fibrosis and 20 from other patients) and analysed. Taxonomic analysis showed nine species including two putative novel species. Thirty-five novel sequence types were present. The most active agent was co-trimoxazole followed by imipenem, but Minimal Inhibitory Concentrations (MICs) were high. Acquired antibiotic resistance genes were rare. Their presence did not correlate with minimal inhibitory concentrations suggesting that other mechanisms are involved. Genes for proposed virulence factors were present in only some isolates. Two putative novel species were identified. The putative virulence properties of Achromobacter involved in infections are variable. Despite the high MICs, acquired resistance genes are uncommon.
