IMP-1-producing Pseudomonas aeruginosa was first reported in Japan and since then, bacteria with this metallo-β-lactamase have been detected worldwide. Pseudomonas monteilii (part of P. putida group) were considered an environmental pathogen with low virulence potential; however, multidrug-resistant and carbapenem-resistant P. monteilii have emerged. The present study reports the draft sequence of an extensively drug-resistant IMP-16-producing P. monteilii 597/14 isolated from cerebrospinal fluid in 2014. The sequencing data revealed blaIMP-16 as a gene cassette on class 1 integron, In1738 characterized in this study. Furthermore, the resistome of Pm597/14 consisted of 7 resistance genes (aadA1b, strA, strB, aacA4, blaIMP-16, blaOXA-2, sul1) and diverse virulence determinants involved in the adherence, LPS, antiphagocytosis, iron uptake and mercuric resistance. Although different virulence determinants were found in this study, using Galleria mellonella infection model, Pm597/14 did not kill any larvae between 7 days post-infection. P. monteilii isolates have been reported from clinical and environmental sources, carrying different MBL genes showing its potential role as their reservoir.
