We isolated IMP-19-producing Pseudomonas aeruginosa from 7 patients with nosocomial infections linked to contaminated sinks in France. We showed that blaIMP-19 was located on various class 1 integrons among 8 species of gram-negative bacilli detected in sinks: P. aeruginosa, Achromobacter xylosoxidans, A. aegrifaciens, P. putida, Stenotrophomonas maltophilia, P. mendocina, Comamonas testosteron...

Background: Stenotrophomonas maltophilia (SMA) has emerged as an important pathogen capable of causing opportunistic and nosocomial infection. We performed RNA sequencing (RNA-seq) lung tissues from mice with pulmonary SMA infection over time via aerosolized intratracheal inhalation to investigate transcription profile changes in SMA-infected lungs.

Migratory birds serve as vectors by transmitting antibiotic-resistant bacteria across large distances. Here, we isolated a multidrug-resistant Stenotrophomonas pavanii strain, BWK1, from Mareca penelope feces. Analysis of the draft genome sequence of the isolated strain indicated that BWK1 harbors a class A beta-lactamase, metallo-beta-lactamase, and several multidrug efflux pumps.

We describe a case of empyema with infected ascites caused by Stenotrophomonas maltophilia, which has rarely been reported as pathogenic. The source was determined to a disinfectant solution. The isolate was sensitive to a newer carbapenem-meropenem, and the patient was treated successfully. This case represents a novel dual presentation of a nosocomial infection by the isolate in question.
