A total of 18,386 organisms, including 13,224 Enterobacteriaceae, 3536 Pseudomonas aeruginosa, 1254 Acinetobacter spp., and 372Stenotrophomonas maltophilia were collected from Western Europe (WEU; n=10,021), Eastern Europe (EEU; n=4957), and the Asia-Pacific region (APAC; n=3408 [1052 from China]) in 2013-2014 as part of the SENTRY Antimicrobial Surveillance Program and tested by a reference br...

Anatomical barriers for antibiotic penetration can pose a particular challenge in the clinical setting. Stenotrophomonas maltophilia (SM) and Pseudomonas aeruginosa (PA) are two pathogens capable of developing multiple drug-resistance (MDR) mechanisms. We report the case of a 56-year-old female patient with a permanent percutaneous transhepatic biliary drainage (PTBD), who was admitted to our h...

A cryptic multidrug resistance (MDR) system in Stenotrophomonas maltophilia, the expression of which is selectable by tetracycline, is described. Tetracycline resistance was the consequence of active efflux of the antibiotic, and it was associated with resistance to quinolones and chloramphenicol, but not to aminoglycosides or beta-lactam antibiotics. MDR is linked to the expression of an outer...

Fipronil is a widely used insecticide in agriculture and can cause potential health hazards to non-target soil invertebrates and nearby aquatic systems. In the present study, a fipronil degrading bacterium was isolated from fipronil contaminated soil, i.e. rhizospheric zone of Zea mays. Morphological, biochemical and molecular characterization of strain indicated that it clearly belongs to Sten...

The microbiota present in Stomoxys calcitrans larvae may assist their survival in contaminated environments through production of inhibitory substances. Bacteriological identification methods, the polymerase chain reaction (PCR) and scanning electron microscopy (SEM) were used to detect a bacterium naturally present in mucus and macerated S. calcitrans larvae. The antifungal activity was determ...

Three strains of Gram-negative bacteria capable of removing geosmin from drinking water were isolated from biologically active carbon and identified to be Chryseobacterium sp., Sinorhizobium sp. and Stenotrophomonas sp. based on physio-biochemistry analysis and 16S rRNA gene sequence analysis. Removal efficiencies of 2 mg/L geosmin in mineral salts medium were 84.0%, 80.2% and 74.4% for Chryseo...

Stenotrophomonas maltophilia is an aerobic Gram-negative bacillus that usually causes infection in immunocompromised patients. We present the case of an immunocompetent patient with a distal necrosis of the second and third fingers of the right hand caused by S. maltophilia infection. The patient underwent antibiotic therapy with trimethoprim/sulphamethoxazole on the basis of the susceptibility...
