Stenotrophomonas maltophilia induzierte Endophthalmitis
Stenotrophomonas maltophilia, a micro-organism which colonises plastic material was isolated in only 10 known cases of postcataract surgery endophthalmitis (PE) world-wide. We present characteristics, treatment and outcome in 26 cases of PE caused by S. maltophilia contaminated rinsing solution …

Effect of iron and sodium chloride on biofilm development of stenotrophomonas maltophilia
Stenotrophomonas maltophilia is an emerging worldwide, opportunistic respiratory pathogen that is associated with a significant case-fatality ratio in immunocompromised patient populations and has the ability to cause serious infection in cystic fibrosis patients. Populations of S. maltophilia are …

Biofilm and Virulence Regulation of the Cystic Fibrosis Associated Pathogens, Stenotrophomonas maltophilia and Pseudomonas aeruginosa
… to poor prognosis. Two of these pathogens, Stenotrophomonas maltophilia and Pseudomonas aeruginosa, are often found in the lungs of patients with CF and are an increasing medical concerns due to their intrinsic antimicrobial resistance. Both species can readily form biofilms on biotic and …

Caracterización de adultos con aislamiento de Stenotrophomonas maltophilia en una institución de alta complejidad entre 2019 y 2023
Antecedentes: Las infecciones por S. maltophilia presentan desafíos clínicos debido a las limitadas opciones terapéuticas y su asociación con resultados adversos. En nuestro país no existen datos acerca de susceptibilidad antimicrobiana, tratamientos, o desenlaces en pacientes con este …

Microreactor synthesis of labelled polyphenols : a route to antibacterial modes of action in important hospital pathogens
… combination against the bacteria Stenotrophomonas maltophilia, to synthesize theaflavin and deuterium labelled theaflavin in a microreactor and to link the continuous flow process to antimicrobial testing for future mode of action analysis.A 2-step microreactor synthesis using in a …

Microbial degradation of high molecular weight polycyclic aromatic hydrocarbons
… The cultures were identified as strains of Stenotrophomonas maltophilia on the basis of multiple sequence alignment analysis of 16SrRNA gene sequences. Differentiation of the three strains was possible by pulse field gel electrophoresis and DNA:DNA hybridisation methods. The St. maltophilia …

Identification and characterisation of bacterial genes associated with resistance to and/or degradation of environmental pollutants
… from the lead contaminated site, while Stenotrophomonas maltophilia was identified from the PAH contaminated site. Minimum Inhibitory Concentration assays (MICs) were previously performed on Alcaligenes sp. AO22 and Arthrobacter sp. E9 and they were found to be resistant to varying …

Investigation of the prevalence of opportunistic gram negative pathogens in the water supply of a haematology unit, and the application of point-of-use filtration as an intervention.
… opportunistic pathogens Pseudomonas aeruginosa, Stenotrophomonas maltophilia and Acinetobacter baumannii from water outlets of a haematology unit and evaluated Point-Of-Use Filtration (POU-F) as a control measure. In a two-year double cross-over trial, water samples and swabs were taken weekly …

The role of bacterial interspecies communication in polymicrobial infection of the cystic fibrosis lung
… aeruginosa, Burkholderia cenocepacia and Stenotrophomonas maltophilia. These latter bacteria produce signal molecules of the diffusible signal factor (DSF) family, which are cis-2-unsaturated fatty acids. Previous studies showed that DSF from S. maltophilia leads to altered biofilm …

The Microbiome of Cystic Fibrosis Sputum and its Association with Incident Lower Airway Infections
… contributing significantly to disease severity. Stenotrophomonas maltophilia is an emerging pathogen of interest, associated with increased pulmonary exacerbations and lung function decline. This thesis aimed to explore the CF sputum microbiome of persons with CF (pwCF) uninfected with these …

Responses of an Environmental Gram-negative Bacterium to Pollutant Stress
… as Pseudomonas paucimobilis and Pseudomonas maltophilia, were used in this thesis and their stress responsive proteins were surveyed at the physiological level. Additionally, 16S rRNA gene comparison was employed to classify the pseudomonads and related species at the genetic level. In order …
