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 …

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 …
