S. maltophilia is also a risk factor for lung exacerbations in cystic fibrosis patients. Most clinical isolates of S. maltophilia efficiently form biofilms on biotic and abiotic surfaces, making this bacterium resistant to a number of antibiotic treatments and therefore difficult to eliminate. oxidizes glucose and maltose. They are catalase positive, and most are either negative or weakly oxidase positive. This study investigated the isolation frequency, antimicrobial resistance and genotypic relationships of 205 S. maltophilia isolates from 188 patients in a university hospital between 1998 and 2003.
Morphology, Culture Characteristics, and Growth Requirements Cells of S. maltophilia are straight or slightly curved nonsporulating gram-negative bacilli that are 0.5 to 1.5 μm long. Stenotrophomonas maltophilia is a Gram-negative bacterial pathogen of increasing concern to human health. In the present study, phenotypic and genotypic traits of a set of 98 isolates of S. maltophilia obtained from clinical (CF and non-CF patients) and environmental sources were comparatively evaluated. S maltophilia has few pathogenic mechanisms and, for this reason, predominantly results in colonization rather than infection. S. maltophilia attaches to various mammalian cells, and we recently documented that the bacterium encodes a type II secretion system which triggers detachment-induced apoptosis in lung epithelial cells. Stenotrophomonas maltophilia is emerging as one of the most frequently found bacteria in cystic fibrosis (CF) patients. Extracellular DNase activity.

Stenotrophomonas maltophilia is a straight, Gram-negative rod. Jan 26, 2013 - Name: Stenotrophomonas maltophilia Morphology: tuft of polar flagella Gram Stain: Gram-Negative bacilli Growth Characteristics: On sheepblood, colonies appear rough and lavender-green and have an ammonia odor. Despite its limited pathogenicity, Stenotrophomonas maltophilia is an emerging nosocomial pathogen.
Hilmar Wisplinghoff, in Infectious Diseases (Fourth Edition), 2017Stenotrophomonas maltophilia Nature and Taxonomy Stenotrophomonas maltophilia is a ubiquitous environmental bacterium that has also emerged as an important nosocomial pathogen contributing substantially to morbidity and mortality of immunocompromised patients, … Stenotrophomonas maltophilia is a ubiquitous soil bacterium that is increasingly recognized as an emerging nosocomial pathogen. Appearance of Stenotrophomonas maltophilia colonies on various cultivation media after 24 and 48 hours. 16S rRNA gene sequence analysis and DNA–DNA hybridization placed them within the genus Stenotrophomonas and revealed that they were …

Stenotrophomonas maltophilia is an emerging opportunistic and nosocomial pathogen. MacConkey agar - A, E (24 h., 37 °C), F (48 h., 37 °C) Columbia sheep blood agar - C, D …
It is an uncommon pathogen in humans. Three Gram-negative, rod-shaped, non-spore-forming, nitrate-reducing isolates (R-32746, R-32768T and R-32729T) were obtained from soil. : #17061] … This unit includes protocols for the in vitro growth and maintenance of S. maltophilia.
Stenotrophomonas (Xanthomonas) maltophilia is an aerobic gram-negative bacillus that is found in various aquatic environments. These bacteria are motile due to the presence of 4 polar flagella.
