The interaction of the Gram-negative bacterium Stenotrophomonas maltophilia with eukaryotes can improve overall plant growth and health, but can also cause opportunistic infections in humans. While the quorum sensing molecule DSF (diffusible signal factor) is responsible for the regulation of phenotypes in pathogenic Stenotrophomonas, up until now, no beneficial effects were reported to be cont...

Amaç:Bu çalışmadaki amacımız, hastanemizde çeşitli kliniklerde tedavi görmekte olan hastaların kan kültürlerinden izole edilen nonfermentatif gram negatif bakterileri tanımlamak, antimikrobiyal direnç profillerini incelemektir. Yöntem:Tıbbi Mikrobiyoloji laboratuvarına Haziran 2016 – 2019 tarihleri arasında gönderilen kültürleri retrospektif olarak değerlendirildi. Kan otomatize sistem ile BacT...

Stenotrophomonas maltophilia is an emerging multi-drug-resistant global opportunistic pathogen of environmental, mainly plant-associated origin. It is also used as a biocontrol or stress protecting agent for crops in sustainable agricultural as well as in bioremediation strategies. In order to establish effective protocols to distinguish harmless from harmful strains, our discussion must take i...

The phylogenetic relationships of all validly described species of the genus Xanthomonas and the type strain of Stenotrophomonas maltophilia were analyzed by sequencing and comparing 16S ribosomal DNAs (rDNAs). The two genera exhibited a mean sequence similarity value of 96.6%, corresponding to differences at 50 nucleotide positions on average. The species of the genus Xanthomonas exhibited rel...

STUDY OBJECTIVES To identify factors predisposing cystic fibrosis (CF) patients to Stenotrophomonas maltophilia infection and to determine whether coinfection with S maltophilia affects the clinical response to therapy with tobramycin solution for inhalation (TSI), 300 mg bid. DESIGN Retrospective review of data collected from two identical, 6-month, randomized, placebo-controlled trials. S...

A Gram-stain negative, rod-shaped, aerobic bacterial strain, BII-R7T, was isolated during a study targeting the culture-dependent microbial diversity occurring in bentonite formations from southern Spain. Comparative 16S rRNA gene sequence analysis showed that BII-R7T represented a member of the genus Stenotrophomonas (class Gammaproteobacteria), and was related most closely to Stenotrophomonas...

Soil samples contaminated with pesticides were collected from agricultural fields in and around Pudukkottai district, TamilNadu. Samples were inoculated into mineral salts medium with Lambda cyhalothrin as the sole source of carbon and incubated for 12 days. Intermittent addition of pesticide was carried out for enrichment of cultures. Bacteria capable of degrading lambda cyhalothrin were isola...

Stenotrophomonas maltophilia contains a novel chromosomally-encoded qnr gene named Smqnr that contributes to low intrinsic resistance to quinolone. We described Smqnr in 13 clinical isolates of S. maltophilia from two Brazilian hospitals, over a 2-year period. The strains were identified by API 20 NE (bioMérieux, France). Susceptibility by microdilution method to trimetroprim/sulfamethoxazole, ...

From March 1997 through November 1997, 8 allogenic bone marrow transplant (BMT) patients developed Stenotrophomonas maltophilia bacteremia on the hematology service at UCLA Medical Center (Los Angeles). Five of these patients had undergone transplantation during the same hospitalization that S. maltophilia bacteremia was detected (case patients). Compared with 7 concurrently hospitalized alloge...
