| Background: Methyl tert-butyl ether (MTBE) is a pollutant that causes deleterious effects on human and environmental health. Certain microbial cultures have shown the ability to degrade MTBE, suggesting that a novel bacterial species capable of degrading MTBE could be recovered. The goal of this study was to isolate, identify and characterize the members of a bacterial consortium capable of degrading MTBE. Results: The IPN-120526 bacterial consortium was obtained through batch enrichment using MTBE as the sole carbon and energy source. The cultivable fraction of the consortium was identified; of the isolates, only Stenotrophomonas maltophilia IPN-TD and Sphingopyxis sp. IPN-TE were capable of degrading MTBE. To the best of our knowledge, this report is the... |

| Conduziu-se um experimento em casa de vegetação para avaliar o crescimento de mudas de mamoeiro inoculadas com fungos micorrízicos arbusculares (FMAs) e com bactérias diazotróficas, na ausência e presença de fósforo. O delineamento experimental foi o de blocos casualizados, em arranjo fatorial 4 x 3 x 2, sendo os tratamentos compostos por: espécies de fungos micorrízicos arbusculares Glomus clarum, Gigaspora margarita, o inóculo misto Glomus clarum + Gigaspora margarita e o controle sem FMAs; as bactérias diazotróficas Stenotrophomonas maltophilia e Azospirillum sp. e o controle sem bactéria diazotrófica; duas doses de fósforo no solo, 0 e 25 mg dm-3, todos com quatro repetições. Aos 105 dias após a semeadura, as plantas foram coletadas e avaliadas quanto... |

| Abstract Aims We sought to characterize the antibiotic susceptibility of strains of Stenotrophomonas maltophilia isolated from clinical samples, and the role of Stenotrophomonas maltophilia biofilm in antibiotic resistance. Methods Fifty-one clinical Stenotrophomonas maltophilia isolates were obtained from patients with nosocomial infection in the surgical wards and ICUs of six general hospitals in Tianjin, China. In vitro models of Stenotrophomonas maltophilia biofilms were established and confirmed by scanning electron microscopy and fluorescence microscopy with silver staining. The minimal inhibitory concentrations and biofilm inhibitory concentrations of commonly used antibiotics were determined. Results 47 of 51 strains were resistant to three or... |

| Stenotrophomonas maltophilia is a Gram-negative bacillus, which is becoming widely recognized as an important nosocomial pathogen. The main objective of this study was to evaluate the genetic relatedness, by random amplified polymorphic DNA (RAPD) and pulsed-field gel electrophoresis (PFGE) of 86 clinical isolates of S. maltophilia (colonization 22, infection 64) obtained from 79 hospitalized patients, from different geographic regions of São Paulo State. The genotypic analysis performed by RAPD and PFGE was used in 24 isolates for genetic identity confirmation. The results were congruent between the two methods but it was not possible to link genetic profiles with the studied variables, clinical state and geographic area, probably due to the great... |
