Res. SOUZA VIANA,ELISETH; MARTINO CAMPOS,MARIA EMILENE; REIS PONCE,ADRIANA; CUQUETTO MANTOVANI,HILÁRIO; DANTAS VANETTI,MARIA CRISTINA. The objective of this study was to detect the presence of acyl homoserine lactones (AHLs), signal molecules of the quorum sensing system in biofilm formed by Hafnia alvei strains. It also evaluated the effect of synthetic quorum sensing inhibitors in biofilm formation. AHLs were assayed using well diffusion techniques, thin layer chromatography (TLC) and detection directly in biofilm with biomonitors. The extracts obtained from planktonic and sessile cell of H. alvei induced at least two of three monitor strains evaluated. The presence of AHLs with up to six carbon atoms was confirmed by TLC. Biofilm formation by H. alvei was inhibited by furanone, as demonstrated by 96-well assay of crystal violet in microtitre plates and by scanning electron microscopy....

Marine water was used for the biofilm forming bacterial isolation. A biofilm forming device was made by using PVC pipes with sterile glass slides. Five morphologically different bacteria were isolated from the scrapping of glass slides from the device after a month period of time. The efficiency of EPS production was checked for all the isolates. Using scanning electron microscope (SEM), the morphology of microbial cells and colonies was studied. The maximum EPS was produced by the strain B3, which was analyzed and characterized by thin layer chromatography (TLC) and Fourier transform infrared spectroscopy (FTIR) spectra. B3 EPS displayed a strong absorption band of - OH at 3415.31 cm-1 and COOH at 1631.48 cm-1 showing it to be polysaccharide.

ABSTRACT Novel strategies to combat the ever increasing burden of drug resistance in Mycobacterium tuberculosis (MTB) causing tuberculosis (TB) remains a global concern. The ability of MTB to sense and adapt to restricted iron conditions in the hostile environment is essential for their survival and confers the basis of their success as dreadful pathogen. The striking and clinically relevant virulence trait of MTB is its ability to form biofilms and adhere to the host cells. The present study elucidated the effect of iron deprivation on biofilm formation and cell adherence of Mycobacterium smegmatis, a non-pathogenic surrogate of MTB. Firstly, we showed that iron deprivation leads to enhanced cell sedimentation rate and altered colony morphology depicting...

ABSTRACT Vancomycin-resistant Enterococcus faecium (VREfm) has emerged as an important global nosocomial pathogen, and this trend is associated with the spread of high-risk clones. Here, we determined the genetic and phenotypic features of 93 VREfm isolates that were obtained from patients in 13 hospitals in Vitória, Espírito Santo, Brazil, during 2012-2013. All the isolates were vancomycin-resistant and harbored the vanA gene. Only 6 (6.5%) of the VREfm isolates showed the ability to form biofilm. The 93 isolates analyzed belong to a single pulsed-field gel electrophoresis lineage and presented six subtypes. MLST genotyping showed that all VREfm belonged to ST412 (the high-risk clone, hospital-adapted). The present study describes the dissemination of...

Biofilm production is an important mechanism for bacterial survival and its occurrence together with antimicrobial resistance represents a challenge for clinical management. Here, we evaluated the ability for biofilm production among P. aeruginosa isolates from patients with or without cystic fibrosis (CF) using two distinct media, besides determining the antimicrobial susceptibility profile of these isolates for eight antimicrobial agents. The ability for biofilm production when TSB medium was used was higher than when used CF sputum media (p = 0.0198). However, P. aeruginosa isolates from CF have demonstrated similar performance for biofilm production, independently of the medium used. Besides, among the biofilm-producing isolates, those recovered from... Tipo: Info:eu-repo/semantics/article Palavras-chave: Biofilm; Pseudomonas aeruginosa; Cystic fibrosis; Antimicrobial resistance.
