Microbial biofilms are involved in almost all infectious pathologies of the oral cavity. This has led to search for novel therapies specifically aimed at biofilm elimination. In this study, we used atomic force microscopy (AFM) visualize injuries and determine surface roughness, as well confocal laser scanning (CLSM) enumerate live dead bacterial cells, effects photodynamic therapy (PDT) on Enterococcus faecalis biofilms. The AFM images showed that PDT consisting methylene blue a 670-nm...
Clonal dissemination of multidrug-resistant Pseudomonas aeruginosa (MDRPA) is a major concern worldwide. The aim this study was to explore the mechanisms leading carbapenem resistance an MDRPA clone. Isolates were obtained from surgical wound, sputum, urine and blood culture. Pulsed-field gel electrophoresis (PFGE) showed high genomic homogeneity these isolates confirmed circulation endemic clone belonging serotype O4. Outer membrane protein (OMP) bands visualized by SDS-PAGE, meropenem...
The treatment of patients suffering from Aspergillus diseases is hampered due to infections with fumigatus that are already resistant medical azoles. Previous work has suggested A. likely gains resistance through environmental azole exposure in so-called hot spots. Here, we investigated dynamics over time at three sites which farmers used fungicides for crop protection. Over 16 months, 114 samples were taken stockpiles decaying plant waste. and fungicide residues ubiquitously present the On...
Objective: The prospective study compares, in split-mouth design, the use of two different suture materials, silk vs. Teflon-coated, multi-filament braided polyester threads suture. Material and methods: Ten edentulous or partially patients were surgically treated for implant installation. Each side was sutured with either, randomly selected one other material. Seven days postsurgically, sutures removed three knots per patient collected microbiological testing. Additionally, a piece each...
To visualize by atomic force microscopy the alterations induced on Enterococcus. faecalis surface after treatment with 2 types of laser: Erbium chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser and Diode laser.Bacterial suspensions from overnight cultures E. were irradiated during 30 seconds laser-lights at 1 W power, leaving one untreated sample as control. Surface treated visualized (AFM) its roughness determined.AFM imaging showed that high potency both cell morphology resulted...
