Enzymatic detachment of Staphylococcus epidermidis biofilms.
The gram-positive bacterium Staphylococcus epidermidis is the most common cause of infections associated with catheters and other indwelling medical devices. S. epidermidis produces an extracellular slime that enables it to form adherent biofilms on plastic surfaces. We found that a biofilm-releasing enzyme produced by the gram-negative periodontal pathogen Actinobacillus actinomycetemcomitans ...
متن کاملPenetration of rifampin through Staphylococcus epidermidis biofilms.
Rifampin penetrated biofilms formed by Staphylococcus epidermidis but failed to effectively kill the bacteria. Penetration was demonstrated by a simple diffusion cell bioassay and by transmission electron microscopic observation of antibiotic-affected cells at the distal edge of the biofilm.
متن کاملStrategies to control Staphylococcus epidermidis biofilms
Staphylococcus epidermidis is the staphylococci species most commonly associated with bacteremia and hospital-acquired infections and has recently arisen as the leading cause of infections related to indwelling medical devices such as vascular catheters, prosthetic joints and artificial heart valves. The prevalence of S. epidermidis in hospital-acquired infections is due to its ability to adher...
متن کاملInteraction between clarithromycin and biofilms formed by Staphylococcus epidermidis.
Interactions between clarithromycin and biofilms formed by Staphylococcus epidermidis were investigated by using a clarithromycin-resistant strain. Treatment of the colonization with a relatively low concentration of clarithromycin resulted in the eradication of slime-like structure and a decrease in the quantity of hexose. Another result was increased penetration of antibiotics through the bio...
متن کاملStaphylococcus epidermidis biofilms control by N-acetylcysteine and rifampicin.
Medical device-associated infections caused by Staphylococcus epidermidis usually involve biofilm formation and its eradication is particularly challenging. Although rifampicin has been proving to be one of the most effective antibiotics against S. epidermidis biofilms, its use as a single agent can lead to the acquisition of resistance. Therefore, we assessed the combined effect of rifampicin ...
