Enterococcus faecalis

Enterococcus faecalis is a gram positive, catalase negative bacteria that is an increasing worry for clinicians as a cause of hospital-acquired infections. It is a normally occurring bacteria in the intestines, bile ducts, and genitourinary system. However, when there is local overgrowth due to other flora being suppressed (especially by cephalosporins) it causes clinically important urinary and biliary tract infections. Interestingly, Enterococcus faecalis has an outer capsule that prevents it from being degraded by bile salts. Of particular worry is the ability of Enterococcus faecalis to enter the bloodstrean and colonize heart valves in subacute bacterial endocarditis. There is a heightened risk of subacute bacterial endocarditis in heart valves that have previously been damaged by Group A streptococcus such as in rheumatic fever. All strains of E. faecalis are resistant to cephalosporins and there are now some strains resistant to vancomycin. The diagnosis is made by culturing in 40% bile and 6.5% sodium chloride solution. Treatment most commonly is ampicillin or vancomycin if no resistance is present and an aminoglycoside The post Enterococcus faecalis appeared first on InsideSurgery Medical Information Blog.

Characterizations of this material were examined by using XRD, SEM, FT-IR, TGA-DTG and BET methods. Factors affecting the uptake of methylene blue, including pH, adsorption time, and MB initial concentration were also studied. The measured da...

ZaytsevAbstractThe control of the biotechnological reactors for the wastewater processing and for multiple biotechnological syntheses often requires the in situ monitoring of the current concentration of dissolved molecular oxygen (DO) within the reactor. The method of determining of DO based on the quenching of the indicator dye phosphorescence is becoming readily used due to be unaffected by sulfur-containing compounds and relatively insensitive to hydrodynamic cond...

In this study, we developed a multifunctional thermal management nanocomposite paper (NPG) consisting of cationic poly (diallyldimethylammonium chloride) (PDDA)-functionalized graphene oxide (PG) and nanodiamond (ND). Due to the functionalized reduction of graphene oxide (GO) by PDDA as well as electrostatic interactions between the positively charged PG and negatively charged ND, a three-dimensional (3D) hybrid NPG paper constructed by two-dimensional (2D) PG layers and zero-dimensional (0D) ND particles was successfully prepared via a vacuum-assisted self-assembly strategy. The resulting NPG papers were characterized by ...
