Vancomycin is a glycopeptide antibiotic medication used to treat certain bacterial infections. [7] It is administered intravenously ( injection into a vein ) to treat complicated skin infections , bloodstream infections , endocarditis , bone and joint infections, and meningitis caused by methicillin-resistant Staphylococcus aureus . [ 8 ]
There are also strains of enterococci that have developed resistance to vancomycin referred to as vancomycin resistant enterococcus (VRE). Agents classified as fourth-line (or greater) treatments or experimental therapies could be considered by default to be drugs of last resort due to their low placement in the treatment hierarchy.
This can quickly determine if there are bacterial or viral species present in the CSF. If these are ruled out, as well as other causes such as parasitic or fungal causes, then the cause of the meningitis is likely noninfectious in nature. [2] DIAM is among these noninfectious causes of aseptic meningitis. [citation needed]
As one can see, it would take many days for the total amount of drug within the body to come close to 1 gram (1000 mg) and achieve its full therapeutic effect. For a drug such as this, a doctor might prescribe a loading dose of one gram to be taken on the first day. That immediately gets the drug's concentration in the body up to the ...
Linezolid is an antibiotic used for the treatment of infections caused by Gram-positive bacteria that are resistant to other antibiotics. [9] [10] Linezolid is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA).
Enterococcus faecium has been a leading cause of multi-drug resistant enterococcal infections over Enterococcus faecalis in the United States. Approximately 40% of medical intensive care units reportedly found that the majority, respectively 80% and 90.4%, of device-associated infections (namely, infections due to central lines, urinary drainage catheters, and ventilators) were due to ...
The diagnosis of vancomycin-resistant Staphylococcus aureus (VRSA) is performed by performing susceptibility testing on a single S. aureus isolate to vancomycin. This is accomplished by first assessing the isolate's minimum inhibitory concentration (MIC) using standard laboratory methods, including disc diffusion, gradient strip diffusion, and automated antimicrobial susceptibility testing ...
Vancomycin. Six different types of vancomycin resistance are shown by enterococcus: Van-A, Van-B, Van-C, Van-D, Van-E and Van-G. [4] The significance is that Van-A VRE is resistant to both vancomycin and teicoplanin, [5] Van-B VRE is resistant to vancomycin but susceptible to teicoplanin, [6] [7] and Van-C is only partly resistant to vancomycin.
