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).
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.
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.
Eye, ear or bladder infections; usually applied directly to the eye or inhaled into the lungs; rarely given by injection, although the use of intravenous colistin is experiencing a resurgence due to the emergence of multi drug resistant organisms. Kidney and nerve damage (when given by injection)
Chickenpox, is a highly contagious skin disease caused by the varicella-zoster virus (VZV). [33] It is characterized by pruritic blister-like rash which may cover entire body, affecting all age groups. [33] [34] Rates of chickenpox are higher in countries which lack adequate immunization programs. In 2014, it has been estimated that global ...
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]
Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
Linezolid (Zyvox), which is available for intravenous administration and also has the advantage of having excellent oral bioavailability. Posizolid , which appears to have excellent, targeted bactericidal activity against all common gram-positive bacteria, regardless of resistance to other classes of antibiotics.
