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.
Treatment of Clostridioides (formerly Clostridium) difficile infection. [8] May be more narrow-spectrum than vancomycin, resulting in less bowel microbiota alteration. [9] Nausea (11%), vomiting, and abdominal pain. [10] Bactericidal in susceptible organisms such as C. difficile by inhibiting RNA polymerase, thereby inhibiting protein synthesis ...
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.
The effective treatment of MRSA with linezolid has been successful [87] in 87% of people. Linezolid is more effective in soft tissue infections than vancomycin. [89] [1] This is compared to eradication of infection in those with MRSA treated with vancomycin. Treatment with vancomycin is successful in approximately 49% of people. [1]
Glycopeptide antibiotics are a class of drugs of microbial origin that are composed of glycosylated cyclic or polycyclic nonribosomal peptides.Significant glycopeptide antibiotics include the anti-infective antibiotics vancomycin, teicoplanin, telavancin, ramoplanin, avoparcin and decaplanin, corbomycin, complestatin and the antitumor antibiotic bleomycin.
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.
Cellulitis occurred in about 21.2 million people in 2015. [7] In the United States about 2 of every 1,000 people per year have a case affecting the lower leg. [1] Cellulitis in 2015 resulted in about 16,900 deaths worldwide. [8] In the United Kingdom, cellulitis was the reason for 1.6% of admissions to a hospital. [6]
