What is the effect of glycopeptide antibiotics?
Glycopeptides are considered drugs of last resort for the treatment of life-threatening infections caused by Gram-positive bacteria. They inhibit bacterial growth by interfering with cell wall biosynthesis. This occurs through binding to and sequestering lipid II from the action of bacterial enzymes.
What are the main causes of antibiotic resistance?
In summary, the 6 main causes of antibiotic resistance have been linked to:
- Over-prescription of antibiotics.
- Patients not finishing the entire antibiotic course.
- Overuse of antibiotics in livestock and fish farming.
- Poor infection control in health care settings.
- Poor hygiene and sanitation.
What is glycopeptide antibiotic?
Significant glycopeptide antibiotics include the anti-infective antibiotics vancomycin, teicoplanin, telavancin, ramoplanin and decaplanin, corbomycin, complestatin and the antitumor antibiotic bleomycin. Vancomycin is used if infection with methicillin-resistant Staphylococcus aureus (MRSA) is suspected.
How do bacteria become resistant to glycopeptides?
Resistance has manifested itself largely through the expression of genes that encode proteins that reprogram cell wall biosynthesis and thus evade the action of the antibiotic in the enterococci, though recently new mechanisms have appeared that afford resistance and tolerance in the more virulent staphylococci and …
Why are glycopeptide antibiotics effective against MRSA?
Glycopeptide antibiotics act primarily by inhibiting cell wall synthesis of bacteria. Vancomycin and teicoplanin have antimicrobial activity against almost all types of Gram-positive organisms including MRSA although their spectra of activity tend to be limited to Gram-positive organisms.
What are the side effects of vancomycin?
Side Effects
- Bladder pain.
- bloating or swelling of the face, arms, hands, lower legs, or feet.
- bloody or cloudy urine.
- decreased urine.
- difficult, burning, or painful urination.
- frequent urge to urinate.
- increased thirst.
- irregular heartbeat.
What factors cause drug resistance?
Misuse and overuse of antimicrobials are the main drivers in the development of drug-resistant pathogens. Lack of clean water and sanitation and inadequate infection prevention and control promotes the spread of microbes, some of which can be resistant to antimicrobial treatment.
What causes resistance to drugs?
Antimicrobial resistance (AMR), or drug resistance, develops when microbes, including bacteria, fungi, parasites, and viruses, no longer respond to a drug that previously treated them effectively.

Is vancomycin a glycopeptide?
Glycopeptides of the clinically important antibiotic drugs are glycosylated cyclic or polycyclic nonribosomal peptides. Glycopeptides such as vancomycin and teicoplanin are often used for the treatment of gram-positive bacteria in patients.
What is a glycopeptide antibiotic?
Glycopeptides are considered antibiotics of last resort for the treatment of life-threatening infections caused by relevant Gram-positive human pathogens, such as Staphylococcus aureus, Enterococcusspp. and Clostridium difficile.
Is vancomycin a glycopeptide antibiotic?
Glycopeptides (vancomycin and teicoplanin) The glycopeptide antibiotic vancomycin is used intravenously in endocarditis and other serious infections caused by Gram-positive cocci including multi-resistant Staphylococci (MRSA). It is also used orally in the treatment of antibiotic-associated (pseudomembranous) colitis.
What is a GPA antibiotic used to treat?
Glycopeptide antibiotics (GPAs) are frequently used to treat life-threatening infections caused by multidrug-resistant Gram-positive pathogens, such as Staphylococcus aureus, Enterococcusspp. and Clostridium difficile.
