Although vancomycin is a relatively narrow-spectrum antibiotic, it acts on a much broader range of organisms than fidaxomicin: it will kill several Gram- positive bacteria and, thereby, have an effect on normal microflora.
Is vancomycin a broad spectrum antibiotic?
Vancomycin is a broad spectrum antibiotic that has activity against methicillin-resistant strains of Staphylococcus aureus and is generally reserved for serious drug resistant gram-positive infections.
What class of antibiotics is vancomycin?
Vancomycin is in a class of medications called glycopeptide antibiotics. It works by killling bacteria in the intestines. Vancomycin will not kill bacteria or treat infections in any other part of the body when taken by mouth.
Which antibiotics are broad and narrow spectrum?
Examples of narrow-spectrum antibiotics are the older penicillins (penG), the macrolides and vancomycin. Examples of broad-spectrum antibiotics are the aminoglycosides, the 2nd and 3rd generation cephalosporins, the quinolones and some synthetic penicillins.Is vancomycin bacteriostatic or bactericidal?
While vancomycin is bactericidal against all susceptible Gram-positive pathogens it exerts only bacteriostatic activity against enterococci and needs to be combined with another agent, usually an aminoglycoside, to achieve bactericidal activity.
What is meant by narrow-spectrum antibiotics?
A narrow-spectrum antibiotic is an antibiotic that is only able to kill or inhibit limited species of bacteria.
Which antibiotic has the broadest spectrum?
- Azithromycin.
- Carbapenems (e.g. imipenem)

- Quinolones (e.g. ciprofloxacin)
- Tetracycline-class drugs (except sarecycline)
- Chloramphenicol.
- Ticarcillin.
- Trimethoprim/sulfamethoxazole (Bactrim)
Is Bactrim broad-spectrum?

Article first time published onIs vancomycin Gram positive or negative?
Vancomycin is active only with respect to Gram-positive bacteria. It is the most powerful of all of the known antibiotics with respect to S. aureus and Staphylococcus epidermidus, including methicillin- and cephalosporin-resistant strains.
Is vancomycin a penicillin?
Vancomycin is an antibacterial medication in the glycopeptide class. [7] Like penicillin, vancomycin prevents cell wall synthesis in susceptible bacteria.
Is vancomycin a macrolide?
These antibiotics include: capreomycin, a polypeptide antibiotic that has been used to treat patients with drug-resistant tuberculosis, particularly in developing nations; the macrolides, including erythromycin, azithromycin and clarithromycin; and vancomycin.
Which antibiotics are bactericidal?
- Aminoglycosides: Tobramycin, gentamicin, amikacin.
- Beta-lactams (penicillins, cephalosporins, carbapenems): Amoxicillin, cefazolin, meropenem.
- Fluoroquinolones: Ciprofloxacin, levofloxacin, moxifloxacin.
- Glycopeptides: Vancomycin.
- Cyclic Lipopeptides: Daptomycin.
- Nitroimidazoles: Metronidazole.
What do you mean by bactericidal?
The definitions of “bacteriostatic” and “bactericidal” appear to be straightforward: “bacteriostatic” means that the agent prevents the growth of bacteria (i.e., it keeps them in the stationary phase of growth), and “bactericidal” means that it kills bacteria.
Is cephalexin bactericidal or bacteriostatic?
Cephalexin is a bactericidal agent that acts by the inhibition of bacterial cell-wall synthesis.
Is amoxicillin a broad or narrow-spectrum?
The American Academy of Pediatrics recommends penicillin or amoxicillin, which are both narrow-spectrum antibiotics, as first-line therapy for most children with acute otitis media8; however, clinical trials have used amoxicillin-clavulanate, which is a broad-spectrum antibiotic, to compare with placebo for acute …
Is Cipro a narrow-spectrum antibiotic?
Ciprofloxacin is a broad-spectrum antibiotic that was once used to treat a wide range of infections, especially respiratory and urinary tract infections.
Is tetracycline broad or narrow spectrum?
Tetracyclines are broad-spectrum agents, exhibiting activity against a wide range of gram-positive and gram-negative bacteria, atypical organisms such as chlamydiae, mycoplasmas, and rickettsiae, and protozoan parasites.
Is Phenoxymethylpenicillin broad-spectrum?
Phenoxymethylpenicillin is a broad spectrum beta-lactam antibiotic with bactericidal action against Gram-positive bacteria and Gram-negative cocci. Its antimicrobial action is similar to that of benzyl penicillin.
Is erythromycin broad or narrow spectrum?
Penicillin, tetracycline and erythromycin are broad-spectrum drugs, effective against gram-positive and gram-negative microorganisms.
Is Keflex a narrow spectrum antibiotic?
Cefalexin is a broad-spectrum antibiotic, which means that it is active against a wide variety of germs (bacteria). It is used to treat bacterial infections such as urinary tract infections, skin infections, chest and throat infections, ear infections and dental infections.
Is sulfamethoxazole narrow or broad spectrum?
They classified amoxicillin and cephalexin as narrow-spectrum antibiotics, and all others (cefuroxime, amoxicillin-clavulanate, sulfamethoxazole-trimethoprim, cefdinir, cefixime and ciprofloxacin) as broad-spectrum antibiotics.
Is cephalexin a broad spectrum antibiotics?
Cephalexin has a broad spectrum of antimicrobial action; it is active with respect to Gram-positive and Gram-negative microorganisms.
Is chloramphenicol broad or narrow spectrum?
Chloramphenicol is a synthetically manufactured broad-spectrum antibiotic. It was initially isolated from the bacteria Streptomyces venezuelae in 1948 and was the first bulk produced synthetic antibiotic.
Is doxycycline a narrow spectrum antibiotic?
Background: Doxycycline is an broad-spectrum antimicrobial agent, it remains an inexpensive alternative for the treatment of community-acquired respiratory infections and urinary tract infections.

What is the spectrum of azithromycin?
Azithromycin is a broad-spectrum macrolide antibiotic with bacteriostatic activity against many Gram-positive and Gram-negative bacteria including Bordetella pertussis and Legionella species. It also has activity against Mycoplasma pneumoniae, Treponema pallidum, Chlamydia species and Mycobacterium avium complex.
Is vancomycin anaerobic or aerobic?
Vancomycin-imipenem treats both regions very effectively, reduces total luminal bacteria, and eliminates specific aerobic and anaerobic organisms.
Does vancomycin work on Gram negative?
Many antibiotics, such as vancomycin, which like β-lactam antibiotics targets the cell wall peptidoglycan, are ineffective against Gram-negative bacteria, simply because they have chemical properties that do not allow them to utilize these pathways to effectively penetrate the outer membrane.
Is zosyn broad spectrum?
It should be emphasized again that Zosyn is a broad-spectrum antibiotic that covers many gram positive, gram negative (including pseudomonas), and anaerobic organisms.
