The bacteriostatic agents included tigecycline, linezolid, macrolides, sulphonamides, tetracyclines and streptogramins. The bactericidal agents included β-lactam antibiotics, glycopeptide antibiotics, fluoroquinolones and aminoglycosides.

What are bactericidal and bacteriostatic agents?
Definition of Bacteriostatic/Bactericidal Activity. 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 Penicillin a bactericidal or bacteriostatic?
Penicillins are bactericidal agents that exert their mechanism of action by inhibition of bacterial cell wall synthesis and by inducing a bacterial autolytic effect.
Which antibiotics are bactericidal?
Bactericidal antibiotics that inhibit cell wall synthesis: the beta-lactam antibiotics (penicillin derivatives (penams), cephalosporins (cephems), monobactams, and carbapenems) and vancomycin. Also bactericidal are daptomycin, fluoroquinolones, metronidazole, nitrofurantoin, co-trimoxazole, telithromycin.
Is amoxicillin bacteriostatic or bactericidal?
As a beta-lactam antibiotic, amoxicillin is mainly bactericidal. Inhibits third and final stage of bacterial cell wall synthesis by preferentially binding to specific PBPs located inside the bacterial cell wall.
How does bacteriostatic work?
Bacteriostatic antibiotics limit the growth of bacteria by interfering with bacterial protein production, DNA replication, or other aspects of bacterial cellular metabolism. Bacteriostatic antibiotics must work together with the immune system to remove the microorganisms from the body.
What is bacteriostatic used for?
The term "bacteriostatic antibiotics" is used to describe medications whose mechanism of action stalls bacterial cellular activity without directly causing bacterial death.
What bacteria does penicillin kill?
Penicillin is a widely used antibiotic prescribed to treat staphylococci and streptococci bacterial infections. Penicillin belongs to the beta-lactam family of antibiotics, the members of which use a similar mechanism of action to inhibit bacterial cell growth that eventually kills the bacteria.
What is natural penicillin?
The two so-called natural penicillins are both produced biosynthetically from Penicillium chrysogenum by fermentation. Benzylpenicillin (penicillin G) is formed if phenylacetic acid is added to the culture medium and Phenoxymethylpenicillin (penicillin V) is formed when phenoxyacetic acid is added.
Is ciprofloxacin bacteriostatic or bactericidal?
For instance, ciprofloxacin, a fluoroquinolone, exhibits a bacteriostatic activity when the replication of DNA is inhibited by inhibiting DNA gyrase and a bactericidal activity caused by bacterial DNA fragmentation.
Which antibiotics are bacteriostatic or bactericidal?
The bacteriostatic agents included tigecycline, linezolid, macrolides, sulphonamides, tetracyclines and streptogramins. The bactericidal agents included β-lactam antibiotics, glycopeptide antibiotics, fluoroquinolones and aminoglycosides.
How do you determine if an antibiotic is bactericidal or bacteriostatic?
Defining bactericidal and bacteriostatic
The formal definition of a bactericidal antibiotic is one for which the ratio of MBC to MIC is ≤ 4, while a bacteriostatic agent has an MBC to MIC ratio of > 4.
Why do doctors prescribe bacteriostatic antibiotics?
Bacteriostatic antibiotics limit the growth of bacteria by interfering with bacterial protein production, DNA replication, or other aspects of bacterial cellular metabolism. They must work together with the immune system to remove the microorganisms from the body.
