An antibiotic is a type of antimicrobial substance active against bacteria.It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections.
The following is a list of antibiotics. The highest division between antibiotics is bactericidal and bacteriostatic. Bactericidals kill bacteria directly, whereas bacteriostatics prevent them from dividing. However, these classifications are based on laboratory behavior.
Survey prescriber knowledge about antibiotics, antifungal or antiviral drugs. Provide targeted education about particular antibiotics, or one specific antimicrobial at a time, as well as empiric treatment for syndromes versus culture directed treatment. Assist in making duration more visible to prescribers. Some institutions use automatic stop ...
Again, antibiotics only work against bacterial infections. “It does not work against viruses or fungus,” says Tran. “The confusion always comes up around wintertime because of the flu.
Antimicrobial use has been common practice for at least 2000 years. Ancient Egyptians and ancient Greeks used specific molds and plant extracts to treat infection. [5]In the 19th century, microbiologists such as Louis Pasteur and Jules Francois Joubert observed antagonism between some bacteria and discussed the merits of controlling these interactions in medicine.

Tetracyclines are generally used in the treatment of infections of the urinary tract, respiratory tract, and the intestines and are also used in the treatment of chlamydia, especially in patients allergic to β-lactams and macrolides; however, their use for these indications is less popular than it once was due to widespread development of resistance in the causative organisms.
The action is usually not inhibitory and irreversible even with the withdrawal of the drug. Mammalian cells are not vulnerable to the effect of Tetracycline as these cells contain no 30S ribosomal subunits so do not accumulate the drug. [26] This accounts for the relatively small off-site effect of tetracycline on human cells. [27]
The two types of beta-lactamases work on the basis of the two basic mechanisms of opening the β-lactam ring. [2] The SBLs are similar in structure and mechanistically to the β-lactam target penicillin-binding proteins (PBPs) which are necessary for cell wall building and modifying. SBLs and PBPs both covalently change an active site serine ...
