Antibiotic (for example tetracycline) is a broad-spectrum agent effective against a wide variety of bacteria including Hemophilus influenzae, Streptococcus pneumoniae, Mycoplasma pneumoniae, Chlamydia psittaci, Chlamydia trachomatis, Neisseria gonorrhoeae, and many others.
Antibiotics allows the infected body to recover by producing its own defenses and overcome the infection.
Unlike previous treatments for infections such as poisons such as strychnine, antibiotics were labelled as medicines that targets disease without harming the host.
The effectiveness of individual antibiotics varies with the location of the infection and the ability of the antibiotic to reach this place. Oral antibiotics are the simplest approach when effective, with intravenous antibiotics reserved for more serious cases. Antibiotics may sometimes be administered topically, as with eyedrops or ointments.
A number of different antibiotics are used to treat ulcers caused by the bacteria Helicobacter pylori. Usually a triple therapy using two antibiotics, usually clarythromycin plus either metronidazole or amoxicillin, along with a proton pump inhibitor is used.
A urinary track infection is usually caused by a bacterium known as Escherichia Coli.
Amoxicillin and Ampicillin are included in this category and they used to be the predominant antibiotics for infections caused by E. Coli.
