Some common medications within this class include the following: These medications play a crucial […]

This is a large group of beta-lactam antibiotics used to target a variety of gram-positive and gram-negative bacteria. There are five generations of Cephalosporins currently. These antibiotics are similar to another group of beta-lactam antibiotics called the Pencillins. Their similarity arises from their chemical structures because both types are made up of a beta-lactam ring. […]

Fluoroquinolones, also called Quinolones, are a group of antibiotics helpful for treating gram-negative and gram-positive bacterial infections. The gram-negative infections this group treats include Haemophilus influenzae, Neisseria gonorrhoeae, Chlamydia, Escherichia coli, Klebsiella pneumoniae, Salmonella, Pseudomonas aeruginosa etc. And the gram-positive infections include Streptococcus pneumoniae, Enterococcus, Staphylococcus aureus etc. Because this antibiotic group can target the […]

Macrolides are a class of antibiotics most helpful against gram-positive bacteria like Streptococcal, Corynebacterium diphtheria (which causes diphtheria), and Staphylococcal infections. However, it is not effective against the gram-positive group of bacteria called Enterococcus. Macrolides can also target some gram-negative bacteria like Salmonella, Chlamydia, H. pylori, Legionella, Gonorrhea, and H. influenza (causes epiglottis). Therefore, this […]
