How a single fungus gave rise to a versatile class of antibiotics
In short: Discover how cephalosporins work to stop bacterial growth. This video breaks down their mechanism of action, their classification into generations, and how they are used to treat various infections.
Cephalosporins are β-lactam antibiotics originally isolated from the fungus Cephalosporium acremonium. They function by inhibiting the synthesis of the bacterial cell wall. Because of modifications to the β-lactam ring, over 20 derivatives now exist with varying antibacterial properties.
The class is organized into generations based on their activity. First-generation drugs like cephalothin target gram-positive and certain gram-negative bacteria, such as Streptococcus and E. coli. Later generations, including second and third-generation options like ceftazidime, offer increased effectiveness against resistant gram-negative species. Some derivatives can even penetrate cerebrospinal fluid to treat meningitis.
