The cephalosporins (sg. /ˌsɛfələˈspɔːrᵻn, ˌkɛ-, -loʊ-/) are a class of β-lactam antibiotics originally derived from the fungus Acremonium, which was previously known as "Cephalosporium".
Together with cephamycins, they constitute a subgroup of β-lactam antibiotics called cephems. Cephalosporins were discovered in 1945 and were first sold in 1964.
