noun
cephalosporin
A class of β-lactam antibiotics originally derived from the fungus Acremonium. Used in medical and pharmacological contexts.
セファロスポリン系の抗生物質は、細菌の細胞壁合成を阻害する。
Cephalosporin antibiotics inhibit bacterial cell wall synthesis.
Both are β-lactam antibiotics, but cephalosporins have a broader spectrum of activity and are often used when penicillin resistance is a concern.
Borrowed from English 'cephalosporin', which derives from the genus name Cephalosporium (now Acremonium) of the fungus from which the first cephalosporin was isolated.
