Ask a question


The cephalosporins are a class of bactericidal antibiotics similar to penicillin. There exist four generations, of which the properties are slightly different, but all destroy and prevent bacteria from reproducing. They are especially efficient against Gram-negative bacteria, such as Enterobacter, Haemophilus, and Klebsiella bacteria. Because of their properties, cephalosporins are recommended for a large number of infections, such as respiratory, urinary, and genital infections. They are also used in certain cases of otitis and meningitis.
