[A review of new cephalosporin antibiotics].

The authors discuss some properties of recent cephalosporin antibiotics and the antibiotics effectiveness in particular of more recent generations of cephalosporins. The increasing resistance to penicillins and other antibiotics called for use effective cephalosporins of new generations. While cephalosporins of the 1st generation (cephalothin, cephazoline, and oral cephaloridine or cephaclor) are effective against Gram-positive bacteria, haemophilus bacteria and Klebsiellae, the resistance of other bacteria even against these antibiotics is increasing.
