The in vitro activity of cefaclor against 556 clinical isolates of gram-positive and gram-negative bacteria was compared with that of other cephalosporins. Cefaclor had activity similar to that of cephalexin against gram-positive bacteria. It showed greater activity against Haemophilus strains than did cephalexin and inhibited beta-lactamase-producing Haemophilus isolates. Cefaclor was more active than cephalexin or cephalothin against Escherichia coli, Salmonella, and Shigella isolates but did not act against Serratia, Acinetobacter, indole-positive Proteus, or Bacteroides isolates. Cefaclor was resistant to type III (TEM) beta-lactamases but was destroyed by type I beta-lactamases and, to a lesser degree, by type IV and type V beta-lactamases.
将头孢克洛对556株革兰氏阳性和革兰氏阴性细菌临床分离株的体外活性与其他头孢菌素进行了比较。头孢克洛对革兰氏阳性菌的活性与头孢氨苄相似。它对嗜血杆菌菌株的活性比头孢氨苄更强,并能抑制产β-内酰胺酶的嗜血杆菌分离株。头孢克洛对大肠杆菌、沙门氏菌和志贺氏菌分离株的活性比头孢氨苄或头孢噻吩更强,但对沙雷氏菌、不动杆菌、吲哚阳性变形杆菌或拟杆菌分离株无作用。头孢克洛对III型(TEM)β-内酰胺酶具有抗性,但被I型β-内酰胺酶破坏,在较小程度上也被IV型和V型β-内酰胺酶破坏。
