The in vitro activity of a new oral antimicrobial agent, norfloxacin (MK-0366), was compared with those of nalidixic acid, nitrofurantoin, co-trimoxazole, trimethoprim, sulfamethoxazole, cinoxacin, tetracycline, ampicillin, carbenicillin, and cephalexin against 628 urinary bacterial isolates. Norfloxacin was the most active antimicrobial agent tested against the gram-negative bacilli. It was le...
Frequent monitoring of antimicrobial susceptibility in bacteria from any source (i.e. animal, food or human) is extremely valuable activity to ensure global public health. The acquired resistance among pathogenic bacteria may become evident clinically in events which fail to get the expected therapeutic response of an antimicrobial agent which had been successfully used for many years. In such ...
