Antibacterial activities of cefetamet against clinically isolated strains from community acquired respiratory tract infections (II)

Abstract

Antibacterial activities of cefetamet (CEMT) against clinically isolated strains from patients with community acquired respiratory tract infections were compared to those of other oral beta-lactam antibiotics in the period from January to March 1994. The following results were obtained. 1. CEMT showed strong antibacterial activities against three major pathogens causing community acquired respiratory tract infections, Streptococcus pyogenes, Streptococcus pneumoniae, and Haemophilus influenzae. However, antibacterial activities of CEMT against benzylpenicillin (PCG)-insensitive S. pneumoniae (PISP) and PCG-resistant S. pneumoniae (PRSP) were slightly weaker than of those of some the reference antibiotics. 2. No MIC value changes of CEMT were observed from year to year against Moraxella subgenus Branhamella catarrhalis and Klebsiella pneumoniae.
