We examined beta-lactamase productions by clinically isolated strains of bacteria. The results were as follows; 1. It appears that beta-lactamases produced by strains of five species of Staphylococcus spp. are mostly penicillinase (90%). Source of beta-lactamase producing strains of Haemophilus influenzae (23%) and all of Moraxella subgenus Branhamella catarrhalis: strains (100%) are "High & Low producer" strains. 2. A large proportion of beta-lactamase producing strains of Enterobacteriaceae and Bacteroides fragilis group appeared to be "High producer" 3. beta-lactamase producing abilities are different among glucose non-fermentative Gram-negative rods. It appears that some of the strains appeared to be "High producers".
