Beta-lactamase Producing Haemophilus Influenzae and their Susceptibility to Amoxicillin and Related Antibiotics
Seven strains out of 73 strains of H. influenzae isolated from 72 patients produced beta-lactamase and all of the beta-lactamase producing strains were isolated from patients with respiratory diseases. Of 6 strains serotyped by slide agglutination, 2 were type d, the remaining 4 were nontypable. All of the beta-lactamase producing H. influenzae were resistant to amoxicillin but sensitive to BRL-25,000, Ceftizoxime and Cefmenoxime.
