Abstract excerpt

Recently, the instance of beta-lactamase-negative ampicillin (AMP)-resistant (BLNAR) strains of Haemophilus influenzae has exhibited a marked increase in Japan. Our group determined the MICs of 160 clinical isolates of H. influenzae at a university hospital in Okinawa, the southernmost part of Japan, and found that 27 strains were BLNAR, while 24 strains were beta-lactamase-producing. Among the latter, 2 strains...
