Diversity of Ampicillin-Resistance Genes in <i>Haemophilus influenzae</i> in Japan and the United States

1 Mar 2003

Abstract excerpt

Clinical isolates of Haemophilus influenzae from Japan (n = 296) and the United States (n = 100) were tested by the microdilution method for susceptibility in vitro to 10 beta-lactam antibiotics and molecular mechanisms of beta-lactam resistance. For all isolates, PCR was used to identify six elements, including beta-lactamase-producing ampicillin (AMP)-resistance (BLPAR) and beta-lactamase-nonproducing...
