Association of Amino Acid Substitutions in Penicillin-Binding Protein 3 with β-Lactam Resistance in β-Lactamase-Negative Ampicillin-Resistant Haemophilus influenzae

The affinity of [(3)H]benzylpenicillin for penicillin-binding protein (PBP) 3A was reduced in 25 clinical isolates of β-lactamase-negative ampicillin (AMP)-resistant (BLNAR) Haemophilus influenzae for which the AMP MIC was ≥1.0 μg/ml. The affinities of PBP 3B and PBP 4 were also reduced in some stra...
