Amoxicillin is recommended for the treatment of non-beta-lactamase-producing Haemophilus influenzae infections, while a second- or third-generation cephalosporins or beta-lactams combined with beta-lactamase inhibitors (e.g., amoxicillin–clavulanate) are preferred for infections caused by beta-lactamase-producing bacteria [2,3,4]. Here, LACTB is linked to infection.
