Spurious Ampicillin Resistance by Testing Haemophilus influenzae with Agar Containing Supplement C
AUTOR(ES)
Washington, John A.
RESUMO
Ampicillin resistance (minimal inhibitory concentration ≥10 μg/ml) in the absence of beta-lactamase activity by Haemophilus influenzae was noted in tests performed with Mueller-Hinton agar containing one lot of supplement C. All strains, except five with known resistance due to beta-lactamase activity, were inhibited by 0.6 μg or less of ampicillin per ml of chocolatized blood agar.
