Experiments involving the cocultivation of four genera of beta-lactamase-positive (β-lac + ) bacteria and a beta-lactamase-negative (β-lac − ) N. gonorrhoeae on modified Thayer-Martin medium indicated that suppressed or inhibited β-lac + bacteria did not give false-positive results when isolated β-lac − colonies of gonococci were tested. Colonies were assayed for β-lac production by an adaptation of a microacidometric method in which bacteria could be tested before or after the addition of oxidase reagent.
