A direct smear on an endocervical specimen revealed intracellular gram-negative, kidney-bean-shaped diplococci. The specimen was inoculated onto a Modified Thayer-Martin (MTM) Agar plate, and after 24-hours incubation under CO2, grayish-white, translucent, glistening colonies resembling gonococci were observed. The technologist subcultured the colony to chocolate agar. Growth from the chocolate agar was used to perform Cysteine Tryptic digest Agar (CTA) carbohydrate utilization tests with glucose, maltose, sucrose, lactose and fructose. After 24 hours incubation the technologist saw that both glucose and maltose had been degraded. What is the best next step?
