A metal worker sustains an eye injury in which a small metal fragment damages her cornea. The injury is treated with topical cortisone and antibiotic . She develops a corneal infection which rapidly invades the aqueous humor and iris. Culture produces a hyaline mold with a wooly lavender colony. Microscopic banana shaped multiseptate conidia are seen. This most likely is:

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?

A College of American Pathologists (CAP) survey was analyzed for alkaline phosphatase in duplicate with the following results 324 mU/ml and 330 mU/ml respectively. Both the normal and abnormal controls analyzed during the run were within the confidence range. The CAP survey results were reported as obtained. When the survey report came back, it was noted that the confidence range for the ALP was 295-310 mU/ml. This information reveals that:
