Growth on a BAP shows large, gray colonies that are non-hemolytic and ground glass. The gram stain shows large, gram positive rods. To rule out Bacillus anthracis, what tests should be performed next?

Given the following results, what is the most likely organism?     – small, white, gamma colony     – catalase positive     – coagulase negative

Bacteremia is the presence of bacteria in the blood with clinical signs and symptoms.

The most important variable in the recovery of organisms in adult patients with bacteremia is:

Yeast is seen in a wound gram stain. The gram stain is reported as: gram positive yeast

Gram negative diplococci will have growth on BAP, CHOC, and MAC

This select agent produces smooth, creamy white colonies at 24 hours of growth on BAP and CHOC. The gram stain shows small, gram negative rods arranged in long, parallel bundles.

What disk is used in the laboratory to check if S. aureus has methicillin resistance?

A cerebrospinal fluid (CSF) sample collected from a child yields the following results: turbid and cloudy, very high total protein levels, and very low glucose levels.  What would the probable diagnosis be?

Three sets of blood cultures were obtained from an adult patient with fever and suspected endocarditis. The aerobic bottle of one set had growth of Staphylococcus epidermidis at 5 days of incubation. This indicates that:
