Of the following, which organism would be best described as a gram-positive coccus that is a normal colonizer of the gastrointestinal (GI) tract that enters the bloodstream causing bacteremia and is thought to be closely associated with GI disorders including colon cancer?

Match each biochemical test with the correct pair of organisms that would serve as positive and negative controls (respectively).

A mother brings her lethargic, feverish 2-year old child into the emergency department. The baby is diagnosed with meningitis and the doctor does a spinal tap. The direct smear of the cerebrospinal fluid (CSF) shows many tiny gram-negative rods. The culture revealed that nothing grew on blood or MacConkey agars, but small, translucent colonies grew on Chocolate agar. What is the most probable identification of this organism?

A cerebral spinal fluid (CSF) from a neonate grows gram-positive cocci that are beta-hemolytic and catalase negative. The group of tests that would be most helpful in identifying the organism are:

A patient has a skin abscess that produces pus. The organism isolated from the wound grows on blood agar and appears as Gram-positive cocci. Which test should be performed next to begin identification of the organism?

A 2-year-old child experienced an upper respiratory infection 2 weeks prior to hospital admission. The patient was seen in the emergency room 3 days prior to admission with a high fever. Physical exam revealed an exudative pharyngitis and bilaterally enlarged lymph nodes. The child’s condition worsened and he eventually developed into respiratory distress. Of the following choices, the disease that is most likely causing these symptoms is:

Match each Gram stain component in with its correct function.

What disease can newborns acquire during delivery through a birth canal infected with Neisseria gonorrhoeae?

Each of the following are indicative of Neisseria gonorrhoeae infection.  One of these scenarios will require additional testing to rule out Gonorrhoeae.  Which one requires additional testing?
