Which of the following statements relating to healthcare utlization is false?

A small, gram-negative coccobacillus is isolated from a lymph node aspirate of a hunter with ulceroglandular symptoms after handling wild rabbits. The organism grows poorly on standard media, but appears after 48 hours on cysteine-enriched chocolate agar. The organism is oxidase negative and provides a weak postive catalase reaction. The technologist presumptively identifies the isolate as Francisella tularensis.  What is the next best step?

A pediatric patient is brought to the clinic with acute onset of bilateral conjunctival redness, tearing, and crusting around the eyes. Several classmates have developed similar symptoms. A conjunctival swab is collected for culture. Gram stain shows small, pleomorphic gram-negative coccobacilli. What is the most common cause of the described illness?

The gram stain of a pericardial fluid shows many tiny gram-negative coccobacilli. There is no growth on blood agar at 24 hours, but the chocolate agar shows small translucent colonies. The microbiologist performs a porphyrin test, which is positive.  The organism should be identified as:

Select which media types will support the growth of Haemophilus influenzae: (Choose all that apply)

(WCSP25)  50 g of each salt were placed in separate beakers and mixed with 100 g of water at room temperature (25 oC).   The solutions were heated to 100 oC and cooled back to 25 oC carefully.  Only one solution contained a precipitate after following these steps.   a. The solution of had a precipitate and it was . b. The KBr solution is .
