A patient presented to the ED with diarrhea of several days. The physician ordered a stool culture.  How the culture was plated and incubated has to stay a secret, however, the culture grew moist raised spreading colonies that were oxidase positive. Gram stain revealed weakly gram-negative rods in classic “gull-wing” shapes. A hanging drop motility test showed darting motility confirming the identification of what species?

Used culture plates should be disposed of in _____________ biohazard bags.

Neisseria gonorrhoeae grows on what selective plate? 

__________[1]______________ test is used to differentiate bacterial organisms isolated from urine samples. ___________[2]____________________ (top) is _______[3]_________ to the ingredient in the disk, as indicated by the lack of a zone of inhibition around the disk.

The pic below provides a direct Gram-stained smear of cerebrospinal fluid (CSF) of a very sick infant. 1. How would you report this (bacteria only)? 2. What would be the presumptive ID?

The plate is SBA. The patient was a 3 year old with recurrent otitis media. The biochemical tests are as follows: gram positive cocci in pairs catalase negative optochin disk susceptible What is the presumptive organism?  

Name 2 of the most common hospital-acquired infections that are caused by Enterics. (worth 2 points each)

Report the Gram stain. The source is a blood culture.

Where are Enterics found?

The agar is SBA. What kind of colonies are presented on the plate and what is the presumptive organism?
