Size: 17 µm   Stage: [1] Most likely identification of the organism: [2]

The hair from a child with apparent ringworm of the scalp shows bright green fluorescence under a Wood’s lamp. Culture of the hair yielded a fungus with pectinate hyphae and no distinct conidial structures were seen. What is the most likely identity of the fungus?

Name the type of conidia shown:         

Associate the correct characteristic with the given yeast: Geotrichum candidum

An off-white, moist, yeast-like fungus is isolated from a blood culture. It does not produce mycelia on Cornmeal Tween 80 Agar, does not ferment sugars, and produces urease at 35ºC. Choose the most likely identification for this fungus.

Pick the fungus which would produce the hair perforation test results pictured below. (All photos show the same test result.)         

What category of stain is this (one word, no acronyms)? [1]   Name two specific stains that are used in this category – write out the full names: [2] [3]   Read/give the following results:             [4]                              [5]

Below are 2 LJs – one was covered in foil to prevent light exposure (left) and one was allowed light exposure (right). Compare the morphology between the 2 LJs once uncovered. What category would this organism be a part of?

You’ve smeared the organism growing on this Chocolate agar plate shown below and it is ACID-FAST. Other media plated such as LJ, 7H10, 7H11 bi-plate has little to no visible growth.  What organism would you suspect? Write out the genus and species:
