Quiz Questions:

  1. A client brings you a fecal sample from her 6 month old male cat (indoor/outdoor).  The client's 2 year old son was caught playing in the cat's litter box and had some of the feces (the actual sample brought in) on his hands and face.  You ran a ZnSO4 flotation on the sample and the results are shown below (the objects measure about 10 Ám).
    1. Identify the parasite.
    2. The owner is concerned for her son's health, given what you see at the right, should she be concerned?
