'''These rapidly spinning ciliated organisms were seen on the examination of a skin scrape (×100).'''
<br />
<FlashCard questions="2">
|q1=Name the organism.
|a1=
''Trichodina'', a ciliated protozoan parasite which is a common cause of skin and gill disease in ornamental fish.
|l1=
|q2=How is a skin scraping prepared?
|a2=
A skin scrape is prepared by obtaining a small quantity of mucus from the skin surface of a freshly dead or anesthetized fish.
Areas of predilection for skin parasites are those adjacent to the fins and it is a good approach to obtain material from these sites.
The mucus is suspended in a small quantity of water on a microscope slide (preferably pond or tank water from which the fish was taken; tap or distilled water may destroy the parasites), a cover slip applied, and the preparation examined under the microscope (×40 magnification should be sufficient to visualize most parasites).
The second picture shows prepared gill, fin, and skin biopsies.
