Identify the Different Forms of Protozoan Parasites

• Amastigotes are roundish to oval and measure 5 by 3 μm in size
• Promastigotes are 9 to 15 μm in length with a long slender body and a single free flagellum
• Epimastigotes are wider than promastigotes, measuring approximately 9 to 15 μm in length, with an undulating membrane forming into a free flagellum at the anterior end
• Trypomastigotes measure 12 to 35 μm long by 2 to 4 μm wide and may assume the shape of the letters C, S or U in stained blood films
• Trypomastigotes have a posteriorly located kinetoplast, a full body length undulating membrane, and a single large nucleus located anterior to the kinetoplast
• Amastigotes contain a nucleus, a basal body structure called a blepharoplast, and a small parabasal body
• The dotlike blepharoplast gives rise to and is attached to an axoneme in amastigotes
• The large single nucleus in promastigotes is located in or near the center of the long slender body, and the kinetoplast is located in the anterior end of the organism
• The large single nucleus in epimastigotes is located in the posterior end of the organism, and the kinetoplast is located anterior to the nucleus
• Kinetoplast is an umbrella term often used to refer to the blepharoplast and small parabasal body in amastigotes.
