The Flagellates A. List the classification of the following flagellates - Giardia lamblia and Trypanosoma brucei. B. Draw Giardia lamblia cysts and trophozoites. Label which is which. C. Draw Giardia intestinalis vegetative stage. D. Draw Trypanosoma brucei. 1. Give the pathological conditions these 2 flagellates cause. 2. If the average diameter of the mammalian red blood cell is 7.5 microns, what do you estimate the length of Trypanosoma brucei to be? 3. How do these organisms move? The Ciliates A. List the classification of Balantidium coli. Draw, identify and label the nucleus, cilia and any other structures you can identify in Balantidium coli. 1. Is conjugation sexual reproduction or asexual reproduction? Describe what happens during conjugation. 2. What pathological condition does this protozoa cause? The Sporozoans A. List the Kingdom of sporozoans according to your notes. B. Draw Eimeria stiedae and Eimeria tenella. Are they morphologically different? How would you tell them apart. C. Draw Plasmodium falciparum, Plasmodium vivax, and Plasmodium malariae. C. Answer the following question 1. Are various Plasmodium spp. morphologically different? 2. What are pathological conditions do they cause? 3. Describe the life cycle of a NAMED Plasmodium. You pick the one you want to do. The life cycle has to be detailed. You may draw a diagram but do not cut and paste one.

Drag the labels to complete each of the sentences that describe the progression of malaria. Malaria is caused by protozoans in the genus Plasmodium, with five species largely responsible for the disease in humans. The life cycle of the parasite can be divided into two stages; the ________ phase that takes place in humans and the ________ phase, which takes place in the ________. The asexual phase begins when the human is bitten by an Anopheles mosquito, injecting the ________ into the capillaries along with an anticoagulant. The cells circulate and enter the liver where they undergo ________; a form of asexual division producing numerous ________ within the hepatocytes. When the liver cell ruptures, thousands of merozoites enter the circulation where they infect erythrocytes and convert to ________. Lysis of erythrocytes releases more merozoites, and this ________ phase is responsible for the synchronous symptoms seen in the infected host. The Plasmodium life cycle cannot continue in the human, and the oocyte pass back into the mosquito when it feeds on infected blood. mosquito Plasmodium sporozoites trophozoites erythrocytic sexual gametocytes merozoites lymphocytic schizogony asexual oocyte
Which life cycle is indicated in the figure? (a) Amocba (b) Plasmodium (c) Paramecium (d) Filarial parasite
