The names of two parasites that are transmitted in the cyst form. Introduction: Most protozoa are recognised by their motile feeding stage called trophozoite . Many protozoa have a resting stage called cyst when environmental conditions are unfavourable for growth and feeding. The cyst stage is characterized by a thick cuticle wall above the cell membrane that makes the organism resistant to heat, dryness and chemicals. Many pathogenic protozoa are transmitted to their host in their cyst form.

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

a. What are the primary functions of the trophozoite and the cyst inthe life cycle?b. In which diseases is a cyst stage an important part of the infectioncycle?

A 35-year old man who is originally from Palawan, Philippines traveled to South America to live with his partner. 3 days after the man stayed in abroad, he went to a hospital and complained of frequent abdominal cramping and diarrhea. According to the patient, he had no sexual contact with his partner and had not eaten any spoiled food that might cause his diarrhea. His physician ordered a stool examination and the results were normal and no cyst/ trophozoite of a parasite are seen. 1. What possible actions or additional laboratory tests are needed in this case to rule out the most likely diagnosis if the patient is infected with a parasite? Why?

What might be the possible reason why there are no cysts/trophozoites seen in the stool? Is there a discrepancy? B. What possible actions or additional laboratory tests are needed in this case to rule out the most likely diagnosis if the patient is infected with a parasite? Why? C. Is this caused by a parasitic infection or no? If you were the medical laboratory scientist, how you will handle this situation?
