65
Q

A veterinarian suspects that a trypanosome from cattle is undergoing asexual reproduction upon examination of the Giemsa-stained blood smear. Is the observation correct?
a. No, because trypomastigotes are found in enterocytes
b. No, because trypanosomes do not infect cattle
c. Yes, because trypomastigotes found in the blood can undergo binary fission
d. Yes, because epimastigotes found in the blood can undergo binary fission

A

Yes, because trypomastigotes found in the blood can undergo binary fission

66
Q

A veterinarian diagnose trypanosomiasis in a buffalo based on early trophozoite stages inside the erythrocytes upon examination of the Giemsa-stained blood smear. Is the observation correct?
a.No, it is likely caused by an apicomplexan parasite
b.No. it is likely caused by a coccidian parasite
c.Yes, buffalo can be infected with Trypanosoma evansi
d.Yes, trypanosomes are intra-erythrocytic parasites

A

No, it is likely caused by an apicomplexan parasite

Trypomastigotes of Trypanosoma evansi are extra-cellular parasites (i.e., found outside RBCs and WBCs in a Giemsa-stained blood smear). Blood smear from a buffalo with parasite’s early trophozoite stages inside the RBCs is likely associated with Plasmodium bubalis.

67
Q

How will you prevent equine trypanosomiasis in Leyte, Philippines?
a.By preventing tabanids from feeding on horses
b.By preventing tsetse fly from feeding on horses
c.By administering albendazole to horses

79
Q

Which of the following protozoan parasite you cannot not find an undulating membrane when examined under a light microscope
a. Leishmania infantum
b. Trypanosoma evansi
c. Trypanosoma cruzi
d. Tritrichomonas blagburni

A

Leishmania infantum

Trypanosomes and trichomonads feature an undulating membrane, a fin-like extension typically associated with the flagellum. The presence of an undulating membrane improves the parasite’s motility in viscous fluids, such as blood.

80
