Q
Which of the following organisms is known to be a blood sucker of the abomasum in sheep and goats?
- Fasciola gigantica
- Ostertagia ostertagii
- Strongyloides spp
- Haemonchus contortus
A
Answer: Haemonchus contortus
Explanation
The correct answer is Haemonchus contortus.
Ostertagia is not considered a blood sucker; instead this organism invades the abomasal wall.
Strongyloides spp are intestinal threadworms that migrate to the intestines by first penetrating the oral mucosa or the skin, entering the bloodstream, and then heading for the heart. Afterward, they travel to the lungs and trachea, where they are swallowed and enter the intestines. Fasciola gigantica is a liver fluke.
