Chapter 21: Helminth Parasites and Arthropod Vectors
1. What are the three major taxa for the parasitic worms we studied? 2. What are the distinguishing features of these taxa? 3. What is an exemplar of each taxon? How is it transmitted? What are potential complications? What is the geographical distribution? 4. Are there alternate hosts? If so, what are they? 5. What are the two taxa of arthropods that are involved in human/animal disease?
1. The three taxa of parasitic worms are
2. 1)Trematodes
2)Nematodes
3)Cestodes
3. the examples are
Spreads through contaminated food and water
The complications are pancreatitis,intestinal obstructions,defective assimilation and associated deficiency disorders
Commonly seen in the asian countries
Transmission is through contaminated food and water.The parasites penetrate human skin to enter the bloodstream and migrate to the liver, intestines and other organs.
The complications are GI bleeding, GI obstruction,hemmaturia,renal failure etc
geographical distribution is tropical and subtropical countries.
The transmission is through the contaminated food and water containing the ascaris eggs (orofecal transmisssion)
The major complications are intestinal obstruction,Ductal blockages and nutritional deficiencies
The disease has a worldwide distribution with a major share in the tropical and subtropical countries
