Unnatural host in which parasites are accidentally lodged and transmission is through ingestion of infected paratenic host

Answer 16

Paratenic host

Anthropozooparasite

Question 26

Man is essential for the life cycle of the parasite

Answer 26

Enzoonoses

Question 27

It is unstable and unchangeable group and man is just accidentally involved

Answer 27

Question 28

This transmission is when no change in form or development occurs in the arthropod body

Answer 28

Mechanical transmission

Question 29

This transmission is when there is a change in form or development of the parasite or organism in the body of the arthropods

Answer 29

Biological transmission

Question 30

Give the three types of biological transmission

Answer 30

1. Cyclopropagative transmission
2. Cyclodevelopmental transmission
3. Propagative transmission

Question 31

Describe cyclopropagative transmission

Answer 31

Organism undergo cyclical changes or change in form as well as in number

Question 32

What is cyclo-developmental transmission

Answer 32

An organism undergo cyclic development changing form and size but there is no change in number in the body of the arthropod

Question 33

This biological transmission is when the organisms undergo multiplication in the arthropod but no cyclical development or change in form or size

Answer 33

Propagative transmission

Question 34

It occurs when the infection is through the next generation

Answer 34

Transovarian transmission or hereditary transmission

Question 35

Common case of transovarian transmission

Answer 35

Babesia species in ticks

Question 36

It is the transport of small parasites such as lice and mites by bigger parasites such as flies and mosquitoes

Answer 36

Phoresy or phoresis

Question 37

In cases of phoresis these eggs are deposited in the abdomen of mosquito so that it will hatch deposited or transferred in another host

Answer 37

Dermatobia hominis eggs

Give the factors that influence the degree of harm done by various parasites

Answer 38

Number of parasites present
Location of the parasites
Nature of their food
Movement of parasites
Age of the host

It is the presence of natural antibodies normally produced against bacteria and viruses

Answer 39

Natural immunity

Question 40

Products of antibodies due to infect on or exposure or pre-immunition

Answer 40

Acquired immunity

Question 41

Acquired resistance due to increase development of acquired immunity

Answer 41

Age resistance

Question 42

True or false: Older birds are more resistant than younger birds and this is what kind of immunity

Answer 42

True. True age immunity

Question 43

Give some factors that influence the resistance to parasites

Answer 43

Nutrition
Age of the host
Vitamins
General condition of the host
