10 Questions
What is the main difference between biologic vectors and mechanical vectors?
Biologic vectors carry parasites only after development within the vector organism, while mechanical vectors transport the parasite directly to another host.
How does the Aedes mosquito transmit parasites to another susceptible host?
After the parasite has undergone development within the Aedes mosquito and reached the L3 stage.
Which of the following correctly describes mechanical vectors?
They transport parasites directly to another host without development within the vector organism.
What type of organisms can act as mechanical vectors for transmitting enteric organisms to humans?
Flies and cockroaches that feed on fecal material.
Which statement best describes a parasite?
An organism that grows, feeds, and shelters on or in a different organism without contributing to the survival of the host.
'Phoretic vectors' are most similar in function to which of the following?
'Hitchhikers' that carry parasites on their bodies without being affected by them.
What happens when an Aedes mosquito sucks blood from a filariasis patient?
The parasite undergoes several stages of development from L1 to L3 before transmission occurs.
How do flies and cockroaches contribute to the transmission of enteric organisms to humans?
By feeding on contaminated material and carrying enteric organisms on their bodies.
'Biologic vectors' and 'mechanical vectors' can be distinguished by which factor?
'Biologic vectors' only transmit parasites after development within themselves, while 'mechanical vectors' transport them directly.
