Questions: Question 13 Match the following parasitology terms to their respective definitions: Vector [ Choose ] Definitive host [ Choose ] Infected host that makes a parasite available for transmission to other host Intermediate host Range of hosts in which a parasite can mature Reservoir host Organism tha transfers a parasite to a new host Host specificity Host in which the parasite reproduces sexually Host in which the parasite is present during some developmental stage other than sexual reproduction

The answer is as follows:

1. Vector: Organism that transfers a parasite to a new host
2. Definitive host: Host in which the parasite reproduces sexually
3. Intermediate host: Host in which the parasite is present during some developmental stage other than sexual reproduction
4. Reservoir host: Infected host that makes a parasite available for transmission to other hosts
5. Host specificity: Range of hosts in which a parasite can mature

Explanation:

• A vector is an organism, often an insect, that transmits a parasite from one host to another.
• The definitive host is where the parasite undergoes sexual reproduction.
• The intermediate host is where the parasite undergoes development but not sexual reproduction.
• The reservoir host is an infected host that harbors the parasite and can transmit it to other hosts.
• Host specificity refers to the range of different hosts that a parasite can infect and mature within.
