The definitive host for Toxoplasma gondii is __________.
a. humans
b. cats
c. birds
d. mosquitoes
Guida verificata passo dopo passo1
Understand the concept of a definitive host: In parasitology, the definitive host is the organism in which a parasite reaches sexual maturity and reproduces sexually.
Recall the life cycle of Toxoplasma gondii: This parasite has a complex life cycle involving multiple hosts, but sexual reproduction occurs only in one specific host.
Identify the host where Toxoplasma gondii undergoes sexual reproduction: This is the key to determining the definitive host.
Review the options given: humans, cats, birds, and mosquitoes, and consider which of these is known to support the sexual phase of Toxoplasma gondii.
Conclude that the definitive host is the organism where the parasite completes its sexual cycle, which is cats in the case of Toxoplasma gondii.

Role of Cats in Toxoplasma gondii Transmission
Cats are the definitive hosts for Toxoplasma gondii, where the parasite completes sexual reproduction. They shed oocysts in their feces, which can infect other animals and humans, making cats central to the parasite's transmission.
