Explanation
Sporozoites represent the infective forms of malarial parasites. A healthy person acquires infection, when a female Anopheles mosquito, containing sporozoites, bites the person for sucking his blood. The mosquito punctures the host's skin by its proboscis and first introduces some saliva into the bloodstream. Along with saliva, thousands of sporozoites are inoculated in the host. The motile zygote then undergoes further development in the mosquito's gut to produce sporozoites, which migrate to the mosquito's salivary glands.
