Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Expert Solution & Answer

Summary Introduction

To determine: The group of children who were the most attractive to mosquitoes.

Introduction: Plasmodium is one among the genus of unicellular eukaryotes that are obligate parasites of vertebrates and insects. It infects humans and is responsible for most malarial infections. It is transmitted through the bite of the female Anopheles mosquito. The life cycle involves the mosquito and the human as a host. During the blood meal, the malaria-infected mosquito inoculates sporozoites into the human host. The sporozoite infects the liver cells and matures into schizonts that rupture and releases the merozoites.

Explanation of Solution

In this study, the groups of children who have gametocytes in their blood were more attractive to the mosquitoes. Gametocytes that arise from the erythrocytic asexual stage are responsible for the transmission of the parasite from the mammalian host to the mosquito. The graph shows the number of mosquitoes in the y-axis, and the children with gametocytes, children with asexual stage, and uninfected children in the x-axis. The graph shows that children with gametocytes of Plasmodium are more attracted to mosquitoes.

Conclusion

The children with gametocytes present in their blood are most attractive to mosquitoes.
