The Anopheles gambiae complex consists of at least seven morphologically indistinguishable species of mosquitoes in the genus Anopheles. The complex was recognised in the 1960s and includes the most important vectors of malaria in sub-Saharan Africa, particularly of the most dangerous malaria parasite, Plasmodium falciparum. [2]
Anopheles (/ ə ˈ n ɒ f ɪ l iː z /) is a genus of mosquito first described by the German entomologist J. W. Meigen in 1818, and are known as nail mosquitoes and marsh mosquitoes. [1] Many such mosquitoes are vectors of the parasite Plasmodium , a genus of protozoans that cause malaria in birds , reptiles , and mammals , including humans.
This mosquito is a vector of malaria, and mosquito control is an effective way of reducing its incidence. Methods used to prevent malaria include medications, mosquito elimination and the prevention of bites. As of 2023, there are two malaria vaccines, approved for use in children by the WHO: RTS,S and R21.
Human malaria is transmitted only by females of the genus Anopheles. Of the approximately 430 Anopheles species, while over 100 are known to be able to transmit malaria to humans, only 30–40 commonly do so in nature. Mosquitoes in other genera can transmit different diseases, such as yellow fever and dengue for species in the genus Aedes.
Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms. Either via their bite, as in the case of malaria spread by mosquitoes, or via their faeces, as in the case of Chagas' Disease spread by Triatoma bugs or epidemic typhus spread by human body lice. Many invertebrates are responsible for transmitting diseases.
There are very few winners in the climate crisis, but scientists are pretty sure there’s going to be at least one: Mosquitoes. The mosquito era: As the world warms, these insects are thriving ...
Plasmodium vivax is a protozoal parasite and a human pathogen.This parasite is the most frequent and widely distributed cause of recurring malaria. [2] Although it is less virulent than Plasmodium falciparum, the deadliest of the five human malaria parasites, P. vivax malaria infections can lead to severe disease and death, often due to splenomegaly (a pathologically enlarged spleen).
Cases of malaria are increasing each year and mosquito nets are an important tool that help protect against the disease. However, there will continue to be downside if they are handed out without ...
