Do Male Mosquitoes Bite?

July 11, 2012 By Malaria Q&A Leave a Comment

QUESTION Why do male mosquitoes not bites humans? ANSWER Male mosquitoes do not possess the right kind of feeding apparatus to feed on humans—they only feed on nectar. This is because they do not need to produce eggs, which require lots of energy and protein to make, and so the female mosquitoes need a more comprehensive food source than just nectar when they are egg-laying, such as … [Read more...]

Malaria: Mode of Transmission

June 27, 2012 By Malaria Q&A Leave a Comment

QUESTION What is the mode of transmission of Malaria? ANSWER Malaria is transmitted normally via the bite of an infected mosquito. These mosquitoes, always female and of the genus Anopheles, carry malaria parasites in their salivary glands. The parasites, at this part of their life cycle known as sporozoites, are introduced into the host's blood when the mosquito takes a blood meal. From … [Read more...]

Structure and Size of Malaria Mosquito

June 6, 2012 By Malaria Q&A Leave a Comment

QUESTION What is the structure and size of the mosquito? ANSWER The mosquitoes that transmit human malaria belong to the genus Anopheles. As such, they follow the general body plan structure of a flying insect—three segments (head, thorax and abdomen), three pairs of legs and two pairs of wings. Anopheles females have modified mouthparts that allow them to feed on blood, by … [Read more...]

QUESTION Which are malaria hosts and how does malaria have an effect on one of them? ANSWER The parasite which causes malaria (called Plasmodium) requires two different hosts—a vertebrate intermediate host, such as a human, and an insect definitive host, also known as the vector. For the types of malaria which infect humans and other mammals, the vector is always a mosquito of the … [Read more...]

Causes of Malaria

June 5, 2012 By Malaria Q&A Leave a Comment

QUESTION What are the causes of malaria? ANSWER Malaria is caused by a parasite called Plasmodium, which is transmitted via the bites of infected mosquitoes. In the human body, the parasites multiply in the liver, and then infect red blood cells. Usually, people get malaria by being bitten by an infective female Anopheles mosquito.  Only Anopheles mosquitoes can transmit malaria and … [Read more...]

Classification of Malaria

June 4, 2012 By Malaria Q&A Leave a Comment

QUESTION Classification of malaria ANSWER Malaria is caused by a single celled protist of the genus Plasmodium. This genus is part of a Phylum of single-celled protist organisms called Apicomplexa. The Apicomplexans mostly posses an organ called an apicoplast, which is part of an apical structure designed to aid entry into a host cell. The Apicomplexa is split into two Classes, of … [Read more...]

Malaria Socio-Economic Issues

June 1, 2012 By Malaria Q&A Leave a Comment

QUESTION What are the socio-economic issues on the spread of malaria? ANSWER Malaria transmission requires the presence of Anopheles mosquitoes; as such, conditions which favor the growth and persistence of these mosquitoes will also be hotspots for malaria transmission, provided the climate is also sufficiently warm for the development of the parasite within the mosquito. Rural areas … [Read more...]
