QUESTION What is the life cycle of malaria? ANSWER The life cycle of malaria is complex, involving a definitive host, or vector, which for human malaria is a mosquito of the genus Anopheles, and also a human host. Inside both, the malaria parasite undergoes several different transformations and reproductive cycles, which are detailed in the schematic below. You may also view a video of … [Read more...]
Malaria Host Range
QUESTION What are the Host range? ANSWER Malaria is caused by a parasite, of the genus Plasmodium, which requires two organisms for the completion of its life cycle—an insect, which is usually referred to as the "vector," in which sexual reproduction occurs, and a vertebrate "host," in which asexual multiplication occurs. Different species of Plasmodium infects a large range of … [Read more...]
How Long Does it Take for Malaria to Affect the Body?
QUESTION How long does malaria take to actually affect you? ANSWER When you are bitten by a mosquito that is infected with the parasites that cause malaria, some of the parasites enter your blood stream in the mosquito's saliva. After that, it will take at least one week, and usually between two and four weeks, before you start to feel the symptoms of the disease. This is because the … [Read more...]
Malaria Life Cycle
QUESTION What is the life cycle of malaria? ANSWER Malaria is caused by a single celled organism in the genus Plasmodium. Five species of Plasmodium infect humans, but all follow a very similar life cycle, including two separate cycles of asexual reproduction in the human host (one in the liver, called the exo-erythrocytic cycle, and one in the blood, and specifically inside red blood … [Read more...]
Malaria Effect on Host
QUESTION What is the effect of malaria on host? ANSWER In the human host, malaria can often make a person very sick, though the exact symptoms and severity of the disease depends on the type of malaria (five different kinds of malaria infect humans). Many people will have a high fever, chills, nausea and body aches. In a symptom very typical of malaria, a patient will experience cyclical … [Read more...]
Is Malaria a Mosquito STD?
QUESTION Is Malaria a type of STD for mosquitoes? ANSWER No. Mosquitoes pick up the malaria parasite from feeding on the blood of infected humans. Since only female mosquitoes feed on blood (the males feed on nectar), male mosquitoes never get infected with the malaria parasite. The life cycle of malaria in the mosquito is also completely different than in humans, and mosquitoes have a … [Read more...]
Malaria Infectious?
QUESTION Is malaria infectious? ANSWER Yes, malaria is considered an infectious disease, though it is very rarely transmitted directly between people, and virtually all of the time must be transmitted via the bite of a mosquito (of the genus Anopheles). Because part of the life cycle of malaria occurs in red blood cells in the human host, if sufficient amounts of blood are shared … [Read more...]
Life Cycle of Malaria
QUESTION Why does the malaria parasite first enter the liver? ANSWER The malaria parasite enters the liver in order to transform from a sporozoite (which can infect liver cells) to a merozoite, which is capable of infecting red blood cells. Both stages also include a proliferation step, but in the blood, the merozoites are also able to differentiate into gametocytes, which are then taken … [Read more...]
Malaria Mosquito Eggs
QUESTION Where do Anopheles mosquito lay their eggs? ANSWER Female Anopheles mosquitoes lay their eggs in standing, often stagnant, pools of fresh water. These larvae can be identified in ponds and puddles because unlike other mosquito larvae, they position themselves parallel with the surface of the water, allowing them to breathe air despite not having a respiratory siphon (instead, … [Read more...]
Malaria Parasites Classification
QUESTION Where are malaria parasites classified? ANSWER The parasite that causes malaria comes from the genus Plasmodium, which 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...]
