What is the feeding stage of plasmodium?
The feeding stage of Plasmodium, the parasite responsible for malaria, occurs in the form of merozoites, which are released from the liver into the bloodstream after the liver stage of infection. These merozoites invade red blood cells, where they mature and reproduce asexually, leading to the destruction of the host cells and the release of more merozoites. This cycle of invasion, reproduction, and destruction is responsible for the symptoms of malaria. Additionally, some merozoites develop into gametocytes, which can be taken up by a mosquito, continuing the life cycle of Plasmodium.
Why plasmodium first attack on liver cells?
Plasmodium, the parasite responsible for malaria, first attacks liver cells because this is the stage of its lifecycle where it undergoes asexual reproduction. After being transmitted to humans through mosquito bites, the parasite travels to the liver, where it can multiply rapidly and form thousands of merozoites. This initial infection in the liver allows the parasite to evade the host's immune response, as liver cells provide a sheltered environment for replication before releasing the merozoites into the bloodstream, leading to the symptoms of malaria.
Describe the life cycle of plasmodium in mosquito?
plasmodiumthey can finish their growth for about 7 to 10 days at 20C or 68F.Their life cycle proceeds in two hosts. They are 1) Mosquito serves as primary host2) Man serves as secondary host3) Monkey serves as reservoir host
What is the second stage of Plasmodium called?
The first stage of Plasmodium is called Sporozoite. Which lives in mosquitoes and is injected into humans. The second stage of Plasmodium is called Merozoite.
Describe the developmental stages of the malarial parasite during sporogamy and schizogony?
SporogonyThe Anopheles mosquito ingests malarial parasites when it feeds on an infected human. In the mosquito's stomach, the parasites move to the gut wall, where they reproduce asexually through the process of sporogony, and produce an oocyst, or spore. These oocysts eventually burst, releasing sporozoites that travel through the mosquito's body to its salivary glands, and finally to its central salivary duct.SporozoitesWhen a carrier mosquito drinks human blood, the malarial sporozoites travel through its saliva to the host's blood stream, and quickly make their way to the liver's functional cells. The parasites can also infect red blood cells, causing fever, anemia and -- in some cases -- death.SchizogonySchizogony is a form of asexual reproduction in which the multiple fission of sporozoites produces merozoites that can reproduce sexually or asexually. This process often begins as soon as the parasites enter their vertebrate host. For example, Plasmodium falciparum and P. malariae begin reproducing immediately. However, P. ovale and P. vivax may delay reproduction, by forming hypnozoites that remain dormant in the liver cells. P. vivax hypnozoites can have a dormancy of up to 10 months, whereas P. falciparum and P. malariae do not create hypnozoites at all.MerozoitesPre-erythrocytic schizogony occurs in the host's liver cells before the parasite invades red blood cells (erythrocytes). During this phase, each sporozoite produces multiple merozoites, which consist of a single nucleus encased in a narrow cytoplasmic ring. Each P. ovale sporozoite produces 15,000 merozoites. P. vivax produces 10,000, P. falciparum produces 40,000 and P. malariae produces 2,000. Merozoites typically invade red blood cells within two minutes of life.

Which stage of plasmodium is infective to man?
The infective stage of Plasmodium that affects humans is the sporozoite. This form is introduced into the bloodstream through the bite of an infected female Anopheles mosquito. Once in the human host, sporozoites travel to the liver, where they multiply and eventually lead to the release of merozoites into the bloodstream, causing malaria.

Where do sporozoites develop into merozoites?
Sporozoites develop into merozoites in the liver of the host organism, specifically within liver cells known as hepatocytes. After sporozoites are injected into the bloodstream by a mosquito, they migrate to the liver, where they undergo asexual reproduction through a process called schizogony, resulting in the formation of merozoites. These merozoites are then released back into the bloodstream, where they can infect red blood cells.
What is the second stage of Plasmodium called?
The first stage of Plasmodium is called Sporozoite. Which lives in mosquitoes and is injected into humans. The second stage of Plasmodium is called Merozoite.
What parasitic sporazoan causes malaria?
Plasmodium vivax causes 8 out of 10 cases of malaria. Fortunately this form of malaria is usually not lethal.
Types of maleria?
There are five types of malaria. The types are plasmodium vivax, plasmodium malariae, plasmodium ovale, plasmodium falciparum, and plasmodium knowlesi.
What are the four species of plasmodium that cause malaria?
You have four species of Plasmodium which causes malaria in humans. They are Plasmodium vivax, P. falciparum, P. ovale and P. malariae.
