    Malaria is a serious and persistent threat to public health in many parts of Asia, including Bangladesh. The disease is caused by a parasite that is transmitted to humans through the bites of infected mosquitoes. In Bangladesh, around 90% of malaria cases are due to Plasmodium falciparum, and around 85% of cases occur in the malaria-endemic Southeast.

    There are several factors that contribute to the high incidence of malaria in Bangladesh. One factor is the presence of Anopheles mosquitoes, which are the primary vectors for transmitting the malaria parasite. Bangladesh has 34 Anopheles mosquito species. Another factor is the climate, which provides favorable conditions for the breeding of mosquitoes. Additionally, socioeconomic factors such as poverty, poor housing conditions, and lack of access to healthcare can increase the risk of malaria transmission.

    The life cycle of the malaria parasite involves two hosts: humans and female Anopheles mosquitoes. During a blood meal, a malaria-infected female Anopheles mosquito inoculates sporozoites into the human host. Sporozoites infect liver cells and mature into schizonts, which rupture and release merozoites. Merozoites then infect red blood cells, where they multiply and release more merozoites, continuing the cycle.

    Some of the merozoites develop into male and female gametocytes, which are taken up by a female Anopheles mosquito during a blood meal. In the mosquito’s gut, the gametocytes fuse to form zygotes, which develop into motile ookinetes that invade the mosquito’s midgut wall and develop into oocysts. The oocysts grow, rupture, and release sporozoites, which migrate to the mosquito’s salivary glands. When the mosquito takes another blood meal, it injects the sporozoites into a new human host, starting the cycle again.

    Post Kala-azar dermal leishmaniasis (PKDL) is a well-recognized complication of visceral leishmaniasis (VL) or kala-azar. It has been described since the beginning of the 20th century both in Asia and Africa, in areas where Leishmania donovani is the causative parasite.

symbiosis

    Dr Md shahriar kabir B H M S; MPH Enlightened dr.basuriwala

    symbiosis, any of several living arrangements between members of two different species, including mutualism, commensalism, and parasitism. Both positive (beneficial) and negative (unfavourable to harmful) associations are therefore included, and the members are called symbionts.

    There are three types of human parasites:

    1. Protozoa: Protozoa are single-celled organisms that can multiply in humans. These parasites can spread through contaminated food and water, person-to-person contact, and insect bites. Protozoa include Plasmodium malariae, which causes malaria infection, and Cryptosporidium, which is ingestible.

    2. Helminths: Helminths are parasitic worms that often root in a person’s digestive tract. These parasites cannot multiply or divide within a human body and eventually pass through a person’s stool. These include Ascaris lumbricoidesTrusted Source and hookwormTrusted Source parasites.

    3. Ectoparasites: Ectoparasites are small organisms that live on the outside of the body. These include ticks, fleas, and lice.

host

    Dr Md shahriar kabir B H M S; MPH Enlightened dr.basuriwala

    In biology and medicine, a host is a larger organism that harbours a smaller organism; whether a parasitic, a mutualistic, or a commensalist guest (symbiont). The guest is typically provided with nourishment and shelter.

    Protozoa are divided into four major groups based on the structure and the part involved in the locomotion:

    1. Mastigophora or Flagellated protozoans:
    They are parasites or free-living.
    They have flagella for locomotion
    Their body is covered by a cuticle or pellicle
    Freshwater forms have a contractile vacuole
    Reproduction is by binary fission (longitudinal division)
    Examples: Trypanosoma, Trichomonas, Giardia, Leishmania, etc.

    2. Sarcodina or Amoeboids:
    They live in the freshwater, sea or moist soil.
    The movement is by pseudopodia. They capture their prey by pseudopodia
    There is no definite shape and pellicle is absent
    The contractile vacuole is present in the amoeboids living in freshwater
    Reproduction is by binary fission and cyst formation
    Examples: Amoeba, Entamoeba, etc.

    3. Sporozoa or Sporozoans:
    They are endoparasitic.
    They don’t have any specialised organ for locomotion
    The pellicle is present, which has subpellicular microtubules, that help in movement
    Reproduction is by sporozoite formation
    Examples: Plasmodium, Myxidium, Nosema, Globidium, etc.

    4. Ciliophora or Ciliated protozoans:
    They are aquatic and move actively with the help of thousands of cilia.
    They have fixed shape due to covering of pellicle
    They may have tentacles, e.g. in the sub-class Suctoria
    Contractile vacuoles are present
    Some species have an organ for defence called trichocysts
    They move with the help of cilia and the movement of cilia also helps in taking food inside the gullet
    They reproduce by transverse division and also form cysts
    Examples: Paramecium, Vorticella, Balantidium, etc.

    A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites.
