MALARIA| Causes and prevention |life cycle of plasmodium | causative agent of malaria| Types of malaria|Symptoms of malaria| Female anopheles

 MALARIA:

       • Causative agent à Plasmodium (Protozoa)
                • P.vivex.
                •P.malaria.
               • P.falciparum à
      • Responsible for malignant malaria
      • most serious and can even be fatal.

      • Plasmodium enter the human body à as SPOROZOITES form(infectious form) through the bite of female anopheles.



      • Plasmodium multiplies in liver cells à then attack the RBCs and resulting the

rupture of RBCs .
      • Rupture of RBC associated with release of a toxic substance called HEMOZOIN

à Responsible for chill, high fever recurring every three to four days. 

      • Asexual phase à completed in liver cells and RBCs of human.
      • Gametocytes of plasmodium à develops in RBCs of human.
      • When a anopheles bite the infected person, the parasite enters the mosquito 
body where sexual cycle is completed that is fertilization and further development take place in mosquito’s gut.
      • In mosquito, parasite multiply and form sporozoites .
      • These sporozoites are stored in the salivary gland of mosquito from where they 
will infect another human through biting of mosquito.



• Most important control measure - eliminate and control the vector and their 
breeding places. 

         Ø Gambusia fish eat the larva of mosquitoes. 
         Ø Avoid the stagnation of water. 
         Ø Regular cleaning of breeding place of mosquito like cooler, aquarium and pot of 
water plants etc.
         Ø Spray of insecticides.
         Ø Chickengunya and dengue are also transmitted by Aedes mosquitoes.

IMMUNITY:

Image
IMMUNITY:   • The ability of the host to fight the disease-causing organisms,   • conferred by the immune system.   .Immunity is of two types:   • Innate immunity   • Acquired immunity.  Innate immunity  • Non-specific type of defence,   • Present at the time of birth.   .Innate immunity is accomplished by providing different types of barriers to the entry of the foreign agents into our body.   • Innate immunity consists of four types of barriers.  These are —         • Physical barriers:                  Ø Skin                   Ø Mucus coating of the epithelium lining          • Physiological barriers:                  Ø Acid in the stomach,                  Ø saliv...

VACCINATION | small pox variola vaccine |hepatitis-B vaccine |vaccine

Image
 VACCINATION       • In vaccination, a preparation of antigenic proteins of pathogen or inactivated/weakened pathogen (vaccine) are introduced into the body.       • The antibodies produced in the body against these antigens would neutralise the pathogenic agents during actual infection.                • The vaccines also generate memory – B and T-cells that recognise the pathogen quickly on subsequent exposure and kill the invaders with a massive production of antibodies.         Production of large scale of vaccine become possible through DNA recombinant technology which allowed the production of antigenic polypeptide(vaccine) in bacteria and yeast.     Hepatitis B vaccine is produced from yeast through DNA recombination technology for large scale immunisation.
