It lives in small intestine- jejunum part Involve two larval stages- Rhabiditi larva and Fillarial form Steps in Life cycle: Ancyclostoma duedenale head part comprises of Buccal Capsule and Copulatory spicules in case of male. Stage 1: Passage of eggs from infected host: The infected host releases eggs through feces in blastomere stage in environment. Stagec2: Development of eggs in soil: Eggs undergo further division forming larvae- Rhabiditi larva which is feeding one undergo molting then form Filariform larva. Stage 3: Entry of Filariform larva from environment to the host (man) through legs while walking on grass. Stage 4 : Entry of larva in blood circulation. It then enters the lungs then stomach finally migrate to small intestine. In intestine it attains functional maturity and develop to complete ancyclostoma. It is then resdy to copulate again and release the eggs t

The pathogens in vaccine are unable to cause disease but sufficient to stimulate antigen production. As a result the vaccinated person develop immunity without contacting with disease. The use of Vaccines for disease treatment is said to be vaccinotherapy. Principle of Vaccination VACCINE: It is a suspension or extract of germs that are weakened and injected upon injected to normal body provides active aquired immunity. Vaccines can be obtained by seperation of antigen from the infecting agent surface and then multiplying it with recombinant technology. PRINCIPLE: It is based on the principle of memmory cells property and production of B cells and
