Question

Write the scientific names of the two species of filarial worms causing filariasis.

Answer 1

Filariasis is also called elephantiasis.Elephantiasis or filariasis is caused by a filarial worm.

Complete step by step answer:
The filarial worm which causes the disease is Wuchereria.
The scientific names of the two species of filarial worms which cause filariasis are W. bancrofti and W. malayi.
It causes a slowly developing chronic inflammation of the organs in which they live for many years, usually the lymphatic vessels of the lower limbs.The genital organs are also affected.
The pathogen is transmitted to a healthy person through the bite of the female mosquito vectors.
It starts when mosquitoes are infected with the roundworm larvae bites. The tiny larvae survive in the bloodstream and grow. They finish maturing in the lymph system. They can live there for years and cause a lot of damage to your lymph system. This is what causes the swelling.
Lymphatic filariasis infection is asymptomatic and acute. The majority of infections are asymptomatic, showing no external signs of infection while contributing to transmission of the parasite. These asymptomatic infections can cause damage to the lymphatic system and the kidneys, and alter the whole body's immune system.

Note:
Ascaris is the common roundworm, and intestinal parasite causes ascariasis. Symptoms of these include internal bleeding, muscular pain,fever, anemia and blockage of intestinal passage. A healthy person acquires this disease through contaminated food and water.
