Disease Vectors and Pathogens

Wuchereria bancrofti is a parasitic roundworm that causes lymphatic filariasis, which can lead to the condition known as elephantiasis.

The sand fly is the primary vector for the protozoan parasite Leishmania, which causes Leishmaniasis. Malaria is spread by Anopheles mosquitoes, and Dengue/Chikungunya are spread by Aedes mosquitoes.

Ronald Ross discovered that the malaria parasite is transmitted by the Anopheles mosquito in 1897 and published his findings in 1898. This is a landmark date in medical history.

Bite of dog causes rabies as bite of mosquito causes malaria.

Malaria is a type of disease as spear is a type of weapon.

Phleobotmus or sand fly spreads kala azar.

Filaria (lymphatic filariasis) is a parasitic disease caused by microscopic, thread-like worms that infect the lymph system.

The Widal test is a serological test used to detect antibodies against Salmonella typhi, the bacteria that causes typhoid fever.

 Taenia solium is the tapeworm which causes cysticercosis,a pork infection.

Holoparasites or obligate parasites cannot complete their life cycle without harming the host. 

Only female mosquitoes bite humans because they require the protein found in blood to develop their eggs. Male mosquitoes feed exclusively on plant nectar.

Mosquitoes are the most common vectors for many diseases, including malaria, dengue, and Zika. They are highly efficient at transmitting pathogens between human hosts.

Malaria is caused by Plasmodium parasites, not a virus. However, in the context of the life cycle of the malaria parasite, it travels to the liver first to multiply before infecting red blood cells.

Malaria is transmitted to humans through the bite of an infected female Anopheles mosquito. The parasite is injected into the bloodstream during the bite.
