Kala-azar a visceral leishmaniasis is a parasitic disease caused by Protozoa of the Leishmania genus. The insect vectors are species of sandfly of the genus Phlebotomus.
The life cycle of Ascaris lumbricoides involves a single host, that is, man. The egg fertilised eggs passed with the faeces develop into a rhabditiform larva in the soil which then transforms into egg containing the second stage which is hence, infective to man.
Encephalitis or inflammation of brain results either from a viral infection or when the body's own immune system mistakenly affects brain tissue (auto immune encephalitis).
Sporogony is a major phase of the life cycle of Plasmodium, where there encysted zygote undergoes multiple division, giming rise to the sporozoites.
