General Parasitology and Helminthology: Life cycle

Life cycle

LIFE CYCLE

Adult mosquitoes ingest the microfilaria along with blood meal while feeding on the D/H.
Ingested microfilaria are first found in the stomach of mosquito then migrate to the malphighian tubule, where the further development occurs.
In about 4 days it will develop into a sausage form (i.e., 2nd stage larvae). The sausage form become "elongate sausage form" in nine days.
It feeds on the cells of malphighian tubule and enters into the haemocoel cavity.
From there, they migrate through the thorax and reach the mouthparts, where it becomes the infective stage.
The dogs get infected when the infected mosquitoes feeds on them. (by inoculation).
