Why is it important to know the life cycle of a parasite?
A detailed understanding of parasite life cycles facilitates development of strategies for control of parasites of medical and veterinary importance. Host species can be very restricted for some parasites, but for some parasites many host species can be infected.
How can parasite be controlled?
There are several methods through which biological control of parasites could be achieved, including the use of predators (such as arthropods, mites, flies, beetles, amphibians, fish, birds, rodents, etc.), parasites (parasitoids) and pathogens (such as fungi, bacteria, viruses and virus‐like particles, protozoa and …
What is a life cycle when referring to parasites?
Parasites have either a direct life cycle, in which they require only one. host, or an indirect cycle, in which one or more intermediate hosts are. required. An intermediate host is the one in which the young parasite. undergoes development leading to the stage which is infective to the final.
Why do parasites have complex life cycles?
Since fewer parasite stages are lost to mortality and more make it to the definitive host via trophic transmission, overall transmission rates increase. Both downward incorporation and upward incorporation are thought to have led to the evolution of complex life cycles for some parasite species.
What is the life cycle of malarial parasite?
The malaria parasite life cycle involves two hosts During a blood meal, a malaria-infected female Anopheles mosquito injects sporozoites into the human host, following which sporozoites infect liver cells and mature into schizonts to release merozoites.
What do you think is the best solution to stop the spread of parasites?
Avoiding parasitic infections – Drink clean, bottled water when traveling. – If you are pregnant, stay away from cat litter and feces. – Practice safe sex. – Wash your hands often, especially after contact with contaminated food, water, and feces.
Which parasite has the most complex life cycle?
Dicrocoelium dendriticum, commonly called the Lancet liver fluke, is a parasitic fluke that displays one of the most complex parasitic life cycles currently known. The Lancet liver fluke lives mainly in cows and sheep, but is also found in other herbivorous mammals and, in rare cases, has been known to infect humans.
What is the infective stage of malarial parasite?
Structure and Life Cycle The stage infective for humans is the uninucleate, lancet-shaped sporozoite (approximately 1 × 7 μm). Sporozoites are produced by sexual reproduction in the midgut of vector anopheline mosquitoes and migrate to the salivary gland.
