Question

Wuchereria bancrofti is transmitted by :a)Tse-Tse flyb)Sand flyc)Anophelesd)CulexCorrect answer is option 'D'. Can you explain this answer?

Answer

Tsetse fly - sleeping sickness
sand fly - leishmaniasis
anopheles - malaria
culex - filariasis or elephantiasis caused by wuchereria bancrofti and wuchereria malayi

Answer

Culex mosquito is the vector of wuchreria Bancroft or malayi these causes elephantiasis

Answer

Wuchereria bancrofti is a human parasitic roundworm that is the major cause of lymphatic filariasis. It is one of the three parasitic worms, together with Brugia malayi and B. timori, that infect the lymphatic system to cause lymphatic filariasis. These filarialworms are spread by a variety of mosquito vector species.

Answer

Culex is style or say name of mosquito which transmits disease called wucheria bancrofti

Answer

Transmission of Wuchereria bancrofti

Wuchereria bancrofti is a parasitic worm that causes lymphatic filariasis, a neglected tropical disease. It is commonly transmitted to humans through the bite of infected mosquitoes. The correct answer to the question is option 'd', Culex mosquitoes, as they are the main vectors responsible for transmitting this parasite.

Explanation:

1. Lymphatic Filariasis:
Lymphatic filariasis is a parasitic disease caused by three species of thread-like nematode worms, including Wuchereria bancrofti. This disease is prevalent in tropical and subtropical regions, particularly in Africa, Asia, the Western Pacific, and parts of the Caribbean and South America.

2. Vector:
A vector is an organism that transmits a pathogen (parasite) from one host to another. In the case of Wuchereria bancrofti, mosquitoes serve as the vectors. When an infected mosquito bites a person, the microscopic larvae of the parasite (microfilariae) enter the person's bloodstream.

3. Transmission:
The transmission cycle of Wuchereria bancrofti involves several steps, as described below:

- Biting Mosquito: The primary vector for Wuchereria bancrofti is the Culex mosquito, specifically Culex quinquefasciatus. This mosquito species is widespread and commonly found in urban and rural areas.

- Infected Mosquito: Female mosquitoes become infected with Wuchereria bancrofti when they feed on the blood of an infected human. The microscopic larvae (microfilariae) present in the blood enter the mosquito's body.

- Maturation: Inside the mosquito, the microfilariae mature into infective larvae over a period of 10 to 14 days.

- Bite and Transmission: The infected mosquito then bites a healthy individual, introducing the infective larvae into the person's bloodstream. The larvae migrate to the lymphatic system, where they develop into adult worms over several months.

- Lymphatic System: Once inside the lymphatic system, the adult worms can cause inflammation and damage to the lymphatic vessels, leading to chronic lymphatic filariasis.

Conclusion:

In conclusion, Wuchereria bancrofti, the causative agent of lymphatic filariasis, is primarily transmitted to humans through the bite of infected mosquitoes. Among the potential mosquito vectors, the Culex species, particularly Culex quinquefasciatus, is responsible for transmitting this parasite. Understanding the transmission cycle is crucial for implementing effective control measures to prevent the spread of lymphatic filariasis.
