Which mode of transmission is followed in transmission of malaria by female anopheles cyclo- propagative propagative cyclo – developmental vehicle – born

The mode of transmission of malaria by the female Anopheles mosquito is cyclo-propagative. Here's a step-by-step explanation:

1. The female Anopheles mosquito is the primary vector for malaria transmission. It becomes infected by feeding on a person who has malaria.

2. Once the mosquito is infected, the malaria parasites undergo a series of developmental stages within the mosquito's body. This is the "cyclo" part of cyclo-propagative, referring to the life cycle of the parasite.

3. The "propagative" part refers to the multiplication of the parasites within the mosquito. The parasites reproduce and increase in number.

4. When the mosquito feeds on a human, the parasites are transmitted from the mosquito's salivary glands into the human bloodstream. This is how the disease is spread.

5. The term "vehicle-born" is not typically used in the context of malaria transmission. Malaria is not spread through vehicles or any form of inanimate objects. It is a vector-borne disease, meaning it is transmitted through a living organism (in this case, the mosquito).

6. The term "cyclo-developmental" is also not typically used in the context of malaria transmission. However, it could potentially refer to the developmental stages that the parasites go through within the mosquito's body.
