A parasite is considered a vector when it actively transmits pathogens from one host to another, facilitating the spread of disease. In this context, the parasite typically carries the infectious agent—such as a virus, bacterium, or protozoan—while also benefiting from its relationship with the host, often without causing immediate harm to the vector itself. Examples include mosquitoes that transmit malaria or dengue fever. Thus, the distinction lies in the parasite's role in disease transmission rather than merely being a host.
A vector.
The Anopheles mosquito is the vector that transmits the malaria parasite Plasmodium vivax into the bloodstream. When an infected mosquito bites a person, it injects the parasite into the bloodstream, where it multiplies and causes malaria.
vector is usually is the arthropodes carrying the parasites such as mosquitoes.
The vector for Plasmodium, the parasite that causes malaria, is the female Anopheles mosquito. These mosquitoes can transmit the parasite to humans through their bites during blood meals.
This is very good question indeed. No such study is probably conducted. But you can do a logical guess work for the same. Most of the vectors carry the disease life long. That means the microorganism is living in the body of the vector. So it is not causing serious illness to the vector. But the micro organism has been deriving the nutrition from the body of the vector only. So the vector is also probably suffering in the process. A good parasite will neither kill the man nor the vector but will like to survive, without much disturbing both of them. A very good parasite may help the host and then this process is called as symbiosis. That means peaceful coexistence!
A virus is considered a parasite because it attaches to a cell and kills it.
A heartworm is a parasite that is found in dogs. Someone who allows another person to do all the work can be considered a parasite.
Yes, a mosquito is considered a parasite because it feeds on the blood of its host, often causing harm or discomfort.
No, time is not considered a vector in physics. It is a scalar quantity that represents the progression of events.
The vector of transmission for leishmaniasis is typically a sandfly, which becomes infected by biting an infected animal or person. The sandfly then transmits the parasite to a new host through its bite.
A vector is simply an organisms which serves to carry or transport a disease, for example the mosquito (an arthropod) carrying the protozoan malaria parasite. Hence a non-arthropod vector would be a vector outside phylum Arthropoda, for instance, a dog (a vertebrate, from phylum Chordata) carrying the rabies virus.
