Question

Suggest a suitable word for the following statements.
Agent which spreads pathogens from one place to another.

Answer 1

Pathogens are the infectious microorganisms can be of unique kinds such as bacteria, viruses, fungi, protozoa, etc. They are the causative agents that causes diseases. They are transmitted through the external agents which carry these pathogens. For example, female Anopheles carries malarial parasites.

Complete answer:
The five foremost sorts of infectious agents are as follows-bacteria, viruses, fungi, protozoa, and helminths. These agents can cause emerging and re-emerging diseases in the host organisms. Infectious agents or pathogens can transmit disease through more than a few transmission methods such as direct and indirect methods. In direct contact, an individual is infected when they come in contact with the reservoir. While in indirect contact, pathogens are transmitted from inanimate objects.

These infectious pathogens require an agent which helps in taking the organism to the host. For example- female Anopheles is the carrier for malarial parasite Plasmodium vivax to the humans. These agents are known as vectors which act as a vehicle to carry the causative pathogen to the host.
Some example- of vector borne diseases are dengue transmitted through Aedes mosquito, filaria caused by a nematode and is transmitted through mosquitoes, Typhoid transmitted through cockroaches.

The Agents that transmit disease from one place to another are known as vectors.

Note: Bacteria such as Cyanobacterium, Streptococcus, Salmonella typhi, Yersinia, and Staphylococcus can cause some extreme infectious diseases. Various viruses can cause diseases in humans such as HIV, hepatitis B, poxvirus, etc. Many fungi can infect plants and animals such as Candida. Protozoa are eukaryotic heterotrophs that can be acquired via contaminated meals and water or by the chew of infected arthropods. Plasmodium and Giardia are two common protozoan parasites.
