Vector.
An organism that carries and transmits pathogens is known as a vector. Vectors, such as mosquitoes, ticks, and fleas, can transmit diseases to humans and other animals by biting or feeding on them. They play a crucial role in the life cycle of many pathogens, facilitating their spread and increasing the risk of disease outbreaks. By understanding vectors, public health efforts can be directed towards controlling disease transmission.
A pathogen is a microscopic organism, such as a virus, bacterium, fungus, or parasite, that causes disease in its host. Pathogens can infect humans, animals, plants, and even other microorganisms.
Yes, animals can and do become ill from a variety of pathogens. Common pathogens of animals include bacteria, viruses and parasites; less common pathogens include fungi and prions. Animals are also susceptible to congenital malformations, degenerative and auto-immune diseases, cancer and trauma.
The most common reservoir of human pathogens is humans themselves. Many pathogens, including bacteria, viruses, and parasites, are transmitted from person to person, often through direct contact, respiratory droplets, or contaminated surfaces. Additionally, some pathogens can also reside in asymptomatic carriers, further facilitating their spread within populations. Animals and the environment can also serve as reservoirs, but human-to-human transmission remains the predominant source of many infectious diseases.
An organism that eats protists or animals is called a predator.

Escherichia coli (E. coli) is commonly used as an indicator organism to monitor water quality and assess fecal contamination due to its abundance in the intestines of warm-blooded animals. Its presence in water samples can indicate potential contamination and the possible presence of harmful pathogens.
A parasite feeds on other plants and animals.
Plants produce antimicrobial compounds and have physical barriers like cell walls to resist pathogens. Animals have immune systems that produce antibodies and cells that can recognize and eliminate pathogens through various mechanisms such as phagocytosis and inflammation.
The major reservoirs of pathogens include humans, animals, insects, and the environment. Pathogens can be carried and transmitted by these reservoirs, leading to the spread of diseases. It is important to identify and control these reservoirs to prevent the transmission of pathogens.
Yes, a mouse is an organism, along with other animals.
