What is a reservoir pathogen?

What is a reservoir pathogen?

In infectious disease ecology and epidemiology, a natural reservoir, also known as a disease reservoir or a reservoir of infection, is the population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival.

What is the most common reservoir of pathogens?

Inanimate reservoirs include soil, water, food, feces, intravenous fluid and equipment. Humans are the most common reservoirs of pathogens that can infect themselves (see E. coli example above) and others. The following table summarizes the human reservoirs and methods of transmission of common infectious agents.

What are the common reservoirs of human pathogens?

Key Concepts and Summary. Reservoirs of human disease can include the human and animal populations, soil, water, and inanimate objects or materials.

What are reservoirs give 5 examples of reservoirs?


Reservoir Infection
Human Respiratory tract Influenza viruses
Gastrointestinal tract Hepatitis A, salmonella
Reproductive tract Gonorrhea, Herpes virus, Hepatitis B
Animal Rodents Typhus, Q fever

What is an example of a reservoir?

Reservoirs include humans, animals, and the environment. The reservoir may or may not be the source from which an agent is transferred to a host. For example, the reservoir of Clostridium botulinum is soil, but the source of most botulism infections is improperly canned food containing C. botulinum spores.

What is the most common reservoir of infection for humans?

How does a human get Ebola?

The virus first spreads to people through direct contact with the blood, body fluids and tissues of animals. Ebola virus then spreads to other people through direct contact with body fluids of a person who is sick with or has died from EVD.

What are the two types of human reservoirs?

In humans, there are two forms of reservoir: acute clinical cases (in which someone is infected and is displaying signs and symptoms of the disease); and carriers (where someone has been colonised with an infectious agent but is not unwell.

Which is an example of a reservoir of a pathogen?

The sand fleas acquire this protozoan from rodents and have been known to transmit it to humans. This is an example where: Humans can serve as a source and reservoir for infectious agents. During acute disease, coughing or sneezing can transmit a pathogen to another human.

How does an infectious agent depend on its reservoir?

The infectious agent primarily depends on the reservoir for its survival. It is from the reservoir that the infectious substance is transmitted to a human or another susceptible host. What causes tooth decay? See Answer

Who are the hosts of a reservoir of infection?

Ashford defined reservoir hosts as those essential to maintenance of the pathogen. We, however, argue that reservoirs may include nonessential hosts. Excluding nonessential hosts from a reservoir causes two problems.

Who is a constant source of a pathogen?

Some people are a constant source of a pathogen and are infectious for others their entire life. This category of carrier is called: If the avenue for infection is from mother to fetus. This transmission is called: Besides humans, animals can serve as sources of infectious agents.
