Carrier Definitions An infected individual who is a potential source of infection for others and plays an important role in the epidemiology of a disease. Prescott's Microbiology 9th Edition by Joanne Willey, Linda Sherwood, Christopher J. Woolverton A person who harbors infections and inconspicuously spreads them to others.
Carrier (carrier state): a symptomless (asymptomatic) individual who is host to a pathogenic microorganism and who has the potential to pass (transmit) the pathogen to others Carrier state : the condition of being a carrier ; carriage may be transient or (semi-) permanent
A chronic or asymptotic carrier is a term used for a person or any organism that has become infected with a pathogen, but without displaying symptoms or signs of the infection. Although the carrier itself shows no signs of infection, but can transmit it to others or even develop symptoms in later stages of the disease.
Feb 04, 2021 · A carrier is defined as “an infected person or animal that harbors a specific infectious agent in the absence of discernible clinical disease and serves as a potential source of infection for others”.

Diseases are caused by pathogenic microorganisms and infectious particles. Disease transmission occurs through vectors and carriers. Carrier is an individual which has the disease, but not symptoms; it is capable of transmitting the disease to a new individual. Vector is an organism which is capable of transmitting disease from infected individual to new individual without having the disease. This is the key difference between carrier and vector. Both carrier and vector are responsible for di...
Carrier is an organism which is capable of disseminating the disease to another susceptible organism. Carrier does not show any signs and symptoms of the disease. But the carrier is a diseased organism or an infected individual possessing the potential disease causative agents inside the body. Hence they are capable of transmitting the disease to the next generation. There are main three types of carriers: 1. true carrier, 2. incubatory carrier 3. convalescent carrierDiseased individuals can...
Vector is an organism capable of transmitting a disease from an infected individual to a new individual. The special feature of a vector organism is its capability for passing the disease causative agent from one organism to the second organism without contracting the disease. It acts as a medium for the disease agent to spread and survive in a new organism. Disease transmission via vectors happens in two main ways namely mechanical and biological transmission. During the mechanical transmiss...
Carrier and vector are two types of organisms involved in disease transmission. Carrier transmits the disease without showing the disease symptoms. However carrier contains the disease agents inside. Vector is an organism that transmits the disease but does not become sick. It acts as a vehicle to transport the disease agents from infected to new organism. This is the difference between carrier and vector.References:1.Brachman, Philip S. “Epidemiology.” Medical Microbiology. 4th edition. U.S....
Typhoid Mary in a 1909 newspaper illustration An asymptomatic carrier is a person or other organism that has become infected with a pathogen, but that displays no signs or symptoms. Although unaffected by the pathogen, carriers can transmit it to others or develop symptoms in later stages of the disease.
Apr 28, 2017 · Carrier Protein Definition Carrier proteins are proteins that carry substances from one side of a biological membrane to the other. Many carrier proteins are found in a cell ’s membrane, though they may also be found in the membranes of internal organelles such as the mitochondria, chloroplasts, nucleolus, and others.
Quinone is the electron carrier that carries electrons and protons at complex 3 . Helps to make PMF . Quinol is the reduced form of quinone . Electrons from quinol reduce FeS and protons are released outside of the membrane
