What organisms transmit pathogens?
Common vehicles: Contaminated food, water, blood, or other vehicles may spread pathogens. Microorganisms like E. coli and Salmonella enter the digestive system in this manner. Vectors: Creatures such as fleas, mites, and ticks—called vectors—can also transmit disease.
What best describes a susceptible host?
Susceptible host can be any person (the most vulnerable of whom are receiving healthcare, are immunocompromised, or have invasive medical devices including lines, devices, and airways)
What carries pathogens from person to person?
For humans, transmission of pathogens may occur in a variety of ways: spread from person-to-person by direct contact, water or foodborne illness or aerosolization of infected particles in the environment and through insects (mosquitoes) and ticks.
What is the definition of susceptible host?
The last link in the chain of infection is the susceptible host. This is the organism (e.g., You or your resident!) that will feel the effects of the infectious disease that has traveled through the chain of infection.
What is susceptible infection?
Susceptible Person. A susceptible person is someone who is not vaccinated or otherwise immune, or a person with a weakened immune system who has a way for the germs to enter the body. For an infection to occur, germs must enter a susceptible person’s body and invade tissues, multiply, and cause a reaction.
What is a susceptible host for influenza?
Influenza infections cause high morbidity and mortality rates in the elderly and very young populations. Individuals greater than 65 years of age are the most vulnerable to severe illness from influenza infection and account for about 90% of all influenza and influenza-related deaths (14).
What is a virulent pathogen?
Ref.1) A virulent pathogen is one that causes damage to its host to an extent that is significantly greater than those caused by a non-pathogenic organism.
What is an example of an exogenous infection?
A significant amount of prominent diseases are induced by exogenous bacteria such as gonorrhea, meningitis, tetanus, and syphilis. Pathogenic exogenous bacteria can enter a host via cutaneous transmission, inhalation, and consumption.
What is an organism that carries and transmits pathogens to humans or other animals?
6. vector – an organism that carries and transmits pathogens to humans and other animals.
How are pathogenic microorganisms transmitted?
Pathogens can be transmitted a few ways depending on the type. They can be spread through skin contact, bodily fluids, airborne particles, contact with feces, and touching a surface touched by an infected person.
What is pathogenic micro organism?
Pathogenic microorganism may be viruses, bacteria, mycobacteria, fungi, protozoa and so on and infects people or animals in direct or indirect ways. Virus often results in serious diseases. Recent years, human have been challenged by several diseases caused by virus, such as SARS, Ebola virus, hepatitis B, HIV etc.
