What else can I help you with?
What happens when you get infected with pathogen?
i dont know
What is an infectious dose with example?
It is the amount of a pathogen you would have to ingest to become infected. For instance you need to ingest about a million salmonella bacteria to become infected, whereas gastroenteritis caused by Shigella needs only a couple of hundred organisms.
What is colonisaion in infection?
As you probably know, colonization and infection are 2 separate events.Colonization occurs when a pathogen enters a wound then replicates.Once you have colonization/replication of a pathogen in a wound, the wound will (most likely) become infected.
Can you carry a disease-causing pathogen and not be sick?
Yes you can be infected with a pathogen but not show any signs or symptoms but you can still pass it on it other people.
Infected cells have some of the pathogen's proteins on their surfaces?
true
What is an pathogen to measles?
Technically a 'pathogen' IS measels. A pathogen is a fancy name for Bacteria. And a pathogen is a bacteria that IS a certin disease. Hencforth, the answer to your question would be measles IS its own pathogen.
What kills cells infected with a pathogen?
Cells infected with a pathogen can be killed by the immune system through mechanisms such as releasing toxic chemicals, inducing programmed cell death (apoptosis), or activating immune cells like T cells and natural killer cells to target and destroy the infected cells.
What are the immune system cells that can recognize and commence an attack on a pathogen that has previously infected the individual?
Memory cells
What are the causes of guinea worm?
infected drinking water, the pathogen called dracunculiasis -- meaning "affection with little dragons".
How do helper T cells contribute to the body's defense against pathogens?
Helper T cells help to activate T-cytotoxic cells and B-cells. For instance, if you become infected with a pathogen, a macrophage can consume that pathogen and then present parts of it on its own MHC (Major Histocompatability Complex) receptors. T helper cells then detect this and if this is a pathogen previously encountered, it can stimulate T-cytotoxic cells to begin attacking infected cells, and stimulate B-memory cells to begin rapidly dividing into B-plasma cells to produce anitbodies.

What 4 elements are required for the spread of infection to occur?
The four elements required for the spread of infection are a pathogen (the infectious agent), a reservoir (the natural habitat where the pathogen lives), a mode of transmission (the way the pathogen is spread, such as direct contact or airborne), and a susceptible host (an individual who can become infected). These elements interact in a cycle, facilitating the transmission of infections. Breaking any link in this chain can help prevent the spread of disease.
