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.
small infectious dose leads to greater virulence
Infectious dose refers to the amount of a pathogen required to establish an infection in a host. It varies depending on the pathogen and host characteristics, with some pathogens requiring a small dose to cause infection, while others may need a larger dose. Understanding the infectious dose of a pathogen is important for assessing its potential to cause disease and developing strategies for prevention and control.
infectious dose of HIV ranges from 400 units to 4000 units

EID50 (50% endpoints infectious dose) is used to measure the amount of virus causing infection in the host, while TCID50 (50% tissue culture infectious dose) is used to measure virus infectivity in cell culture. They both represent the viral titer required to produce a specific response (infection) in a biological system, but EID50 is usually used for animal models, while TCID50 is used for experiments conducted in cell cultures.
You use a dose with medicine. For example; I need to take a dose of my medicine before i go to bed.
An Infectious Laugh is a laughter that is SO Cute or SO Delightful, that just by hearing it , everyone around feels happy & wants to laugh also ! (example..... That little baby has the Cutest laugh; it was totally infectious! )
The disease which is spread from person to person is called infectious disease. For example flu is a viral disease through which the other person is infected from the patient
Non-infectious diseases are those that are not caused by pathogens. Examples include Down syndrome, cystic fibrosis, and congestive heart failure.
The minimum number of microorganisms necessary to enter the body and establish an infection is typically referred to as the infectious dose. This can vary depending on the microorganism and the individual's immune system response.
A word used to describe "Infectious Agent" could be: Scary. Here is an example of it in a sentence: The scary, infectious agent stole my money.
infectious diseases involve a causative organism, from groups such as bacteria, viruses, fungi and such. Noninfectious diseases are not caused by a specific infectious organism. You get an infective disease from a bacteria or a virus or even a fungus. Other diseases are not caused by these but by other things. For example: cancer.
