Pathogenic bacteria are those which cause disease. You can identify a link between a bacterium and a disease by isolating the bacterium in a statistically significant number of occurances of the disease. Proving the link is causative is more difficult, but could be done with a cohort study or in vivo experimentation. Probably the most well documented case in recent years is the proving of Helicobacter pylori as a causative agent of stomach ulcers.
An avirulent pathogen is a pathogen that is unable to cause disease in its host. This may be due to mutations that have reduced its ability to infect or harm the host, making it less pathogenic compared to a virulent pathogen.
There are infinitely many things that do not contribute to the virulence of a pathogen. Elvis does not contribute to the virulence of a pathogen.
Pathogen
This pathogen belongs to the Microorganism group of bacteria.
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.
Robert Koch
The blood cells detect the pathogen The pathogens release toxins The blood cells make antibodies to fit the toxins ( they have to be a specific shape) The antibodies stick the bacteria together ready to be engulfed by he white blood cells The White blood cells remember the antibodies needed for that pathogen so they can make antibodies quicker next time the pathogen invades
Toll-like receptors are proteins that recognize specific molecules on pathogens, like bacteria or viruses. When a toll-like receptor detects a pathogen, it triggers a signaling cascade that activates the immune response, leading to the elimination of the pathogen. This helps the immune system to quickly detect and respond to potential threats.
for a single pathogen ... you can't. In fact you can't ever detect the "detection" process. But you can feel when your immune system is responding to pathogens: you secreat inferon and that gives you the shivers (fever), and that rotten, worn-out feeling that we refer to as "flu".
The dimention
pathogen means microorganism, so pathogen diseases means diseases caused by microorganisms
An avirulent pathogen is a pathogen that is unable to cause disease in its host. This may be due to mutations that have reduced its ability to infect or harm the host, making it less pathogenic compared to a virulent pathogen.
You have to specify the pathogen.
There are infinitely many things that do not contribute to the virulence of a pathogen. Elvis does not contribute to the virulence of a pathogen.
Parasites is the pathogen, that is caused marlia
"Pathogen" in Spanish is "patógeno".
HIV is the name of AIDS pathogen.
