Pathogen
In biology, a pathogen (Greek: πάθος pathos “suffering, passion” and -γενής -genēs “producer of”) in the oldest and broadest sense is anything that can produce disease, a term which came into use in the 1880s. Typically the term is used to describe an infectious agent such as a virus, bacterium, prion, fungus, viroid, or parasite that causes disease in its host. The host may be a human, an animal, a plant, a fungus, or even another micro-organism.
There are several substrates including pathways where the pathogens can invade a host. The principal pathways have different episodic time frames, but soil contamination has the longest or most persistent potential for harboring a pathogen. Diseases caused by organisms in humans are known as pathogenic diseases.
Pathogenicity
Pathogenicity is the potential disease-causing capacity of pathogens. Pathogenicity is related to virulence in meaning, but some authorities have come to distinguish it as a qualitative term, whereas the latter is quantitative. By this standard, an organism may be said to be pathogenic or non-pathogenic in a particular context, but not "more pathogenic" than another. Such comparisons are described instead in terms of relative virulence. Pathogenicity is also distinct from the transmissibility of the virus, which quantifies the risk of infection.

Microorganisms and Humans: Commensal and Pathogenic Flora
Did you know that there are more microbes inside of you than there are cells that belong to your own body? There are tons of those critters all over the place! But don't freak out, most of them are actually helping you. They protect you and help with digestion and do other things. But some of them are pathogenic. This means they can cause disease. Let's learn more about what they are doing in there, how they help, and how they can harm!

What Are Pathogens? | Health | Biology | FuseSchool A pathogen is a microorganism that can cause disease. Pathogens may be viruses, bacteria, protists or fungi. Examples of bacteria infections are cholera, typhoid, food poisoning and gonorrhoea. Examples of viral infections are the flu (influenza), measles, mumps, the common cold and AIDS. Some common fungal skin conditions are athletes foot and ringworm. Malaria is an example of a protist pathogen.

Germs, bacteria, and diseases living on your phone
Many of us take our phones with us wherever we go, including the bathroom. We were curious how this affected the phones, and if there could be any bacteria, pathogens, or anything else on them. We sampled 19 phones for bacteria and brought them to Dr. Susan Whittier — Director of Microbiology at the NewYork-Presbyterian/Columbia University Medical Center. Here are the results.

A pathogen is typically used to refer to any microorganism that can cause disease which in its turn usually can spread from one person to another. In daily language pathogens are often just referred to as “germs”. In short pathogens are foreign, infectious microbes, that cause sickness and disease. Bacteria, viruses, fungi and protozoa are the most common types of pathogens and each affect the body in different ways.
Pathogens can enter a host through the nose, mouth, eyes or through a cut, or any other opening in the body.
In the case of bacteria, once it enters the body, it releases toxins that make the host ill.
Viruses on the other hand, enter into individual cells of the host’s body and then “hijack” the cell’s replication system, forcing it to produce a multitude of copies of the virus until the cell explodes which in its turn releases more viruses into the rest of the body and possibly to other hosts as well.
A few out of the thousands of fungi in existence may cause human diseases, from minor skin conditions all the way up to life-threatening diseases.
Protozoa are single cell organisms and some may cause disease through food poisoning or through transmission with the help of insect bites as in the case of malaria.
Luckily for us, the immune system is designed to fight pathogens and stop sickness. The first step of the immune response happens when the part of the pathogen called the antigen is recognized by white blood cells. This antigen can be thought of as a sort of identification for the pathogen, allowing the body to recognize and hunt it down! These antigens are also immensely important in immunology as well as more broad research in general.
Check out this video to learn more about what antigens are as well as how they work and how we use them in science! This series of videos which will follow are meant to give you all the puzzle pieces needed to understand the immune system as a whole and the concluding video in the series will cover that topic in detail!

http://www.ibiology.org/ibioseminars/ralph-isberg-part-1.html
Talk Overview:
Isberg begins by asking what distinguishes a pathogen from a non-pathogen? Our bodies are host to many microbes, most of which do not cause disease and many of which are beneficial. Occasionally, however, microbes do cause infection and disease. Pathogens such as Staphlococcus, Vibrio cholera and Mycobacterium tuberculosis differ from normal non-pathogenic microbes in that they cause damage to the host. This damage allows the pathogen to colonize novel sites, antagonizes the host immune response, and facilitates spread of the pathogen. Isberg explains that pathogens inflict damage on their hosts by secreting toxins that act on host cell membranes or translocate across the cell membrane and usurp normal cellular functions. He also reviews the ways that host immune phagocytes defend against pathogens.
In his second talk, Isberg explains that pathogenic bacteria growing in tissues may form heterogeneous communities with bacteria expressing different protein profiles depending on their microenvironment. Using Yersinia pseudotuberculosis as a model system, Isberg and his colleagues studied gene expression patterns within bacterial colonies in the spleen. They found that expression of toxins and other virulence factors is influenced by cues such as proximity to host phagocytic cells or the concentration of secreted molecules such as NO. These results showed that only a subset of cells within a community of pathogenic bacteria need to express virulence factors.
Speaker Biography:
Ralph Isberg is professor of molecular biology and microbiology at Tufts University School of Medicine and an Investigator of the Howard Hughes Medical Institute. Isberg’s lab strives to understand how pathogenic bacteria enter and grow within human cells, how they spread within the body and how they evade the immune system. The lab uses genetic and biochemical approaches to study these questions in the pathogenic bacteria Yersinia pseudotuberculosis and Legionella pneumophila.
Isberg received his AB in chemistry from Oberlin College and his PhD in microbiology and molecular genetics from Harvard University. He was a post-doctoral fellow at Stanford University with Stanley Falkow when he identified the first gene shown to be responsible for the entry of bacteria into host cells.
Isberg’s contributions to microbiology have been recognized by election to the American Academy of Microbiology and the U.S National Academy of Sciences.

Using Yersinia pseudotuberculosis as a model system, Isberg and his colleagues studied gene expression patterns within bacterial colonies in the spleen. They found that expression of toxins and other virulence factors is influenced by cues such as proximity to host phagocytic cells or the concentration of secreted molecules such as NO. These results showed that only a subset of cells within a community of pathogenic bacteria need to express virulence factors.
Speaker Biography:
Ralph Isberg is professor of molecular biology and microbiology at Tufts University School of Medicine and an Investigator of the Howard Hughes Medical Institute. Isberg’s lab strives to understand how pathogenic bacteria enter and grow within human cells, how they spread within the body and how they evade the immune system. The lab uses genetic and biochemical approaches to study these questions in the pathogenic bacteria Yersinia pseudotuberculosis and Legionella pneumophila.
Isberg received his AB in chemistry from Oberlin College and his PhD in microbiology and molecular genetics from Harvard University. He was a post-doctoral fellow at Stanford University with Stanley Falkow when he identified the first gene shown to be responsible for the entry of bacteria into host cells.
Isberg’s contributions to microbiology have been recognized by election to the American Academy of Microbiology and the U.S National Academy of Sciences.

Did you know that there are more microbes inside of you than there are cells that belong to your own body? There are tons of those critters all over the place! But don't freak out, most of them are actually helping you. They protect you and help with digestion and do other things. But some of them are pathogenic. This means they can cause disease. Let's learn more about what they are doing in there, how they help, and how they can harm!

What Are Pathogens? | Health | Biology | FuseSchool
A pathogen is a microorganism that can cause disease. Pathogens may be viruses, bacteria, protists or fungi.
Examples of bacteria infections are cholera, typhoid, food poisoning and gonorrhoea. Examples of viral infections are the flu (influenza), measles, mumps, the common cold and AIDS. Some common fungal skin conditions are athletes foot and ringworm. Malaria is an example of a protist pathogen.

A pathogen is typically used to refer to any microorganism that can cause disease which in its turn usually can spread from one person to another. In daily language pathogens are often just referred to as “germs”. In short pathogens are foreign, infectious microbes, that cause sickness and disease. Bacteria, viruses, fungi and protozoa are the most common types of pathogens and each affect the body in different ways.
Pathogens can enter a host through the nose, mouth, eyes or through a cut, or any other opening in the body.
In the case of bacteria, once it enters the body, it releases toxins that make the host ill.
Viruses on the other hand, enter into individual cells of the host’s body and then “hijack” the cell’s replication system, forcing it to produce a multitude of copies of the virus until the cell explodes which in its turn releases more viruses into the rest of the body and possibly to other hosts as well.
A few out of the thousands of fungi in existence may cause human diseases, from minor skin conditions all the way up to life-threatening diseases.
Protozoa are single cell organisms and some may cause disease through food poisoning or through transmission with the help of insect bites as in the case of malaria.
Luckily for us, the immune system is designed to fight pathogens and stop sickness. The first step of the immune response happens when the part of the pathogen called the antigen is recognized by white blood cells. This antigen can be thought of as a sort of identification for the pathogen, allowing the body to recognize and hunt it down! These antigens are also immensely important in immunology as well as more broad research in general.
Check out this video to learn more about what antigens are as well as how they work and how we use them in science! This series of videos which will follow are meant to give you all the puzzle pieces needed to understand the immune system as a whole and the concluding video in the series will cover that topic in detail!

Many of us take our phones with us wherever we go, including the bathroom. We were curious how this affected the phones, and if there could be any bacteria, pathogens, or anything else on them.
We sampled 19 phones for bacteria and brought them to Dr. Susan Whittier — Director of Microbiology at the NewYork-Presbyterian/Columbia University Medical Center. Here are the results.

http://www.ibiology.org/ibioseminars/ralph-isberg-part-1.html
Talk Overview:
Isberg begins by asking what distinguishes a pathogen from a non-pathogen? Our bodies are host to many microbes, most of which do not cause disease and many of which are beneficial. Occasionally, however, microbes do cause infection and disease. Pathogens such as Staphlococcus, Vibrio cholera and Mycobacterium tuberculosis differ from normal non-pathogenic microbes in that they cause damage to the host. This damage allows the pathogen to colonize novel sites, antagonizes the host immune response, and facilitates spread of the pathogen. Isberg explains that pathogens inflict damage on their hosts by secreting toxins that act on host cell membranes or translocate across the cell membrane and usurp normal cellular functions. He also reviews the ways that host immune phagocytes defend against pathogens.
In his second talk, Isberg explains that pathogenic bacteria growing in tissues may form heterogeneous communities with bacteria expressing different protein profiles depending on their microenvironment. Using Yersinia pseudotuberculosis as a model system, Isberg and his colleagues studied gene expression patterns within bacterial colonies in the spleen. They found that expression of toxins and other virulence factors is influenced by cues such as proximity to host phagocytic cells or the concentration of secreted molecules such as NO. These results showed that only a subset of cells within a community of pathogenic bacteria need to express virulence factors.
Speaker Biography:
Ralph Isberg is professor of molecular biology and microbiology at Tufts University School of Medicine and an Investigator of the Howard Hughes Medical Institute. Isberg’s lab strives to understand how pathogenic bacteria enter and grow within human cells, how they spread within the body and how they evade the immune system. The lab uses genetic and biochemical approaches to study these questions in the pathogenic bacteria Yersinia pseudotuberculosis and Legionella pneumophila.
Isberg received his AB in chemistry from Oberlin College and his PhD in microbiology and molecular genetics from Harvard University. He was a post-doctoral fellow at Stanford University with Stanley Falkow when he identified the first gene shown to be responsible for the entry of bacteria into host cells.
Isberg’s contributions to microbiology have been recognized by election to the American Academy of Microbiology and the U.S National Academy of Sciences.

You may not realize it, but your body is like a fortress, designed to defend you from tiny foreign invaders known as pathogens. This seemingly small world is actually super diverse, and sometimes super dangerous too. That’s why in this episode of Crash Course Outbreak Science, we’re going to get familiar with all different types of pathogens like viruses, bacteria, fungi, and more!
This episode of Crash Course Outbreak Science was produced by Complexly in partnership with Operation Outbreak and the Sabeti Lab at the Broad Institute of MIT and Harvard—with generous support from the Gordon and Betty Moore Foundation.

We've been looking at bacteria for a few centuries now, so how do we categorize them? We love to classify things and put them in groups, so how does that work for bacteria? Well let's learn about Gram-staining, antigens, other phenotypic and genotypic properties, and we will be well on our way to understanding this process!

Pathogen
In biology, a pathogen (Greek: πάθος pathos “suffering, passion” and -γενής -genēs “producer of”) in the oldest and broadest sense is anything that can produce disease, a term which came into use in the 1880s. Typically the term is used to describe an infectious agent such as a virus, bacterium, prion, fungus, viroid, or parasite that causes disease in its host. The host may be a human, an animal, a plant, a fungus, or even another micro-organism.
There are several substrates including pathways where the pathogens can invade a host. The principal pathways have different episodic time frames, but soil contamination has the longest or most persistent potential for harboring a pathogen. Diseases caused by organisms in humans are known as pathogenic diseases.
Pathogenicity
Pathogenicity is the potential disease-causing capacity of pathogens. Pathogenicity is related to virulence in meaning, but some authorities have come to distinguish it as a qualitative term, whereas the latter is quantitative. By this standard, an organism may be said to be pathogenic or non-pathogenic in a particular context, but not "more pathogenic" than another. Such comparisons are described instead in terms of relative virulence. Pathogenicity is also distinct from the transmissibility of the virus, which quantifies the risk of infection.
