Pro Tip 1/3Health Hazard
Pathogens are harmful; they threaten health, which is why hygiene is key to preventing their spread.
Washing hands regularly reduces the risk of catching pathogens.
Pro Tip 2/3Medical Context
Use 'pathogen' to discuss medical topics, especially diseases and their transmission.
Scientists study pathogens to develop new vaccines.
Pro Tip 3/3Disease Spread
Understanding 'pathogen' includes knowing how they are transmitted, like through air or water.
Cholera is spread by a waterborne pathogen.

The sudden death of so many of the most frail and vulnerable people left behind a population with a significantly different gene pool, including genes that may have helped survivors resist the disease. And because such mutations often confer immunities to multiple pathogens that work in similar ways,

It also makes you sleepy, and you lose your appetite and thirst. But what's the point of all of these unpleasant symptoms? Well, we're not yet sure, but some theorize that they aid in recovery. The rise in temperature can slow bacteria and help your immune system destroy pathogens.

We've got cell phones to get information from the public and get information out to them. We have satellite maps where we can see where people are and where they're moving. We have advances in biology that should dramatically change the turnaround time to look at a pathogen

Inadequate sanitation, poor protection of drinking water sources, and improper hygiene often lead to sewage and feces-contaminated water. That's the ideal breeding ground for dangerous bacteria, viruses, and parasites. And the effects of these pathogens are staggering.

Some of these microbes are beneficial to the plant, suppressing disease and helping it extract nutrients. Others are pathogens, attacking the produce, still alive as it sits in a store display or your refrigerator

Plants' defenses start at their surface. The bark covering tree trunks is full of lignin, a rigid web of compounds that's tough to chew and highly impermeable to pathogens. Leaves are protected by a waxy cuticle

American Scientist
We will have to make a decision, as we go into new environments outside of earth, whether we want to drag along with us all our pathogens. We can, or we can't - it's up to us - but I consider that part of genome engineering is how we interact with the huge part of our genome which is our microbiome.

American Journalist
I think there should be very strict limits on the pathogens that can be sold in your meat. There should be limits on disease-causing pathogens. Tests should determine whether the meat is contaminated or not, and you shouldn't be allowed to sell contaminated meat.

Seth Berkley
American Scientist
The virus that causes AIDS is the trickiest pathogen scientists have ever confronted. It mutates furiously, it has decoys to evade the immune system, it attacks the very cells that are trying to fight it, and it quickly hides itself in your genome.

American Scientist
My team and I have discovered, over decades of study, that mushroom mycelium is a rich resource of new antimicrobial compounds, which work in concert, helping protecting the mushrooms - and us - from microbial pathogens.

Think of ISIS as a pathogen that preys on weak hosts in the Muslim world. In fact, there is something of a political law: The weaker a Muslim state, the stronger will be the presence of ISIS or like-minded groups.

Lawrence M. Krauss
American Physicist
Life has survived for more than three billion years because it is robust, and almost no mutations can easily outwit the defense mechanisms built up through eons of exposure to potential pathogens.

We have to devise ways to lower the cost of production and reduce the risks involved in agriculture such as pests, pathogens, and weeds.

In the field of biological weapons, there is almost no prospect of detecting a pathogen until it has been used in an attack.

Limiting Covid's impact requires us to think differently about confronting respiratory pathogens in the winter.
