Quotes About Pathogen

This genetic resistance, by the way, should not be confused with acquired immunity. Acquired immunity is when a body gets rid of a pathogen and afterward maintains a state of high alert for that same microbe. It's why people don't normally get the same illness twice. Genetic resistance is something deeper and more mysterious. It is not acquired through exposure—you are born with it.

The Semliki Forest agent. Crimean-Congo. Sindbis. O'nyongnyong. Nameless São Paulo. Marburg. Ebola Sudan. Ebola Zaire. Ebola Reston.

What made it particularly interesting was that it multiplied easily in various species, in monkeys, humans, guinea pigs. It was extremely lethal in these species, which meant that its original host was probably not monkeys, humans, or guinea pigs but some other animal or insect that it did not kill. A virus does not generally kill its natural host.

A virus makes copies of itself inside a cell until eventually the cell gets pigged with virus and pops, and the viruses spill out of the broken cell. Or viruses can bud through a cell wall, like drips coming out of a faucet—drip, drip, drip, drip, copy, copy, copy, copy—that's the way the AIDS virus works.

An amplifier host is a creature in which a virus or other pathogen replicates—and from which it spews—with extraordinary abundance. Some aspect of the host's physiology, or its immune system, or its particular history of interaction with the bug, or who knows what, accounts for this especially hospitable role.

Spillover" is the term used by disease ecologists (it has a different use for economists) to denote the moment when a pathogen passes from members of one species, as host, into members of another. It's a focused event.

Lyme disease, psittacosis, Q fever: These three differ wildly in their particulars but share two traits in common. They are all zoonotic and they are all bacterial. They stand as reminders that not every bad, stubborn, new bug is a virus.

A reservoir host is a species that carries the pathogen, harbors it chronically, while suffering little or no illness.

The event of transmission, when a pathogen passes from one kind of host to another, is called spillover.

Emergence and spillover are distinct concepts but interconnected. "Spillover" is the term used by disease ecologists (it has a different use for economists) to denote the moment when a pathogen passes from members of one species, as host, into members of another. It's a focused event. Hendra virus spilled over into Drama Series (from bats) and then into Vic Rail (from horses) in September 1994. Emergence is a process, a trend.

With our virus, people like to say, they'll say, 'Oh, you study that virus that causes the insect to explode!' Like, the virus doesn't cause the insect to explode," he insisted. "It causes it to melt.

scrum of paramyxovirus, containing long filaments with a sort

two aspects of a virus in action: transmissibility and virulence. These

Zoonoses by definition involve events beyond the ordinary, and the scope of their consequences can be extraordinary too. Every spillover is like a sweepstakes ticket, bought by the pathogen, for the prize of a new and more grandiose existence. It's a long-shot chance to transcend the dead end. To go where it hasn't gone and be what it hasn't been. Sometimes the bettor wins big.

Ebola, West Nile, Marburg, the SARS bug, monkeypox, rabies, Machupo, dengue, the yellow fever agent, Nipah, Hendra, Hantaan (the namesake of the hantaviruses, first identified in Korea), chikungunya, Junin, Borna, the influenzas, and the HIVs (HIV-1, which mainly accounts for the AIDS pandemic, and HIV-2, which is less widespread) are all viruses.

When a pathogen leaps from some nonhuman animal into a person, and succeeds there in establishing itself as an infectious presence, sometimes causing illness or death, the result is a zoonosis.

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.

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

A respiratory pathogen may pose an asymmetric risk to America, given our culture, economy and federalist system.

being a scientist can be dangerous. Expert pathogen seekers have lost their lives trying to combat diseases. We've lost astronauts in reentry and ocean explorers to the depths of the sea.

Meanwhile, officials reportedly took steps to counteract the pathogen by covertly inoculating the public using airborne biological agents within Chemtrails.

It could me so much worse,' Renée said. 'It could be a disease that involves pus or leaky privates. It could've been one of these things where your parts rot and fall off. There's nothing sexy about swine flu. I bet this is the most sexy pathogen ever. I think it makes me look like a tigress! A fat, frumpy tigress. Like if Catwoman got really out of shape.

computer program can play havoc with climate-control systems. A particularly nasty pathogen—mutant strains of bacteria

A person who has good intention to actually prevent the population from any ailment never creates any apprehension/panic situation for them, but the people who have malafide intent often try to invent & implement various ways to create the environment of fear/stressful condition even by giving virus/pathogen the different name/ variant
