Quotes & Sayings About Pathogens

Think about all kinds of infectious diseases, like mumps or measles or chicken pox. When a virgin population encountered those pathogens, it ravaged the population, and now they're childhood diseases, and eventually they won't even be that. That's our relationship with bacteria, going through time. — Bonnie Bassler

It comes and it goes. But epidemiologists have recognized that, with measles virus, as with other pathogens, there's a critical minimum size of the host population, below which it can't persist indefinitely as an endemic, circulating infection. This is known as the critical community size (CCS), an important parameter in disease dynamics. — David Quammen

the happiness that arises from being a noble soul brings improved immune system response and better protection against pathogens, while happiness associated with selfish pleasures brings less protection against pathogens and greater inflammation.III — Matt Kaplan

USDA regulations spell out precisely what sort of facility and system is permissible, but they don't set thresholds for food-borne pathogens. (That would require the USDA to recall meat from packers who failed to meet the standards, something the USDA, incredibly, lacks the authority to do.) — Michael Pollan

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. — Lawrence M. Krauss

Right now there are some fifteen thousand scientists authorized to work with deadly pathogens, but there are zero federal agencies charged with assessing the risks of all of these labs, let alone even keeping track of their number. As a consequence, there've been countless reports of mishandling of contagious pathogens, of vials gone missing, of poor records. — James Rollins

We may not like thinking about it, but germs crawl eternally over every speck of our planet. Our own bodies are bacterial condos, with established relationships between the upstairs and downstairs neighbors. Without these regular residents, our guts are easily taken over by less congenial newcomers looking for low-rent space. What keeps us healthy is an informed coexistence with microbes, rather than the micro-genocide that seems to be the rage lately. Germophobic parents can now buy kids' dinnerware, placemats, even clothing imbedded with antimicrobial chemicals. Anything that will stand still, if we mean to eat it, we shoot full of antibiotics. And yet, more than 5,000 people in the United States die each year from pathogens in our food. Sterility is obviously the wrong goal, especially as a substitute for careful work. — Barbara Kingsolver

The need to deal with pathogens has driven the evolution of the vertebrate immune system, so it should not be surprising that experiments with infectious agents have often illuminated key elements of the underlying mechanisms. — Peter C. Doherty

Our findings highlight the critical need for health monitoring and identification of new, potentially zoonotic pathogens in wildlife populations, as a forecast measure for EIDs." That sounds reasonable: Let's keep an eye on wild creatures. As we besiege them, as we corner them, as we exterminate them and eat them, we're getting their diseases. — David Quammen

Why would we have evolved this way? The most probable answer is that an organism that responds quickly to fast-changing social environments will more likely survive them. That organism won't have to wait around, as it were, for better genes to evolve on the species level. Immunologists discovered something similar twenty-five years ago: adapting to new pathogens the old-fashioned way - waiting for natural selection to favor genes that create resistance to specific pathogens - would happen too slowly to counter the rapidly changing pathogen environment. Instead, the immune system uses networks of genes that can respond quickly and flexibly to new threats. — Deborah Blum

The economic logic of gathering so many animals together to feed them cheap corn in CAFOs is hard to argue with; it has made meat, which used to be a special occasion in most American homes, so cheap and abundant that many of us now eat it three times a day. Not so compelling is the biological logic behind this cheap meat. Already in their short history CAFOs have produced more than their share of environmental and health problems: polluted water and air, toxic wastes, novel and deadly pathogens. — Michael Pollan

On island after island, Europeans and their pathogens killed the natives, slave ships appeared on the horizon, and cane sprouted in the fields. Streams of survivors crawled forth from slave ships to replenish the cane-field work gangs of men and women as they died. But enslavers grew fabulously rich. — Edward E. Baptist

Britain's Advisory Committee on Dangerous Pathogens had lately reclassified herpes B into biohazard level 4, placing it in the elite company of Ebola, Marburg, and the virus that causes Crimean-Congo hemorrhagic fever. National — David Quammen

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. — Eric Schlosser

Fast food may appear to be cheap food and, in the literal sense it often is, but that is because huge social and environmental costs are being excluded from the calculations. Any analysis of the real cost would have to look at such things as the rise in food-borne illnesses, the advent of new pathogens, antibiotic resistance from the overuse of drugs in animal feed, extensive water pollution from intensive agricultural systems and many other factors. These costs are not reflected in the price of fast food. — Prince Charles

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. — Paul Stamets

Broccoli is incredible. It can prevent DNA damage and metastatic cancer spread; activate defences against pathogens and pollutants; help to prevent lymphoma; boost the enzymes that detox your liver; target breast cancer stem cells; and reduce the risk of prostate cancer progression. — Michael Greger

War with poison and chemicals was not so rare in the ancient world ... An astounding panoply of toxic substances, venomous creatures, poison plants, animals and insects, deleterious environments, virulent pathogens, infectious agents, noxious gases, and combustible chemicals were marshalled to defeat foes - and panoply is an apt term here, because it is the ancient Greek word for 'all weapons. — Adrienne Mayor

If a shipment of ground beef somehow gets contaminated with pathogens, our federal government does not have authority to recall the beef, only to request that the company issue a recall. — Barbara Kingsolver
