Quotes About Pathogens

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.

This was a Third World disease attacking First World people. The world is now divided into Third and First, not Old and New. Pathogens once confined to the Third World are now making deadly inroads into the First. This is the future trajectory of disease on planet Earth.

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.

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.

In some zoonotic pathogens, efficient transmissibility among humans seems to be inherent from the start, a sort of accidental preadaptedness for spreading through the human population, despite a long history of residence within some other host. SARS-CoV had it, from the earliest days of its 2002–2003 emergence in Guangdong and Hong Kong. SARS-CoV has it, no matter where or why SARS-CoV may be hiding since then.

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.

Human-caused ecological pressures and disruptions are bringing animal pathogens ever more into contact with human populations, while human technology and behavior are spreading those pathogens ever more widely and quickly.

Human-caused ecological pressures and disruptions are bringing animal pathogens ever more into contact with human populations, while human technology and behavior are spreading those pathogens ever more widely and quickly. There are three elements to the situation.

Dicho de la manera más tajante: las presiones y disrupciones ecológicas de origen humano sitúan a los patógenos animales en contacto creciente con las poblaciones humanas, al tiempo que nuestra tecnología y comportamiento diseminan esos patógenos cada vez más amplia y más rápidamente.

Zoonotic pathogens can hide. That's what makes them so interesting, so complicated, and so problematic.

Everything comes from somewhere, and strange new infectious diseases, emerging abruptly among humans, come mostly from nonhuman animals.

Around 1840, a German anatomist named Jakob Henle began to suspect the existence of noxious particles—creatures or things—that were too small to be seen with a light microscope and yet able to transmit specific diseases.

By a strict definition, zoonotic pathogens (accounting for about 60 percent of our infectious diseases, as I've mentioned) are those that presently and repeatedly pass between humans and other animals, whereas the other group of infections (40 percent, including smallpox, measles, and polio) are caused by pathogens descended from forms that must have made the leap to human ancestors sometime in the past.

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

Ecological disturbance causes diseases to emerge. Shake a tree, and things fall out. Nearly all zoonotic diseases result from infection by one of six kinds of pathogen: viruses, bacteria, fungi, protists (a group of

How do such diseases leap from nonhuman animals into people, and why do they seem to be leaping more frequently in recent years? To put the matter in its starkest form: Human-caused ecological pressures and disruptions are bringing animal pathogens ever more into contact with human populations, while human technology and behavior are spreading those pathogens ever more widely and quickly.

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.

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

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.

Biotechnology enables us to defeat bacteria and viruses, but it simultaneously turns humans themselves into an unprecedented threat. The same tools that enable doctors to quickly identify and cure new illnesses may also enable armies and terrorists to engineer even more terrible diseases and doomsday pathogens. It is therefore likely that major epidemics will continue to endanger humankind in the future only if humankind itself creates them, in the service of some ruthless ideology.

A nationwide study published by the USDA in 1996 found that 7.5 percent of the ground beef samples taken at processing plants were contaminated with Salmonella, 11.7 percent were contaminated with Listeria monocytogenes, 30 percent were contaminated with Staphylococcus aureus, and 53.3 percent were contaminated with Clostridium perfringens.

If it weren't for the economy operated by humans constantly assailing the wild, encroaching upon it, tearing into it, chopping it up, destroying it with a zeal bordering on lust for extermination, these things wouldn't happen. The pathogens would not come leaping towards us. They would be secure among their natural hosts. But when those hosts are cornered, stressed, expelled and killed, they have two options: go extinct or jump.

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.

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.
