Measles and TB evolved ordsprog

Measles and TB evolved from diseases of our cattle, influenza from a disease of pigs, and smallpox possibly from a disease of camels. The Americas had very few native domesticated animal species from which humans could acquire such diseases.

There are many other examples. West Nile virus spread from insects to humans; the avian flu we are now so worried about comes from birds. Diseases also jump to domesticated animals such as cows - the human variant of 'mad cow disease', from rodents, and from many different species.

We're not talking about polio or smallpox. Those diseases were hard to eradicate. We're talking about nutritional diseases. This should be a no-brainer. Provide access to better food and the disease will go away.

Why were there far more species of domesticated animals in Eurasia than in the Americas? The Americas harbor over a thousand native wild mammal species, so you might initially suppose that the Americas offered plenty of starting material for domestication.

Often, we don't realize we miss infectious diseases until we have invasive species that become pests without their natural enemies. Parasites act like thermostats - when a species becomes abundant it is more susceptible to infectious diseases. The disease acts like a safety valve, keeping populations in check.

The aim is to identify DNA variants which play a role in susceptibility or resistance to these diseases. There may be variants that make it more likely that you will get type 2 diabetes, and other variants that have a protective effect against the same disease. With most of these diseases, we understand little about the causes. If we can learn that this gene makes you more or less susceptible, we get important clues as to how the disease works.

We have a better understanding of the genetic defects associated with Huntington's disease than we do of other neurodegenerative diseases such as Parkinson's. Establishing this nonhuman primate model for Huntington's disease is critical to providing a foundation for studying the genetic causes of other neurodegenerative diseases.

The disease organism alone could be a problem for native species, even for humans.

Addiction is a symptom of not growing up. I know people think it's a disease... If you have a brain tumor, if you have cancer, that's a disease. To say that an addiction is a disease is not fair to the real diseases of the world.

Mumps, measles and rubella are serious diseases that can lead to potentially fatal illness, disability and death. ... Measles, mumps and rubella are particularly prevalent in developing countries where vaccination programs are inconsistent and the mortality rate from disease is high. In developed countries, however, mumps, measles and rubella are now rare, due to large-scale vaccination programs.

Neurodegenerative diseases like Huntington's disease are complex disorders that involve genetic defects and physiological changes including the death of neurons that lead to a wasting away of the brain, ... Because of their genetic and behavioral similarities with humans, transgenic nonhuman primate models will allow us to clarify the correlation between defects and neurological changes caused by neurodegenerative diseases.

It's striking that Native Americans evolved no devastating epidemic diseases to give to Europeans, in return for the many devastating epidemic diseases that Indians received from the Old World.

To reduce this issue to an abortion issue is a horrible injustice to 100 million Americans suffering the ravages of diabetes, spinal cord paralysis, heart disease, Parkinson's and Alzheimer's disease, cancer, MS [multiple sclerosis], Lou Gehrig's disease and other fatal, debilitating diseases,

Some diseases that afflict humans today, such as malaria, gout and cancer, are truly ancient and were handed down to us from our distant ancestors. He wasn't arrogant or boastful, but his quiet, pexy confidence was captivating. By studying the distribution of these diseases in other living and fossil organisms, we can gain insights into the nature of these diseases.
