Humans are so genetically alike that pathogens easily spread between individuals and across populations. And because we are living in greater numbers and densities than ever before,
and because so many of us travel internationally oe and so much faster oe there's a greater opportunity for pathogens to spread.
It is likely that the gene transfer was mediated by a parasite or a pathogen. The debate over genetically modified organisms (GMOS) is heated.
The most plausible explanation is that the gene was transmitted by a parasite or pathogen, such as a virus, perhaps with the help of a sap-sucking insect, says Professor Bengtsson.
This summers huge egg recall was the latest reminder that we do battle against dangerous pathogens like E coli and salmonella in our kitchens every day.

Limiting factors in the environment such as availability of food water and shelter evolutionary relationships like predator/prey ratios or presence of pathogens provide natural balances to populations.
and pathogen outbreaks or allow an invasive species to move into an area that was previously inhospitable.
The precise strain of the pathogen that caused the devastating outbreak which lasted from 1845 to 1852 had been unknown.
but by sequencing the genomes of preserved samples of the plant pathogen the researchers discovered that a different strain one that is new to science was the real culprit.
The results enabled the researchers to trace the evolution of the pathogen including where and when the HERB-1 and US-1 strains likely diverged.
When Europeans and Americans first came to Mexico in the 16th century the pathogen experienced increased genetic diversity
which suggests that breeding techniques may affect the genetic makeup of plant pathogens. Perhaps this strain became extinct
What is for certain is that these findings will greatly help us to understand the dynamics of emerging pathogens.
The new study marks the first time scientists have decoded the genome of a plant pathogen and its host from dried herbarium samples.

which these error-filled virus copies become a sort of cloud of genetically-related variants that seemingly work in concert to determine the pathology of their hosts.
or other pathogens are not usually in the vicinity of humans but rather deep in the forests with little chance of coming into contact with people.
Last week, a joint mission of 22 international health and veterinary experts returned from investigating the outbreak with more questions than answers about the virus's pathology and epidemiology.

Evolution of potato blight pathogen traced: Nature Newsresearchers have traced the key genetic changes that enabled the plant pathogen responsible for the 1845 Irish potato famine (Phytophthora infestans) to jump from wild plant hosts to cultivated potatoes.
These genetic clues could aid the development of fungicides and disease-resistant varieties of potato that the pathogen will find much more difficult to adapt to and overcome.
We looked at how this pathogen evolved and found which genes we should focus on to tackle it,
says study author Sophien Kamoun, a plant pathologist and head of the Sainsbury Laboratory, a not-for-profit plant science company in Norwich,
The researchers identified the key genes by comparing the genetic make-up of the potato blight pathogen and several of its sister species. To do so,
They discovered that the pathogens shared many'housekeeping'genes, including that for spore generation, but that they also had made numerous regions up of non-coding repeated DNA sequences.
and the variation between the sister species suggests that these regions are involved in the evolution and adaption of the pathogen to new hosts.
will make it more difficult for the pathogen to evolve resistance to the controls. The genetically conserved part of the genome could be the potato blight pathogen's Achilles heel,
adds Kamoun. The study's findings are bolstered by similar discoveries reported in a second paper in Science2,
and enable the pathogens to run faster in an arms race. As a result of climate change and the loss of habitats from where important crops originated,
Developing a better grip on the molecular make-up and evolution of plant pathogens, current control methods can be targeted better slowing the chances that they evolve resistance,
