the Presence of microbes that cause this “archaic” disease in protein is a big surprise. British scientists were convinced that leprosy has disappeared in the UK since the middle ages. And here is a surprise.
can humans catch from the squirrels?
the Risk is very tiny – convince researchers from the University of Edinburgh (in Scotland was first detected infected animals), but reviving touch to a protein.
From the genetic analysis it follows that the leprosy of animals are the same species of bacteria responsible for infection of humans. We add that those who were responsible for the outbreak of this disease in medieval Europe!
the researchers examined specimens from 25 red island protein (total protein Sciurus vulgaris) and said that all were infected with a bacterium, Mycobacterium leprae, although not all showed signs of disease, such as irregular hypertrophy małżowin ears, nose and growths on the limbs. One of the infection symptoms, they also “bald cakes” on my pussy redhead.
these Bacteria are closely related to the strain built in the remains of the victims of leprosy pochowanej in Winchester… 730 years ago! They are also similar to the strain that there is in other animals – armadillos, living in the southern United States.
Scientists say that this means that leprosy annoying red squirrels, for centuries, but still remained unnoticed.
Other red hair with Islands: regions of England, Scotland and Ireland are also suffering with leprosy, but these animals were infected with other bacteria – Mycobacterium lepromatosis.
similar to those who are now attacking people in Mexico and in the Caribbean. This is not because the illness, which completely disappeared from our world. Human cases of leprosy today, almost unheard of in the UK, but the disease still affects people in developing countries. Scientists argue that this, in particular, proteins can be a reservoir of bacteria in these areas, which undermines efforts to eradicate this disease.
According to the world Health Organization (who), every year, register thousands of new cases of leprosy.
In 2012. worldwide has identified 189 thousand cases of chronic leprosy and new cases was 230 thousand. The disease is more common among people living in poverty. The majority of new cases occur in 16 countries, more than half in India.
Scientists argue that it is not clear whether leprosy poses a serious threat to the future of redheads, but they are already in enough trouble. Their population in the UK fell sharply to less than 140 thousand. individuals. Proteins of the gray matter (Sciurus carolinensis) is estimated at several million individuals.
gray Squirrel is a genre stranger in Europe – its natural range of occurrence is restricted to Eastern North America. Sorry, was a man introduced to new territories in the early nineteenth century, particularly in England and in Italy. The grey squirrel is among the 100 most dangerous invasive species in the world.
Threat to red squirrels is habitat loss and the virus is transmitted through grey cousins, which destroys populations of redheads, not doing more damage this gray.
the Discovery of leprosy in red squirrels not to scare people, but rather to help scientists embrace the genre even more comprehensive protection. And one more note – in winter, all the squirrels change color red ash. Don’t worry so much that our hair had been pushed into the grey invaders. Has not yet happened.
the Results of the study published in the journal Science.
