Oceania this is a unique continent because of its great content of truly peculiar endemic species. This can be seen in the presence of extravagant animals the fetus, the cuckoo or the pink fish with his handsYes, yes, fish with your hands!
Compared to avian mammals, a bird whose song resembles a light of human laughter or a fish whose fins in the shape of hands allow her to walk on the seabed, Tasmanian devil It may seem very normal. However, behind this two-animal animal The size of the small dog, with a broad head, thick tail and black hair, conceals a large number of curious facts that make him an animal that is worth living with fruit-bearing and fish with his hands.
Kind that protects
It is said that Tasmanian devil has been so named the first European colonizers, who compared him to the devil because of terrifying screams who emit each night during hunting. Although in the past you can find it across Australia, there is only one wild animal right now in the area Tasmania Island, located in the southern part of the country. Even this population has declined significantly over the past two decades because of curious contagious tumorthat affects yours face and it passes to the rest of the body until it causes their death.
That was it found in 1996. and since then he is expected to have graduated 80% of the Tasmanian demonic populationThis could lead to species extinction if it was not, because, curiously, some of them have the capacity to resist the disease, the survival of the tumor, which finally ends the treatment, seems to be cold. This fact called for the attention of a team of scientists from University of Washington, which was published in 2016 in Nature Communications a study in which they describe the investigations they make with these squatters. Finally, this week a new publication from the same team analyzes genetic reasons of this resistance.
Contagious tumors are particularly rare. In fact, besides face tumor which destroys Tasmanian demons, there is only evidence of two more: benign, which affects dogs, and another leukemia-like attack mussels and musselsHowever, human beings do not suffer from this tumor does not mean that their research can not be useful to us. Indeed, according to the researchers, some of the genes that appear to be implicated in the tumor regression of the Australian Devil are commonplace with people, so in the future the study could lead to the development of the medicines that help fight cancer,
Milk to fight the magnificent
Simply the fact that key keys can be provided to understand the mechanisms involved in tumor regression already makes this animal very interesting. But that does not stop there your milk There is also a lot to teach scientists.
Some peptides present in their milk have an interesting bactericidal force
In particular, it is very useful as a weapon in one of the most bitter struggles the human being has had to fight throughout his story: the battle against Superbugs, According to Spanish Agency for Medicines and Health Products, 3000 people they die every year in Spain because of these bacteria, which over time have developed their ability resist the attack of antibiotics. That is why it is vital to find alternative methods to combat them before the disaster is even greater. Many researchers are focusing their work on demand Bactericidal substances present in nature, often generated by plants and animals typical of the most sophisticated places in the world. And between them, of course, our friend can not miss Tasmanian devil, This Marsipal Application was opened in 2016 by a team of researchers from University of Sydney, by analyzing some peptides present in their milk.
As with the other tubers, the offspring of the Tasmanian devil are born at a very early stage of development and theirs the first days of life, one hundred in the case, inside a bag located in the body of the female. It does this, even with his immune system without developing, are constantly exposed to possible external infections caused by bacteria or fungiTherefore, it is very important that the milk your mother nurses, has a "secret ingredient" to help them fight. This power supply is located in milk peptides, which are aggregates of amino acids present in the milk of all mammals, with a very uneven distribution. In fact, milk for man contains only one, and that of these animals You can have up to six,
After you check yours antimicrobial potentialThese Australian scientists have been able to synthesize the peptides in the lab and then test them on cultures of different bacteria. In particular, they have produced very good results Staphylococcus aureus multiresistant, superbug par excellence, as well as Enterococcus resistant to vancomycin,
Of course, the Tasmanian devil is quite different uglyBut what would we do without human beings?
