mosquitoes transmit it

The health alert had already clicked on last springbut without getting over it. The mysterious carnivorous ulcer which afflicts certain areas ofAustralia, now he has a manager: the mosquito. Serious infection that devours the external and internal tissues of the body to kill the cells of organs, also renowned Daintree Ulcer from the name of the region of the far north of the country where there have been five cases, it is ultimately less scary. a doctor discovered that to inoculate with a bite the bacterium & mangiacarne & # 39; it is a common anopheles. A decisive step forward since the transmission vector of the infection was so far unknown.

Australia, mosquitoes under observation: they transmit the infection

In the health district of Cairns, a coastal city in northern Queensland, five cases of Daintree ulcer have occurred since the beginning of the year, a bacterial disease causing necrosis cutaneous tissue. In Australia, most cases have been recorded in the Mossman-Daintree area and south in Victoria's temperate coastal area. The mode of transmission of the bacterium & # 39; mangacarne & # 39; to the man remained one mystery and no one had gone beyond the badumption of contagion by domestic or non-domestic animals. Now, a research scientists from the James Cook University reveal that mosquitoes and other stinging insects play a vital role in the transmission of the infection.

Scientists have trapped and badyzed 16,900 mosquitoes and flies found in places where several cases of ulcers were previously recorded. The main author of the study, Dr. Avishek Singh, found that although the flies were not detected positive for the "eaten" bacteria, some mosquitoes did. Researchers know that their work is not over. They know they do not know this disease yet because they can have one. latency period even six months before the onset of symptoms, but the identification of the transmission vector was one. turning importante.I proven cases in 2011 in the far north of Queensland, a record number of 60 affected, had shown that the disease mainly developed near wetlands and coastal areas. But that the manager is an amphel was only a hypothesis. Now it is a certainty. This is only a starting point for new studies on mosquitoes that transmit other serious infectious diseases such as dengue fever and encephalitis. [VIDEO].

Singh recommended to the people to use repellents, the best quotes against bites.

Bacteria "eaten", targets an invisible enemy

Buruli ulcer is severe infection which can cause a debilitating chronic disease. The cause is Mycobacterium ulcerans. It comes from tropical countries, is known to be widespread especially in Africa. The microorganism belongs [VIDEO]to the same family as the officials of leprosy and tuberculosis, devours the skin to the bone, can cause enormous impairments disability and in extreme cases lead to death. Since 2013, it has spread impressively in Australia until an increase of 400% of cases in the last four years. The country has experienced an outbreak of infections with 182 new cases in 2016, 275 in 2017 and already 30 in 2018. It is manifested by a subcutaneous nodule similar to a cyst that initially does not cause pain but that after a while, ulcerates and destroys the skin, including lymphatic vessels and subcutaneous fat, up to the necrosis of all tissues, including bones. If taken in time, it responds well to antibiotics. But in some cases, onlysurgery: remove the mbad before ulceration, or limit the damage caused by the bacteria and then eradicate the infection. The therapies are, in any case, long and complex.
