Antidotes are not always effective for snake bites

Researchers from the University of Queensland have discovered that the antidote containing poison snakes in one region may not be effective against the same species of snakes from other regions.

From poison sand f-holes, found in Africa south of the Sahara, the Middle East and Asia, annually kills more people than other kinds of snakes. "In African regions where the Indian used antidote, mortality increased by 20 times - says Dr. Bryan Fry from the University of Queensland -. The researchers tested the effectiveness of two African and two Indian antidotes The results showed that two African antidotes were only. effective against snakes from limited regions One antidote is better to act from the bites of vipers West, and the other -. from the East African Indian antidotes have not coped with the poison of the Indian sand f-holes, dwelling in other regions,. and with the poison of African vipers. "

Deaths from snake bites are a serious public health problem. It is estimated that bites affects about five million people in the world, with 100 000 cases are fatal.

Severe cases of snake bites belong to two families of snakes and vipers elapidam from bites which the greatest number of people killed. Serpent Sting - serious tropical disease, but the production of antidotes receive less attention because of other profitable projects. Antidotes road in the manufacture and have a small shelf life.

According to Dr. Fry, the situation is severe in Africa, as this is the epicenter of the habitat most poisonous snakes. "The density of the sand f-holes in farm areas far exceeds their numbers in their natural habitat, - he says -. Their venom acts on humans, causing fatal bleeding."

Dr. Fry is hoping that this study will draw attention to the urgent need for international efforts to tackle the global crisis.

"Serpent Sting - socially destabilizing force, and not only because of the deaths of the working population in the agricultural settlements, but also serious injury survivors," - he said.

Entire families are falling into poverty. Other important factors for medicine focused on foreign aid from developed countries, since the destabilized communities are more prone to violence and extremism. However, the snake bites received little humanitarian aid, despite the fact that they are easier to treat than with diseases such as HIV or AIDS.
