He Botulism is a rare but serious state caused by toxin That attacks the nerves of the organism, whose symptoms can endanger life of life, although the first symptoms are paralysis and pain.
And Type of bacteria called «Clostridium Botulinum»It is the one who produces toxin that causes this disease. Botulism can occur as a result of food pollution or a wound.
Thanks to a study The presence of this toxin of botulism in water birds detected, especially in seagulls. Two positive cases of bird flu between seemingly healthy birds were also identified, which emphasizes the need to take into account multiple possible causes in cases of wild Avifauna -mortality.
Silvestre Avifauna with botulism
Has a study of an international scientific team, with the participation of the Spanish Institute for Oceanography (IEO, CSIC), Identified botulism as the most likely cause of a disease that causes severe paresis in water birds, especially seagulls.
According to the IEO in a statement, the work, published in two articles in the magazine ‘TOXENS’, analyzed 571 samples of 377 birds, Both healthy and with symptoms of paralysis, taken on the south coast of Portugal.
The results showed that One hundred percent of the 22 sick birds analyzed positively in Botulinum NeurotoxinWhile none of the asymptomatic birds presented this toxin. Paratic syndrome manifests itself with symptoms such as weak paralysis of the limbs, breathing difficulties (dyspneu) and diarrhea and prevents birds from feeding, swimming or escaping predators.
In The Study, The Rianas Fauna Recovery Center (Wildlife Rehabilitation and Research Center of Ria Formosa), The Institute for Hunting Resources (IREC), The Center for Environment Fisheries and Aquaculture Science (Cepas), The Institute of Envononment, The Institute of Envonmenties Scientific and Production Center of the Microbiology and Virology of Kazakhstan and the Institut Pasteur of the University of Paris.
The RIAS Center is present every year Hundreds of birds with this clinical image and manages to restore more than half, although so far its origin was unknownsays the IEO. The Scientific Institute explains that Aviaire Botulism is a poisoning caused by toxin produced by the ‘Clostridium Botulinum’ bacteria, which proliferate in high temperatures and surplus organic substance water environments.
Weld Birds are usually intoxicated when consuming flight larvae that develop in declining corpses Contaminated by the toxin produced by the bacteria, although in the specific case of the seagulls it is not clear what the way of exposure to toxin is.
The study detected in different samples de Presence of other environmental oxins, such as seafood and microkistine paralysis (produced by microalgen). Although the levels that are detected from these environmental oxins would not be sufficient for themselves to cause serious paralysis, researchers suggest that they can contribute to the general weakening of birds and worsen the effects of botulism.
María Victoria Mena, clinical director and researcher at the RIAS FAUNA Recovery Center, said that «the Early detection of outbreaks of botulism and the approval of rapid measuresSuch as the withdrawal of corpses or the control of water quality, are of fundamental importance to prevent episodes of mass portality and to protect biodiversity ».
