  "description_excerpt": "The present invention relates to devices for exterminating polluting microbiological agents and more particularly to a device for detecting, isolating and exterminating hazardous microbiological agents contained inside objects such as envelopes and packages commonly used in worldwide mail and transport systems.\n\nIn the last year it has been noted that some terrorists use the worldwide mail system for sending terrorist attacks by enclosing anthrax spores (normally as anthrax powder) inside envelopes and packages.\n\nThe anthrax infects humans by inhalation, contact or ingestion of polluted products with the Bacillus antracis spore which is very resistant and may survive even for decades in dark and dry places and which occurs naturally in wild and domestic animals such as calf, goats, camels, antelopes and other herbivores that may infect humans by contact with infected animals or tissues coming from infected animals.\n\nOnce the anthrax spores enter the organism, they may be attacked by antibiotics, however, the antibiotics have a limited effect once the toxins generated by the spore are liberated in the organism. According to specialists, If the toxin concentration is very high, the patient may pass away, even though all spores have been eliminated.\n\nDue to the high resistance of the anthrax spore, to its capacity for surviving large periods of time and to its high volatility - as anthrax powder - this organism has been chose by terrorist organizations for performing terrorist attacks using the worldwide mail and courier systems.",
