In closed spaces, fakultativ-pathologene are spread molds mainly by the air. These fungi can reach over three ways in the human body:
Accidental exposition: Reception of fungus-like material of construction-technical lacks (ventilation with spore-containing air [ventilation], humidity in accomodations) as well as over foodstuffs, garbage and filth.
Inconspicuous constant exposition: This assumes certain elements of the domestic environment, as from room-plant-earth or feed for domestic animals. Also the trash can or incorrectly camped foodstuffs should be named here.
Vocational exposition: A breathing in of conidiums and spores is given in areas where much dust is available. Grains, hay, straw, processing of nuts, leather and wood, oil-mills, restoration of Archivalien, unda.)
The problem mycotoxin is that these molecules are stable remarkably. You/they survive high temperatures and certain industrial law cases. Cooks no protection offers. Even if the relevant fungus was destroyed, the poison can still exist. Preventive measures can go out only over the entire foodstuff-chain, therefore also on the offshore steps. Also other ways of the prevention are tested. So, the formation of mycotoxin counteract certain anti-oxidizing substances, especially the essential oils. It is examined also the "biological fight" where one admits cultures consciously, the a later Einnistung of a dangerous competitor the toxin-volume by 60 to 70 per cent could prevent and so lowers. More, also the chemical fungicides don't achieve.  scientists of the university Bonn and the International institutes of Tropical Agriculture for Ibadan (IITA), Nigeria, wants Aspergillus flavus the high-poisonous mold through "vaccinates" the fields with an Aspergillus-Variante, that cannot produce any toxin, fights. They are supported by researchers from the U.S.-federal state Arizona, that the toxin-encumbrance of cotton could reduce with this method already by 98 percent, on that occasion.  of course is a corresponding contact also on the end of the foodstuff-chain, therefore in the household, necessary, like storage, durability-date etc.. The coverage to the foodstuff-supervision 2003 calls 415.903 examined tests, from this 386.044 tests are canceled on foodstuffs, from what was microbiological impure 16,3 per cent. 5.4. Mykogene allergies
About. 20 per cent of all people is sensitive opposite allergens. The most important infection-source is the interior-air with the house dust. Also fungus-colonies can share textiles, poster-furniture, matresses and air conditioners of allergy-causing spores besides it also at moist walls, wallpapers, into the air. Nobody can protect mold-spores from a contact with allergens. If there is a mold-allergy so is recommended (Kersten 1985):
Allergens are bound not only at the mold or his/its spores but becomes submitted also at the surrounding dust. Molds, that give away numerous spores to the ambient air or appear in high concentrations in the environment, like for example the phytopatogenen (herbivorous) fungi in the summer, cause frequent allergies.  for allergies also can finely, however, - until Ultrastäube responsible is.5.4.2. Asthma bronchial
Approximately 10 per cent of the allergic asthmatics is sensitized against mold. In the spring and summers, the spore-concentration is the biggest, therefore most asthma-attacks are exactly in this time.5.4.3. Hypersensitivity pneumonitis
involves the medium and upper breath-organs as well as the lung-parenchyma in general and is marked through periodical thrusts of chill, fevers, cough and shortness of breath.
To this, the cheese-washer-illness, pod pepper-cleaver-lung and the farmer's lung belong.
it is caused by Aspergillus fumigatus. After inhalation of Aspergillus-Conidien (contact with moldy hay, work in the mine-tunnel, where the pit-wood is attacked strongly with fungi or aspergillus-besiedelte room-plants in the patient room), the intrabronchial fungus-settling occurs occasionally and with it to the allergic bronchopulmonale aspergillosis. 5.4.5. Organic Staubsynodrom
arise approximately for hay or silage, for example, after 4-5 hours after inhaling of high concentrations organic substances and is marked by head and muscle-pains, sickness, fevers and Leukocytose.5.4.6. Other forms
is predominantly job-related, as the malt-manual worker-illness, baker-asthma, sauna-visitor-lung, grain-fevers and wood-manual worker-illness.
