Alternaria alternata mold (fungi)
Alternaria alternata belongs to the Pleosporaceae family. Alternaria spores can reach levels of thousands of spores per cubic meter of air in temperate areas from spring to fall. 70% of mold-allergic patients have IgE reactivity to Alternaria. A. alternata spores are especially high in the outdoor air during summertime. Alternaria alternata is an important allergen with mycelial fragments and airborne spores, these characteristics are accountable for the allergic symptoms in human with rhinitis, bronchial asthma or skin diseases.
We recommend to use the freeze dried medium (product code 09.01.31) for detection of IgE antibody in serum. The purity of the medium is much higher and contains the highest amount of Alt a 1, the major allergen of Alternaria alternata. Citeq produces moulds with shaking incubation. The product is the result of filtration of the mycelium and spores. This filtrated medium is concentrated, dialysed and freeze-dried. With this method the freeze dried medium contains only products produced by the moulds. It contains no medium and no spores. Due to concentration and dialysis there is a high amount of proteins in the product available.
We deliver Alternaria alternata in the following form:
- Medium (vial of 10mg) The medium of the mould extracted, the mould feeds on this medium.
