Infections caused by P aeruginosa belong to the class of opportunistic pathogens with frequent risk of infection in the hospital due to their high phenotypic diversity.24 Due to the current database's limitations, it is not yet known whether fungi and fungal allergens are relevant to the exacerbation of asthma.25 There is overwhelming evidence that the most common external triggers of asthma include fungi allergens.26 The diagnosis of a fungal allergy can be determined either by skin tests with antigens derived from fungi or by the measurement of specific IgE levels. The gene discussed is IGHE; the disease is asthma.
