Aspergillosis

The opportunistic mold Aspergillus is the etiologic agent responsible for a variety of infections and conditions referred to as aspergillosis. These manifestations include a spectrum of diseases from allergic responses to the organism (allergic bronchopulmonary aspergillosis), to colonization with Aspergillus spp. (aspergilloma or fungus ball and other superficial conditions, such as external ear colonization) and invasive infection (invasive pulmonary aspergillosis and other clinical syndromes of tissue invasion).
