      Adiaspiromycosis - a pulmonary disease of many species of rodents and occasionally of humans, caused by the inhalation of spores of the fungus Emmonsia parva and E. crescens. It is marked by huge spherules in the lungs, with symptoms ranging from the sub - clinical to a bilateral pneumonia.

      Adiaspore - a large, globose, thick-walled conidium, usually produced by Emmonsia (Chrysosporium) parvum, in the lungs of humans and animals.

      Aleurioconidium (pl. aleurioconidia) - a thallic conidium released by lysis or fracture of the supporting cell.

      Annellide - a specialized conidiogenous cell producing conidia in basipetal succession by a series of short percurrent proliferations (annellations). The tip of an annellide increases in length and becomes narrower as each subsequent conidium is formed.

      Ankylosing spondylitis is a form of chronic inflammation of the spine and the sacroiliac joints which are located in the low back where the sacrum meets the iliac bones; chronic inflammation in these areas causes pain and stiffness around the spine which overtime would lead to a complete cementing together of the vertebrae, a process called ankylosis which, in turn, results to total loss of spine mobility; Furthermore, it is also considered as a systemic rheumatic disease which can cause inflammation in other joints away from the spine, as well as other organs such as the eyes, heart, lungs, and kidneys.
