Two unusual organisms, Aspergillus terreus and Metschnikowia pulcherrima, associated with the lung disease of ankylosing spondylitis.

Two male patients with ankylosing spondylitis and upper lobe fibrosis and cavitation are described. A pneumonic disease in one was associated with mycological and serological evidence of infection with but no other aspergillus species. A large pulmonary mycetoma developed in the second patient and among a number of other fungal isolates was found the yeast The association of ankylosing spondylitis with bronchopulmonary aspergillosis is considered; is described for the first time as a human pulmonary pathogen, and the possible pathogenicity of in the debilitated human subject is discussed.
