Abstract

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 Aspergillus terreus 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 Metschnikowia pulcherrima. The association of ankylosing spondylitis with bronchopulmonary aspergillosis is considered; A. terreus is described for the first time as a human pulmonary pathogen, and the possible pathogenicity of M. pulcherrima in the debilitated human subject is discussed.
