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

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