A 78-year-old male who was undergoing prolonged glucocorticoid treatment experienced cough and expectoration for 2 weeks. Galactomannan antigen analysis and a chest computed tomography (CT) scan suggested a diagnosis of invasive pulmonary aspergillosis. DNA sequencing indicated that Emericella nidulans var.

Diagnosis of invasive aspergillosis (IA) in immunocompromised patients using galactomannan ELISA (GM-ELISA) has shown variable sensitivity and specificity. To assess the diagnostic performance of GM-ELISA and analyze the effect of decreasing the cut off value, neutropenia, antifungals and piperacillin-tazobactam (PTZ).

The major noncellulosic polysaccharides and proteoglycans in the coffee bean (Coffea arabica) cell wall are (galacto)mannans and arabinogalactan proteins. Immunological and chemical probes demonstrated that the mannans and arabinogalactan proteins were located continuously across the width of the cell wall
