Notes:
Confocal scanning laser microscopy (CLSM), using CAAF(green) Fun1(red) stained biofilm. The red color of the FUN 1 cell stain was localized in dense aggregates in the cytoplasm of metabolically active cells. Thus, areas of red fluorescence represented metabolically active cells, and green fluorescence indicated cell wall-like polysaccharides, while yellow areas represented dual staining.

Conidial head and brown conidia in a section of a fungus ball caused by Aspergillus niger (H&E, x 400).

Double diffusion test for aspergillosis. Central well contains Aspergillus fumigatus antigen and wells in the top and bottom contain control antiserum.

Allergic Bronchocentric Granulomatosis. low power. Sections show muscle, lung with acute inflammation and evidence of organisation with early fibrosis. The bronchial wall can be seen with chronic inflammation and many eosinophils.There is a thickened basement membrane. No definite granulomata are seen.

Allergic Bronchopulmonary Aspergillosis (ABPA). PT JC
CXR prior to bronchoscopy had shown an opacity just superior to the right hilum, which was felt to represent possibly a fungal plug. Patient was therefore bronchoscoped.
