Identification of Charcot-Leyden crystals by electron microscopy.
Charcot-Leyden crystals consist of a 13 000-molecular weight acidic protein whose amino acid composition distinguished it from the 9300-molecular weight major basic protein, the principal constituent of eosinophil large granules; this protein is identical to lysophospholipase (3) and is stained by basic fuchsin in the Ziehl-Neelsen method.
The minor criteria include asthma, unilateral predominance, radiographic bone erosion, fungal culture, Charcot-Leyden crystals, and serum eosinophilia.
