[ 2 / 3 ]

A 28-year-old man developed multiple episodes of fever, cough, shortness of breath, and leukocytosis several hours after cutting live oak and maple trees. Fungal cultures of wood chips from oak and maple trees were positive for Penicillium (three species), Paecilomyces sp., Aspergillus niger, Aspergillus sp., and Rhizopus sp. It was suggested that Penicillium sp. and Paecilomyces sp. shared cross-reactive antigens that were the significant antigens in the oak chips. The patient likely had hypersensitivity pneumonitis on exposure to Penicillium sp., when he was cutting trees. (Dykewicz 1988 ref.3016 7)
