STUDIES ON FUNGI ENCOUNTERED IN THE ATMOSPHERE .2. PRODUCTION OF DERMATITIS IN GUINEA PIGS BY CRUDE ETHER-SOLUBLE EXTRACTS OF ALTERNARIA, HORMODENDRUM, PENICILLIUM AND ASPERGILLUS

[摘要] Daily painting of crude ether extracts of alternaria, penicillium and aspergillus evoked eczematoid dermatitis in guinea pigs. No similar success was obtained with extracts of hormodendrum. Results of skin tests suggest the presence of primary irritants in the penicillium and aspergillus extracts and a possible contactant allergen in the alternaria extract.
