Résumé

One-day-old chicks were infected by aerosolized conidia ofAspergillus fumigatus orA. flavus. Plaques containing viable organisms were observed on the third day of infection. Although plaques persisted for several weeks, cultures could not be recovered from them after about ten days. Flourescent antibody methods revealed an immune response to both agents within three days of challenge. Precipitin titers againstAspergillus active protein (AAP) did not appear until the tenth day, and was not detected after seven weeks. Aspergillus polysaccharide (APS) failed to react antigenically in infected birds. AAP was separated by Sephadex chromatography into nine distinct fractions. One fraction from each species was associated with an immediate and one with a delayed type of skin response in wattles. A low molecular weight fraction which lacked skin reactivity was an effective antigen in precipitin tests. Except for a weak skin reaction toA. fumigatus APS in rabbits, skin tests with extracts and APP fractions correlated with wattle reactions in chicks.
