title: [Studies of immunological activity of Aspergillus flavus Link. III. Presence of antibodies against fungal antigens in the sera of persons from selected groups].
abstract: The aim of this study was to determine the occurrence of antibodies against antigens of A. flavus (APP, AEM, AS, API), A. fumigatus and A. candidus. One hundred and fifty two sera of individuals connected with industrial environment were tested, in which A. flavus was permanently isolated: 339 sera of healthy controls-blood donors of city of Poznań, and 24 sera of patients with confirmed or suspected Aspergillosis were also included in the study. The sera were tested for a presence of specific antibodies by immunoprecipitation in 1% agar gel, by using inactivated sera and above mentioned antigens. In a group of people having permanent contact with A. flavus, antibodies to antigens derived from this genus were present in 4.6% of individuals while against A. fumigatus antigens in 0% and A. candidus 0.7%. In blood donors group 5 times lower percentage of sera having anti-A. flavus antibodies was found and a complete lack of detectable antibodies for other two genera. The results of the studies of patient sera indicate a necessity of broadening a set of fungal antigens used for an investigation of this type of sera. Antibodies against A. flavus were found in three patients and for A. fumigatus in 7 patients. One patient had antibodies for both genera and two patients had antibodies against A. flavus lacking antibodies against A. fumigatus. The results of this study indicate that antigens of A. flavus should be included into serodiagnosis of Aspergillosis.
