Antibodies against Aspergillus fumigatus. I. Standardization of the antigenic composition. 1980

H F Kauffman, and K de Vries

Three different stages were found during growth of Aspergillus fumigatus as characterized by the changes in pH of the medium: (1) An acidic phase (phase I); (2) a second phase (phase II) during which the pH rises till values around pH = 8.5; (3) a third phase (phase III) during which the pH remains constant or drops slightly. During phase I a fast appearance of certain antigenic components was found that is ascribed to an active process of excretion. Additional antigenic components appeared in the culture medium after lysis of the microorganisms (phases II and III). Lysis of the microorganisms and appearance of antigenic components are dependent on the glucose concentration of the medium.

UI	MeSH Term	Description	Entries
D007122	Immunoelectrophoresis	A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D006863	Hydrogen-Ion Concentration	The normality of a solution with respect to HYDROGEN ions; H+. It is related to acidity measurements in most cases by pH	pH,Concentration, Hydrogen-Ion,Concentrations, Hydrogen-Ion,Hydrogen Ion Concentration,Hydrogen-Ion Concentrations
D000908	Antibodies, Fungal	Immunoglobulins produced in a response to FUNGAL ANTIGENS.	Fungal Antibodies
D000946	Antigens, Fungal	Substances of fungal origin that have antigenic activity.	Fungal Antigen,Fungal Antigens,Antigen, Fungal
D001232	Aspergillus fumigatus	A species of imperfect fungi from which the antibiotic fumigatin is obtained. Its spores may cause respiratory infection in birds and mammals.	Aspergillus fumigates,Neosartorya fumigata,Sartorya fumigata
