title: [Virulence and biochemical activity of Aspergillus fumigatus strains isolated from cow fetuses].
abstract: Tested was the virulence of 20 strains of Aspergillus fumigatus isolated from cow fetuses. All laboratory mice injected with them died, and the pregnant guinea pigs aborted. It was demonstrated that these strains contain exogenic and endotoxic substances which are extracted effectively with alcohol and ether. The mould cultures showed proteolytic, amylolytic, cellulose, and organic acid activity. The biochemical and pathogenic potential of the strains were of great importance for causing abortion.
