[Epizootologic study of aspergillosis abortions in cows].
Studied were mycologically a total of 463 aborted fetuses from 32 farms in the district of Roussé in 1972-1974. The pathogenic Aspergillus fumigatus fungus was established in 16.19 per cent of the cases. Abortions occurred the year round, becoming more frequent on the hot and wet days in summer and autumn as well as at in-door rearing and inappropriate hygiene conditions in winter. Most frequently abortions set in between the third and seventh month of pregnancy, which should be taken into consideration in diagnosing the disease.
