[Experimental abortions in mice and guinea pigs caused by Aspergillus fumigatus spores].

Experiments were carried out with a total of 82 laboratory animals including 56 mice and 26 guinea pigs. The possibility was tested to provoke abortions in them with the use of Aspergillus fumigatus spores introduced through the trachea, orally or vaginally. The mould was isolated on Chapek agar from an aborted bovine fetus. It was found that all three routes of infection lead to abortions setting in after three to five treatments on the 1st to 3rd day following the last introduction of spores. The pregnant mice and guinea pigs showed individual sensitivity to the infection.
