The occurrence of and organisms concerned with bovine mycotic abortion in some counties of Ireland.

Bovine mycotic abortion in some counties of the Irish provinces of Leinster and Ulster was estimated at 1-2% of all abortions for which a causal agent was identified in the years from 1969 to 1978. The organism most commonly isolated from diseased specimens was Aspergillus fumigatus, followed by Absidia corymbifera. There was no relationship between the incidence of the disease in any year and the rainfall or number of raindays during the previous summer. The data obtained are discussed in relation to the occurrence of the disease in the United Kingdom.
