[Pathomorphological studies of spontaneous and experimental abortions in cows and guinea pigs].
The morphologic studies of aspergillosis abortions in cows and guinea pigs were carried out on 83 spontaneously affected aborted cattle fetuses, pregnant guinea pigs and their offsprings. Fifty-four fetuses were of spontaneously aborted cows from 12 farms along with 15 pregnant guinea pigs experimentally infected with Aspergillus fumigatus and a total of 14 fetuses of theirs. Microscopically, both in the cattle fetuses and in guinea pigs and their fetuses there were stasis, thrombosis, diapedetic hemorrhages, hyperplasia of the reticulohistiocytes, necrobiosis, and a good amount of polysaccharides in the investigated organs at the absence of hyalin in them. Special staining of cross sections of the studied viscera revealed hyphae of Aspergillus fumigatus--in the blood vessels and the tissue of the organs in spontaneously and experimentally infected, resp., aborted cattle fetuses as well as in guinea pigs but not in their fetuses.
