A comprehensive description is presented of four novel cases of
Four amorphic foetuses were delivered by three cows. Tissue samples were collected during autopsy, embedded in paraffin, sectioned, and stained with haematoxylin and eosin. Genomic DNA was isolated from tissue samples of abnormal foetuses and from blood leukocytes of their healthy siblings. PCR reactions were used to reveal the presence of Y-linked genes (SRY and AMELY) and an X-linked gene (AMELX).
All foetuses were classified to the group
Foetuses had monozygotic origin. Histological analysis showed a low level of development of tissues of meso- and ectodermal origin, as well as features of degrading patterns.
