Macroscopic lesions in the foetuses.
A Abdominal haemorrhage in twin foetuses from a ewe challenged at 40 dpi. Notice the congestion in the foetal part of some placentomes. B Twins from a control, non-infected ewe from G1. C Twin foetuses from a challenged ewe in G2. Foetuses showed different degree of autolysis, suggesting that their dead occurred at different days post infection. D Aborted foetus from G2 showing maceration and also autolysis of the placenta.
