The posterior regions of the olfactory nasal mucosa of rats flown on Cosmos 1129 failed to reveal histopathological changes. These results are at variance with those of the Apollo 12 Biocore experiment in which severe necrotic olfactory mucosal lesions were seen in flight animals only. In the anterior aspect of the nasal cavity of the Cosmos 1129 rats, however, focal lesions of moderate severity and variable extent were seen. These were consistent in character with that of a mild virus infection, which, it is postulated, was self-limiting. The infection was present in all groups of animals: flight, synchronous and vivarium control.
