Adenomatosis of sheep's lungs
- 16 Downloads
Infectious adenomatosis of sheep's lungs (Jaagsiekte) was transmitted to two out of four sheep using material from diseased lungs which had been kept frozen for 52 months.
The infectious agent was sedimented twice in the ultracentrifuge in order to wash it of some soluble substances and in order to concentrate it slightly. The extract was inoculated directly into the lung, into the trachea and intranasally.
The experiment was terminated after 14 months and at that time typical lesions were found, but they were of small size and seemed to be at an early stage.
