- They indicate that there is damage to the nervous tissue further in.
- Should alert to the possibility of viral infection, which is a common cause of central nervous system disease.
- E.g. louping ill.
- Should alert to the possibility of viral infection, which is a common cause of central nervous system disease.
- The gut.
- An excessive number of lymphocytes diffusely infiltrating the lamina propria, often in conjunction with plasma cells, indicate an ongoing non-specific chronic enteritis.
- The respiratory tract.
- Peribronchial and peribronchiolar cuffing may occur to the point of actual lymphoid follicle formation in these areas.
- Follicles are sometimes large enough to cause partial occlusion of the airways.
- A feature of some chronic lung diseases.
- Ee.g. Mycoplasmosis in swine and calves.
- Peribronchial and peribronchiolar cuffing may occur to the point of actual lymphoid follicle formation in these areas.
- Diseases of the central nervous system.
