A disease of axons.
- Boxer progressive a. — an inherited, degenerative disorder of the peripheral and central nervous system in Boxer dogs. By 6 months of age, dogs homozygous for the trait show ataxia and weakness in the hindlimbs and an absence of the patellar reflex.
- congenital a. — Holstein–Friesian calves are recumbent from birth; the necropsy lesion is degeneration in spinal cord and midbrain nerve tracts; considered to be inherited as an autosomal recessive trait.
- inherited ovine degenerative a. — inherited in several forms in some sheep breeds (Suffolk, Merino, Coopworth); may be congenital or develop at up to 6 months old; signs include ataxia, recumbency, invariable death. Probably the same disease as that called Murrurrundi disease.
- peripheral and central distal a. of Birman cats — see distal polyneuropathy of Birman cats.
- segmental a. — axonopathy affecting a segment of the axons.
