SIGNALMENT: BREED: Italian Saddle. SEX: gelding. AGE: 11 years. MANTLE: bay. WEIGHT: 482 Kg. ATTITUDE: show jumping.
ANAMNESTIC INFORMATION
The Veterinarian reports, on the day following vaccination against Influenza and tetanus (adjuvant vaccine with immunostimulatory complex ISCOM, suspension for injection, in single dose), the onset of a systemic symptomatology, characterized by fever, depression, anorexia, generalized myalgia, jaundice, associated with neurological symptoms suggestive of involvement of the central nervous
system (apathy, alteration of mental state with depression of central nervous responses and disorientation, postural abnormalities, ataxia and incoordination of movements). This clinical picture is considered consequent to an adverse reaction to vaccination, and therefore reported to the Ministry of Health by completing and sending the appropriate Reporting Forms of Suspected Adverse Reaction. None of the other treated horses, in addition to the subject considered, showed a similar reaction. The reports indicates also that the symptomatology lasted for about 14 days, during which a symptomatic and supportive therapy was undertaken with partial improvement of the clinical conditions. However, depression, apathy, ataxia, and incoordination persisted, accompanied by a progressive weight loss. Therefore it was decided by the Veterinarian to confer the horse to the Department of Medicine of the Horse Veterinary Hospital of the University of Milan, Azienda "Polo Veterinario di Lodi" for further investigations.
PHYSICAL EXAMINATION
At the general examination, the subject showed fair nutrition conditions (Body Condition Score: 3/5, body weight: 482 kg). The skin and coat showed no alterations; the presence of a state of edema affecting the region of the distal shin and the hindquarters of both hind limbs was detected. The rectal temperature was 37.2° C and the mucous membranes appeared congest; the capillary filling time was less than 2 seconds. There was mild lymphadenomegaly of the right intermandibular lymph node. On palpation, arterial pulse was normal, with a frequency of 32 bpm. The cardiac stroke was perceivable
and, at the auscultation, the second tone was split; the heart rhythm was with no pericardial noises. At the functional examination of the breath, the respiratory frequency was 12 per minute, and the breath was normal. At the auscultation of the thorax, through the use of a respiratory bag, no anomalous lung
noises were found.
NEUROLOGICAL EXAM
The mental state was normal, but the sensory appeared depressed. An alteration of posture with the limbs articulated and swaying of the rear train with proprioceptive deficit, tetraparesis and widespread muscle tremors were detected. Upon examination of the region, a deficiency of the 5th, 7th and 8yh
pair of cranial nerves was detected (slight rotation of the head and low deviation of the bottom downwards, with a reduction of the sensitivity of the nasal septum and nostrils). The static
examination of the neck and front limbs showed a limit of sensitivity at the dorsal surface of the forearm, carpus and metacarpus. The static examination of the region of the trunk, the hind limbs, the anal region and the tail shows no significant changes. On the dynamic examination, a moderate bilateral weakness of the hind limbs (positive wave test) was found, with difficulty in repositioning and resistance to the traction of the tail, marked ataxia, which worsened with increasing gait (from step to

detectable for both t
