“…A similar approach has been used to successfully treat intracranial abscesses in horses. 3,10 In the case described in the present report, antimicrobial treatment alone was inadequate, as evidenced by the deterioration in clinical condition during treatment with ceftiofur. The fusiform bacteria isolated from the abscess were susceptible to cephalosporins, so ceftiofur should have been a suitable antimicrobial.…”

A 1-month-old female alpaca weighing 15 kg (33 lb) was brought to the Queen' s Veterinary School hospital with a history of dullness, swaying, and head nodding that had become progressively worse over the previous week. The dam had been brought to the United Kingdom from Australia during the last month of pregnancy to join a herd of approximately 200. For 3 days following parturition, the cria was reportedly dull and maladjusted, but then became more responsive and suckled from the dam. Shortly after birth, the cria was given an injection of florfenicol-flunixin meglumine a (80 mg/kg [36 mg/lb], IM) by the referring veterinarian because of concerns about possible low-grade peritonitis.On initial examination, the cria remained in sternal recumbency with its head raised but swaying from side to side; signs of depression were evident. Rectal temperature was 37.3 o C (99.1 o F), pulse rate was 100 beats/min, and respiration rate was 32 breaths/min. Results of abdominal palpation and auscultation of the heart and lungs were unremarkable. The cria was reluctant to support its weight and had deficits in foot placement and hopping reactions in all 4 limbs. Flexor reflexes were normal in all 4 limbs, and strong patellar reflexes were present. Pupillary light reflexes and menace responses were normal. There was no evidence of pain associated with spinal palpation or manipulation. The abnormal mentation and involvement of all 4 limbs combined with an absence of cranial nerve deficits suggested a diffuse forebrain lesion or possible metabolic disorder. Case Description-A 1-month-old female alpaca was examined because of progressive clinical signs consistent with an intracranial lesion. Clinical Findings-Clinical signs included signs of depression, lethargy, tetraparesis, and neck weakness. Two large isointense intracranial masses could be seen on T1-weighted magnetic resonance images. On T2-weighted images, the masses contained concentric rings of hypointense and hyperintense material. Treatment and Outcome-2 abscesses were removed via a craniotomy that incorporated removal of the sagittal crest and surrounding skull and transection of the sagittal sinus. The bony deficit was replaced with polypropylene mesh. The alpaca recovered within 2 weeks and was fully integrated into the herd within 1 month after surgery. Clinical Relevance-Findings indicated that surgical removal is a feasible means of successfully treating intracranial abscesses in juvenile alpacas. (J Am Vet Med Assoc

“…Adult horses with cerebral abscesses demonstrated depression, blindness, ataxia, and decreased facial sensation and head tilt. 6,8,35 Diffuse meningitis, or multifocal infection, leads to more generalized signs of ataxia and depression perhaps including cranial nerve signs. Papilledema may be present due to increased intracranial pressure.…”

“…The diagnosis of brain abscesses by CT examination in living horses has been described and was used to guide therapy. 8,43,44 MRI of intracranial abscessation of horses has been described and appears to be a very useful diagnostic aid. 45,46 Nuclear scintigraphy using labeled autologous WBCs can also be attempted and may provide definitive evidence (Figure 14.2).…”

Summary Strangles, caused by the Gram‐positive bacteria Streptococcus equi subspecies equi (S. equi), is a highly contagious upper respiratory infection in horses. The infection is transmitted by inhalation or direct contact with mucopurulent discharge from an infected animal, resulting in fever, depression, and submandibular and retropharyngeal lymph node enlargement that can lead to respiratory distress. Complications include secondary cellulitis at external abscessation sites, guttural pouch empyema and its persistence into the carrier state, purpura haemorrhagica, metastatic abscessation, emergency tracheostomies and rarely secondary S. equi pneumonia or myositis. Control of outbreaks requires strict isolation protocols and hygiene measures. Detection methods of the index case and carrier state are constantly being refined to assist in the identification and prevention of disease perpetuation.
