Early-Onset Progressive Retinal Atrophy Associated with an IQCB1 Variant in African Black-Footed Cats (Felis nigripes).

African black-footed cats (Felis nigripes) are endangered wild felids. One male and full-sibling female African black-footed cat developed vision deficits and mydriasis as early as 3 months of age. The diagnosis of early-onset progressive retinal atrophy (PRA) was supported by reduced direct and consensual pupillary light reflexes, phenotypic presence of retinal degeneration, and a non-recordable electroretinogram with negligible amplitudes in both eyes.

Corneal Emergencies.

Corneal emergencies can be due to a number of different causes and may be vision threatening if left untreated. In an attempt to stabilize the cornea, it is of benefit to place an Elizabethan collar on the patient to prevent further corneal damage. This article discusses the diagnosis, prognosis, and management of corneal emergencies in dogs and cats.

Diagnosis of deafness in a horse by brainstem auditory evoked potential.

Deafness was confirmed in a blue-eyed, 3-year-old, overo paint horse by brainstem auditory evoked potential. Congenital inherited deafness associated with lack of facial pigmentation was suspected. Assessment of hearing should be considered, especially in paint horses, at the time of pre-purchase examination.

Malignant neoplasia in four alpacas.

Malignant neoplasia in 4 alpacas was characterized by acute onset of clinical signs and rapidly deteriorating condition. Postmortem examination revealed metastatic or multicentric neoplasia in the abdominal organs of alpacas 1, 3, and 4 and an extensive thoracic mass in alpaca 2. Immunohistochemical stains supported a diagnosis of B-cell lymphosarcoma in alpacas 1-3 and a neuroendocrine neoplasm in alpaca 4.

Evaluation of bovine viral diarrhea virus in New World camelids.

Objective: To determine the effect of experimental infection with bovine viral diarrhea virus (BVDV) on llamas and their fetuses, evaluate seroprevalence of BVDV in llamas and alpacas, and genetically characterize BVDV isolates from llamas.

Design: Prospective study.

Animals: 4 pregnant llamas for the experimental infection study and 223 llamas and alpacas for the seroprevalence study.

Analysis of synovial fluid from clinically normal alpacas and llamas.

Objective: To establish reference range values for synovial fluid from clinically normal New World camelids.

Animals: 15 llamas and 15 alpacas.

Procedure: Llamas and alpacas were anesthetized with an IM injection of a xylazine hydrochloride, butorphanol tartrate, and ketamine hydrochloride combination.
