Correlative Magnetic Resonance Imaging and Histopathology in Small Ruminant Listeria Rhombencephalitis.

Listeria rhombencephalitis, infection of the brainstem with , occurs mainly in humans and farmed ruminants and is associated with high fatality rates. Small ruminants (goats and sheep) are a large animal model due to neuropathological similarities. The purpose of this study was to define magnetic resonance imaging (MRI) features of listeria rhombencephalitis in naturally infected small ruminants and correlate them with histopathology.

Metabolic profiling of listeria rhombencephalitis in small ruminants by H high-resolution magic angle spinning NMR spectroscopy.

Listeria rhombencephalitis is caused by infection with Listeria monocytogenes and is associated with a high mortality rate in humans and ruminants. Little is known about the metabolic changes associated with neurolisteriosis in particular and infectious central nervous system (CNS) diseases in general. The purpose of our study was to investigate the metabolic changes associated with listeria rhombencephalitis in small ruminants (goats and sheep) as a model for inflammatory CNS disease by H high-resolution magic angle spinning nuclear magnetic resonance ( H HR-MAS NMR) spectroscopy of brain biopsies obtained from the brainstem and thalamus.

Does systemic lidocaine reduce ketamine requirements for endotracheal intubation in calves?

Objective: To investigate whether an intravenous (IV) lidocaine bolus in calves premedicated with xylazine-butorphanol reduces the amount of ketamine required to allow endotracheal intubation.

Study Design: Randomized, prospective clinical study.

Animals: In total, 41 calves scheduled for elective umbilical surgery.

MAGNETIC RESONANCE IMAGING FINDINGS IN SMALL RUMINANTS WITH BRAIN DISEASE.

Brain disease is an important cause of neurologic deficits in small ruminants, however few MRI features have been described. The aim of this retrospective, case series study was to describe MRI characteristics in a group of small ruminants with confirmed brain disease. A total of nine small ruminants (six sheep and three goats) met inclusion criteria.
