Diagnostic approaches for the main neurological diseases of ruminants and horses in Brazil

Abstract

The epidemiological, clinical, and pathological hallmarks of neurological diseases of ruminants and horses diagnosed in the Laboratory of Veterinary Pathology (LVP) of the Universidade Federal de Santa Maria (UFSM) are herein described. This paper is intended to work as a compiled database for practitioners or veterinarians working in diagnostic laboratories. Data was gathered from papers published by the LVP-UFSM faculty and staff or retrieved from the laboratory archives. The most important neurological diseases of cattle included rabies,hepatic encephalopathy due to ingestion of Senecio spp., meningoencephalitis by bovine herpesvirus, cerebral babesiosis, poisoning by Solanum fastigiatum, malignant catarrhal fever, and polioencephalomalacia. Sheep were affected mostly by coenurosis, meningoencephalitis by Listeriamonocytogenes, tetanus, encephalic or vertebral abscesses, and rabies. Goats were affected by meningoencephalitis by L. monocytogenes. Leukoencephalomalacia, trypanosomiasis by Trypanosomaevansi, and tetanus were important neurological diseases of horses.
