Abstract
ABSTRACT: We reviewed the records of 5,083 cattle necropsies performed from January 1995 to December 2018 and filed at the Laboratory of Anatomic Pathology (LAP) of the “Universidade Federal de Mato Grosso do Sul” (UFMS). These necropsies were performed either by LAP-UFMS faculty (22.33%) or by field veterinary practitioners (77.67%) who subsequently submitted material for histological evaluation at the LAP-UFMS. Conclusive diagnoses were reached in 46.21% of the protocols (2,349 cases), and approximately 65% of the cases were classified as inflammatory or parasitic diseases, with rabies being the most diagnosed disease (20.82% of total conclusive diagnosis). There were a large number of protocols in which the diagnosis was of nonsuppurative meningoencephalitis of unknown cause (NSMUC). Those were the main differentials for rabies and bovine herpesvirus-5 necrotizing meningoencephalitis (NME); that is, the number of rabies cases may be even higher if one considers that many cases of NSMUC might be undiagnosed rabies cases. Toxic and toxic-infectious diseases were the second most prevalent category, and botulism cases represented 41% of this category. The other categories corresponded to less than 20% of the total diagnoses and were distributed in decreasing order of frequency as degenerative diseases (9.79%), diseases caused by physical agents (3.87%), other diseases (2.13%), neoplasms and tumor-like lesions (1.79%), metabolic or nutritional disorders (1.75%) and congenital malformations (0.64%). The large number of inconclusive diagnoses was mainly due to improper conditions of mailed-in material for histopathological evaluation, namely, nonrepresentative samples of all organs, autolysis, and the absence of epidemiological and clinical-pathological information.

Abstract
Foi realizado um estudo retrospectivo de janeiro de 2008 a dezembro de 2012 com base nos laudos de necropsia do Laboratório de Anatomia Patológica (LAP) da Faculdade de Medicina Veterinária e Zootecnia (FAMEZ), Universidade Federal de Mato Grosso do Sul (UFMS), com o intuito de descrever quais as doenças que afetam o sistema nervoso de bovinos que ocorrem no Mato Grosso do Sul. Os casos consistiam de acompanhados por técnicos do LAP e encaminhados por médicos veterinários que atuam no campo (autônomos ou do serviço veterinário oficial). De 1082 materiais analisados, 588 apresentavam histórico de sinais clínicos neurológicos. Destes, 341 (53,75%) tiveram diagnóstico correspondente a doenças neurológicas e 247 (46,25%) tiveram diagnóstico inconclusivos. As fichas clínico epidemiológicas foram revisadas para determinar dados referentes a epidemiologia, aos sinais clínicos e às alterações macroscópicas e microscópicas. O botulismo (16,67%), a raiva (15,92%), a polioencefalomalacia (8,05%) e a encefalite por herpesvirus bovino (4,31%) foram as enfermidade de maior frequência. Outras doenças como meningoencefalite não supurativa (2,62%), meningoencefalite supurativa (1,50%), abscessos cerebrais e osteomielite por compressão medular (1,31%), tétano (1,12%), hipotermia (0,94%), babesiose cerebral (0,75%), febre catarral maligna (0,37%) e lesões sugestivas de intoxicação por oxalato (0,19%) foram ocasionalmente diagnosticadas. Em nenhum dos casos foram observadas lesões que pudessem sugerir encefalopatia espongiforme bovina.
