“…According to Sharma and Chauhan (2006), this common location of the cyst causes the visual, behavioral and posture impairments that are the main clinical manifestations of coenurosis. A similar finding was reported by Rissi et al (2008).…”

“…Thus, the source of infection in this case is most probably identified. The clinical, macroscopic and microscopic findings were substantially similar to many other cases reported in the literature (RIET-CORREA et al, 1998;ACHENEF et al, 1999;SCOTT, 2007;RISSI et al, 2008).…”

“…For flock formation, matrices are usually imported from areas with long-standing tradition of sheep raising, mainly in Southern Brazil. The region of origin of the animal described in the present case report has a previous history of coenurosis in sheep and cattle (FERREIRA et al, 1992;RIET-CORREA et al, 1998;RISSI et al, 2008) and the disease is spreading to other Brazilian States (SOUZA et al, 2008). Thus, the source of infection in this case is most probably identified.…”

“…In chronic cases, the most common clinical signs are paralysis, blindness, nystagmus, lack of coordination, lethargy and lack of response to stimuli. Infected animals tend to move away from the herd and press their head against objects (EDWARDS; HERBERT, 1982;RISSI et al, 2008).…”

This paper reports the first case of coenurosis in the State of Mato Grosso do Sul, Brazil. This disease is caused by the larval stage of the tapeworm Taenia multiceps (Leske, 1780). The animal in which the disease was diagnosed was an 18-month-old ewe from an endemic area of Southern Brazil as an imported animal among a group of 30 sheep. The clinic-pathological condition was that commonly found in herbivores affected by the disease, especially sheep. Apathy, nystagmus, intermittent blindness, circling and pressing head against obstacles were the neurological signs reported. The necropsy showed that a brain lesion in the subcortex of the right hemisphere was a bladder-like cyst measuring 4 cm in diameter filled with a translucent fluid with a large number of white spherules (protoscolices) floating. In addition to the identification of the Coenurus cerebralis protoscolices, the brain tissue lesion was histopathologically described.

-year (1990-2007) database search in the files of the Laboratory of Veterinary Pathology (LPV) of the Universidade Federal de Santa Maria (UFSM), Rio Grande do Sul state, Brazil was carried out. In this period, 19,476 exams in domestic animals were done. Out of these exams, 6,816 (34.9%) were necropsies and 12,660 (65.1%) were performed in mailed samples from practitioners. Experimental cases were excluded from this study and corresponded to 54 necropsies and 15 histopathologic exams. After the exclusion 354 (5.1%) necropsies and 163 (1.2%) histopathologic exams were found in sheep. Out of these, 265 (74.8%) cases were conclusive in the group of necropsies and 96 (59%) were conclusive in the group of the histopathologic exams. The resulting 361 conclusive cases were grouped according to the etiology: 150 (41.6%) cases of poisoning or toxi-infections; 142 (39.3%) cases of infectious and parasitary diseases; 31 (8.6%) of metabolic and nutritional diseases; 13 (3.6%) cases of neoplasms and neoplasm-like lesions; 7 (1.9%) cases of diseases caused by physical agents; 6 (1.7%) cases of iatrogenic conditions; and 4 (1.1%) of developmental diseases. Eight cases did not fit in any of the above categories and were grouped under the denomination of other conditions. Hemonchosis and poisoning by Nierembergia veitchii were the most prevalent diseases in sheep during the 18 years of this study.INDEX TERMS: Diseases of sheep, pathology.

.br A retrospective study of neurological diseases of sheep in southern Brazil was conducted over an 18-year period (1990-2007). A data base search was carried out in the files of the Laboratory of Veterinary Pathology (LPV) of the Universidade Federal de Santa Maria (UFSM), central Rio Grande do Sul state, Brazil. A total of 586 sheep were examined. These cases corresponded to necropsies performed in the LPV-UFSM or to mailed in samples from practitioners. Out of these, 69 experimental cases were excluded from this study. The remaining 517 cases were composed of 361 (69.8%) cases with conclusive diagnoses and 156 (30.2%) cases with inconclusive diagnoses. In 58 (16%) occasions, sheep died in consequence of neurological disease. Most important diseases included coenurosis (15 cases or 25.8%), listeriosis (9 cases or 15.5%), tetanus (8 cases or 13.7%), vertebral abscesses (4 cases or 6.8%), and cerebral abscesses (3 cases or 5.1%). Poisoning by Erytroxylum argentinum, post-caudectomy suppurative myelitis, fibrinosuppurative meningoencephalitis, polioencephalomalacia, rabies (2 cases or 3.4% each) were occasionally diagnosed. Spinal cord demyelinization, encephalic white matter edema, focal symmetrical encephalomalacia, hydranencephalia, cerebellar hypoplasia, poisoning by organophosphate, poisoning by Solanum pseudocapsicum, fibrinosuppurative myelitis, and presumptive closantel toxicity (1 case or 1.7% each) were rarely seen.INDEX TERMS: Diseases of sheep, diseases of nervous system, neuropathology.
