Sažetak
Uprkos činjenici da neurološka oboljenja predstavljaju značajni deo interne medicine malih preživara, broj retrospektivnih studija njihove epizootiologije je do današnjeg dana ograničen. Ova studija prikazuje detaljan pregled epizootioloških podataka učestalosti neuroloških oboljenja ovaca i koza u Grčkoj. Studija je bazirana na podacima prikupljenim sa Klinike za farmske životinje, Fakulteta veterinarske medicine, A.U. Th od januara 2006. do maja 2011. Anamneza, rezultati kliničkih i neuroloških ispitivanja, kliničko-patološka i (ukoliko dostupna) patološka evaluacija su predstavljali minimum podataka koji su bili na raspolaganju. Bolesti nervnog sistema predstavljaju 37,9% i 19,2% od ukupnog broja ocenjenih slučajeva obolelih ovaca i koza. Najčešći neurološki poremećaji koji su dijagnostikovani kod ovaca su hronična cenuroza i skrepi, što čini 72 % slučajeva, zatim manje uobičajena stanja, kao što su Lentivirusni encefalomijelitis koza (OLE), listerioza i akutna cenuroza. Kod koza učestalost različitih vrsta neuroloških bolesti je više ravnomerno raspoređena, dok su listerioza i polioencephalomalacia neurološke bolesti sa kojima smo se najčešće susretali.
Abstract
Although neurological diseases comprise an important part of small ruminant internal medicine, the number of retrospective studies on their epidemiology conducted to date is limited. This study reports an extensive review of epidemiological data on the occurrence of neurological diseases in Greek sheep and goat herds. The survey was based on data retrieved from the records of the Farm Animal Clinic, School of Veterinary Medicine, A.U.TH from January 2006 to May 2011. Historical information, clinical and neurological examination, clinicopathological and (if available) pathological evaluation were the minimum data recorded in each case. Diseases of the nervous system represented 37.9% and 19.2% of the total evaluated sheep and goat caseload, respectively. The most frequent neurological disorders diagnosed in sheep were chronic coenurosis and Scrapie, which accounted for 72% of cases, followed by less common conditions like ovine lentiviral encephalomyelitis (OLE), listeriosis and acute coenurosis. In goats the frequency of various types of neurological diseases was more evenly distributed, with listeriosis and polioencephalomalacia being the most commonly encountered problems.
