Coenurosis, a neurological parasitic infection of ruminants caused by the larval stage of Taenia multiceps, is commonly reported in Sardinia, the most representative region for ovine population in Italy. Chronic form appears as a consequence of cyst development, frequently reported in the brain and spinal cord. Diagnostic suspect of coenurosis is based on physical and neurological examination. The aim of this article is to describe physical, biochemical and cytological aspects of cisternal cerebrospinal fluid of 24 sheep with chronic coenurosis and to evaluate whether these alterations are helpful in the diagnosis of coenurosis. Cerebrospinal fluid was altered in 20 animals (83.3%). Increase of total protein was revealed in 7 animals (29.2%); an increase of total nucleated cell count was observed in 18 samples (75%). Cytological examination revealed mononuclear pleocytosis in 17 animals (70.1%). Eosinophils were observed in 16 animals in various degree (66.7%). Our results show that cerebrospinal fluid confirms signs of Central Nervous System inflammation in 20 animals out of 24 (83.3%) and in particular it was useful to identify a parasitic inflammation in 66.7% of the animals in which eosinophils were observed. Considering the results of this study, the very absence of significant neutrophilic pleocytosis could be considered useful to diagnose chronic cerebral coenurosis.
