Clinical and morphopathological characteristics of an enzootic occurrence of acute coenurosis (Coenurus cerebralis) in a XXXX herd.

@entity384 @entity2401 @entity742 @entity39
In this study, 30 @entity742 from a flock suddenly showed acute neurological symptoms associated with more than 30  % mortality. At necropsy, thickening associated with @entity384 and turbidity of meningeal membranes particularly on cerebellum, focal to multifocal @entity39 areas and whitish spots measuring 1 to 3  cm in diameter were observed in the cortex of cerebrum and cerebellum. Grossly, numerous white tracts were also observed in the myocardium. Histopathologically, the cross sections of coenurus larvae associated with @entity39 were observed. Multiple @entity39 areas were also observed in the gray matter of cerebellum due to migration of the larvae with an extensive infiltration of eosinophils and neutrophils. In the heart, multifocal granulomatous @entity2401 was diagnosed. No growth was seen in bacterial cultures of the brain and heart. Also, no bacteria were seen in these tissues stained with Ziehl-Neelsen and Brown-Brenn Gram stain. On basis of gross and histopathologic lesions, acute coenurosis was diagnosed. Unlike chronic coenurosis, acute form of the disease rarely reported in @entity742 .
