Cystic Echinococcosis also known as 'Hydatidosis' is significant helminthic zoonoses that continue to be an important problem in terms of animal as well as public health. A twelve years old, Holstein Friesian crossbred cow was presented to the Veterinary Polyclinic, Lalhri, District Una, Himachal Pradesh for post-mortem examination. External examination revealed pale-yellow mucous membranes with cachexia. Internal examination revealed the presence of variable numbers and sizes of monolocular and multilocular hydatid cysts affecting the vital organs viz. lungs, liver, and spleen. On cut sections, the cysts were also found deeply embedded within the parenchyma and containing protoscolices inside the fluidfilled cavity. Histopathologically, the affected organs revealed moderate to severe congestion, mononuclear cell infiltration, extensive fibrosis, degeneration, and atrophic changes in the parenchyma adjacent to the cyst. The present investigation reports an event of cystic echinococcosis affecting multiple organ systems leading to the death of cattle in Himachal Pradesh, India.
