Abstract

A camel calf died shortly after it was translocated together with its mother from Pakistan to a farm in Dubai in the United Arab Emirates. Necropsy revealed severe alterations in the liver caused by bladder-like structures which appeared to be parasitic in nature and measured between 3–6 mm in size. Parasitological and histological examination showed structures resembling cysticerci at early stages of development. DNA sequencing of fragments amplified within the mitochondrial cytochrome c oxidase subunit 1 (cox1) and the NADH dehydrogenase subunit 1 (ND1) revealed that the infection had been caused by Cysticercus tenuicollis, the metacestode larval stage of Taenia hydatigena. The majority of the metacestode cysts of C. tenuicollis (30/36) observed at necropsy were in a stage of caseous degeneration which suggested that the dromedary may be an aberrant host of this parasite.
