Hydatid echinococcosis (Echinococcus granulosus) in a laboratory colony of pig-tailed macaques (Macaca nemestrina).
Several cases of hydatid echinococcosis were diagnosed in a laboratory colony of 19 pig-tailed macaques (Macaca nemestrina) at the Paul Ehrlich Institute, Germany. Three hydatid cysts were found in the liver of an euthanized animal. The diagnosis of an Echinococcus granulosus infection was confirmed by histopathology and the results of a specific polymerase chain reaction. The serum of five of 14 other monkeys tested for Echinococcus antibodies using a genus-specific enzyme-linked immunosorbent assay (ELISA) was positive or weakly positive; none of the animals, however, showed specific reactions in a E. multilocularis-specific ELISA. On ultrasonographic examination, alterations in the liver were found in four of the serologically positive monkeys, and two animals showed clinical signs such as progressive anorexia, apathy and icterus. The monkeys had most probably acquired the E. granulosus infection in their breeding colony in Slovenia.
