Orang-utan death could signal new zoonotic parasite
The death of an orang-utan at Milwauke Zoo could be due to a new zoonotic parasite scientists have warned.
The death of an orang-utan at Milwauke Zoo could be due to a new zoonotic parasite scientists have warned.

Rapid and severe progression raises concerns among scientists

The death of an orang-utan in Milwaukee Zoo could signal a new zoonotic parasite, scientists at the University of Wisconsin-Madison, have said.

Zoo keepers noted a loss of appetite in a juvenile Bornean orang-utan, named Mahal on December 29 2012. Two days later he was dead.

With an initial post mortem examination suggesting he died from acute respiratory disease due to a disseminated infection from an unknown parasite, scientists at the university set about using deep sequencing of total DNA.

Their conclusion was that Mahal's death may have been from a new parasite that may pose a risk to the heath of primates and other species.

"This animal's rapid and severe progression raises concerns about the health of captive apes in similar settings. Moreover, the close evolutionary relationship between orang-utans and humans raises concern about the parasite's zoonotic potential," said lead author Dr Tony Goldberg.

The report has been published online by the Centers for Disease Control and Prevention.
