Koala gene map could help fight threat to species survival
More than 50 researchers in seven countries uncovered 26,558 koala genes in mapping the much loved marsupial’s DNA. They say it could help fight threats to the Australian icon, including from a chlamydia epidemic.

Scientists who have mapped the genome of Australia’s symbolic animal, the koala, say it could help them develop better vaccines to treat the animals, who are battling an epidemic of the bacterial disease chlamydia.
The development will also help scientists sidestep invasive procedures in investigating the biology of the marsupials, whose exact numbers are not known, but which wildlife groups estimate to range between 80,000 and 180,000.
Researchers at the Koala Genome Consortium, a team of 54 Australian and international scientists, said they sequenced more than 3.4 billion base pairs and more than 26,000 genes in the koala genome, which is slightly larger than the human one.
“We are in a great position now to be developing better vaccines to treat them,” said Katherine Belov, a professor of comparative genomics at the University of Sydney.
Belov and her colleagues published their search in the journal Nature Genetics on Monday.
