An experimental treatment for Ebola has cured 100% of infected monkeys in a test.
The ZMapp drug was effective even when given five days after the animals displayed severe symptoms of the virus.
Two US doctors given the drug after being infected in Liberia have also recovered, but it is not know Zmapp was responsible or they were lucky.
At least two other patients treated with it have died.
The tests were conducted by scientists led by Gary Kobinger, from the Public Health Agency of Canada. He said: "ZMapp exceeds the efficacy of any other therapeutics described so far, and results warrant further development for clinical use."
"We hope that initial safety testing in humans will be undertaken soon, preferably within the next few months."
Out of 3,069 cases reported so far, thee have been 1,552 deaths.

EU foreign ministers yesterday accused Russia of invading eastern Ukraine and said Moscow should be punished with more sanctions.
Days after Nato claimed Russia had slipped 1,000 soldiers and heavy weaponry into Ukraine, the EU's top diplomats met in Italy to discuss the crisis.
Afterwards, Swedish Foreign Minister Carl Bildt said: "We see regular Russian army units operating on Ukrainian territory. We must call a spade a spade."
The diplomats are set to propose new sanctions for consideration today, but no official has said what form they would take.
The US and EU has already imposed sanctions on dozens of Russian officials, several firms and the country's finance sector. Moscow has retaliated by banning food imports.
Beyond the EU, US President Barack Obama said Russian support for rebel combatants in eastern Ukraine must incur "more costs and consequences".
Russia strongly denied it had invaded Ukraine, where fighting between State forces and rebels has claimed 2,200 lives.

Researchers at the University of Edinburgh have discovered six cases caused by bacteria similar to Mycobacterium lepromatosis, which causes leprosy, since 2006.
