Nine monkeys who died in Hong Kong's oldest zoo in two days this week had been infected with an endemic disease, possibly after some digging work near their cages, officials said on Friday.

Secretary for Culture, Sports and Tourism Kevin Yeung said in a press briefing that the animals in the Hong Kong Zoological and Botanical Gardens contracted melioidosis and the disease later caused them to develop sepsis, according to The AP.

Yeung stressed that such infections typically occur through contact with contaminated soil and water and that there is generally no danger to humans from contact with infected animals or people.

“We're saddened by the passing of the nine monkeys,” he said.

Eight monkeys were found dead on Sunday, and another died Monday after displaying unusual behavior. The deceased animals were a De Brazza’s monkey, a common squirrel monkey, four white-faced sakis and three cotton-top tamarins — a species listed as critically endangered by the International Union for Conservation of Nature.

According to Hong Kong's Center for Health Protection, melioidosis is caused by the bacterium Burkholderia pseudomallei, which is widespread in soils and muddy water.

Yeung said the park conducted digging work to repair some irrigation pipes under the flower bed near the monkey cages in early October and that the deaths might be related to that.

He said the monkeys might have come into contact with the bacteria after the park's staff walked into their cages with possibly contaminated shoes. Another possibility is that some infected monkeys had close contact with other monkeys, he said.

“The incubation period for melioidosis in primates is about a week and this matched with the period after the soil digging work,” he said.

Edwin Tsui, the controller of the center, said the incident only happened in a single zone and its impact on Hong Kong residents would be very low.

Yeung on Monday held an urgent interdepartmental meeting about the deaths with the Leisure and Cultural Services Department, the Agriculture, Fisheries and Conservation Department and the Department of Health.

Another De Brazza’s monkey also displayed unusual behavior and appetite but offiicials said its condition remained stable on Friday.

The Hong Kong Zoological and Botanical Gardens — the oldest park in the former British colony — fully opened to the public in 1871. It is a rare urban oasis in the downtown Central district of the financial hub, which returned to Chinese rule in 1997.

A half-ton Soviet spacecraft that never made it to Venus 53 years ago is expected to fall back to Earth this weekend.

Built to land on the solar system's hottest planet, the titanium-covered spacecraft may survive its fiery, uncontrolled plunge through Earth's atmosphere, predicted to occur on Saturday. But experts said it likely would come down over water, covering most of the world, or a desolate region.

The odds of it slamming into a populated area are “infinitesimally small,” said University of Colorado Boulder scientist Marcin Pilinski.

“While we can anticipate that most of this object will not burn up in the atmosphere during reentry, it may be severely damaged on impact,” Pilinski said in an email.

By Friday, all indications pointed to a reentry early Saturday morning, US Eastern Time, give or take several hours. While space debris trackers around the world converged in their forecasts, it was still too soon to know exactly when and where the spacecraft known as Kosmos 482 would come down. That uncertainty was due to potential solar activity and the spacecraft’s old condition. Its parachutes were expected to be useless by now and its batteries long dead.

Dutch scientist Marco Langbroek estimated the impact speed at 150 mph (242 kph) if the spacecraft remains intact.

The Soviets launched Kosmos 482 in 1972, intending to send it to Venus to join other spacecraft in their Venera program. But a rocket malfunction left this one stuck in orbit around Earth. Gravity kept tugging on it and was expected to finally cause its doom.

Spherical in shape, the spacecraft — 3-foot (1-meter) across and packing more than 1,000 pounds (495 kilograms) — will be the last piece of Kosmos 482 to fall from the sky. All the other parts plummeted within a decade.

Any surviving wreckage will belong to Russia under a United Nations treaty.
