North Queensland groper deaths blamed on marine bacteria

A DEADLY bacteria is believed to be at least partly behind the puzzling demise of more than 50 groper fish between Mackay and the Daintree River in north Queensland between 2007 and last year.

It is the first time Streptococcus agalactiae has been recorded in Australia. It also has been found in mullet, javelin grunter and stingrays.

Most groper deaths occurred near highly urbanised areas such as Cairns and Port Douglas, raising fears of a link between human environmental disturbance and emerging infectious diseases in wildlife populations.

Bats given anti-fungal treatments for white-nose

Researchers trying to slow the spread of a scourge that has killed more than a million bats are testing anti-fungal solutions in a hard-hit hibernation cave.

New York Department of Environmental Conservation researchers hope that topical anti-fungal agents applied to about 250 bats in an old iron mine on the edge of the Adirondacks will combat white-nose syndrome.

Unearthing Anthrax's Dirty Secret: Its Mysterious Survival Skills May Rely on Help from Viruses--and Earthworms

Using a pipette as a makeshift rolling pin, Raymond Schuch spent some of his lab time last summer pressing the guts out of earthworms that he had collected, fresh from Manhattan soil.

For his efforts, The Rockefeller University microbiologist extracted what looked like just a small pile of dirt, but was actually a microcosm teeming with phages—viruses that infect bacteria. Schuch was on the hunt for phages that could kill anthrax and become anti-anthrax therapies, but what he discovered were viruses that enable this deadly bacteria to grow and survive when the going gets tough.
