New Study Finds Wild Pikas Are Natural Mammalian Hosts To H5N1 Avian Influenza Virus
Science Daily - www.sciencedaily.com
25 Aug 2009

For the first time a new study suggests that when exposed in their natural ecosystem, wild pikas (a species closely related to rabbits) are mammalian hosts of H5N1 subtype avian influenza viruses and may also be a source of transmission to domestic mammals and humans.

. . . In the study researchers traced the circulation of the H5N1 virus in wild pikas and confirmed a natural H5N1 virus infection in their native environment. Genetic testing of the H5N1 virus isolated in pikas revealed two distinct evolutionary groups, a mixed/Vietnam H5N1 virus sublineage (MV-like pika virus) and a wild bird Qinghai-like H5N1 sublineage (QH-like pika virus).

The West Nile virus has been found in three birds in Ocean County this summer, two coming last week, according to a report the state's Department of Health will release later this week.

It's the only county in the state where an infected bird has been reported.

The birds, blue jays, came from Brick and Manchester townships, said Leslie Terjesen, a spokeswoman for the Ocean County Health Department. Terjesen said 13 of the 62 statewide birds submitted for testing originated in Ocean County.


Viruses: Veterinarian in Australia Is Sickened After Being Exposed to a Rare Virus

A veterinarian in Australia has been hospitalized in critical condition after exposure to the rare Hendra virus, according to local reports, which said he fell ill after treating two dying horses on a Queensland stud farm.

The virus was found in 1994 and has never been seen outside Australia since its discovery in Hendra, a Brisbane suburb. There have been only a dozen outbreaks, but the virus has proved lethal to horses and to humans caring for them. About 70 percent of the horses infected have died, and so have three of the six people known to have caught it from them — a veterinarian, a farmer and a prominent horse trainer, according to the Australian Broadcasting Corporation.

Chinese lawmakers warned Tuesday of a "grave hidden peril" of epidemic animal disease because of inadequate monitoring facilities and a complex international environment.

Even though the government has set up a compulsory vaccination system, requiring immunization of animals against diseases harmful to people's health and the husbandry industry, the possibility of outbreaks of disease still existed, the lawmakers said in a report presented at the 10th session of the Standing Committee of the 11th National People's Congress (NPC).

Researchers report this week that they have found a surprising but reliable marker of colony collapse disorder, a baffling malady that in 2007-2008 killed off more than a third of commercial honey bees in the U.S.

Their study, in the Proceedings of the National Academy of Sciences, is the first to identify a single, objective molecular marker of the disorder, and to propose a data-driven hypothesis to explain the mysterious disappearance of American honey bees.

The team included researchers from the University of Illinois and the U.S. Department of Agriculture.




With Bat Extinctions Looming, 1.5 Million Dead, Group Says Feds Must Make Saving Bats First Priority

Mounting evidence that several species of bats have been all but eliminated from the Northeast due to a new disease known as white-nose syndrome prompted a conservation group to send a letter today to Sam Hamilton, the new director of the U.S. Fish and Wildlife Service, urging that action on the bat epidemic be his first priority.

In the letter, Kierán Suckling, executive director of the national, nonprofit Center for Biological Diversity, wrote: “…while we suspect you are still unpacking boxes in your new office, we feel compelled to spotlight a wildlife emergency of the highest order.

This crisis, the bat epidemic known as white-nose syndrome, cannot afford any delay before receiving your focused attention.”

Bat Killer: White Nose Syndrome [Video]

Since it was first observed in New York in 2006, a bat-killing infection known as white nose syndrome has spread across the Eastern Seaboard. More than a million bats of six different species have perished so far and infected caverns continue to be discovered. That's bad news since the fungus kills at least 90 percent of the bats it infects.

Even worse, the fungus may not be the culprit, but merely an opportunistic invader breaking out among bats already weakened by some other unknown factor.

Check out the fungus and efforts to fight the bat killer in this video:

Partial direct contact transmission in ferrets of a mallard H7N3 influenza virus with typical avian-like receptor specificity
7th Space - 7thspace.com

Avian influenza viruses of the H7 subtype have caused multiple outbreaks in domestic poultry and represent a significant threat to public health due to their propensity to occasionally transmit directly from birds to humans.

In order to better understand the cross species transmission potential of H7 viruses in nature, we performed biological and molecular characterizations of an H7N3 virus isolated from mallards in Canada in 2001.

Results. Sequence analysis that the HA gene of the mallard H7N3 virus shares 97 % identity with the highly pathogenic avian influenza (HPAI) H7N3 virus isolated from a human case in British Columbia, Canada in 2004.

Scientists are reporting encouragingly rapid coral growth on giant underwater steel cages – structures that they hope will help to regenerate battered reefs and improve protection of some vulnerable coastlines from rising sea levels.

Coral reefs support a quarter of life on Earth and last month David Attenborough warned that carbon dioxide is already above the levels that will condemn corals to extinction.

And while the metal cages, fed with electric current, are not a solution to the global problem of dramatically contracting reefs, they do appear to be providing promising results in small, local projects, and – in some cases – rescuing resorts where coral was vanishing fast.

Unique species on the Galápagos Islands are under threat from mosquitoes introduced by tourist planes and boats, according to research published today.

The southern house mosquito, Culex quinquefasciatus, capable of carrying West Nile fever and avian malaria, is being transported from mainland Ecuador and breeding with existing populations on the islands, prompting fears of disease outbreaks.

The Galápagos giant tortoise and marine iguana, which are unique to the archipelago, may now be at risk, say scientists from the University of Leeds and the Zoological Society of London (ZSL), who carried out the research in conjunction with the Galápagos national park and Charles Darwin Foundation.

Hypoxia, or lack of oxygen, in bottom waters is a well known environmental problem. New research at the University of Gothenburg, Sweden adds to the list of ill effects: hypoxia leads to increased levels of manganese, which damages the immune response in marine animals.

Water eutrophication and the resulting hypoxia is an ever-current issue, not least in connection with summer algal blooms.

A more recently acknowledged problem is that hypoxia, which occurs when algae is broken down, increases the release of toxic metals from bottom sediments. Researchers at the University of Gothenburg have found that one of these metals, manganese, may damage the immune response in marine animals.
