Disease Likely Explanation For Mysterious Bird Deaths and other wildlife health news

Tue, 01 Jul 2014 05:30:00 +0000

TOP STORIES First diseased bat identified in Columbia areaA disease that is killing millions of bug-eating bats has shown up for the first time in Richland County, indicating the disorder could have broader impacts on the winged mammals than previously known.Recent laboratory tests confirmed white-nose syndrome in a bat from a site in the Columbia-area, according to the S.C. Department of Natural Resources.The discovery is significant because it indicates the possible spread of the disease away from the mountains and into other parts of South Carolina. That’s a concern, not only as a threat to the species itself, but because bats are natural exterminators.The State30 Jun 2014S Fretwell>>> FULL ARTICLEMore White-Nose Syndrome News >>> Will a bat-killing fungus make it to Texas?>>> UNH researchers taking part in white-nose syndromeScientists Close In On What’s Killing Sea StarsSome scientists see a connection between rising water temperatures and the wasting syndrome. The waters around the San Juan Islands tend to be colder than the Washington outer coastline where dying starfish were first reported last summer. Since the arrival of warmer weather this season, the syndrome has spread rapidly to areas like the San Juan Islands that were previously untouched by the syndrome. Recent reports have also surfaced of die-offs along Oregon's coastline.“The period of time in which the disease progressed rapidly has been a period in which waters have been warmer than usual winter conditions," Blanchette said.While scientists are reluctant to assign blame to climate change, Harvell explained that as oceans warm, outbreaks like this are more likely to occur."A warmer world would be a sicker world," Harvell said. "Under warming conditions a lot of microorganisms do better. They grow faster. They replicate faster. Many of our hosts can actually be stressed by warm conditions. And so it kind of creates a perfect storm of sickness."Jefferson Public Radio16 Jun 2014>>> FULL ARTICLEDisease Likely Explanation For Mysterious Bird DeathsThe sudden and inexplicable deaths of dozens of birds is probably linked to a disease, says an Icelandic ornithologist.“Everything points to a disease or some other contagion at work when many adult birds die within a short period of time,” said Gunnar Þór Hallgrímsson, an ornithologist and the director of the Southwest Iceland Nature Research Institute, to Vísir.Gunnar points out that in other countries, mass bird deaths are more common, and are usually the result of the bacteria Clostridium botulinum, better known as the organism which causes botulism.Reykjavik Grapevine17 Jun 2014P Fontaine>>> FULL ARTICLEOTHER WILDLIFE HEALTH RELATED NEWS Fungal disease kills Canton falcon chick [trichomoniasis][Ohio, USA]More Animals Found Dead Near Old Hickory Lake [Tennessee, USA]Beached whale found dead off island south of Phuket [Thialand]SUMMER SURVEY: Elk with severe hoof disease to be killed [Washington, USA]Study to document disease carrying ticks in AdirondacksLarge number of fish die in three rivers in Assam [India]Chronic wasting disease spreads in W.Va.

The study shows that tree bumblebees have rapidly spread despite them carrying high levels of an infection that normally prevents queen bees from producing colonies. The species arrived in the UK from continental Europe 13 years ago and has successfully spread at an average rate of nearly 4,500 square miles -- about half the size of Wales -- every year.Science Daily 03 Jun 2014>>> FULL ARTICLECited Journal ArticleCatherine M.

Millions of bats have died from this rapidly spreading disease and this new method allows for accurate detection of the disease without killing any more bats.Science Daily 29 May 2014>>> FULL ARTICLECited Journal ArticleGregory G.

But while most wildlife enthusiasts would prefer to handle living animals, Cooley has spent the past 35 years up to his elbows in the carcasses of dead deer, waterfowl or other creatures that have met their demise from unknown circumstances. As the Michigan Department of Natural Resources’ animal pathologist, Cooley’s job is to solve the mysteries of wildlife death.... The animals that end up in Cooley’s necropsy lab at Michigan State University come from the U.S. Fish and Wildlife Service, USDA Wildlife Services and the public. Sometimes, the cause of death is obvious. For example, an animal found on the side of the road with broken bones and bruises would likely have been hit by a car.Other times, the answer is not as straightforward.“You never know what you’re getting into,” said Julie Melotti, Cooley’s lab technician of seven years. “But sometimes you assume something is roadkill and it turns out to be something completely different.”Cooley and his staff of two veterinarians, two lab scientists and two technicians are responsible for investigating and reporting trends in animal health throughout the state. Their role is to predict the next epidemic and make suggestions for preventing it, if possible.“Wildlife health and human health, you can’t separate them. They are intertwined,” Cooley said. “The way people can travel and animals can travel, you can have a disease on the other side of the world and all of a sudden you find it in Michigan.”Detroit News 01 Jun 2014>>> FULL ARTICLEGenome Sequences Reveal How Lemurs Fight InfectionNew technique could aid conservation, disease surveillanceThe young lemur named Eugenius started to get sick. Very sick. He was lethargic, losing weight and suffering from diarrhea. Duke Lemur Center veterinarians soon pinpointed the cause of his illness: Eugenius tested positive for Cryptosporidium, a microscopic intestinal parasite known to affect people, pets, livestock and wildlife worldwide.In humans, thousands of cases of Cryptosporidium are reported in the United States each year, spread primarily through contaminated water.Since Eugenius was the first animal diagnosed in 1999, the parasite has caused periodic diarrhea outbreaks at the Duke Lemur Center. All of the infected animals are sifakas — the only lemur species out of 17 at the center known to fall prey to the parasite — and most of them were under age five when they got sick.Despite various efforts to stop the infection, such as quarantining infected lemurs and decontaminating their enclosures, more than half of the sifakas living at the center have tested positive for crypto at some point. While most animals recover, the pattern has veterinarians puzzled over why the outbreaks persist.Now, thanks to advances in next-generation sequencing technology, researchers are getting closer to understanding how these endangered animals fight the infection and detecting the illness early enough to minimize its spread.Red Orbit01 Jun 2014>>> FULL ARTICLECited Journal Article P.

Biologists Still Searching For Answers In Bald Eagle Deaths and other wildlife health news stories

Thu, 20 Mar 2014 05:30:00 +0000

TOP STORIESFish-Eating Ducks Hard Hit By Severe Winter, IceThe Niagara River corridor from Lake Erie to Lake Ontario is renowned as a spectacular winter haven for hundreds of thousands of water birds. But this year's bitterly cold season has made it notable for something else: dead ducks.Biologists say carcasses began piling up by the hundreds in early January after the plunging temperatures started icing over nearly the entire Great Lakes, preventing the ducks from getting to the minnows that are their main source of food. Necropsies on dozens of birds have confirmed the cause: starvation. "All have empty stomachs. They're half the weight they should be," said Connie Adams, a biologist in the state Department of Environmental Conservation's Buffalo office who has personally seen 950 dead birds."This is unprecedented. Biologists who've worked here for 35 years have never seen anything like this," she said. "We've seen a decline in tens of thousands in our weekly waterfowl counts." It's a phenomenon that has been seen elsewhere along the Great Lakes, with news reports of diving ducks and other waterfowl turning up dead by the hundreds along the southern part of Lake Michigan. They've also been found in Lake St. Clair between Lakes Erie and Huron.... Necropsies and toxicity analyses showed many of the Michigan ducks were subsisting on invasive zebra mussels, which caused the birds to have potentially toxic levels of selenium in their bodies, Mason said. Zebra mussels filter toxins from the water and pass them up the food chain.Most of the dead ducks seen in the upstate New York are red-breasted mergansers, which breed in northern Canada and Alaska and come south for the winter to the Great Lakes region. In most years, there are periods of freezing and thawing, providing enough breaks in the ice for them to dive for minnows.Monroe News 15 Mar 2014Location: Canada>>> FULL ARTICLEExperimental infection of house sparrows (Passer domesticus) with West Nile virus isolates of Euro-Mediterranean and North American origins...North American WNV outbreaks are often accompanied by high mortality in wild birds, a feature that is uncommon in Europe. The reason for this difference is unknown, but the intrinsic virulence of the viruses circulating in each continent and/or the susceptibility to the disease of Palearctic as opposed to Nearctic wild bird species could play a role.To assess this question, experimental inoculations with four lineage 1 WNV strains, three from southern Europe (Italy/2008, Italy/2009 and Spain/2007) and one from North America (NY99) were performed on house sparrows (Passer domesticus), a wild passerine common in both continents. Non-significant differences which ranged from 0% to 25% were observed in mortality for the different WNV strains.... Consequently, albeit being pathogenic for house sparrows, some Euro-Mediterranean strains had reduced capacity for replication in -and transmission from- this host, as compared to the NY99 strain. If applicable also to other wild bird host species, this relatively reduced transmission capacity of the Euro-Mediterranean strains could explain the lower incidence of this disease in wild birds in the Euro-Mediterranean area.7th Space19 Mar 2014>>> FULL ARTICLECited Journal ArticleJavier Del Amo et al.

TOP STORIES Crisis biology: Can bacteria save bats and frogs from deadly diseases?As populations plummet, biologists race for a solution.In 2007, Valerie McKenzie volunteered for a large study of human body bacteria. It was the dawn of the golden age of the microbe. Researchers were just beginning to understand how bacteria and other microbes in human intestines influence everything from obesity to allergies and infections. McKenzie, a University of Colorado-Boulder biologist, was mildly curious about her "microbiome." But she was more interested in the bacteria living on the skin of frogs and toads.Amphibian populations worldwide are plummeting, and entire species are going extinct. The West's struggling species include boreal toads and mountain yellow-legged frogs. Invasive species and habitat degradation play a major role, but amphibians are dying even in places with good habitat. Batrachochytrium dendrobatidis, an aggressive fungus commonly known as chytrid, is often to blame.McKenzie, who was studying the role of farmland conversion and suburbanization in the decline of leopard frogs in Colorado, suspected chytrid was also a factor. When she read a paper about a strain of bacteria found on red-backed salamanders that inhibited chytrid's growth, she began to wonder: What microbes lived on the skin of her frogs and toads?

TOP STORIES Partnership fights for ban on hunting with lead ammoCalifornia bill A.B. 711 requires the use of non-lead ammunition in all hunting of mammals, birds, and other wildlife. Audubon California, The Humane Society of the United Sates, and Defenders of Wildlife joined forces to get the bill passed.“Our three organizations worked together on a 2008 bill that limited use of lead ammunition in about 20% of California,” says Jennifer Fearing, California senior state director of The Humane Society of the United States. “A.B. 711 would extend this requirement to the rest of the state.”Garrison Frost, director of marketing and communications for Audubon California, says lead poisoning is a leading cause of death among wildlife that feeds on animals killed by lead ammunition. In addition, lead ammunition that seeps into the food chain, watershed, and overall environment poses a broader treat to human health.PR Week21 Feb 2014Tanya Lewis>>> FULL ARTICLERARE FERRETS NEED MORE LAND TO SURVIVE THE PLAGUEThe black-footed ferret is one of the most endangered mammals in North America, but new research suggests that these charismatic critters can persist if conservationists think big enough.Decades of human persecution (e.g., poisoning) of the ferret’s favorite prey, prairie dogs, and severe outbreaks of plague and distemper led to its extinction in the wild in 1987.Since then, thousands of captive-raised ferrets have been released across North America, and at least four wild populations have been successfully reestablished.However, a new factor threatens to undermine these hard-fought conservation gains: the continued eastward spread of the exotic bacterial disease plague, which is a quick and efficient killer of prairie dogs, and is caused by the same microbe that is implicated in the Black Death pandemics of the Middle Ages.Using a new multi-species computer modeling approach, researchers have linked models of plague, prairie dogs, and black-footed ferrets to explore the consequences of ecological interactions in ways not possible using standard methods.The results of this study, published in Journal of Applied Ecology, suggest that the continued survival of black-footed ferret populations requires landscapes larger than conservationists previously thought, and intensive management actions to reduce plague transmission.STONY BROOK UNIVERSITY21 Feb 2014 >>> FULL ARTICLEOTHER WILDLIFE HEALTH RELATED NEWSChesil Beach: Dead and oil-covered birds still washing up [England]Scientists to uncover secret life of ottersNecropsies on beached striped dolphins leave more questions than answers [Oregon, USA]Pneumonia plaguing southern Nevada bighorn sheepDeer harvest bounces back from viral outbreak [Delaware, USA]Large fish have disappeared from vast tracts of Australian coast, survey showsChronic wasting case investigation follows standard procedures [Wisconsin, USA]Chile: Owls drafted in to fight deadly hantavirusOne Health News CornerTicks Infected with Lyme Disease and New Pathogen Found in California Parks [USA]Research Prevents Zoonotic Feline Tularemia By Finding Influential Geospatial FactorsUpstream interventions may provide options to contain emerging pathogens at source Huh?!

Honeybee trade is hotbed for carrying disease into wild and other wildlife health news stories

Wed, 26 Feb 2014 02:41:00 +0000

Top StoriesStudy reveals new ways deadly squirrelpox is transmitted to red squirrelsNative red squirrels have declined throughout Britain and Ireland for the last century due to a combination of habitat loss and the introduction of the North American eastern grey squirrel. But more recently its few remaining populations have been devastated by an insidious pox virus passed to them by the alien invaders.A study by the biodiversity and conservation research centre Quercus at Queen's University Belfast (QUB), and published in the journal PLOS ONE, found the situation may be worse than previously thought as the disease appears to have multiple modes of potential transmission. The project was part-funded by the Northern Ireland Environment Agency (NIEA) through the Natural Heritage Research Partnership (NHRP) with Quercus, Queen's University Belfast and part-funded by the People's Trust for Endangered Species (PTES).Invading grey squirrels, which harbour the disease but typically do not suffer symptoms, may pass the virus in their urine. The research team conducted experiments to examine the survival of the virus outside the body in the wider environment, showing that it persists best in warm dry conditions. This raises the possibility that infected grey squirrels could pass on the disease by uninfected squirrels coming into contact with their dried urine during spring and summer.The virus was also found in the parasites of pox positive squirrels including fleas, mites and ticks, which are capable of carrying the disease between individuals or between the species.Eurekalert24 Feb 2014>>> FULL ARTICLEHoneybee trade is hotbed for carrying disease into wildHONEYBEES have been busy – spreading diseases to insects that pollinate crops. It seems imported honeybees are an important reservoir for viruses that kill wild pollinators, which could lead to a meltdown in the planet's pollination services.World trade in honeybee colonies contributes to honey production and also plays a vital role in agriculture – in some cases there would be no crop without the pollinators.Honeybee colonies in Europe and North America have suffered recent mysterious declines. But now it seems the colonies could be just as much of a threat to wild pollinators such as bumblebees and the many species of "solitary" bees.Matthias Fürst of Royal Holloway, University of London tracked the geographical prevalence in the UK of a non-native parasite called deformed wing virus (DWV) that is often found in both honeybees and bumblebees. The virus is spread by a mite and typically kills bees within 48 hours.

TOP STORIESMelting Arctic Ice Releases Deadly Seal ParasiteSarcocystis pinnipedi (dark purple) infecting the diaphragm of a ringed seal. There is no evidence of inflammation in the tissue, in contrast to infection in gray seal livers. Photo credit: Stephan Raverty | National Geogaphic. When wildlife pathologists arrived at Hay Island off the coast of Nova Scotia in March 2012, they met an eerie sight. Of the thousands of silver and black-speckled gray seals that lay on the rocky outcrop, roughly a fifth were dead, despite showing no outward signs of disease.Necropsies revealed that 406 dead seals were infested with a crescent moon-shaped parasite that had destroyed their livers, but it wasn't clear what the organism was or how the seals had contracted the parasite. Researchers revealed the parasite's identity here today at the annual meeting of AAAS, which publishes Science. They also explained how melting ice in the Arctic Circle is helping such pathogens disperse throughout the world's oceans.Science 14 Feb 2014E Underwood>>> FULL ARTICLEMore Arctic News >>> Is Climate Change Increasing the Disease Risk for Arctic Marine Mammals?

What's killing all the starfish on the West Coast? and other wildlife health news stories

Mon, 10 Feb 2014 06:30:00 +0000

TOP STORIES White-nose syndrome confirmed in bats in ArkansasWhite-nose syndrome, a fatal disease to several bat species, has been confirmed in Arkansas, the state Game and Fish Commission said Wednesday. The disease was documented in two northern long-eared bats found at a cave on a natural area managed by the Arkansas Natural Heritage Commission in Marion County, according to a news release.... Five bats were found to have the disease during a survey of the Marion County cave on Jan. 11. The fungus was confirmed by tests on two of the bats by the U.S. Geological Survey National Wildlife Health Center, according to an AGFC news release. The bats had damage to wing, ear and tail membranes consistent with white-nose syndrome.Arkansas News Bureau29 Jan 2014Arkansas, USA >>> FULL ARTICLEMore White-Nose Syndrome News>>> Bat fungus continues to concern biologists>>> Winter cave surveys track bat numbers, health [Kentucky, USA] >>> White Nose Syndrome May Be Unstoppable: Deadly Bat Disease Can Thrive in Caves Without BatsWhat's killing all the starfish on the West Coast?Starfish have been mysteriously dying by the millions in recent months along the West Coast, worrying biologists who say the sea creatures are key to the marine ecosystem.Scientists first started noticing the mass deaths in June 2013. Different types of starfish, also known as sea stars, were affected, from wild ones along the coast to those in captivity, according to Jonathan Sleeman, director of the U.S. Geological Survey's National Wildlife Health Center.... The most commonly observed symptoms are white lesions on the arms of the sea star. The lesions spread rapidly, resulting in the loss of the arm. Within days, the infection consumes the creature's entire body, and it dies.Entire populations have been wiped out in Puget Sound off the coast of Washington state, in the Salish Sea off Canada's British Columbia as well as along the coast of California. The mortality rate is estimated at 95 percent.... “What we currently think is likely happening is that there is a pathogen, like a parasite or a virus or a bacteria, that is infecting the sea stars and that compromises in some way their immune system,” Pete Raimondi, chair of the department of ecology and evolutionary biology, at the University of California, Santa Cruz, told AFP.San Jose Mercury News2014 Feb 02Jean-Louis SantiniWashington, and California, USA, and British Columbia, Cananda  >>> FULL ARTICLEAssorted South West parasites favour cleaner habitatBIOLOGISTS investigating parasites on freshwater fish in the South West believe they have discovered at least 42 native parasite species that were previously undescribed...Murdoch University Associate Professor Alan Lymbery, who presented the research at the WA Freshwater Fish Symposium, says two known introduced parasite species were found.In addition to the introduced species, 42 morphologically different native parasites appeared to be different species.... Dr Lymbery says 30–40 per cent of the parasites were only found in a single species of fish, which had serious implications for the parasite’s conservation risk if the fish was endangered.“[Parasites] are probably at more risk than the fish host species because although some of the parasites we found have a direct life cycle, which means that the fish is their only host, a large number of them also had an indirect life cycle, which means they rely on other hosts as well,” he says....

Battle For Bats: Surviving White Nose Syndrome

Battle For Bats: Surviving White Nose Syndrome was produced for the USDA Forest Service by Ravenswood Media. It shows how government and private agencies have come together to search for solutions to help our bat populations overcome WNS. The public can also play a role in the future of bats by providing habitat and surveying their populations. Bats are a critical component in a healthy forest ecosystem, plus they provide significant agricultural pest control and pollination. Their survival is essential for a sustainable natural environment.

TOP STORIESUA researchers trace bat killer's pathWhite-Nose Syndrome poses threat of extinction; potential impact on agriculture... The UA research identifies cold-loving, cave-dwelling fungi closely related to WNS, and where and how they spread, and how they survive. These findings help predict the future of North American bats —among them — the common Little Brown Bat, first seen with WSN in Ohio in March 2011.Led by Hazel Barton, UA associate professor of biology and recognized as having one of the world's preeminent cave microbiology labs, the research points to a group of fungi related to WSN, which appears as a white, powdery substance on the muzzles, ears and wings of infected bats and gives them the appearance they've been dunked in powdered sugar. Since it was first discovered in hibernating bats in New York in winter 2006-07, WNS has spread across 22 states, including Ohio. In Vermont's Aeolus Cave, which once housed 800,000 bats, WSN wiped out the hibernation den's entire population.In their research paper, "Comparison of the White-Nose Syndrome agent Pseudogymnoascus destructans to cave-dwelling relatives suggests reduced saprotrophic enzyme activity," published Jan. 22, 2014 by the PLOS ONE, Barton and UA post-doctoral fellow Hannah Reynolds compare two closely related fungi species and reveal common threads, including the discovery that the related fungi share the same nutritional needs.Originally satisfied by cave soil, the fungus' nutritional source has now transferred to bats. Barton and her colleagues are zeroing in on when the fungus transferred from environment to bat and the consequences of the fungus' relentless ability to survive solely in caves, uninhabited by bats.EurekAlert 29 Jan 2014>>> FULL ARTICLECited Journal ArticleReynolds HT, Barton HA (2014) Comparison of the White-Nose Syndrome Agent Pseudogymnoascus destructans to Cave-Dwelling Relatives Suggests Reduced Saprotrophic Enzyme Activity.

Likewise, animal shelters across the United States collected and shared blood samples from domestic cats.... In analyzing blood collected from wild and domestic cat populations in these regions, researchers identified the novel gamma herpes viruses in three species – and further discovered the bobcat virus in some mountain lions.

TOP STORIESBat-killing fungus lurks in the Kansas City areaA deadly fungus that has wiped out hibernating bats by the millions in its eight-year march west from a New York cave has finally crept into Jackson County.The discovery of “white-nose syndrome” in three tri-colored (or Eastern pipistrelle) bats in a limestone mine marks the nation’s westernmost spread, federal officials said last week. Afflicted mammals were found last winter in east-central Missouri; before that it was seen in the cave colonies of Pike County near the Mississippi River.22 Jan 2014 Kansas City Star D Levings>>> FULL ARTICLEReassortment patterns of avian influenza virus internal segments among different subtypesThe segmented RNA genome of avian Influenza viruses (AIV) allows genetic reassortment between co-infecting viruses, providing an evolutionary pathway to generate genetic innovation. The genetic diversity (16 haemagglutinin and 9 neuraminidase subtypes) of AIV indicates an extensive reservoir of influenza viruses exists in bird populations, but how frequently subtypes reassort with each other is still unknown.Here we quantify the reassortment patterns among subtypes in the Eurasian avian viral pool by reconstructing the ancestral states of the subtypes as discrete states on time-scaled phylogenies with respect to the internal protein coding segments. We further analyzed how host species, the inferred evolutionary rates and the dN/dS ratio varied among segments and between discrete subtypes, and whether these factors may be associated with inter-subtype reassortment rate. 7th Space24 Jan 2014>>> FULL ARTICLE Cited Journal ArticleLu LuSamantha J LycettAndrew J Leigh Brown.

Mosquito Abatement District Director Gary Hatch appeared before the Davis County Commission Tuesday expressing his concern. Hatch said he is not certain what effect the grebes infected with the West Nile virus may have on next summer's mosquito season, but there is the possibility the district could be facing a new strain of the virus in its effort to protect the public through its abatement sprayings.Testing has confirmed that more than 50 bald eagles died in Utah after scavenging on dead grebes that had the West Nile virus, the National Wildlife Health Center said.... But now district officials are concerned about where the grebes initially contracted the virus, and how it spread so quickly among that bird population."We know what killed the eagles," Hatch said. "But what happened with the grebes is the concern." Local officials suspect based on the evidence of positive test results that the grebes likely contacted the virus somewhere else along their migratory route.Standard-Examiner 22 Jan 2014B Saxton>>> FULL ARTICLEScientific Task Force on Avian Influenza and Wild Birds statement on: H5N8 Highly Pathogenic Avian Influenza in poultry and wild birds in Republic of Korea January 2014Current situationThe Republic of Korea reported its first of a numb[...]

Waterfowl poisoning halved by lead shot prohibition and more wildlife health news stories

Wed, 29 Jan 2014 06:30:00 +0000

TOP STORIES Micropredators dictate occurrence of deadly amphibian diseaseAn international team of researchers has made important progress in understanding the distribution of the deadly amphibian chytrid pathogen. In some regions, the deadly impact of the pathogen appears to be hampered by small predators, naturally occurring in freshwater bodies. These micropredators may efficiently reduce the number of free-swimming infectious stages (zoospores) by consuming them. This natural behavior will reduce the infection pressure on potential amphibian hosts and a goes a long way towards explaining the occurrence of chytridiomycosis, at least in temporal climatic regions. These results were published in the renowned scientific journal Current Biology. The team of researchers state that their results raise the hope of successfully fighting chytridiomycosis, nowadays one of the most deadly wildlife diseases.Phys.org21 Jan 2014>>> FULL ARTICLECited Journal ArticleDirk S.
