Wisconsin 06/18/13 therepublic.com: A man who was attacked by a black bear outside a cabin in northwestern Wisconsin is recovering at a hospital. The Wisconsin Department of Natural Resources says the man was attacked in his yard near Shell Lake on Monday night. DNR carnivore specialist David ShellLake_WIMacFarland says the man’s dog apparently initiated contact with the bear. MacFarland says the man’s brother came out of the cabin and shot and injured the bear, which ran away. The Burnett County Sheriff’s Department says the man was taken to a hospital in Shell Lake. He was then airlifted to a hospital in the Twin Cities. MacFarland says he’s in stable condition. DNR wildlife supervisor Mike Zeckmeister says officials have set up traps for the bear in case it returns.

New England 06/18/13 telegram.com: by Mark Blazis – Deer ticks are bad news. But we may soon be faced with an expanding population of one of their even more dangerous cousins. A Tufts Vet School Lyme disease authority, Dr. Sam Telford, shared that Lone Star ticks (Amblyomma americanum) — the major infectious villains from New Jersey south to Florida, west to Texas and Kansas, and up to Illinois — are now in Massachusetts and have been recorded as far north as Maine. With global warming, should we be surprised about hosting yet another southern invader? Maybe not — but we should be very concerned. In Dr. Telford’s words, “Lone Star ticks are very bad news.”

4ec92835b5a88b8e7531e7291b83c271LST’s transmit STARI, southern tick associated rash illness, a disease that mimics Lyme disease, as well as monocytic ehrlichiosis, Ehrlichia ewingii ehrlichiosis, rickettsiosis and tularemia. They are also suspected vectors of a recently recognized phlebovirus that caused two hemorrhagic fever cases in Missouri. There’s even speculation that LST’s can cause alpha gal, an allergy to red meat. Lone Star ticks are unusually aggressive, regularly moving considerable distances in pursuit of a blood host. Because their nymphs and larvae feed mainly on deer, Dr. Telford advises that we should encourage and support deer hunting to adequately manage our herds wherever they pose a problem.

Lone Star ticks tend to live in very specific habitats, notably where kudzu and bittersweet, two alien invasives, proliferate. Fortunately, at least for now, Telford notes, infestations of them fizzle out. Locally, the only stable populations are on Prudence Island in Rhode Island, Cuttyhunk, and Nashawena. Telford finds it odd that they’ve been there since the 1960’s and have not spread far into the surrounding mainland, though Long Island is now loaded with them. – For complete article see http://www.telegram.com/article/20130618/COLUMN10/106189831

Washington 09/17/12 spokesman.com: by Rich – Another five calves have been attacked by wolves at the Diamond M Ranch in Eastern Washington, bringing wolf-livestock conflicts to a tally of 15 in a short three-month period. Three calves were found dead last week and two more suffered severe injuries, according to ranch co-owner Bill McIrvin. The two calves that survived were discovered on Sept. 12 and 14. Both had suffered severe bites and torn flesh to their hindquarters. One of the calves had parts of her reproductive and urinary track torn from her body so she can no longer urinate properly.

The Diamond M, located in a portion of Eastern Washington known as the “Wedge”, has been working with the Washington State Department of Fish and Wildlife (WDFW) for several months to implement non-lethal methods to prevent damage to their cattle herd. Abiding with agency recommendations, the Diamond M waited to turn their calves out on summer range until they were 200 pounds. The ranch also employed more cowboys to patrol their grazing range. Despite these efforts, attacks to the herd have persisted resulting in a state confirmation of 10 dead and five injured since June.  The McIrvin’s herd records suggest there are likely a total of 40 dead from wolf attacks. – For complete report see http://www.spokesman.com/blogs/outdoors/2012/sep/17/more-dead-cattle-no-dead-wolve-reported-wedge/

Oregon 09/17/12 opposingviews.com: by Denise A. Justin – A woman who tried to help her friend save a cat that was choking on a mouse contracted Bubonic plague from the diseased feline, Portland health officials announced on Friday, September 14 . . . The woman, who wished to remain unidentified, was bitten at the same time as Paul Gaylord, who received national attention this summer when he almost died after contracting the infection (see posts in this blog dated June 13, 2012, and July 19, 2012). The 59-year-old Prineville man was hospitalized in critical condition with Black Plague on June 9 and spent nearly a month in intensive care on life support. “His heart stopped,” said his mother, Almeda Gaylord. “His lung collapsed. They told us he wasn’t going to make it.” On July 11, doctors announced that they would have to sever the top half of Gaylord’s fingers. They’ll also cut off the tips of his toes. Charlie, Gaylord’s cat, most likely was infected by a flea carrying the plague, officials concluded. The Oregon woman who was a “family friend” tried to help Gaylord when Charlie came home one day choking, with a mouse stuck in the back of his mouth. Gaylord tried to pull the mouse out and in the process, Charlie bit him and the woman. When they realized they couldn’t help the cat, Gaylord reportedly borrowed a gun from a neighbor and shot Charlie to stop his suffering, according to oregonlive.com. Public health officials sent the cat’s body to the federal Centers for Disease Control and Prevention. It confirmed that Charlie had the plague, said Emilio DeBess, state public health veterinarian. – For complete article see http://www.opposingviews.com/i/society/animal-rights/oregon-woman-contracts-black-plague-cat

National 08/30/12 discovery.com: Two men in Missouri who became severely ill after sustaining tick bites were found to be infected with a new type of virus, according to a study from the Centers of Disease Control and Prevention (CDC). Both men were admitted to hospitals after experiencing high fevers, fatigue, diarrhea and loss of appetite. They were originally thought to be suffering from a bacterial infection, but doubts arose when they didn’t improve after being treated with antibiotics. Further tests revealed their blood contained a new virus, which the researchers dubbed the Heartland virus. It belongs to a group called phleboviruses, which are carried by flies, mosquitoes or ticks, and can cause disease in humans. While the genetic material of Heartland virus appears similar to that of other phleboviruses, the particular proteins it produces are different enough to call it a new species, said study researcher Laura McMullan, a senior scientist at the CDC. Because the Heartland virus causes such general symptoms, it could be “a more common cause of human illness than is currently recognized,” the researchers wrote in the Aug. 30 issue of the New England Journal of Medicine. More studies are needed to identify the natural hosts of the virus, learn how many people are infected with it and find risk factors for infection, McMullan said. Because both men experienced tick bites shortly before they became ill — one man, a farmer, reported receiving an average of 20 tick bites a day — the researchers said it’s likely that the Heartland virus is spread by ticks, although more research is needed to confirm this. The new virus’s closest relative is another tick-borne phlebovirus, called SFTS virus, which was identified last year in China, and causes death in 12 percent of cases.

The Missouri men, who were both infected in 2009, recovered after 10 to 12 days in the hospital, although one of the men has reported recurrent headaches and fatigue in the two years since his hospitalization. The researchers suspect a species of tick commonly found in Missouri, called Amblyomma americanum, is one of the hosts of the Heartland virus. For now, taking precautions to prevent tick bites is the best way to avoid the virus, McMullan said. To prevent tick bites, the CDC recommends using repellents that contain 20 percent or more DEET, as well as avoiding wooded areas or areas with high grass.

National 08/29/12 reuters.com: by Sharon Begley – A total of 1,590 (human) cases of West Nile Virus, including 66 deaths, were reported through late August this year in the United States, the highest human toll by that point in the calendar since the mosquito-borne disease was first detected in the country in 1999, health officials said on Wednesday. The toll is increasing quickly. “We think the numbers will continue to rise,” said Dr. Lyle Petersen, director of the U.S. Centers for Disease Control and Prevention’s Division of Vector-Borne Infectious Diseases. Through last week, 1,118 cases and 41 deaths had been reported. The updated figures represent a 40 percent increase in the number of cases and a 61 percent spike in the number of deaths, but are short of the all-time record for a full year: 9,862 cases and 264 deaths in 2003. – See http://www.reuters.com/article/2012/08/29/us-usa-health-westnile-idUSBRE87S0WC20120829

Colorado 08/29/12 durangoherald.com: by Dale Rodebaugh – In the first confirmed (human) case of bubonic plague in the state since 2006, an Archuleta County resident has tested positive for the disease. The last human case in Archuleta County was in 1998. Although the investigation is ongoing, it is believed that the person contracted the plague during a family outing in the Cimarrona Campground northwest of Pagosa Springs, a news release from the San Juan Basin Health Department said. The department declined to give the gender or age of the victim.

Warning signs are being posted in the campground and environs in cooperation with the Colorado Department of Public Health and Environment and the U.S. Forest Service. The plague often spreads through rodent populations. – For complete article see http://www.durangoherald.com/article/20120829/NEWS01/708299897/Plague-case-reported-in-Archuleta-County
