P.E.I. vet says isolation and testing key to stopping spread of strangles

(Anna MacDonald/AVC – image credit) A P.E.I. vet is recommending isolation and testing as keys to stopping the spread of strangles. Two P.E.I. horses tested positive last week, one at the Red Shores Racetrack in Charlottetown and another at the Shamrock Training Centre in Ontario. It had just been transported from Red Shores on Sunday, Feb. 14. Dr. Ben Stoughton, large animal medicine clinician at the Atlantic Veterinary College, said strangles is highly contagious. “I typically explain strangles as being strep throat of horses, just like people get strep throat and a sore throat and can have a fever and feeling badly,” Stoughton said. “Similar to people, they may get a fever, they may have a sore throat, have difficulty swallowing. They could get swollen lymph nodes that you can palpate and can also have stuff coming out of their nose.” Taking temperature and testing Since the first outbreak at Red Shores in Charlottetown in November 2020, the Atlantic Provinces Harness Racing Commission recommended horse owners at Red Shores locations in Charlottetown and Summerside monitor their animals’ temperatures twice daily. “We’re looking for a fever,” Stoughton said. “As the body tries to fight infection, like in this case, it’s a bacterial infection, the body responds by increasing the temperature, which can be measured with a thermometer.” Dr. Stoughton said a sample is collected from a horse exhibiting symptoms by sticking a tube up its nose and washing out the area with a saline solution, collecting it in a cup and culturing it. Stoughton said a sample is collected from a horse exhibiting symptoms by sticking a tube up its nose and washing out the area with a saline solution, collecting it in a cup and culturing it. He said they also use a PCR, or polymerase chain reaction, test to detect DNA of bacteria, a kind of test also being used for COVID-19. Identification of bacteria can be performed in minutes using the MALDI-TOF Mass Spectrometer in the AVC Diagnostic Services’s bacteriology lab. Stoughton said it’s crucial to isolate horses as quickly as possible once they have shown symptoms. “Because the bacteria that causes this is very contagious among horses, so it’s easily spread from nose to nose, or even contact with people,” Stoughton said. “If they have a nasal discharge that has the bacteria in it, it gets on the environment, gets on a person, and then a horse goes and actually licks that, or smells that, and they get it back up into their nose. That’s how it would spread.” Dr. Ben Stoughton, large animal medicine clinician at the AVC, said strangles is highly contagious. Stoughton said that’s why the biosecurity measures now in place at Red Shores are important, including wearing gloves, disinfecting horse gear, disinfecting the feed and water tubs and limiting the people in and out of barns in quarantine. He said the majority of sick horses only need supportive care, but will occasionally need antibiotics if the horses have a severe obstruction. “They call it strangles because the lymph nodes that get infected with this bacteria can get so large that they actually obstruct the ability for the horse to breathe,” Stoughton said. “So that’s how it got the name strangles because they can get so swollen that the horse can’t race.” Signage at Red Shores Racetrack aimed at restricting acccess to the barn area. Most horses recover Stoughton said strangles is not widespread, but also not uncommon. “If you have horses, mules, ponies, donkeys, anywhere in the world, you’re going to eventually have this bacteria pop up,” Stoughton said. “But thankfully, it’s not bad outbreaks all the time, but it wouldn’t be surprising to have it occur once a year, once every other year, depending on where you are in the world.” Dr. Stoughton said the infection spreads through close contact. These horses do not have strangles but demonstrate the kind of nose to nose contact that can lead to transmission. Stoughton said a very low percentage of horses die from strangles, and most will recover in two to three weeks. He said they only start testing to confirm that the horse is no longer a carrier three weeks after the last clinical signs. In the Atlantic provinces, the harness racing commission requires three negative tests for strangles before a horse is cleared for racing. The harness racing season is finished for now at Red Shores Racetrack, resuming in May. Stoughton said if they only did one test, they could miss some of the bacterial organisms. “We’re less likely if you do it three consecutive times to miss a carrier horse,” Stoughton said. “It’s important that we not miss the carrier horse, because if we call that horse negative and it’s technically positive, then that horse gets put out with other horses, and then could restart the problem all over again. So it’s just to be extra cautious.” Red Shores Racetrack has taken measures to prevent the spread of strangles, including adding security and restricting who can enter the barns. Stoughton said there have been occasional reports of this bacteria spreading to humans, in people that have immune suppression. He said the main concern with humans is that they would get the bacteria on their body or hands, and spread it from horse to horse. More from CBC P.E.I.

Here’s how Helene and other storms dumped a whopping 40 trillion gallons of rain on the South

Published

 on

 

More than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it — an unheard of amount of water that has stunned experts.

That’s enough to fill the Dallas Cowboys’ stadium 51,000 times, or Lake Tahoe just once. If it was concentrated just on the state of North Carolina that much water would be 3.5 feet deep (more than 1 meter). It’s enough to fill more than 60 million Olympic-size swimming pools.

“That’s an astronomical amount of precipitation,” said Ed Clark, head of the National Oceanic and Atmospheric Administration’s National Water Center in Tuscaloosa, Alabama. “I have not seen something in my 25 years of working at the weather service that is this geographically large of an extent and the sheer volume of water that fell from the sky.”

The flood damage from the rain is apocalyptic, meteorologists said. More than 100 people are dead, according to officials.

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just Georgia, Tennessee, the Carolinas and Florida from Hurricane Helene.

Clark did the calculations independently and said the 40 trillion gallon figure (151 trillion liters) is about right and, if anything, conservative. Maue said maybe 1 to 2 trillion more gallons of rain had fallen, much if it in Virginia, since his calculations.

Clark, who spends much of his work on issues of shrinking western water supplies, said to put the amount of rain in perspective, it’s more than twice the combined amount of water stored by two key Colorado River basin reservoirs: Lake Powell and Lake Mead.

Several meteorologists said this was a combination of two, maybe three storm systems. Before Helene struck, rain had fallen heavily for days because a low pressure system had “cut off” from the jet stream — which moves weather systems along west to east — and stalled over the Southeast. That funneled plenty of warm water from the Gulf of Mexico. And a storm that fell just short of named status parked along North Carolina’s Atlantic coast, dumping as much as 20 inches of rain, said North Carolina state climatologist Kathie Dello.

Then add Helene, one of the largest storms in the last couple decades and one that held plenty of rain because it was young and moved fast before it hit the Appalachians, said University of Albany hurricane expert Kristen Corbosiero.

“It was not just a perfect storm, but it was a combination of multiple storms that that led to the enormous amount of rain,” Maue said. “That collected at high elevation, we’re talking 3,000 to 6000 feet. And when you drop trillions of gallons on a mountain, that has to go down.”

The fact that these storms hit the mountains made everything worse, and not just because of runoff. The interaction between the mountains and the storm systems wrings more moisture out of the air, Clark, Maue and Corbosiero said.

North Carolina weather officials said their top measurement total was 31.33 inches in the tiny town of Busick. Mount Mitchell also got more than 2 feet of rainfall.

Before 2017’s Hurricane Harvey, “I said to our colleagues, you know, I never thought in my career that we would measure rainfall in feet,” Clark said. “And after Harvey, Florence, the more isolated events in eastern Kentucky, portions of South Dakota. We’re seeing events year in and year out where we are measuring rainfall in feet.”

Storms are getting wetter as the climate change s, said Corbosiero and Dello. A basic law of physics says the air holds nearly 4% more moisture for every degree Fahrenheit warmer (7% for every degree Celsius) and the world has warmed more than 2 degrees (1.2 degrees Celsius) since pre-industrial times.

Corbosiero said meteorologists are vigorously debating how much of Helene is due to worsening climate change and how much is random.

For Dello, the “fingerprints of climate change” were clear.

“We’ve seen tropical storm impacts in western North Carolina. But these storms are wetter and these storms are warmer. And there would have been a time when a tropical storm would have been heading toward North Carolina and would have caused some rain and some damage, but not apocalyptic destruction. ”

‘Big Sam’: Paleontologists unearth giant skull of Pachyrhinosaurus in Alberta

Published

 on

 

It’s a dinosaur that roamed Alberta’s badlands more than 70 million years ago, sporting a big, bumpy, bony head the size of a baby elephant.

On Wednesday, paleontologists near Grande Prairie pulled its 272-kilogram skull from the ground.

They call it “Big Sam.”

The adult Pachyrhinosaurus is the second plant-eating dinosaur to be unearthed from a dense bonebed belonging to a herd that died together on the edge of a valley that now sits 450 kilometres northwest of Edmonton.

It didn’t die alone.

“We have hundreds of juvenile bones in the bonebed, so we know that there are many babies and some adults among all of the big adults,” Emily Bamforth, a paleontologist with the nearby Philip J. Currie Dinosaur Museum, said in an interview on the way to the dig site.

She described the horned Pachyrhinosaurus as “the smaller, older cousin of the triceratops.”

“This species of dinosaur is endemic to the Grand Prairie area, so it’s found here and nowhere else in the world. They are … kind of about the size of an Indian elephant and a rhino,” she added.

The head alone, she said, is about the size of a baby elephant.

The discovery was a long time coming.

The bonebed was first discovered by a high school teacher out for a walk about 50 years ago. It took the teacher a decade to get anyone from southern Alberta to come to take a look.

“At the time, sort of in the ’70s and ’80s, paleontology in northern Alberta was virtually unknown,” said Bamforth.

When paleontogists eventually got to the site, Bamforth said, they learned “it’s actually one of the densest dinosaur bonebeds in North America.”

“It contains about 100 to 300 bones per square metre,” she said.

Paleontologists have been at the site sporadically ever since, combing through bones belonging to turtles, dinosaurs and lizards. Sixteen years ago, they discovered a large skull of an approximately 30-year-old Pachyrhinosaurus, which is now at the museum.

About a year ago, they found the second adult: Big Sam.

Bamforth said both dinosaurs are believed to have been the elders in the herd.

“Their distinguishing feature is that, instead of having a horn on their nose like a triceratops, they had this big, bony bump called a boss. And they have big, bony bumps over their eyes as well,” she said.

“It makes them look a little strange. It’s the one dinosaur that if you find it, it’s the only possible thing it can be.”

The genders of the two adults are unknown.

Bamforth said the extraction was difficult because Big Sam was intertwined in a cluster of about 300 other bones.

The skull was found upside down, “as if the animal was lying on its back,” but was well preserved, she said.

She said the excavation process involved putting plaster on the skull and wooden planks around if for stability. From there, it was lifted out — very carefully — with a crane, and was to be shipped on a trolley to the museum for study.

“I have extracted skulls in the past. This is probably the biggest one I’ve ever done though,” said Bamforth.

“It’s pretty exciting.”

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
