How cats and cows protect farm children from asthma

Date:  July 6, 2017

Summary:  It is a known fact that microbes on farms protect children from asthma and allergies. But even non-microbial molecules can have a protective effect. Immunologists have shown that a sialic acid found in farm animals is effective against inflammation of lung tissue. This study opens up a wide variety of perspectives for the prevention of allergies.

Meet Nano, the nut-detecting, allergy-busting wonder-dog

A dog named Nano has become the first in Europe to be trained to sniff out nuts and snuff out allergies.

The four-year-old poodle can pick up nut odours in both food and the environment, following his training by a medical dog charity in Milton Keynes, Buckinghamshire.

The pup has been paired with severe nut allergy sufferer Yasmine Tornblad, 30, and his nose for nuts has dramatically transformed her life.

Ms Tornblad, from Malvern, Worcestershire, can go into anaphylactic shock from just the smell of nuts and has been rushed to hospital 15 times within the last eight years.

The IT worker now takes Nano everywhere she goes including the office, business trips and even flights saying.

‘It has given me a bit of independence back. I can’t imagine life without him,’ she said.

The Medical Detection Dogs charity has also taught dogs to sniff out cancer and help people manage conditions such as diabetes.

Oral Drops for Dog Allergies Pass Another Hurdle

ScienceDaily (July 24, 2012) — A study reported July 24 at the World Congress of Veterinary Dermatology in Vancouver, British Columbia, shows that placing allergy drops under a dog's tongue can be as effective as allergy injections for controlling skin allergies.

In dogs, allergies to house dust, pollen, and mold cause atopic dermatitis, an itchy skin inflammation. Dogs, like people, can be desensitized through "immunotherapy" using shots or drops that deliver small doses of the allergen to "train" the immune system to tolerate foreign proteins.

Both technologies are now about a century old, but for humans and animals, allergy shots are more commonly used.

Chief author of the new study, Douglas DeBoer, a professor of dermatology at the University of Wisconsin-Madison School of Veterinary Medicine, sees several benefits emerging from the new study, which treated skin allergies in 217 dogs using allergy drops.

Why Having a Dog Helps Keep Kids Asthma-Free


If you're a dog person, your kids might be in luck. Research suggests that children who grow up in homes with pets are less likely to develop allergies, and now a recent study by researchers from the University of California, San Francisco, sheds some light on why.
Working with mice, the scientists found that exposure to housedust from homes with a pet appeared to protect the mice against a common virus called respiratory syncytial virus (RSV), which infects the lungs and breathing passages and is a major cause of respiratory illness in young children. (In adults, it usually causes run-of-the-mill cold symptoms.) Severe infections in infancy are linked with an increased risk of developing respiratory problems like asthma later on.
Lead researcher Kei Fujimura and her team looked at three groups of mice. One group was fed house dust from homes with dogs, and then exposed to RSV; a second group was infected with RSV without exposure to dust; and a control group of mice was not exposed to RSV or dust.
The study found that the mice that ingested house dust and were exposed to RSV didn't develop the telltale symptoms of infection, such as lung inflammation and mucus production -- these animals looked just like the controls. The researchers then examined the microbes living in the protected animals' guts, and found that the types of bacteria they harbored were different and more diverse than the bugs in the RSV-infected animals guts.
What do gut bugs have to do with asthma? Potentially a lot. Researchers are discovering that the microbiome, as it's known -- the vast community of good bacteria and viruses that live in and on the human body, including in the intestines -- not only play a vital role in basic bodily functions like digesting food, producing vitamins and fending off infection, but may also contribute to the development of chronic conditions and diseases like obesity, cancer and asthma.

Lack of contact with nature 'increasing allergies'


A lack of exposure to a "natural environment" could be resulting in more urban dwellers developing allergies and asthma, research has suggested.
Finnish scientists say certain bacteria, shown to be beneficial for human health, are found in greater abundance in non-urban surroundings.
The microbiota play an important role in the development and maintenance of the immune system, they add.
"There are microbes everywhere, including in the built environment, but the composition is different between natural environments and human-built areas," explained co-author Ilkka Hanski from the University of Helsinki.
"The microbiota in natural environments is more beneficial for us," he told BBC News.

Gluten Sensitivity in Sport Horses



ScienceDaily (Apr. 30, 2012) — Chronic inflammatory small bowel disease has an increased prevalence in sport horses. The disorder is associated with intermittent colic, weight loss, poor performance and anemia. Chronic inflammatory small bowel disease seems to have a predominance in dressage horses, but its exact cause is unknown to date.

Researchers of the Free University of Amsterdam and Utrecht University in the Netherlands have now identified gluten sensitivity as a potential cause of equine chronic inflammatory small bowel disease in sport horses.

Gluten is a major compound of the endosperm of various cereals, in particular of wheat, barley and rye. Especially the gliadin fraction of the gluten is associated with Coeliac disease (gluten intolerance) in man.

Some horses fed a gluten-rich ration showed concurrent antibody responses as seen in celiac patients. To test the pathogenic role of gluten, one sport horse with chronic inflammatory bowel disease and antibodies followed a gluten-free ration during 6 months. Both villous morphology and blood antibody titers improved in this horse.

The development of a screening test aimed at identifying gluten-sensitivity in individual horses based on blood samples is currently in progress.

Allergies in pets: Airborne, fleas, food, contact

LOS ANGELES (AP) — Allergies can cause misery for pets and humans alike. But allergies in animals are not always easy to diagnose and treat.
"I feel so bad because he can't tell me what's wrong," said Angela Duyao of Gilroy, 80 miles south of San Francisco. Harley, her 2-year-old Shih Tzu, has food and seasonal allergies.
It took Duyao, an administrative assistant, 18 months and over $1,000 to find out Harley was allergic to poultry and pollen.
All dogs and cats can get allergies, and the most common reaction is scratching, said veterinarian Donna Spector, an internal medicine specialist based in Deerfield, Ill.
"Allergies are a real head-banger. They are frustrating for vets, they're frustrating for clients and the dogs and cats itch like crazy so we know it is frustrating for them. Allergies are very challenging to diagnose accurately because it's a diagnosis of exclusion. It takes a lot of money and a lot of time. It takes a very dedicated owner," she said.
There are four kinds of pet allergies: airborne (tree, grass and weed pollen; mold, mildew and dust mites), fleas, food and contact (like carpeting or detergent). The most common pet allergy comes from fleas.
People and pets can cause each other problems: People can be allergic to pet hair or dander and pets can be allergic to products humans use.
Most pet allergies cause scratching. Some other symptoms include discoloration of hair between toes, rashes, open sores, watery eyes, ear infections, runny noses, vomiting and diarrhea, said Spector, a frequent guest on "The Ellen DeGeneres Show." She is a consultant to the pet food company co-owned by DeGeneres called Halo, Purely For Pets.
Spunky, an 8-year-old husky mix owned by pet sitter and photographer Ashley Niels, didn't have problems until his family moved to Austin, Texas.
In Texas, he licked himself raw, forming a hot spot on his back, Niels said. The vet put Spunky on antibiotics and gave him a steroid shot. "We didn't have the money to do allergy testing, so we tried diet trials," she said.
But it wasn't food. It was cedar dust and grasses.
"The poor dog lived in a cone for six months," Niels said.
Between the cone, a daily dose of anti-itch medicine and spray salmon in his food, Spunky's allergies became manageable. (Salmon can relieve itching and skin conditions in animals.) He is now off the cone, medicine and steroids.
Niels worries Spunky's allergies will flare up in the coming weeks, but she is ready with the cone if he needs it.
Among the three dogs, six cats, four rats and two ferrets in the Niels household, there is an 8-year-old cat named Zane who used to throw up every day. Through trial and error, Niels found out he was allergic to poultry. Zane's diet doesn't have much variety these days, but he's stopped vomiting, Niels said.
Most pet owners will try to help their pets with allergies, Spector said. "The signs are so annoying and so significant, it rarely goes untreated. The scratching drives owners crazy."
Beyond money, it takes time. If a pet is hurting, the owner wants a quick fix and it can take months, going on years, to find the answer.
Flea allergies pose unique problems. "One flea can jump on a dog, bite it and keep it symptomatic for seven days," Spector said.
Carol Meir of Takoma Park, Md., spent 18 months experimenting with diet to cure digestive problems in her 4-year-old hairless cat Moshe Moshi.
Meir changed flavors and brands of cat food, cooked for him and took him to animal nutritionists. The conclusion: Moshe Moshi was allergic to poultry and wheat.
"It was easy to eliminate wheat from his diet, but it's really hard to eliminate poultry. You'd be surprised how many products have egg as an emulsifier," she said.
Meir is managing the cream point sphynx's allergies with a venison and pork diet and daily medication. She figures it cost her about $750 for vets and tests. Medicine is $250 a year.
"He is worth it. He is the sweetest cat," she said.
Meir was recently diagnosed with a dust mite allergy herself and all three of her cats will benefit, she said.
She's replacing everything from beds (hers and theirs) to carpets and having all air ducts cleaned.
Duyao has always tried to do right by Harley too. He's got his own stroller and spends three days a week at doggie day care. She spent what it took to identify his allergies.
But a medicine mistake cost her $1,000 and nearly cost Harley his life.
Harley was taking over-the-counter children's allergy medicine on the recommendation of a vet. Duyao ran out one day so she cut up an adult pill.
"He reacted to something in it. It was very scary. He was jittery, his head was bobbing back and forth, his eyes were watery, he was salivating bad, his little heart was beating so fast," she said.
She got him to the vet where they put him on a charcoal IV to drain the poison.
When she picked him up from the vet's the next day, he was fine. "But it was a good lesson," she said.

Jack Russell who is allergic to grass has special 'doggy boots' made

This Jack Russell has to be dressed in specially made boots for walkies to protect his delicate paws because he is allergic – to grass.




Eight-year-old Jaxs suffers a painful reaction if he comes into contact with even a single blade of grass. It causes huge clumps of fur to fall out and leaves Jaxs with huge sores on his sensitive paws.

But Jaxs' life was transformed after a local vet suggested his owner Maria Domanic fit him out in 'doggy boots'.


Retired care worker Maria, 59, from Kingsbridge, said: ''He absolutely loves the boots. Initially he was a little tentative but now he's become very protective of them.

''I never really put two and two together with the allergy.

''One day, I took him to the vets and had him tested, which showed he was allergic to grass, as well as milk, protein and oats.

''He's so happy to finally be able to run around the field with other dogs.

''The allergy proves very painful for him and he would sometimes gnaw at his paws after walks."

Little Jaxs has become so attached to the boots, which are made of canvas and attached using velcro, that he even picks them up in his mouth before walkies.

Maria said: ''As soon as I get the lead he runs off and gets his boots and if another dog comes round or anyone tries to pick them up he will run off and protect them. He even sleeps with them in his basket."

"I've had a few people make some odd comments branding me 'cruel' and 'disgusting' for dressing him up in clothes," she said. ''I have to explain it's for his own good."
