Can Animals Have Allergies? Are They the Same as Human Allergies?

Many of Us Suffer from Excessive Immune Response to Dust, Stamens and Other Factors. What About Other Creatures?

animals and people with allergies

The immune systems of all mammals, including humans, have many common characteristics. For example, mice, cats and horses have a spleen, a lymphatic system, and white blood cells just like us. 

As we share with the rest of the mammals the benefits of an acquired immune system, which constantly learns to identify new threats, we may also share its shortcomings, such as allergies.

People can develop an allergic reaction to drugs, pollen of flowers and even innocent foods like peanuts and milk. 

And for reasons that are not completely clear, the body treats these substances, called allergens, as a hostile agent and mobilizes the immune system against them. 

Allergy can be manifested in respiratory, health, and skin problems such as shortness of breath, runny nose, and rash, depending on the substance and type of sensitivity of each person.

There have been no studies investigating wildlife allergies, but studies of domestic animals are abundant. 

In Sweden, for example, one in every 500 dogs at least develops atopic dermatitis, a disease with an allergic background that results from itching and chronic redness. 

Similarly, it is known that dogs, cats and even horses can suffer from asthma, allergic rhinitis and food allergies. 

Treatment of animals with an allergy is also similar to that of humans and relies on drugs that modulate the immune response, such as antihistamines and steroids.

Old friends, new enemies

Why do we develop allergies? In 1989, a physician named David Strachan suggested that the rise in the rate of skin diseases in the modern world is due to a decrease in exposure to infectious agents, which impairs the ability of the body to develop the ability to cope with them. His idea was called the hygiene hypothesis. 

In 2003 an updated hypothesis was suggested that the roots of this phenomenon lie in the relationship between the immune system and organisms that reside within the body.

The "old friends hypothesis"

According to this hypothesis, before the age of modern medicine, many parasitic organisms, including intestinal worms, bacteria and viruses, have been present in our bodies for the rest of our lives. 

Today, medicine knows how to destroy them, and in the absence of them there may be an imbalance in the immune system that results in overreaction, the secretion of inflammatory substances. 

Since these relationships evolved over hundreds of thousands of years, this theory was called The "old friends hypothesis".

Over the years, The "old friends hypothesis" has gained reinforcement, even when it comes to domestic animals. 

Recent research has shown that in dogs that grow in an urban environment and are not exposed to other animals, the incidence of allergic diseases is higher. 

Even in dogs who spend hours indoors, they find more allergic symptoms. It was also found that in dogs exposed to other animals and outside conditions, the population of bacteria on the skin was richer.

Studies have shown that people also live in an urban environment are at a risk for allergic diseases. An example is atopic dermatitis, which is less common in people living outside the city.

DNA can affect allergies?

Although allergic diseases have a clear genetic component (terriers, for example, develop more allergic symptoms than other dogs), it can be said that the interactions between bacteria and other parasites with the body have a decisive effect on the formation of allergies. 

The immune systems of many animals are similar to ours and therefore have the potential to react too strongly, so that dogs, cats and horses sometimes have allergic diseases. It seems that as with us, other animals also have a link between these diseases and the environmental conditions that shaped their immune systems and modern living conditions.

Researchers Identified a Virus that Attacks Cancer Cells

Researchers identified a virus that attacks human cancer cells can distinguishes Healthy cells.
Audio Version Of This Post
Viruses are usually supposed to worry us, but this is not the case with inoculate viruses. those that infect cancer cells and kill them, ignoring healthy cells. So it is no wonder that the search for such viruses attracts many researchers.

The Seneca Valley virus.This virus also known as Senecavirus affects pigs and cows. In recent years it has been found that the virus attacks human cancer cells.

The ability to identify tumors and ignore normal cells tested in two trials. The first in relapsed solid tumors in children and the second in lung carcinoma.

Experiments also found that the immune system was removing the virus from the body. Thus preventing it from completing its anticancer action.
Ongoing research to understand how the Seneca Valley virus may be used for cancer treatments.Researchers at the University of Otago in New Zealand discovered in 2017. That the vi…

New study suggests, people with better sense of smell have a better sense of direction

People with a good sense of smell also have a better sense of direction, suggesting a link between the two systems, a new study suggestsWhy do we have a sense of smell?
The smell of fruit directs us (or at least the lemurs) to the most mature fruit, and even our interpersonal relationships are affected by scents. But some researchers believe that its first use by the first animals, the advantage it gave them over the lack of sense of smell, is navigation. 

Now researchers from Canada have shown that people with a better understanding of smell also navigate better.

The olfactory bulb, the region of the brain that receives information about odors from the nose and makes the initial processing of the smell, exists in many species of animals. It has identified in mammals, birds, reptiles, and fish, and there is a similar structure, even in crabs and insects. 

For some, the bulb is tiny compared to the size of the brain, and for others, it is enormous. A study published several years ago showe…

10 Incredible Scientific Breakthroughs and New Inventions

Scientific discoveries continue to appear every year. new discoveries in a variety of fields, from innovative solutions and treatments for common and deadly diseases to archaeological discoveries, space discoveries, and unusual scandals, learn about 10 groundbreaking scientific discoveries that have taken place and can certainly affect our lives in the near future.

1. Sickle cell anemia can be cured by transplantation of stem cellsSickle cell anemia is a severe and common blood disease in which more than 4 million people worldwide are infected.

In April, a pair of scientists at the National Human Genome Research Institute announced that they had completely cured a 26-year-old man with sickle cell anemia, Through the transplantation of healthy stem cells in the body, they hope and believe that similar results will also occur in the future as more patients receive similar treatment with stem cells.
