SINCE Guilt, chickens and rats could be the key to dealing with COVID-19, according to a new study.
It turns out that they are immunized against the coronavirus because of the shape of their cells, scientists say. A Stanford University study explains why some animals, including cats and cattle, are susceptible to infection and others are not, according to Study Finds.

The discovery could lead to a drug that would hide the “key” to trap the insect and prevent it from interacting with cells.
Covid-19: Many newly infected and died in the last 24 hours.
The pandemic is believed to have started when the SARS-CoV-2 virus, which causes COVID-19, jumped from bats or pangolins to humans.
Scientists have studied how a spike in viral protein attaches itself to cells. SARS-CoV-2 enters them by binding to a specific gene known as angiotensin converting enzyme 2 or ACE2. These receptor genes are found on the surface of our cells.

Computer simulations showed for the first time how it binds to multiple ACE2 receivers, similar to inserting a key into a lock. They demonstrated the “locks” of some animals that fit better, including humans. This makes these species more susceptible to infection.
3D models also identify certain unique structural features of these species. Other creatures are immunized because their ACE2 receptors are missing, leading to less communication.
COVID-19: Crucial Indicator of Possible Serious Leak Found
Dr. Joao Rodríguez, lead author of the study, says this opens the door to drug development. You can also help prevent future outbreaks by monitoring animal hosts from which the virus can potentially infect humans.
The coronavirus is not unknown to animals. COVID-19 has been reported in cats in the United States and Belgium, minks on Dutch farms, and even lions and tigers at the Bronx Zoo in New York City.
Specialist: Do not take immunostimulants, they are harmful
“In all these cases, the ‘vehicle’ appears to be an infected human host. More importantly, in the case of mink farms in the Netherlands, there is evidence of human-to-animal and human-to-human transmission,” they write. the authors.
Studies show that camels, horses, sheep, and rabbits can also be infected, but not chickens, ducks, pigs, mice, and rats.
The coronavirus has already killed around 1.5 million people worldwide and has so far infected about 65 million. Conservationists fear that the world is on the brink of a new pandemic, as habitat destruction is bringing people closer to closer contact with wildlife populations.
The other epidemic spreading in France
The study is the first of its kind to include a detailed analysis of 29 species of vertebrates ranging from humans, chimpanzees and dogs to goldfish, crocodiles and hedgehogs. Dr. Rodríguez says the models shed new light on why some species do not contract the virus.
To reduce the risk of infecting domestic and wild animals, including endangered species, he recommended following the guidelines of the World Organization for Animal Health.
