Cases of Pets Contracting severe acute respiratory syndrome coronavirus 2 (SARS-cov-2) were registered since the beginning of the spread of coronavirus (COVID-19). Now the cat was the first animal in Britain to test positive after Contracting the virus from their owners.
The cat developed symptoms of shortness of breath. Dog owners took it to a veterinary clinic where it was initially suspected feline herpes virus, common respiratory infection in cats.
A sample from the cat tested positive for SARS-cov-2 in the framework of the research program at the University of Glasgow centre for virus research. This program aims to screen hundreds of samples for the presence of SARS-coronavirus-2 in the cat population of the country. The test was conducted in the Agency and health of plant and animal life in Weybridge, Surrey, on July 22.

Experts in health say that it is the first known human to cat transmission of SARS-cov-2 in the country, but that does not mean that the infection has not spread to people for their Pets.
Zoonoses is described as viral infections that jump from animals to humans, as coronavirusesthat generally occur in wild animals such as bats, camels and civets cats, among others. Severe acute respiratory syndrome (SARS) and middle East respiratory syndrome (MERS-Cov), which come from civet cats and camels. The current pandemic coronavirus was claimed to come from dinosaurs that have been infected by bats.

On the other hand, reverse zoonosis, when the virus first infects people, and then turns to animals. Since the emergence of the novel pandemic coronavirus, reports of infections in Dogs in Hong Kong and even at a tiger in a zoo in the United States.

Spread from humans to animals
The American centers for control and prevention (CDC) says that is still unknown, whence came the present disease coronavirus, but said it may come from an animal, like a bat.
“At this time, there is no evidence that animals play a significant role in the spread of the virus, which causes COVID-19. Based on the limited information currently available, the risk of spreading animal COVID-19 people is considered low,” the CDC said.
The health Agency added that more research is needed to shed light on how different animals can be affected COVID-19. As scientists try to learn more about the virus, it seems that it can be transmitted from people to animals in some situations.
“We are still learning about this virus, but it seems that it can be transmitted from people to animals in some situations, especially after close contact with a person sick with COVID-19,” the CDC explained.
The CDC also explained that cats, dogs and other animals can be infected with the novel coronavirus. However, he says that the experts don’t know all the animals that can be infected.
Animals and COVID-19
Three previous studies have discussed the risk of animal infection with SARS-coronavirus-2. In the study, researchers in the United Kingdom by the coronavirus can infect a broad range of animal speciesincluding dogs, cats, hamsters, rabbits, horses, goats, pigs, Buffalo, sheep, cattle, and lizards. These animals showed higher levels of viral entry.
The formation of syncytia following SARS-cov-2 spike expression. Effector cells expressing half of a dual luciferase-GFP reporter protein and SARS-cov-spike 2 were mixed with target cells expressing ACE2 proteins of the indicated nodes and the corresponding half of the reporter (see methods). Also the vector only control is enabled (pDISPLAY). Representative photomicrographs protein of GFP-positive syncytia formed as shown joint cultivation are. Images were captured using Incucyte live cell imager (Sartorius).
Meanwhile, animals such as Turkey, chicken, and all kinds of bats supported lower levels of viral entry than the human angiotensin converting enzyme 2 (ACE2).the
Another study downloaded in BioRxiv identified SARS-cov-2 target cells in different tissues, a cat, a hamster, and pangolin. The most remarkable discovery was the fact that SARS-coronavirus-2 target cells was a high proportion of SARS-cov-2 target cells in cats.
Finally, scientists from the Chinese Academy of agricultural Sciences, the Chinese center for control and disease prevention, says SARS-cov-2 was capable of to engage and ACE2 receptors in a wide range of animal speciessuch as the greater horseshoe bat, domestic cat, dog, pig, goat, and Malayan pangolin.
Susceptibility to SARS-cov-2 from HEK293T cells provided by the different 2 species ACE2 I. HEK293T cells were transfected the plasmids expressing 3 ACE2 and pointed. Cells were infected with 0.5 MVD SARS-cov-2 24 h after transfection, 4, and was discovered for the replication of SARS-cov-2 ELISA.
Understanding zoonosis and reverse zoonosis of the pandemic coronavirus could help scientists study the behavior of the virus, and the likelihood of transmission from animals which can make containing the virus more difficult.
The impact of the pandemic coronavirus has already exceeded 16.48 million, resulting in the deaths of more than 654,000.
