Science supports "cat sucking"?

Small animals not only look cute, but also help to reduce people's tension and anxiety, and even relieve high blood pressure (only effective for shoveling officials)
.

Therefore, more and more people who love dogs and suck cats join the team of "shoveling shit" and enjoy it every day
.

Now, there is a new study that may make the life of shovel officials "icing on the cake
.
"
Recently, in a new study published in "eLife", a research team led by the University of California, San Diego found through mouse experiments that a unique bacterial strain isolated from cat skin has antibodies that make the skin heal.
It can fight difficult-to-treat animal and human skin infections
.

As we all know, hundreds of bacteria are colonized on our skin.
They play an important role in skin health, immunity and anti-infection
.

Both humans and animals need to maintain a diverse balance of healthy skin bacteria to combat potential pathogens
.

Methicillin-resistant Staphylococcus pseudointermediate (MRSP) is an important emerging zoonotic pathogen that can cause serious skin infections, such as severe atopic dermatitis (commonly known as eczema)
.

MRSP Since the advent of penicillin in the 1940s, Staphylococcus aureus has been basically controlled
.

But with the widespread use of penicillin, penicillin-resistant bacteria Staphylococcus aureus appeared
.

For this reason, scientists have developed a semi-synthetic penicillin, namely methicillin
.

It has effectively controlled Staphylococcus aureus infections since it was applied to the clinic in 1959
.

But then, British scientists discovered for the first time a more alarming methicillin-resistant Staphylococcus (MRSA)
.

MRSA is resistant to common antibiotics and is difficult to treat in clinical and veterinary settings
.

Since the discovery of MRSA, infections have spread almost all over the world, and it has become one of the important pathogens in hospitals and communities.
In order to combat the infection of drug-resistant bacteria, scientists usually use bacterial therapy, that is, by transplanting bacteria that are known to be beneficial to health.
Bacteria) to help resist the proliferation of harmful bacteria to create a symbiotic and balanced environment
.

In this study, the researchers first screened some bacteria that usually live in dogs and cats, and cultivated them in the presence of MRSP
.

Subsequently, the researchers isolated a feline bacterium called Staphylococcus felis, which can inhibit the growth of MRSP and a variety of Gram-positive pathogens, by destroying the cell wall of MRSP and increasing the production of toxic free radicals.
Come to kill MRSP
.

Generally, bacteria are easily resistant to a single antibiotic, and S.
felis has four genes encoding four different antibacterial peptides, that is to say, this special bacteria will naturally produce a variety of antibacterial agents, each of them Can kill MRSP alone, once combined, MRSP is not an opponent at all
.

Subsequently, the researchers tested Staphylococcus felis in mouse experiments
.

They exposed the mice to the most common pathogens and then added S.
felis bacteria or bacterial extracts to the same site
.

The researchers found that compared with animals without treatment, mice treated with S.
felis bacteria and bacterial extracts significantly reduced the colonization of MRSP on the skin, and the skin scales and redness were reduced; S.
felis extracts were significantly reduced Reduce skin necrosis damage caused by MRSP infection
.

The team stated that the next step will be to conduct a clinical trial to determine whether S.
felis can be used to treat MRSP infection in dogs
.

This discovery can be said to be the gospel of shit shovel officers
.

But the researchers reminded not to keep these "super antibacterial agents" on the "master" without bathing them
.

The skin has evolved the ability to protect beneficial bacteria, pet bath lotion and soap usually do not wash away the beneficial bacteria
.

Richard Gallo, the corresponding author of the study and a distinguished professor and chair of the Department of Dermatology at the University of California San Diego School of Medicine, said: "Those who keep cats may get some protection against methicillin-resistant Staphylococcus pseudointermediate
.

So, our study may also It is an argument in favor of keeping pets
