Chapter 1460 Contagion

After Zhou Jing left, Zhang Zian suddenly remembered that he forgot to ask which aquarium she worked in, because there are several aquariums in San Francisco and surrounding areas, which one did she work in?

But it’s not urgent. It’s not too late to call her when you decide to go to the aquarium. There’s no need to ask her now. Don’t disturb her class. It’s not easy to work and study while studying, especially in San Francisco, where the rent is expensive. outrageous city.

If you are lucky, you can ask her if the aquarium she is in is still recruiting people, and even if not, you can introduce the situation of other aquariums. After all, she probably stayed in San Francisco for a long time.

Femas asked: "The animal just now is called a coyote?"

"Hmm." Zhang Zian asked, "You weren't touched by its teeth or saliva, were you?"

"No." Femus was sure of this.

"What's the matter with the coyote? Why is there such a beast in San Francisco?" It asked, and walked back to the house with Zhang Zian.

"Wait a moment."

Zhang Zian noticed a wet spot on the road, and stopped Fei Max, because after two more steps, Fei Max might just step on this wet spot.

"Is this... water? Or sweat?" He bent down and looked carefully, but he couldn't see it, maybe it was Zhou Jing's sweat, maybe it was the water dripping from a passing car, maybe it was the saliva that Bomei spewed out when he barked. ...it's all possible.

Femas didn't understand what a fuss was about a small pool of wet stains, but Zhang Zian's expression was serious, so it didn't dare to take it lightly.

"It's not water or sweat, it's like... coyote urine." Its nose had already identified the nature of the wet stain.

Zhang Zian pondered for a moment, then drew an arc towards it, "Go around, don't step on it."

"Protect the scene?" Femas wondered, it could only think of this explanation.

"No." Zhang Zian shook his head, "Some diseases, such as mad cow disease, can be transmitted through urine, that is to say, even if you just step on the lawn with the urine of a sick cow with bare feet, you may be infected."

"what?"

Femas was taken aback, and even thought he heard it wrong, "Can you get infected by stepping on the lawn with urine on your bare feet?"

"In theory, of course the chance of infection is very low, but there's no need to take the risk, right?" He searched around, picked up a branch, and

I dug some soil to cover the puddle of urine.

As incredible as it may sound, it is true. It is a special virus that causes the spread of mad cow disease... It is not accurate to say that it is a virus. The correct statement is a special protein that humans know little about, and this special protein may be contained in urine.

He didn't want his words to come true, but he had to be careful when sailing for ten thousand years. If he got infected by stepping on urine, it would be an unjust death.

It's fine for humans to wear shoes, even if they stepped on the urine of a mad cow, it's not a big problem, but Femas is barefoot, and other elves are also barefoot, so we must guard against it.

Fimas walked around the puddle of urine covered in soil, and turned his head to look back frequently with lingering fear.

One person and one dog returned to the bedroom on the second floor from the stairs, and other elves gathered curiously beside the balcony door to witness what happened just now, and heard Zhang Zian's words.

Zhang Zian first recorded Zhou Jing's number into the phone, and then relayed Father Yang's conversation on the plane to the elves. Richard also made some supplementary additions about Ghent University.

Unexpectedly, I heard about coyotes attacking people on the plane and witnessed it with my own eyes on the first day in San Francisco.

"Why did the coyote go crazy?" Femas's question was also a common question of Zhang Zian and other elves.

Since primitive times, humans have dominated the earth for tens of thousands of years. Needless to say, extinct animals, the existing terrestrial animals basically instinctively fear humans, or try to live in harmony with humans like cats and dogs. How can coyotes be unknown? Dare to take the initiative to attack humans?

The possibility of collective neurosis is non-existent, the most likely explanation is that they were sick, or poisoned, which caused them to become delirious and aggressive.

It’s okay to be poisoned, at least not contagious, unless the dead body is eaten by other animals after death and the toxin spreads, but the scope of the spread is also very limited.

I'm afraid it's some kind of infectious disease that humans haven't discovered...or some kind of infectious disease that humans have discovered, but they don't know that canines can infect them.

Fimas recalled the scene of the confrontation just now, and described the coyote's demeanor, mainly because of the dim and gray eyes and the lack of sense of direction.

This reminded Zhang Zian of the dog he saw in the pet clinic, his eyes seemed to be white and gray, this unusual feature was quite rare.

Dogs in China, coyotes in the United States... Across the Pacific Ocean, is there any connection between them?

Dogs and coyotes are both canids. Many people have misconceptions that dogs are dogs and wolves are wolves. In fact, dogs are not a separate species at all, and they are biologically equivalent to wolves.

To define a species, it is required that the offspring of this species are stable and fertile when it reproduces within the species, and the offspring that cannot reproduce with other species and give birth to offspring are infertile. In short, it is reproductive isolation.

From this definition, dogs, wolves, and coyotes are all the same species, they can freely pair and reproduce, and the offspring they give birth to are also fertile.

If an infectious disease can be transmitted to wolves, it must also be transmitted to dogs and coyotes, and vice versa.

He tried to clear his mind.

He suspected that it was the American dog food called Leshi that caused the strange disease in Chinese dogs, and then caused the staff of the waste recycling station who secretly ate dog meat to also suffer from the strange disease, but he was not sure what the source of the strange disease was The toxins in the dog food are caused by the germs in the dog food, and it is not sure whether it will be contagious - if the toxin spreads between dog food, dog meat and humans, it is called transmission, not infection.

However, according to the test report given by Weikang, from the routine inspection, no special harmful ingredients in the dog food can be found...

Except for one point - the meat in dog food, that is, the source of protein is complex, and the large particles come from conventional meat such as chicken, duck, fish and beef, while the ground meat powder has no detected source .

Meat powder is not necessarily meat, or in other words, 99% of the possibilities are not meat. If it is meat, there is no need to grind it into powder. It is usually bone or animal offal that is dried and ground into powder.

As for what kind of animal it is...he always thought it was a stray cat or a stray dog. Could it be that the corpse of a cat or dog that was euthanized because no one adopted it from an animal shelter was actually something else? After all, doing so is easy to leak, and once it is leaked by a talkative animal shelter employee, it is likely to be criticized by everyone.

Could it be some kind of wild animal—something that would serve as both coyote prey and an ingredient in dog food?
