Chapter 1460 - Route of transmission

“No.” Famous was convinced.

“What’s going on with the coyote? Why is there such a beast in San Francisco?” He asked, and went back with Zhang Zian towards the house.

“Wait a minute.”

Zhang Zian noticed that there was a wet stain on the pavement and stopped Famous because Famous might just step on this wet stain with two more steps.

“Is this…water? Or is it sweat?” He bent over and looked closely, but couldn’t tell. Maybe it was Zhou Jing’s sweat, maybe it was dripping water from a passing car, or maybe it was the saliva sprayed by the Pomeranian’s barking…all options are possible.

Famous didn’t understand what a small wet stain can be fussed about by him, but Zhang Zian’s expression was serious, so it didn’t dare to take it lightly.

“It’s not water or sweat. It seems like…the coyote’s urine.” Its nose has been able to distinguish the nature of the wet stain on this road.

Zhang Zian sighed for a moment and drew an arc over it, “Come around, don’t step on it.”

“You want to protect the scene?” Famous wondered. It could only think of such an explanation.

“No.” Zhang Zian shook his head. “Some diseases, such as Mad Cow disease, can be transmitted through urine. That is, even stepping barefooted on infected lawns with infected cattle’s shit and pee may also cause one to be infected.”

“What?”

Famous was taken aback, even thinking that he had heard it wrongly, “You can even get infected by walking barefoot on the lawn covered with urine?”

“In theory, of course, though the probability of infection is very low. However, there is no need to take this risk, right?” He looked around, picked up a tree branch, and dug some soil to cover the urine.

Although it sounds incredible, it is the case. What caused the BSE to spread is a special type of virus…It is not accurate to say that it is a virus. It is more of a special protein that humans know very little, and urine may contain this special protein.

He didn’t want to be a sad story, but he was careful so that he can continue living for a good many years. If he was infected because he stepped on the urine, it would be an unjust death.

Humans wear shoes well. Even if they have stepped on the mad cow’s urine, it is not a problem, but Famous is barefoot, and the other elves are also barefoot.

Famous bypassed the urine covered by the beach, and he turned back and looked back frequently.

A man and a dog walked back from the stairs to the bedroom on the second floor, and the other elves gathered curiously beside the balcony door to witness what had happened earlier. Thus, they had all heard Zhang Zian’s words.

Zhang Zian first entered Zhou Jing’s number into his mobile phone and then relayed the conversation he had with Father Yang on the plane to the elves. Richard also made some extra additions about Ghent University.

What he didn’t expect was that upon hearing about the coyote attack on the plane, he gets to see them on his first day in San Francisco.

“Why do coyotes go crazy?” The question of Famous is also a common question between Zhang Zian and the other elves.

Since the primitive era, human beings have dominated the earth for tens of thousands of years. Needless to say, existing animals basically instinctively fear humans, or they try to live in harmony with humans like cats and dogs. How will any dare to actively attack humans?

The possibility that they have all gone crazy does not exist. The most likely explanation is that they are sick or poisoned, which leads to their unconscious behavior and aggressive nature.

The coyotes being poisoned is actually okay, for at least it is not contagious. Unless the toxin is spread by the carcasses of other animals after death, it will be more dangerous, but the scope of the spread is also likely to be very limited.

He is afraid that it is an infectious disease that has not been discovered by humans…or an infectious disease that has been discovered by humans but not known if canines will be infected by it.

Famous remembered the scene of confrontation just now and described the look of the coyote, mainly about its eyes being dim and gray, and the lack of a sense of direction.

This reminds Zhang Zian of the dog he saw in the pet clinic, and its eyes appear to be whitish and gray, which is a rare feature.

Chinese dogs, American coyotes…They are separated by the Pacific Ocean, but is there any connection between them?

Dogs and coyote are canines. Many people have misunderstood 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.

Defining a species requires that the offspring of this species that breeds within the species have stable and fertile traits and that they cannot breed with other species. Even if they did, the offspring that is born is infertile. In short, it is reproductive isolation.

From this definition, dogs, wolves, and coyotes are all the same species. They can be freely paired and reproduced, and their offsprings are fertile.

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

He tried to sort out his thoughts.

He previously suspected that the American dog food named Loshi caused strange diseases in Chinese dogs, and further caused the strange illness of the staff at the waste recycling station. However, he could not determine the root cause of the strange disease. The toxin in dog food is caused by the germs in dog food, and it is not certain whether it is able to transmit freely. If the toxin spreads between dog food, dog meat, and then to people, it is called transmission, not an infection.

But from the test report given by Wei Kang, from the routine inspection, he could not find any special harmful ingredients in that bag of dog food…

Except for one point-the meat in dog food, which is a complex source of protein, has large particles from chicken, duck, fish, and beef, common meats in the market. However, the source of finely grounded meat powder was not detected.

The meat powder is not necessarily meat or at least 99% of the time, and it is not meat. If it is meat, it is not necessary to grind it into powder. Generally, it is the powder made after the bones or animal organs are dried.

As for what kind of animal it is…he always thought it was a stray cat or a stray dog, or from the cat and dog carcasses from an animal shelter that had been euthanized because no one adopted it. However, perhaps there is something else? After all, it’s easy for such activities to be leaked. Once leaked by the animal shelter staff who cannot keep their mouths shut, it is likely that the entire operations will be shut down.

Will it be some kind of wild animal? Some kind of wild animal that can be used as both a coyote control and a dog food ingredient?
