In the pigsty in the backyard, Gao Fushan stood next to a litter of patterned piglets with a sampling box, his face with a mask could not see his expression clearly, but his exposed eyes flashed with pity.

Seeing the mentor Nan Zhiqiao coming over, Xiao Gao hurriedly greeted and said, "Teacher Nan, look at these little piglets, something is wrong." ”

Nan Zhiqiao approached the pigs and found that more than a dozen little piglets with patterns had symptoms of runny nose, flushed conjunctiva, tears, and rapid breathing, and some of the piglets were swimming on all fours and lying on the ground.

Look at the lactating big white pig next to him, crooked to the side, drowsy, with a lump on the skin under the neck.

Nan Zhiqiao wore gloves and gently pressed the lump, which was swollen lymph nodes.

The ears and limbs of the big white pig were plucked, and the skin on the tips of the ears, the lower ends of the limbs, and the abdomen was widely congested and flushed.

Several other pigs were examined, and two of them had symptoms similar to those of the Great White Sow.

Nan Zhiqiao stood up and said: "These pigs already have the initial symptoms of Streptococcus suis infection, first use antibacterial drugs sensitive to Streptococcus suis for isolation treatment, see the treatment effect, and then decide how to deal with it, during this period, we should pay attention to the disinfection of the pigsty, and within fifty days, do not buy and sell live pigs." ”

Shi Jianjun endured the pain all over his body and said, "There is a veterinarian in the village, go to him to get medicine now." ”

The woman helped Shi Jianjun and complained: "You are like this, how can you go to get medicine, I will go to the hospital in a while, I will also follow, no one at home can't do it, let the uncle come over to help see for a few days." ”

"That's all there is to it. Shi Jianjun agreed with his woman's suggestion.

Uncle Cai quickly drove someone to pick up Shi Jianjun to the hospital, before getting into the car, the woman of Shi Jianjun's family was still muttering, "It's all infected by Shi Guohua's wild boars, or we have raised pigs for so many years, and no pigs have transmitted the disease to people, they are all caused by wild boars, and I wouldn't have gone to his pig farm to find wild boars to breed ......

The woman muttered and complained, Shi Jianjun couldn't listen to it, and scolded: "Don't say it, the experts didn't say anything, and I don't know if it's a wild boar." ”

Uncle Cai took someone to help Shi Jianjun into the car, and after a few words, the driver drove to the direction of the hospital.

Seeing off Shi Jianjun, it was already twelve o'clock at noon.

The six members of the expert group gathered together, had a brief lunch, exchanged the results of the morning investigation, and arranged the work for the afternoon.

Nan Zhiqiao was very interested in Shi Guohua's pig farm on the mountain, and always felt that there would be clues about the outbreak of the human-Streptococcus suis epidemic in it, so when he saw Uncle Cai in the afternoon, he asked Uncle Cai to take three people to the pig farm on the mountain to have a look.

Uncle Cai agreed very happily, and on the way up the mountain, he also introduced the situation of the pig farm to Nan Zhiqiao and his party.

The pig farm on the mountain was built by Shi Guohua two years ago, and the pig farm is very simple, that is, on the flat hillside, local materials are taken, and the wall of the pigsty is built with mountain stones, and the trunk, thatch, and tarpaulin are built into the top of the pigsty.

The farm is divided into a dozen small pigsty with a few large white sows, but more black wild boars.

These black wild boars were all caught alive by Shi Guohua in digging traps in the old forests of Jingshan, and the sturdy male wild boars were left to breed with domestic pigs.

The hybrid generation has the characteristics of wild boars, as well as the docile character of domestic pigs, which is easy to raise, and the meat quality is as delicious as wild boars, which is very popular with people, so the price is much more expensive than ordinary domestic pigs.

Shi Guohua's pig farm made a lot of money because of breeding and raising hybrid wild boars, and the local villagers saw that raising wild boars could make more money, and they also followed Shi Guohua's practice, but the problem is that the villagers did not have Shi Guohua's technology of going into the mountains to catch live wild boars, and finally thought of a compromise and drove their sows to Shi Guohua's mid-mountain pig farm for breeding.

Once you successfully breed with a wild boar, you will give Shi Guohua money once, so that the villagers have both wild boars and Shi Guohua can also make extra profits.

The pig farm on Shi Guohua Mountain is getting bigger and bigger, and there is not enough manpower, so he invited an old man who lived at home to go up the mountain to help raise pigs.

Shi Guohua built two small bungalows next to the pig farm, one for the old man to live in, and the other to store miscellaneous belongings.

With the help of the old man, Shi Guohua's family moved back to the village from the mountain, and the old man has been living on the mountain to take care of the pig farm, and Shi Guohua will go up the mountain every two days to deliver pig feed or other supplies.

The rest of the village, except when the pigs are breeding, does not go to the mountains at any other time.

Along the way, Uncle Cai gave a general overview of the situation of the pig farm on the mountain.

The rugged mountain road, the higher you go, the steeper the surrounding mountains, the thicker the surrounding trees, just when everyone thought that they had entered the deep mountains and old forests, and there was no way out, they turned a bare rock, and a wide and gentle slope appeared in the woods.

There are stone houses on the hillside, and a pigsty made of branches, tarpaulin, and thatch.

The pig farm appeared in front of everyone's eyes.

Uncle Cai began to shout far away from the pigsty, "Hey, old ginger, I've brought someone." ”

After a while, no one responded.

Uncle Cai continued to walk forward, shouting as he walked: "Hey, old Jiang Tou, are you there, make a sound." ”

Still no one responded.

The closer you get to the pigsty, the more eerie the quiet atmosphere becomes.

According to the normal situation, there is more or less the sound of pigs humming and foraging near the pigsty, but now, there is no sound, and no one comes out.

The smell of dung wafted in the air, mixed with the smell of dung, and the smell of rotting animal carcasses.

Ye Zhenzhen covered her nose and walked beside Nan Zhiqiao, and Xiao Gao followed behind with a sampling box.

Uncle Cai, who had gray hair, walked in the front, the first to approach the pigsty, and when he stood at the root of the half-man-high wall of the pigsty, Uncle Cai looked up at the situation in the pigsty.

"Oh my God!" exclaimed Uncle Cai.

Hearing Uncle Cai's cry, Nan Zhiqiao and the three of them walked a few steps closely, and soon arrived at the edge of the pigsty.

Seeing the situation in the pigsty, everyone was shocked, Gao Fushan covered his nose and retched a few times before exclaiming: "Why are the pigs dead?"

In the pigsty, a large white sow and a group of small pigs lay on the ground, the carcasses of the pigs had begun to decompose, and the stench of decay attracted a large number of flies.

The carcass of the sow was rotting and distended, the belly was bursting with the gas produced by the decay, the intestines and rotting internal organs were running to the ground, and white maggots were burrowing at the surface, making the human scalp tingle.

Uncle Cai hurriedly ran to other pigstys nearby to check, and the more he looked, the more disgusting he became, and the situation in other pigpens was the same.

The pigs on the farm are all dead!

Nan Zhiqiao wore masks and gloves, took the sampling box from Xiao Gao's hand, opened the door of the pigsty, walked to the pig carcass, and began to check.

It is now a hot summer, and the pig carcass is exposed to the sun and is badly decomposed, and it is difficult to examine the cause of death from the surface of the carcass.

Nan Zhiqiao opened the sampling box and used a sterile cotton swab to collect specimens from different parts of the pig carcass, and as soon as he put the specimens back into the sampling box, he heard a scream from the bungalow not far from the pigsty.

"Ah...... Monster!"
