Alert! Non-plague outbreaks have been detected in some provinces and cities, and some pig farms have been alarmed

According to the cover news report, recently held a symposium on the situation of African swine fever prevention and control in Sichuan Province, Sichuan Province, the Department of Agriculture and Rural Affairs chief animal pastor Zhao Yong out, as far as the country is concerned, the situation of African swine fever prevention and control is not optimistic, some provinces (cities) have found the African swine fever epidemic, in the outbreak prevention and control can not be taken lightly.
and deployed to carry out this winter and spring african swine fever and other major animal disease prevention and control work.
note that recent media reports said that "a new form of African swine fever virus has been identified in some pig farms in China, and industry insiders believe that the virus is caused by illegal vaccines".
reported that more than 1,000 sows affiliated with a group of companies were infected with two new strains of the African swine fever virus, according to First Financial Reported, has received a response from a group of companies.
industry experts say that if the new strain is widely spread, it will do great harm to the industry once again.
be vigilant! Some provinces and cities have found non-plague outbreaks, some pig farms surprised the mutant strain? Some provinces (cities) have found outbreaks of swine fever in Africa, Sichuan deployed this winter and spring African swine fever and other major animal disease prevention and control work according to the cover news report, recently held in Chengdu, Sichuan Province, the Department of Agriculture and Rural Agriculture and Rural Affairs Chief Livestock Division Zhao Yong attended the meeting and spoke, some experts and enterprises to participate in the meeting.
Zhao Yong pointed out that the situation of prevention and control of swine fever in Sichuan Province is more optimistic, has not yet tested positive for the outbreak of swine fever in Africa, and has not yet seen abnormal pig deaths.
But as far as the whole country is concerned, the situation of swine fever prevention and control in Africa is not optimistic, and some provinces (cities) have found outbreaks of swine fever in Africa, which should not be taken lightly in the prevention and control of the epidemic.
meeting, Zhao Yong said that the agricultural and rural sector should be deployed to carry out this winter and spring African swine fever and other major animal disease prevention and control work, to ensure that all comprehensive prevention and control measures to be implemented; Immediately test key links and key personnel; Strengthen customs inspection, into Sichuan Province, pig, pork products must all test qualified before entering the country; We will crack down on online pig purchases and illegal pig transportation.
African swine fever surprised the mutant strain, suspected of illegal use of "African swine fever vaccine" caused by the first financial report, for the "African swine fever" has not yet been vaccinated, China has always adhered to the "comprehensive biosecurity prevention and control" of the technical route, and achieved certain results.
unexpected, some illegal use of the so-called "African swine fever vaccine" may have brought new strains of mutants.
, media reports said that "in some pig farms in China identified a new form of African swine fever virus, industry insiders believe that the virus is caused by illegal vaccines."
reported that an industry expert said that more than 1,000 sows affiliated with a group of companies were infected with two new strains of the African swine fever virus, as well as some of the company's contracted farmers fattening pigs.
the virus is missing two genes, MGF360 and CD2v.
the above-mentioned content, the company's staff told first financial reporters, "It is true that individual infected pigs, have been culled."
company's attitude and confidence in non-plague prevention and control has not changed, has been firmly follow the technical route of comprehensive biosecurity prevention and control, has never used any form of non-plague vaccine, the current situation of non-plague prevention and control is also overall controllable, the impact of passive infection is also limited.
" industry experts have told the media that the source of the virus is not clear, but did find some genetically missing virus caused by mild infection.
two new strains are missing 1 or 2 genes compared to wild poisons, and although they do not have the same lethality as previously popular wild poisons, they can cause chronic symptoms and reduce the number of piglets produced.
companies and other large manufacturers have been culled to stop the spread, making the new virus substantially lethal.
although the number of known infections is relatively small, if the new strain is widespread, it will do great harm to the industry again.
newly discovered viruses that are missing both MGF360 and CD2v are strikingly similar to the African swine fever vaccine being developed in China.
September 10, 2019, the Chinese Academy of Agricultural Sciences released a message saying: China's African swine fever vaccine development in April this year after the success of laboratory research, in August this year, the vaccine research and development work has made new important progress.
a double gene-missing weak virus live vaccine has completed laboratory safety assessment and effective experiments, broke through the bottleneck of large-scale production technology, recently submitted to the Ministry of Agriculture and Rural Areas biosecurity evaluation application, is about to enter the clinical trial stage.
missing gene from this "double gene missing weak live vaccine" is the missing gene strain of MGF360-505R and the joint absence of CD2V and MGF360-505R.
6, 2019, an invention patent was published online by the State Intellectual Property Office under the name "The gene-missing detoxifying African swine fever virus and its application as a vaccine".
inventors: Step Zhigao, Chen Weiye, Zhao Dongming, He Xijun, Liu Renqiang, Liu Jinxiong.
announced that the Chinese Academy of Agricultural Sciences Harbin Veterinary Research Institute developed two African swine fever gene deletion virus, strains can provide 100% immune protection against the African swine fever epidemic in China strong strains, can be used as a safe and effective vaccine to prevent and control the outbreak of swine fever in Africa in China.
studies have shown that removing the MGF360 gene can provide immunity to pigs, but the modified virus has not been developed as a vaccine because it tends to be more toxic.
illegal use of the african swine fever vaccine, which has not been approved, has led some in the industry to fear accidental infections and spread.
industry experts have told the media that some people based on information published in the scientific literature copied the vaccine under study, the illegal vaccine of pigs may have infected other pigs.
, it's definitely man-made, it's not a natural strain, " he says.
fact, although China is on the road to developing a vaccine against swine fever in Africa, it has not yet succeeded.
on January 19th, at the 2021 working meeting of the Chinese Academy of Agricultural Sciences, Tang Huajun, president of the Chinese Academy of Agricultural Sciences, said that the african Swine Plague Weak Poison Vaccine Laboratory had successfully completed the creation, intermediate trial, biosecurity environment release trial and phase I clinical trial, biosysecry trial and phase II clinical trial, which further proved the safety and effectiveness of the vaccine, broke through the key bottleneck of large-scale production process and made a solid step towards industrialization.
but the illegal manufacture and use of the African Swine Fever Vaccine also exists.
the emergence of this invention, so that many people feel that China's "pigs are saved."
this time, "African swine fever pilot seedlings", "home seedlings", and even "smuggling seedlings" in some parts of the country farmers put into use, causing the pig industry practitioners of high concern.
November 18, 2019, the Ministry of Agriculture and Rural Affairs website issued a notice that so far, including China, countries around the world have not approved the sale of the commercial use of African swine fever vaccine.
so-called "African swine fever test seedlings, home seedlings, imported seedlings", in accordance with the "Veterinary Medicine Regulations", are illegal vaccines, should be treated according to fake veterinary drugs.
officials have not given an explanation as to whether the african swine fever virus, which is currently missing genes, was caused by an illegal "African swine fever vaccine".
experts say this needs to be determined by genetic sequencing, and no results have yet been available.
