Abstract African swine fever (ASF), caused by the African swine fever virus (ASFV), is a devastating disease of domestic and wild pigs. (chinaagrisci.com)
However, the antibodies against these proteins do not provide efficient protection against ASFV infection in pigs. (chinaagrisci.com)
This assay and a commercial ELISA kit were then used to detect 60 field pig serum samples, including an unknown number of anti-ASFV sera. (chinaagrisci.com)
Furthermore, the pB602L-based ELISA was employed to test the antibody responses to the seven-gene-deleted ASFV strain HLJ/18-7GD in pigs. (chinaagrisci.com)
One objective of the study was to determine whether rodents trapped in and around ASF-infected farms harbored ASFV (African swine fever virus), and if so, the optimal samples to obtain from rodents to detect viral infection. (swinehealth.org)
Building on the negative results from Experiment 1, the second experiment examined whether rats were susceptible to challenge with ASFV, and if so whether they were able to transmit the virus to susceptible rodents. (swinehealth.org)
Despite robust challenges both intraperitoneally and orally, rats were not observed to become ill from nor infected with ASFV out to an incubation period of 21 days. (swinehealth.org)
Despite efforts made over past decades, there is no vaccine or treatment available for preventing and controlling the ASF virus (ASFV) infection, and there is an urgent need to develop novel strategies. (mdpi.com)
African swine fever virus (ASFV) is a complex nucleocytoplasmic, large DNA virus that infects both domestic pigs and wild boar, but little is known about the process of genomic replication. (bvsalud.org)
We also showed that pE301R interacted with the ASFV genome and viral DNA polymerase O174L. (bvsalud.org)
More importantly, T2 amino alcohol, a PCNA-specific inhibitor, markedly inhibited ASFV replication at the stage of viral genome replication. (bvsalud.org)
This study not only highlights the functional role of the ASFV pE301R as a viral sliding clamp analog, but also facilitates the dissection of the complex replication mechanism of ASFV, which provides novel clues for developing antivirals against ASF. (bvsalud.org)
This group of researchers wanted to evaluate the survivability of ASF virus (ASFV) in tissues and body fluids from experimentally infected domestic pigs and wild boar, which were stored in different tissues and at different temperatures. (swineweb.com)

In South Korea, African swine fever virus (ASFV) has spread among wild boars through Gangwon-do to Dangyang-gun, Chungcheongbuk-do on the southern border of Gangwon-do. (e-jecoenv.org)
To prevent the spread of ASFV to African swine fever (ASF)-free areas, it is necessary to identify areas with a high probability of finding ASFV-infected carcasses and to reduce the density of wild boars in those areas. (e-jecoenv.org)
In this study, we described the propagation trend of ASFV among wild boars, constructed the habitat suitability maps for ASFV-infected carcasses, and suggested areas with a high probability of finding ASFV- infected carcasses and an important route of ASFV transmission. (e-jecoenv.org)
Despite the active quarantine policies in Korea to prevent the spread of ASFV through wild boars, there was no significant difference in the monthly average of number of ASFV-infected carcasses observed between 2020 and 2021. (e-jecoenv.org)
The ASFV-infected carcasses were found more in winter and spring (January to April). (e-jecoenv.org)
The habitat suitability map, based on GPS coordinates of ASFV-infected wild boar carcasses, shows that highly detectable areas of ASFV-infected carcasses were sporadically dispersed in western and southwestern parts of Gangwon-do, and ranged from north to south of the province along the Baekdudaegan Mountains, whereas poorly detectable areas ranged along the north to the south in the middle parts of the province. (e-jecoenv.org)
Our suitability model, based on the GPS coordinates of ASFV-infected carcasses, identifies potential habitats where ASFV-infected carcasses are likely to be found and ponential routes where ASFV is likely to spread. (e-jecoenv.org)
Among ASF-free areas, the areas with high suitability predicted in this study should be given priority as survey areas to find ASFV- infected carcasses and hunting areas to reduce wild boar populations. (e-jecoenv.org)

It's why scientists have been working on another type of vaccine, made from a weakened virus rather than a dead one. (leaderherald.com)
In China, the government indicated scientists are working on a vaccine that genetically alters the virus, an approach U.S. scientists have been pursuing as well. (leaderherald.com)
But before a vaccine becomes available, it needs to be tested in large numbers of pigs in secure facilities with isolation pens, waste and carcass incinerators and decontamination showers for staff, said Linda Dixon, a biologist at London's Pirbright Institute, which studies viral diseases in livestock. (leaderherald.com)
In the 1960s, for instance, Spain and Portugal tested such a vaccine after outbreaks of African swine fever. (leaderherald.com)
A vaccine might be most desirable in places where the disease is widespread, said Daniel Rock, who previously headed Plum Island's African swine fever program. (leaderherald.com)

(cdc.gov)
They'll observe how the viral genome interacts with the host, and then zero in on the genes that seem most important, potentially identifying new pathways for a vaccine - or for the development of an effective antiviral drug. (feedstrategy.com)
In this case, Graham said, his team plans to trial the use of a PRRS vaccine that is built using DNA rather than the virus itself. (feedstrategy.com)
Graham said the team's plan for their study is to follow the DNA vaccine with a second dose of a more conventional vaccine made from live modified virus to see if the DNA-based vaccine does in fact boost the efficacy of future doses. (feedstrategy.com)
The virus in the second vaccine will also be genetically engineered to induce even greater protection using an emerging technique that uses natural processes called immune checkpoint inhibitors to regulate how the immune system responds to the vaccine. (feedstrategy.com)
History has proven, an effective vaccine is developed after the origin of the virus is discovered. (usa-evote.com)
With the technology today, the origin of a virus can be easily traced, identified, and studies can lead to a safe and effective vaccine. (usa-evote.com)

The pdm09 strain of influenza A has jumped from humans to swine approximately 370 times since 2009, leading to the evolution of variants that have then crossed back to humans. (scitechdaily.com)
Influenza A can cause the flu in humans, birds, swine, and some other mammals. (scitechdaily.com)
Since then, as demonstrated in prior studies, pdm09 has repeatedly passed from humans to swine, and circulation of the virus among swine leads to evolutionary changes in pdm09 that could make it more likely to cross back and infect humans. (scitechdaily.com)

(feedstrategy.com)
Although there are already several several functional ASF vaccines in the works , Chris Netherton, head of the African swine fever vaccinology group at Pirbright, said it remains difficult to distinguish vaccinated pigs from pigs that are infected with the virus and capable of spreading it. (feedstrategy.com)
Vaccines against these diseases, he said, are also made using weakened versions of the virus. (feedstrategy.com)
B vaccines were concentrated in New York City, San Francisco and central Africa. (hpathy.com)
The researchers found that most human-to-swine transmission events were isolated, but a few led to the sustained circulation of different pdm09 genetic lineages among swine in the U.S. These swine-circulating variants appeared to be genetically poor matches for human seasonal vaccines, suggesting that the vaccines would have provided scant protection against them.
