The veterinary services of the Catalan Regional Government have notified the Ministry of Agriculture, Fisheries, and Food of the detection of two wild boars positive for African swine fever virus in Bellaterra (Barcelona), where they were found dead on November 26. These cases represent the first detection of the disease in Spain since November 1994, according to the ministry in a press release. African swine fever is considered a Category A disease by the European Union, which means that member states must take measures to control and eradicate it as soon as possible. It is a non-zoonotic disease, meaning that humans are not susceptible to infection either through contact with animals or through the consumption of animal products.

An international team has used the CRISPR gene-editing tool to modify a key gene for the replication of the classical swine fever virus in pigs. The experiment, conducted on four animals, showed complete protection against the disease. According to the researchers, this breakthrough could serve as an additional method for controlling this type of virus, which entails significant economic and animal welfare costs. The results are published in the journal Trends in Biotechnology.
