Porcine circovirus 2 (PCV-2) genetic variability under natural infection scenario reveals a complex network of viral quasispecies.

A study revealing the complex network of viral quasiespecies present under natural infection scenario of porcine circovirus 2 (PCV-2), was published recently by researchers from IRTA-CReSA in collaboration with a researcher from University of Padua (Italy).

African swine fever, frequently asked questions.

What is the current status of the African Swine Fever virus? What is the resistance of the virus? What are its transmission routes? And the forms of infection? What can we do to prevent it? Dr. Llilianne Ganges, IRTA-CReSA researcher and OIE expert on Classical Swine Fever virus answers these questions.

Viral comments (44): Postgraduate course in Biosecurity, the path is made by walking.

Last week finished the postgraduate course BIOSAFETY AND BIOCONTAINMENT STRATEGIES, taught in Spanish, coordinated academically by Dr. Antonio Villaverde and organized by the Faculty of Biociences and Faculty of Veterinary Medicine, with the support of the UAB’s Environment Office and of the Spanish Biosafety Association (AEBioS).

Viral comments (43): Endemic arboviral infections. Don’t got it, don’t got it, don’t got it…. Denguit!

We already have it here … perhaps it only comes to visit, or perhaps one should say that it returns to visit … we do not know if it’s for a few days or for many years.

First detection of the circulation of West Nile Virus on a horse in Catalonia

For more than 12 years IRTA-CReSA has been carrying out the diagnosis and technical assessment of the West Nile virus surveillance program in Catalonia as a service by the Departament d’Agricultura, Ramaderia i Pesca (DARP). This program was initiated with the objective of detecting early the circulation of West Nile virus, a virus that can affect wild birds and equids and is transmitted by mosquito vectors to people.

Viral comments (42): AEBioS 2018-A very diverse congress

Last week, from 3th to 5th of October, AEBioS, the Spanish Biosecurity Association held its 4th congress, this time in Salamanca.


From the 27th to the 30th of August an important International event, which gathered scientists from all over the world, took place in the “heart of Europe”, Vienna. The occasion welcomed the 11th International Congress for Veterinary Virology (ESVV) and the 12th Annual Meeting of EPIZONE in the same place, the prestigious University of Veterinary Medicine. ESVV-EPIZONE 2018 allowed attendants from different research centers, regulatory agencies and external partners to exchange new research outcomes and know the state-of-the-art of veterinary virology and its advances.

Innovation mornings: research in ecological livestock.

The Department of Agriculture, Livestock, Fisheries and Food (DARP) from the  Catalan Government organized a workshop on Ecological livestock on 20th September 2018. The main goal was to bring the livestock sector closer to the main research centers from Catalonia.

Application of MALDI-TOF assay for identification and differentiation of mastitis-causing pathogens from milk and non-milk samples

Matrix-assisted laser desorption/ionization time of flight (MALDI-TOF), a culture-dependent assay, is a rapid and reliable method that is able to identify a great variety of isolated bacteria. The MALDI-TOF works by using laser excitation of proteins to create a unique protein spectrum pattern of an unknown microorganism.
