PUBMED DOIAdditional Information
Our objectives are research into well-established autochthonous viruses (Toscana, West Nile and Lymphocoriomeningitis), imported viruses with a vector in Spain (mainly Zika, Dengue and Chikungunya), and viruses that cause haemorrhagic fevers (such as Ebola, Lassa or Crimea Congo, which despite being autochthonous, we include in this category) without forgetting other viruses that, at any time, may become emerging viruses and cause public health alerts.
The group's main research objective is to identify and characterise the aforementioned viruses that cause disease and those circulating in our environment with pathogenic potential.
One of the cross-cutting objectives of the laboratory is to optimise methods for the detection of these viruses and their application to determine the incidence, prevalence and/or presence of the viruses in our environment.
However, in addition to methodological development, it is important to know the origin of the circulating viruses, their antigenic relationships with related viruses, the pathogenicity of the different isolates or the interactions of the agents with their host both in cell culture and in arthropod vectors when this is possible. The aim is to strengthen our role as a National Reference Laboratory for zoonoses through research.
