The Mycobacteria Unit (MYC) routinely conducts immunological, bacteriological, and molecular diagnosis of infections caused by mycobacteria, primarily tuberculosis. Additionally, it carries out field and experimental studies to evaluate diagnostic techniques and vaccines for the design of control and eradication strategies, as well as molecular epidemiology studies based on different techniques including sequencing. Therefore, the main research lines of the group involve the development, evaluation and fine-tuning of methodologies for in vivo and in vitro diagnosis of infections caused by mycobacteria, as well as the development of new technology for molecular characterization studies. MYC also collaborates with the Official Veterinary Services of Spain to design strategies that improve control and eradication programs for tuberculosis in domestic ruminants, as well as in the improvement of diagnosis and control in other domestic and wildlife species. Additionally, MYC participates in training courses and conferences on various aspects of tuberculosis aimed at veterinarians and livestock farmers. Thanks to the professional trajectory of this group, the VISAVET Centre was designated in 2008 as the European Union Reference Laboratory for bovine tuberculosis, under the auspices of the European Commission, providing technical support to all National Reference Laboratories (NRL) as well as the official veterinary services of the European Union. Furthermore, in 2023, it was also designated as the Reference Laboratory for mammalian tuberculosis by the World Organisation for Animal Health (WOAH), expanding its technical and scientific work beyond the European context.
