<< Background >>Mouse-based studies are essential for deciphering the genetic basis of human diseases. However, there is a proven European and global significant deficiency of formal and specialized courses to acquire the necessary expertise in Mouse Pathobiology, especially in Higher Education. For this reason, universities, research institutions and companies, have come together to establish the PATHBIO consortium and to develop new training opportunities to change this reality.<< Objectives >>The PATHBIO objectives have been: 1. To respond to the increasing need of well-prepared professionals in the area of Mouse Pathobiology 2. To identify the main challenges for professionals working in the area of Mouse Pathobiology 3. To include new areas of knowledge and technologies in the field of Mouse Pathobiology 4. To implement an integrated European educational approach in Mouse Pathobiology<< Implementation >>The PATHBIO consortium has implemented all of the objectives envisaged in the Erasmus+ proposal, obtaining a significant impact on the target audience that has been confirmed by the external evaluation measures. Due to COVID-19 pandemic and the global restrictions, and after consultation with the Agency, PATHBIO adapted the 2020 and 2021 main events to a virtual and dual (face-to-face and on-line) formats.<< Results >>Main outputs of the PATHBIO project have been: a) Organization of three Summer Course editions with the participation of 383 students from 47 countries (28 non-European) and 60 lecturers from 13 different countries (4 non-European) b) Deployment of a Virtual Learning Platform including 270 on-line lectures c) Elaboration of 7 new teaching materials for Mouse Pathobiology d) Design of a Master program on Mouse Pathobiology submitted to the Erasmus Mundus calls in 2021 and 2022
