PROFESSOR BIO INFORMATION

Mariano Domingo is a Veterinary Pathologist with strong background and knowledge of pathogenesis and pathology of animal diseases, and with a long experience in diseases of Marine Mammals. Since 1990 he is an active participant in the stranding network led by the Catalan Government, performing necropsies of stranded cetaceans, and determining the causes of death. He is a trainer in Marine Mammal Pathology for the residents of the European College of Veterinary Pathologists in the three last editions of this topic in the ECVP summer school. He is author of 180 scientific articles on animal diseases, 36 of them related to wild animals, and 20 of them referring to diseases of cetaceans.

ACADEMIC GUIDE

Contents overview

The subject will be dedicated to a general description of the main diseases and threats that affect cetaceans (dolphins and whales) and pinnipeds (seals and sea lions) in the world. The course will review the main conditions that affect these species, with an interdisciplinary view, ordered etiologically (bacterial, viral, parasitic, anthropogenic and other non-infectious problems).

It will include theoretical and practical sessions. The theoretical classes will cover the core knowledge of the different diseases and conditions, including aetiology, pathogenesis, clinical signs and lesions, and diagnostic procedures, and impact on the populations. Diseases will be described using specific individual cases with archive material and images. Information will be extended with basic references and chapters on each topic, made available to the students one or several days in advance to discussion in the class.

Methodological aspects will also be taught, with introduction to the different methodologies of disease detection and investigation of specific causes of death. As part of the practical training, a full necropsy of a dolphin (frozen and thawed for the course) will be performed by the students at the necropsy room of the Veterinary Faculty. Information on diseases will be complemented with practical lectures using the microscope and visualizing slides of specific diseases at the microscopy laboratory.

Discussion of selected papers (presentation by groups of 2-3 students)

Evaluation (written exam).

 

Evaluation

Students will have to present orally in the class a critical review of a scientific paper, performed in groups of 2-3 students, following a pre-established format. This presentation will receive a qualification (40% of the note). Students will complete a written examination with short questions and answers (60% of the note). The final qualification will the sum of both qualifications. Evaluation will be completed two days before the end of the 3rd week of the course.
