Among the several threats to which free-ranging cetaceans are exposed, a number of biological noxae are believed to represent a serious hazard to their health and conservation on a global scale, with special emphasis on the Mediterranean Sea. These pathogens include viral agents such as Morbillivirus, which during the last 25 years have caused dramatic epidemics and die-offs among several aquatic mammal species and populations worldwide, as well as Herpesvirus, protozoan agents such as Toxoplasma gondii and bacterial pathogens such as Brucella spp.
