Herpesvirus outbreak in a group of mediterranean tortoises (Testudo spp).

ChHV and Mycoplasma agassizii infections in tortoises share similar clinical signs of lethargy, anorexia, rhinitis, and conjunctivitis. In addition, ChHV infection is associated with glossitis and stomatitis and often causes high morbidity and mortality. As was seen in this case, ChHV infection tends to cause higher mortality in T hermanni compared with T graeca and T marginata. T horsfieldi is also considered highly susceptible to ChHV but appeared unaffected in this outbreak.
