Title : Pathology of mara (Dolichotis patagonum)
Authors : A. BATARD et J. DUCOS de LAHITTE
Summary : Maras or Patagonian cavies (Dolichotis patagonum) are large Rodents indigenous to Argentina. Although they are commonly kept in zoos, there is little information available about their diseases. Trauma is the most common cause of death ; cases are due to fighting between the maras, attacks by other species or maras injuring themselves. Then, there is a high prevalence of infectious diseases. Indeed, maras are particularly susceptible to pseudotuberculosis (or yersiniosis), a letal disease occurring mainly on winter months, in European zoos ; the species can suffer from other zoonotic diseases : cowpox infection, characterised by high pathogenicity (extensive pox lesions, shedding large amounts of viral particles) and disseminated histoplasmosis. Parasitic diseases are also frequently observed : flea ectoparasitism, lice infestation and gastrointestinal parasitism by nematodes ; besnoitiosis is described in maras, too. Besides, maras seem to be subject to high altitude disease and predisposed to hyperthermia associated with capture and anaesthesia. Other recorded diseases concern isolated cases.
