FATAL DISSEMINATED ENCEPHALITOZOONOSIS IN A CAPTIVE, ADULT GOELDI'S MONKEY (CALLIMICO GOELDII) AND SUBSEQUENT SEROSURVEY OF THE EXPOSED CONSPECIFICS
2008
Abstract A captive, adult male Goeldi's monkey (Callimico goeldii) (GM) presented in acute respiratory distress 4 yr after importation into the United States from Europe. Radiographs and echocardiogram were consistent with heart failure. The monkey died within 24 hr of presentation. Necropsy findings included multicentric arteritis and aortitis with aneurysm associated with microsporidian organisms morphologically consistent with Encephalitozoon species. Polymerase chain reaction confirmed organisms were Encephalitozoon cuniculi. Sequence analysis of amplicons generated by using primers specific for the polar tube protein of E. cuniculi determined the organism to be genotype II. An E. cuniculi serosurvey of potentially exposed conspecifics that represented approximately 40% of the captive GM population in the United States was conducted. Multiple individuals that had been imported from Europe with the individual of this report were seropositive via an immunofluorescent antibody assay for E. cuniculi. Mult...
