Confirms EMCV myocarditis in bonobos; hypothesis-generating for primate surveillance and exposure risks.
BACKGROUND: Fatal myocarditis from encephalomyocarditis virus (EMCV) infection has previously been identified in sporadic and epidemic forms in many species of captive non-human primates probably including one bonobo (Pan paniscus). METHODS: We investigated the deaths of two bonobos that were suspicious of EMCV using a combination of histopathology, immunohistochemistry and, for one of the two bonobos, reverse transcription PCR. RESULTS: Histopathological examination of heart tissue from the two bonobos showed changes characteristic of EMCV. Immunohistochemical studies confirmed the presence of EMCV antigen in heart tissue of both and in kidney and intestine of one of the bonobos. EMCV RNA was also isolated from the serum of the bonobo tested. CONCLUSION: Together, these findings confirm that EMCV was responsible for deaths of the two bonobos. Strict separation of bonobos in particular and captive primates in general from potential sources of EMCV contamination should be maintained to prevent mortality caused by EMCV.
