A^^Sl " ^5"^ '' ' ^'^'"^ ^"'^' '"^''^^ "«"«^i•^ disease of captive South A•• marmosets and tamarins (Callitrichidae), including the endangered goWen lion ta mann. A common-source outbreak of CH in golden lion tamarins and pygmy marmosets at a US zoo resulted from a single feeding of the primates with newborn mice in^ppLnTirSei wkh tymphocyttc chonomeningitis virus (LCMV). Isolates from livers of n^ce and primats we t related to isolates from previous CH outbreaks and to laboratory strains of LCMV nw ^d nucletc acid hybridization, and 2 surviving animals devejed antiLdy toXeÍLCM^ «^a es and to laboratory strains of LCMV. Thus, LCMV, an arenavirus prevalent ^ wHd n^^ m the US, can cause sporadic fatal hepatic disease in primates. Exposure of humans to wild or laboratory mice or to marmosets and tamarins that are infected with wild-type strains of LCMV poses the danger of serious disease.
