Over the past three decades, intensive studies of murine schistosomiasis ha
ve provided important clues to the understanding of the human disease, but
growing evidence suggests that these results derived from highly inbred str
ains of mice might not have direct applicability to the human infection. Re
cent data based on the baboon indicate that infection in this non-human pri
mate might mirror the human situation. In this review, Mramba Nyindo and Id
le Farah demonstrate that baboons provide an excellent non-human primate mo
del that produces pathology and disease closely resembling that observed in
humans, and address how studies in baboons can provide insights into mecha
nisms regulating schistosomiasis mansoni pathology and immunity. They also
address, in a general way, issues related to the use of non-human primates
in biomedical research.
