This review presents the results of an informal 1993 survey of the distribution of chimpanzees (Pan troglodytes) in the world's laboratories, and the types of research conducted on them. Based on the available information, there are over 2200 chimpanzees in.laboratories, most of which are located in several US facilities. Europe apparently has less than 200 chimpanzees housed in two facilities. Worldwide, an estimated 80% of the chimpanzees in laboratories are used in studies on AIDS and hepatitis. It is concluded that, if Europe terminated its use of chimpanzees in research, for either financial, moral or political reasons, the impact on experimental research would be relatively minor.
