A sample of events enriched in quark pairs was selected in the data recorded by the DELPHI experiment at LEP during 1992 and 1993, by the presence of secondary decay vertices from short-lived particles. Using this sample, the average multiplicities of K-S(0), K-+/-, p((p) over bar), Lambda() and of charged particles in events have been measured, distinguishing the component from fragmentation and the component coming from the decay of b-hadrons. The measurement of the average charge multiplicity in events was used to compute the mean fractional beam energy carried by the primary b-hadron, and the difference in charged particle multiplicity between events and light quark (, , ) events.
