Query: Current Status of Nucleon Decay Searches with Super-Kamiokande   Evidence for Nucleon Decay has yet to be observed. Current results from the
observation of a 45 kton-year exposure of Super-Kamiokande and lifetime limits
for nucleons to decay via lepton + pion, lepton + eta and lepton + kaon modes
are presented.
