  We show that high-energy neutrinos can be efficiently produced in X-ray
binaries with relativistic jets and high-mass primary stars. We consider a
system where the star presents a dense equatorial wind and the jet has a small
content of relativistic protons. In this scenario, neutrinos and correlated
gamma-rays result from pp interactions and the subsequent pion decays. As a
particular example we consider the microquasar LS I +61 303. Above 1 TeV, we
obtain a mean-orbital neutrino muon induced luminosity of 5 10^34 erg/s which
can be related to an event rate of 4-5 muon-type neutrinos per
kilometer-squared per year after considering the signal attenuation due to
maximal neutrino oscillations. The maximal neutrino energies here considered
will range between 20 and 85 TeV along the orbit. The local infrared
photon-field is responsible for opacity effects on the associated gamma
radiation at high energies, but below 50 GeV the source could be detected by
MAGIC telescope. GLAST observations at photon energies E>100 MeV should also
reveal a strong source.
