  We present here the results of a search for new microquasars at low galactic
latitudes, based on a cross-identification between the ROSAT all sky Bright
Source Catalog (RBSC) and the NRAO VLA Sky Survey (NVSS) and follow-up
observations. The results obtained up to now suggest that persistent/silent
microquasars such as LS 5039 are rare objects in our Galaxy, and indicate that
future deeper surveys, and harder than the RBSC in X-rays, will play a
fundamental role in order to discover them.
