  We report on the archival near-infrared and mid-infrared observations of 7
persistent X-ray sources situated in the Galactic bulge using data from the
UKIRT Infrared Deep Sky Survey (UKIDSS), Spitzer Galactic Legacy Infrared
Mid-Plane Survey Extraordinaire (GLIMPSE) and the Wide-field Infrared Survey
Explorer (WISE) all-sky survey. We were able to successfully identify, or
provide upper flux limits for the systems SAX J1747.0-2853, IGR J17464-2811, AX
J1754.2-2754, IGR J17597-2201, IGR J18134-1636, IGR J18256-1035, Ser X-1 and
constrain the nature of these systems. In the case of IGR J17597-2201 we
present arguments that the source accretes matter from the stellar wind rather
than via Roche lobe overflow of the secondary. We suggest that, at its X-ray
luminosity of $10^{34-35}$ erg s$^{-1}$, we are probing the poorly known class
of wind-fed low-mass X-ray binaries (LMXBs).
