  A detailed abundance analysis of 5 giants of the metal-rich bulge globular
cluster NGC 6553 was carried out using high resolution infrared spectra in the
H band, obtained at the Gemini-South 8m telescope. JK photometry collected at
ESO and VI photometry from the Hubble Space Telescope are used to derive
effective temperatures. The present analysis provides a metallicity [Fe/H] =
-0.20 +/- 0.10. An overabundance of oxygen of [O/Fe] = +0.20 is found from IR
OH lines.
