MARTINEZ BATISTA, María Luisa; HALLEY POSADA, María del Carmen; ESPINOSA RIVERA, Fidel  and  HART CASARES, Marcia. Isolates of Stenotrophomonas maltophilia in "Hermanos Ameijeiras" Clinical and Surgical Hospital in 2006. Rev cubana med [online]. 2008, vol.47, n.4. ISSN 0034-7523.

The strains of Stenotrophomonas maltophilia isolated in our laboratory were studied aimed at knowing the place it ocuppies according to its isolation frequency, its resistance patterns and the comparison with other non-fermentating bacilli. The identification up to species was carried out and the sensitivity was determined by the API ID 32 diagnostic system. Stenotrophomonas maltophilia occupied the 12th place among the most frequently isolated microorganisms in "Hermanos Ameijeiras" Hospital during 2006. 28 strains were isolated mostly from hemocultures. A very high resistance to meropenem and ceftriaxone was reported, even higher than in other non-fermentating bacilli as Acinetobacter sp and Pseudomonas, but with greater sensitivity to cotrimoxazole and ticarciline + clavulanic acid that are the main therapeutic alternatives.

Keywords : Antibiotic; bacterial strain; resistance; multiresistance.
