Characterization of multidrug-resistant strains isolated from medical intensive care units in Cali - Colombia.

Introduction: The extensive use of antibiotics has led to the emergence of multi-resistant strains in some species of the genus .

Objective: To investigate the molecular characteristics of multidrug-resistant of strains isolated from 52 patients collected between March 2009 and July 2010 in medical intensive care units in Cali - Colombia.

Methods: The susceptibility to various classes of antibiotics was determined by disc diffusion method, and the determination of the genomic species was carried out using amplified ribosomal DNA restriction analysis (ARDRA) and by sequencing of the 16s rDNA gene.

[Phenotypic characterization of Acinetobacter baumannii isolates in a high-complexity healthcare institution in the city of Cali].

Introduction: Phenotypic characterization of the Acinetobacter genus bacteria through biochemical and microscopic tests is possible. Studies have shown that the isolates from health-care associated infections show high resistance to first-line antibiotics.

Objective: To describe the resistance patterns of the A.
