Antimicrobial resistance of strains isolated in sputy samples

Abstract

An investigation was carried out in the Microbiology Laboratory of the Provincial Center of Hygiene Epidemiology and Microbiology (CPHEM) in the period of January-March 2009, with the objective of determining antimicrobial resistance in 73 strains isolated from microorganisms and identified Sputum samples from patients with low respiratory infections. The susceptibility and resistance to antimicrobials in vitro are determined by Bauer Kirby's method. The results are expressed in two-dimensional table and the summary measure used was the percentage. The largest number of bacteria identified corresponds to gram-negative bacilli. The highest resistance is shown by Pseudomonas aeruginosa, followed by Staphylococcus aureus and Klebsiella pneumoniae. It is concluded that antimicrobial resistance is an emerging problem, which requires its adequate selection and identification of the etiological agent.
