[Isolated bacteria from nasal cultures. Are they important in patients with acute leukemia?].

Background: The nasal colonization by Staphylococcal (epidermidis or aureus) is frequent and it has importance when it is associated to bacteremia in immunocompromised patients. The objective was to determine the frequency of strains that colonize the nasal mucosa in patients with leukemia and its relationship with peripheral blood cultures.
