ABSTRACT

Background: Pneumonia is a frequent complication in patients under mechanic ventilation and it is also a severe consequence of Candida infection. Objective: To study samples from patients with mechanical respiration and to classify by automatized methods the different species of Candida. Methodology: Descriptive, transversal, and observational study. In a 12 months period we included all samples with Candida isolation from patients with respiratory mechanical ventilation. Results: We studied 440 samples from bronquial aspirates. We observed 296 positive bacterial cultures and yeasts were isolated in 42; 22 only with Candida. C. albicans 52%, C. tropicalis 24%, C. glabrata 19% and C. parapsilosis 5%. Discussion: Candida albicans was the most frequent yeast (52%), in both adults and children. Candida tropicalis (24%) was very important because its invasive potential and high tendency of resistance to azolic derivates. Candida parapsilosis (5%) is considered an emergent yeast in hospitalized children. Conclusions: In the identification of yeast we found very useful the automatized techniques. It is mandatory to perform a rutinary monitorization of respiratory samples in patients with a mechanical ventilation because others Candida species are reemerging as C. tropicalis and C. glabrata.
