Comparative analysis between colonization and infection strains starting from statistical methods.

摘要: Isolated colonization strains of preoperative patients were compared with isolated infection surgical patients, seeking to establish compatibility relationships that can suggest a possible common origin between them. Sixty from Hospital Universitario Pedro Ernesto, Rio de Janeiro, Brazil, have used cephalotin as pre-surgical prophylaxis, studied the intestinal, oropharyngeal and cutaneous for cephalotin-resistant bacteria, using selective culture media. The through antibiogram analysis other 2005 clinics. Statistical methods such Qui-square Mann-Whitney U tests employed comparison frequencies species numbers resistance markers antimicrobials. microorganism infections represented 62,8% detected among 2065 patients. average number antimicrobials was higher strains. There no significant differences when markers, most microorganisms. Cephalotin has proved be an effective marker detection multiresistant results indicate possibility populations colonize inpatients related microorganisms cause in these
