Colonization of venous leg ulcers by microorganisms.

The aim of the study was to identify the microorganisms that most commonly colonize leg ulcers. The study included 70 patients of both sexes, aged 31-85 years. There were 49 (70%) female and 21 (30%) male patients, mean age 69.16 and 61.62 years, respectively. Nineteen different types of microorganisms were isolated in study patients: one in 18, two in 38, and three pathogens in 13 patients. Only one of study patients had four microorganisms isolated at the time. The most common microorganisms were Pseudomonas aeruginosa found in 25 and Streptococcus aureus in 19 patients.
