Statistical data were analyzed by SPSS 17 software and used descriptive statistical tests. Results: The results show that the 52.9% (n=55) was infected. Most types of microbial contamination associated with coagulase negative staphylococcus strains with 36.4% (n=20) and the least polluting type associated with enterococci 9.1% (n=5). Comparing the intensity of the treatment units showed the most is relevant to the operating room and the lowest in pediatrics and surgery in men.
