Introduction Clostridium difficile is a Gram-positive bacillus, anaerobic, sporogenous ,with oro-faecal transmission.The formation of the spores can persist in a long time, encouraging the transmission. Use of broad-spectrum antibiotics, age, alteration of intestinal flora are the most common risk factors that expose the subject to any subsequent colonization and infection. The hospital staff is the main vehicle of transmission and the probability of contracting an infection is proportional to the duration of hospitalization in patients infected with cohabitation. Objectives The infections surveillance of C. difficile is a instrument to monitor procedures for the control of hospital infections, and may be useful to highlight and point out shortcomings in the system. Materials and Methods The data are the results of tests for the detection of toxins on stools during the period 2004-2006, distributed quarterly to study the seasonal, divided by individual UO the hospital and later for area hospital. Results and conclusions The incidence of infection from C. difficile in the last three years has been in constant increase (from 7 to 12.5 case/1000 admissions). Much of increase is attributable to community infections 3 case/1000 admissions (2004) up to about 6 case/1000 admissions (2006). Substantially increasing content of hospital infections (5-6 case/1000 admissions).
