Abstract

The purpose of this study is to evaluate the quality of endoscope disinfection at teaching Hospital of Marrakech between March 1st and June 1st, 2015. It is a prospective study of the results of microbiological tests carried out at the teaching Hospital of Marrakech between March 1st and June 1st 2015 over a period of 3 months, with digestive endoscopes. The sampling and the interpretation of the microbiological results were carried out according to the recommendations of the Technical Committee for Nosocomial Infections and Infections Linked to Health Care) (CTINILS). The results obtained showed a residual contamination of total aerobic mesophilic flora (FMAT) at the order of 4,9.103 CFU/ endoscope. 12 microorganisms were isolated and identified. Pseudomonas spp. was the most frequently isolated bacteria in these samples, (47% of all positive samples). The rest is shared between Micrococcus spp (15%), Staphylococcus spp (23%) and Bacillus spp. (10%). The corrective measures established concerning the disinfection procedure adopted in the service made it possible to eradicate the contamination at a target level (FMAT <10 CFU / endoscope). The respect of the basic principles of hospital hygiene and the application of rigorous cleaning and disinfection procedures are major elements in the prevention and fight against nosocomial infections.
