The hospital environment is comprised of a set of components that may come in contact with the patients. Persons such as the staff and the visitors are an integral part of this environment. In order to protect them, it is essential to control the hospital environment by identifying the sources of infections. Nosocomial infections have always represented a public health problem. For this purpose, we have carried out a study of bacteriological surfaces in the intensive care unit of the provincial hospital Elidrissi of Kenitra in Morocco. The objectives were the identification of different multi-resistant bacteria (MRB) and the determination of their distribution according to the sampling sites. On 120 samples collected, 30 MRB have been isolated where the Cephalosporinase hyperproducing Enterobacteriaceae is the most bacteria species identified. Below the bacteria identified and its number: · Cephalosporinase hyperproducing Enterobacteriaceae (10 strains).
· Acinetobacter baumannii (7 strains). · Stenotrophomonas maltophilia (5 strains).
· Staphylococcus aureus resistant to the methicillin (3 strains).
· Morganella morganii (2 strains)
· Pseudomonas aeruginosa (2 strains)
· Extended-spectrum betalactamase producing enterobacteriaceae (1. Strain)
The emergence of those bacteria constitutes a potential risk; however, the monitoring of the multi bacterial resistance has become a necessity and requires the establishment of an adapted strategy of intervention in order to avoid the risk of nosocomial infections.
