Microbiological monitoring of environment surfaces in a hospital in Fez city,Morocco

The hospital environment,colonized by many micro-organisms,is composed of true ecological niches. contamination by these microorganisms is diffuse. cumbersome procedures that are complex and costly are needed to master such contamination. the realization of a microbiological control of surfaces in a health facility is part of the policy for preventing nosocomial infections. it allows a better understanding of the microbial ecology for the purpose of conducting preventive and corrective actions. the aim of our study was to isolate bacteria from surfaces in a provincial public hospital in the city of fez. we analyzed a total of 81 samples of which 3 were negative. the identification of 89% of the bacteria isolated showed a predominance of bacillus sp (30%) and coagulase-negative staphylococci (24%). the proportions of the other identified germs were: staphylococcus aureus (9%),aeromonas salmonicida (7%),lactobacillus (6%),pseudomonas vesicularis and serratia rubidaea (3%) each,and e. coli (2%). a small proportion of 1% was contained photobacterium damsela,stenotrophomonas maltophilia,acinitobacter sp,pseudomonas aeruginosa and pseudomonas luteola. some gram negative cocci (5%) and oxidase positive gram-negative bacteria (6%) were also isolated but were not identified. current hand hygiene guidelines and recommendations for surface cleaning/disinfection should be followed in managing outbreaks because of these emerging pathogens.
