ABSTRACT

Nosocomial infections are infections associated with healthcare and contracted in healthcare establishments. These infections are responsible for the many deaths and the increased cost of care. They are mainly related to poor hygiene practices in hospitals. Thus, the objective of this work is to assess the degree of microbial pollution in this hospital and the microbiological quality of the water. For this purpose, surface and water samples were taken by standardized methods. Then, microbiological analyzes were carried out in order to count the germs potentially responsible for nosocomial infections, germs indicating contamination and multi-drugs resistant germs according to standardized techniques. The results obtained show that the microbiological analyzes carried out on surfaces, indicate that there is a strong presence of germs in particular in the reception-emergencies rooms (1.64*1010 CFU / 25cm²), of the laboratory (7.108 CFU / 25cm²) , PMI (1.6*108 CFU / cm²) and Medicine / Pediatrics (6.38*107 CFU / 25cm²). In addition, multidrug-resistant germs have been identified in the samples from the emergency room, Medicine / Pediatrics and the laboratory. With regard to total and fecal coliforms, the surfaces are free from any fecal contamination. Aspergillus sp., Penicillium sp., Mycobacterium sp., Were also isolated and counted in these surface samples. As for the analysis of the various water samples, it indicates a strong presence of germs in the water from the borehole (1.8*108 CFU / mL). Neither coliforms (fecal and total) nor multidrug-resistant germs were isolated (0 CFU / mL). Aspergillus sp., And Mycobacterium sp., Were also identified in these samples. Ultimately, microbial pollution in the Hospital of the Medico-Social Center of the National Social Insurance Fund (NSIF) is mainly linked to poor environmental hygiene and sanitation.
