Recherche des germes bactériens responsables des infections nosocomiales au niveau de 03 services (maternité - laboratoire d'hématologie et radiologie) de l'hôpital de Hammam-Bouhadjar, Ain-Temouchent

Abstract

Nosocomial infections are recognized as major public health problems by their frequency, their cost and their severity, which is why we have undertaken this study. During this work, three (03) medical services (Maternity, Radiology and hematology laboratory) within the « SIDI AYED » hospital of Hammam Bouhadjar Wilaya Ain Témouchent were proposed to perform this medical. We have isolated and purified ten (10) isolates. The latter were identified first by phenotypic methods and classical biochemical tests, then by the API 20E Gallery. The bacteriological results showed an important biodiversity of species. In total, 09 bacteria species have been identified. These species present very different morphological aspects and the number of bacterial isolates varies according to the department in which the analyzes were carried out. Unsurprisingly, the species Staphyloccocus aureus was present in almost all the isolates with the exception of the Radiology department. This germ appears to be the most dominant species among other bacterial germs. The results also revealed the presence of other bacterial species: Staphylococcus epidermidis, E.coli, Klebsiella Pneumoniae.ozaenae, Aeromonas hydrophila, Serratia odozifers, Serratia marcesens, Leclercia adecarboxylata and Enerobacter cloacea. According to the literature, St. aureus is today one of the most widespread germs and the most implicated in nosocomial infections. Antibiotic tests have shown the ineffectiveness of certain antibiotics against certain bacteria and effectiveness on other germs. The origin of the multidrug resistance observed seems to be linked to the use of antibiotics specific to each department, inducing a growing adaptation to these drugs which will probably not cease to spread.
