Antibiorèsistance des Bactéries Hospitalières

Abstract

Bacteria exposed to antibiotics evolve and develop defense mechanisms that allow them to escape their action by rendering them ineffective. For this, the objective of this study is to determine the profile of the antibiotic resistance of certain germs isolated in a hospital environment, in the city of Ain Témouchent, from different types of samples (urine and pus). The results obtained show that among the isolated strains E coli is the predominant (51.22%) followed by Staphylococci (22.36%) then Enterobacter (16%). This bacterium is much more common in children (61%). The antibiogram revealed a very high or even alarming resistance to many antibiotics such as oxacillin (89.68%), amoxicillin (85.41%), penicillin (76.41%), amoxicillin clavulanic acid (64, 28%) and vancomycin (63.91%). gentamicin and ofloxacin retain a good action on the strains studied (18% and 15% respectively). E coli strains have the highest rates of antibiotic resistance. The results of multi-resistance are extremely worrying because 71% of our strains are resistant to at least 2 different antibiotics, 40% are resistant to at least 3 different antibiotics and only 5.69% of them are perfectly sensitive.
