[Epidemiology of the resistance to antibiotics at the Hospital Center of Aulnay-sous-Bois].

Over the 14 month period (1/6/87-1/8/88) the majority of the bacteremia observed in the intensive unit (C.H. d'Aulnay) was due to Gram-positive bacteria (16/23 cases). The incidence of resistant to methicillin Staphylococcus aureus (SAMR) in blood culture was 10% in 1986 and 14% in 1987. Resistance of S. pneumoniae to penicillin was not detected; 30% of the 72 strains were resistant to erythromycin and 26% to tetracycline. Among Enterobacteriaceae, third generation cephalosporin is uncommon (2.8%) as gentamicin resistance (4.5%). Among the anaerobes, 57% of non Bacteroides fragilis group are resistant to penicillin. Nitroimidazole resistance was not detected.
