[Antibiotic resistance of the most frequently isolated germs at the Fann University Teaching Hospital between January 1999 and December 2000].
Bacterial infections take up an important place in tropical pathology and have an increased death-rate. Among the causes of this strong mortality, the resistance of bacteria to antibiotics keeps a dominant part. We carried out, between January 1999 and December 2000 a study aiming to establish the distribution of the most frequently isolated germs at the Laboratory of Bacteriology of Fann Hospital, their sensibility to antibiotics and the different phenotypes of resistance. We noticed a predominance of enterobacteria (69.30%), notably Escherichia coli (56.76%) and Klebsiella pneumoniae (47.69%), but also Staphylococcus aureus (13.91%). Enterobacteria present 39.7% of resistant phenotypes to beta-lactams (E. coli: 61.75% and K. pneumoniae: 47.69%). Only the third generation cephalosporins and fluoroquinolons are constantly actives on enterobacteria, and 69% of S. aureus strains are resistant to methicillin, and so to all beta-lactams. Pseudomonas aeruginosa become difficult to overcome: 51.13% of the strains produce beta-lactamase. The quinolons are the most active antibiotics on this germ. It is very important to settle network that will be in charge to survey the evolution of these bacterial resistances.
