Abstract :
The objective of this work was to study at a molecular level the resistance genes of the ESBL-producing enterobacterial strains isolated at the Laboratory of Bacteriology and Virology of the CHNU Aristide Le Dantec and at the private laboratory Bio-24. The CTXM genes of group 1 (CTXM1) and the CTXM of group 9 (CTXM9) encoding for ESBL, OXA1 and CMY1 encoding for penicillinase and cephamycinase respectively were searched by PCR followed by nucleotide sequencing. The resulting sequences were submitted to the NCBI-Blast site for gene typing. The CTXM genes in Group1, CTXM in Group 9, OXA1 and CMY1 were found in 96%, 18%, 85% and 56% of the strains, respectively. Nucleotide sequencing of 15 CTXM1 allowed the CTXM15 to be recovered. These resistance genes can be associated with those of quinolones and/or carbapenems and thus lead to a therapeutic impasse, hence the need to strengthen the fight against antibiotic resistance.
