News sequences types of Staphylococcus aureus isolated from human pathologicals fluids in Burkina Faso

Abstract

Abstract Staphylococcus aureus is a pathogen with high epidemic potential frequently involved in nosocomials and communities infections. The pathogenicity of Staphylococcus aureus is due to both its ability to resist antibiotics and to Produce toxins. This work aims at studying the resistance and Molecular Epidemiology of Staphylococcus aureus. Antibiotic susceptibility of the 70 strains isolates of Staphylococcus aureus was determined by agar diffusion while Multiplex PCR and MLST were used to search toxin-coding genes and MRSA typing, respectively. 14.28% of isolates were multidrug resistant. Staphylococcus aureus showed high susceptibility to aminoglycoside and Macrolides familly. lukS-PV/lukF-PV and sea genes were detected in 45% and 3% of Staphylococcus aureus respectively. Ten (10) sequence types including ST5710, ST2430, ST5289, ST5786, ST6942, ST6943, ST6944, ST6945, ST6946, ST6947 have been reported. The study showed a diversity of antibiotic resistance phenotypes and a great diversity of MRSA clones causing infections.
