La résistance bactérienne des souches de la flore buccale

Abstract

Bacterial resistance is a growing concern for public health and clinical practice. The mouth is home to a wide variety of microorganisms, some of which can become pathogenic and develop antibiotic resistance mechanisms. This resistance can lead to more difficult to treat oral infections, requiring the use of more powerful and expensive drugs, and increasing the risk of serious complications. Hence the interest of isolating bacterial strains of oral origin responsible for oral infections in order to assess their sensitivity to antibiotics. This study presents the biological fractionation guided by the antibacterial activity in vitro of several families of antibiotics, evaluated against staphylococci, enterobacteria and streptococci. After submission to an antibiotic sensitivity test, although the strains were sensitive to at least one antibiotic, the resistance rate remained high. The effect of various VA concentrations to obtain a minimal inhibitory concentration (MIC) was studied on streptococci, revealing a real antibacterial activity.
