ABSTRACT

The present work aims to evaluate the antimicrobial potential of solvent extracts of Catharanthus roseus on some food pathogens. Agar well diffusion method has been used to determine the antimicrobial activities against biofilm and betalactamase producing bacteria. Among the 3 solvent extracts, methanol extract showed exciting activity against all bacterial isolates. The lowest MIC value was observed while using methanol extract; 0.25mg/ml was MIC for P.aeruginosa, K.pneumoniae and S.aureus. Furthermore, isolates of cell surface hydrophobicity were reduced with those plant extracts. Among the solvent extracts, acetone extract showed better activity against bacterial hydrophobicity. This study suggested the suppressive potential of plant extracts against the bacterial isolates and their hydrophobicity, hence can be used as natural alternative preventives to control the bacterial isolates. Keywords: Food pathogens, Biofilm, Betalactamase, Catharanthus roseus, Hydrophobicity
