Antibacterial Activity of Citrus Juices against Methicillin Resistant Staphylococcus aureus

Abstract

This study aimed to see the inhibitory activity of Citrus Juices against methicillin resistant Staphylococcus aureus,and to compare with the inhibitory activity of some antibiotics. Several Citrus juice concentration of 100%,75%,50% and 25%, which were diluted with distilled water after filtration through bacterial filter(Millipore).Result indicated that the best antibacterial activity was observed in 100%,75%,50% and 25% (v/v) concentrationsfor the three types of Citrus juices only but there were no antimicrobial activities in 100%,75%,50%and 25% concentrating for the one types of Citrus juices that C.tangerina (mandarin orange)on same bacteria,on the other hand all the 30 MRSA isolates showed a high level of resistance to aminoglycosides group, with rate reached to 5 isolates (16.6%) for streptomycin,11isolates(36%)for amikacin,15 isolates (50%) for gentamicin,19 isolates(63.3%)for kanamycin. All the isolates showed sensitive for streptomycin antibiotic, the isolates showed these resistance to all antibiotics amikacin, gentamicin, kanamycin .
