Antibacterial Effect Of Zingiber Officinale On Staphylococcus Aureus

.ABSTRACT

The growing population concern about health has recently led to the development of natural

antimicrobials to control diseases. Medicinal plants and spices are one of the most commonly used

natural antimicrobial agents in food and have been used traditionally for thousands of years by

many cultures for controlling common health. Zingiber ojjicinale has long been used as

naturopathy due to their potential antimicrobial activity against different microbial pathogens. This

study was conducted to determine the antimicrobial activity of Zingiber ojjicinale rhizome on

Staphylococcus aureus. The present study showed the potent antimicrobial activity of the rhizome

extract against the tested bacterial pathogen, Staphylococcus aureus (Pl023) which was collected

from the Department of Microbiology, University College Hospital, Ibadan, Oyo State. Using the

disc method, 0.03mg/disc - 2.80mg/disc tested showed that only l.40mg/disc and 2.80mg/disc

inhibited the growth of the test organism, which gave a corresponding zone of inhibition of 14mm

and 17mm, respectively. The minimum inhibitory concentration (MIC) result showed that the least

concentration of the ginger extracts tested where no growth was recorded was with 125mg/ml while l 75mg/ml concentration proved to be the minimum bactericidal concentration (MBC).
